9 Health Benefits of Watermelon

Watermelon might be a summer fruit, but you tend to be able to find it all year round and you really ought to take advantage of its availability because, as it turns out, watermelon is incredibly good for you. So what are the health benefits of watermelon? Well, for one thing, it can help lower blood pressure in the obese. It’s also a natural diuretic that can help hydrate your body. It’s also a great sweet treat that’s still incredibly low in calories, and practically free from cholesterol and fat.

On a side note, if you’re having a little trouble in the bedroom, the fruit even works as a natural aphrodisiac and a natural Viagra when circulation is the problem.

1. L-citruline: Watermelon contains an abundance of an amino acid called L-citruline.

2. Alleviates high blood pressure.

3. Diuretic: Watermelon is a natural diuretic (as if the name isn’t a straightforward giveaway) and good for hydration.

4. Natural Viagra: In the area of improved circulation, one study has found that watermelon has Viagra-like effects where increased circulation is a necessity.

5. Vitamin and mineral rich: The body needs all sorts of vitamins and minerals to function.

6. Low in calories: A cup of watermelon contains about 80 calories.

7. Low fat: According to Nutrition Data, the big green fruit has almost no fat per serving, so…

Optimize Your Health – Eat, Move, and Sleep The Right Way

The human body is a highly evolved biological machine. You, as its owner, is obliged to look after its upkeep and maintenance. See to it that the nutrients it craves for are supplied consistently; so it can stay healthy, and vibrant always.

Another benefit you can acquire from taking care of your body is longevity. This fact has been proven by many studies and personally, I have talked to enough senior people who possess younger looking bodies, and they can still have long walks, swims, go biking, and still enjoy working. Wouldn’t it be nice to be able to do those activities in your twilight years?

Lifestyle plays a big role in optimizing your general health. It’s in your best interest to adopt a healthy one. I know its not easy to develop one; but, doing so can definitely do wonders for your body for the long haul.

I was hunting for good resources when I stumbled upon this infographic by Dans Plans. It illustrates how you can get your lifestyle on the right path to health and longevity. I would love to grow old with a healthy body. Wouldn’t you?

National Institute of Mental Health abandoning the DSM

In a potentially seismic move, the National Institute of Mental Health – the world’s biggest mental health research funder, has announced only two weeks before the launch of the DSM-5 diagnostic manual that it will be “re-orienting its research away from DSM categories”.

In the announcement, NIMH Director Thomas Insel says the DSM lacks validity and that “patients with mental disorders deserve better”.

This is something that will make very uncomfortable reading for the American Psychiatric Association as they trumpet what they claim is the ‘future of psychiatric diagnosis’ only two weeks before it hits the shelves.

As a result the NIMH will now be preferentially funding research that does not stick to DSM categories:

Going forward, we will be supporting research projects that look across current categories – or sub-divide current categories – to begin to develop a better system. What does this mean for applicants? Clinical trials might study all patients in a mood clinic rather than those meeting strict major depressive disorder criteria. Studies of biomarkers for “depression” might begin by looking across many disorders with anhedonia or emotional appraisal bias or psychomotor retardation to understand the circuitry underlying these symptoms. What does this mean for patients? We are committed to new and better treatments, but we feel this will only happen by developing a more precise diagnostic system.

As an alternative approach, Insel suggests the Research Domain Criteria (RDoC) project, which aims to uncover what it sees as the ‘component parts’ of psychological dysregulation by understanding difficulties in terms of cognitive, neural and genetic differences.

For example, difficulties with regulating the arousal system might be equally as involved in generating anxiety in PTSD as generating manic states in bipolar disorder.

Of course, this ‘component part’ approach is already a large part of mental health research but the RDoC project aims to combine this into a system that allows these to be mapped out and integrated.

It’s worth saying that this won’t be changing how psychiatrists treat their patients any time soon. DSM-style disorders will still be the order of the day, not least because a great deal of the evidence for the effectiveness of medication is based on giving people standard diagnoses.

It is also true to say that RDoC is currently little more than a plan at the moment – a bit like the Mars mission: you can see how it would be feasible but actually getting there seems a long way off. In fact, until now, the RDoC project has largely been considered to be an experimental project in thinking up alternative approaches.

The project was partly thought to be radical because it has many similarities to the approach taken by scientific critics of mainstream psychiatry who have argued for a symptom-based approach to understanding mental health difficulties that has often been rejected by the ‘diagnoses represent distinct diseases’ camp.

The NIMH has often been one of the most staunch supporters of the latter view, so the fact that it has put the RDoC front and centre is not only a slap in the face for the American Psychiatric Association and the DSM, it also heralds a massive change in how we might think of mental disorders in decades to come.

How to Create Pancakes for Health Nuts

When trying to stay healthy, it’s hard to see other people enjoying delicious pancakes and other baked goods that you might refrain from eating. However, with this quick and easy recipe (not to mention delicious!) you can make pancakes that taste even better than other people and are far healthier at the same time.

The best part about these healthy pancakes is how simple it is. You only need three ingredients to make these pancakes.

1. 2 ripe bananas
2. 1 egg
3. 1 tablespoon of almond butter

To make this, all you have to do is mash the bananas in a bowl until most of the lumps are completely gone. Add a single egg to the bananas and mix it all together until it is a (mostly) homogeneous mixture.

Mix it well!

batter-1

Your batter should look something like this. With this mixture, just scoop the size of pancake you would like on the pan (preferably using coconut oil!) and then watch as your banana batter turns into a delicious treat! Serve with berries (the bananas make them sweet enough already) or honey and you’re ready to go!

Yummm!

5 Small Hacks to Improve Your Health in 2013 and Beyond

Getting fit, eating right and living a healthy lifestyle are always some of the top resolutions every New Year. We all know in our guts that we should be living healthier happier lives and every year many of us find ourselves with the same predicament: we start off strong and then by February we’ve given up. Four weeks go by and we’ve come up with every excuse in the book to avoid getting off our bums and eating right—life gets in the way, work is taking too much of our time, we have to take care of our families, our friends think we’re nuts, etc. etc.

One solution that I have found incredibly helpful is to make small changes that really add up over time. We can allow incredible shifts to occur if we commit to taking small simple actions toward a bigger goal.

Below you’ll find easy and simple ways to improve your health through 2013 and beyond.

Beginning a meditation practice is one of the easiest ways to reduce stress and help with a multitude of emotional, mental and physical road blocks. The best part? It’s completely free! All you need is a few minutes and your breath. If you’re not sure where to start ,check out some Meditation Motivation tools to help you begin, and to keep your own meditation practice going through 2013.

Making green juices or smoothies for breakfast is probably the easiest way to ensure that you’re getting enough greens in your diet. The advantages of greens are endless, including changing the body from acidic to alkaline, helping with bowel issues, clearing up skin, and refreshing cells in the body.

For recipes, information on juicers, and more, check out Kris Carr, Healthy Cooking Camp, or any of Victoria Boutenko’s books.

Not having time to work out is one of the biggest excuses people use to not get off their bums. Here’s some news for you: if you’ve got 10 minutes free, you have enough time to work out. The best part? There’s no fancy expensive gym membership required! YouTube makes it extraordinarily easy to make sure you get in a good workout, even if you only have a few minutes. Simply do a search for your favorite fitness guru, or try one of several YouTube fitness celebrities. With time you’ll be able to make your own No Excuses Workout playlist.

If you’re not sure which workouts to aim for check out this fitness hack guide.

I’m a big believer in the advantages of making forgiveness a daily practice. If we hold on to stuff that makes us angry, we only fuel negative thoughts, which in turn leads to emotional and even physical problems. Sometimes, forgiveness is easier said than done. Fortunately there are plenty of people out there who have tried to make it practical for daily life—my favorite being author and speaker Gabrielle Bernstein.

Instead of driving everywhere, try walking, biking, or taking public transit. This is one of my favorite fitness hacks because it forces you to get off your behind and move. If you live two blocks from the pharmacy or the grocery store, try walking there. If you can make it happen, take the bus, subway or train to work, and if you can walk or bike to the gym, even better!

Health isn’t just about the physical body—it involves your mind and soul as well. By taking small actions to keep your overall health, in check you’ll soon find yourself taking on bigger initiatives to make your healthy lifestyle really stick.

Here’s to a happy and healthy 2013 and beyond!

How to Make Health Insurance a Bad Bet

I’m a self-employed business owner, which means I need to buy my own health insurance — and even a high-deductible plan would end up costing me thousands of dollars a year for my family, which is a waste since my family uses almost zero medical services.

And that’s the rub: for people who are healthy and who must pay for their own insurance, health insurance is a bad bet.

That’s according to my friend Tynan, a former professional gambler. If you’re healthy, your odds of using more than your high deductible in medical services (say, a $10,000 deductible) are very low. You are highly unlikely to ever use that insurance. And so you are, in effect, throwing your money away on a bad bet that you might someday use it, even if that’s an unlikely event.

Now, don’t get me wrong: for many people, health insurance is a good bet. If you have health problems, or have a condition (obesity, tobacco use, etc.) that is likely to lead you to health problems, you should definitely have insurance. If your employer pays for 80% of it, then health insurance is probably a good option no matter what. If you can’t afford to pay for routine doctor visits and preventative care, and couldn’t cover costs yourself if you got into an accident, you should probably get insurance.

But if you pay for your own insurance, and you do the things that lower your odds of using expensive medical insurance (more than a broken leg or a routine doctor’s visit), and can afford to pay for things yourself, then it’s a bad bet.

Update: I’ve gotten a lot of negative feedback on this post. I’m OK with that, as I don’t expect everyone to agree with me and actually appreciate opposing viewpoints. It’s caused me to reconsider my recommendations in this post, so I’ll clarify my position here: I don’t recommend that most people forgo health insurance. This is what I believe is best for me and my family, and I offer this post as an alternative to the mainstream view. I hope you’ll give these ideas some thought, but don’t make decisions based on one person’s example. These issues are too important to just go with what I’m doing.

So here are the two questions to answer in this post:

How bad a bet is it?How do you lower your odds of needing insurance, so that it becomes a bad bet?And what do I do if I ever lose that costly bet, and need a ton of health services?

Let’s answer these questions one at a time.

Just the summary: This is a really long post, but you can skip to the conclusion at the bottom if you just care about the actionable steps.

The chances of most people dying of a heart attack are about 1 in 5. But for me, because of my diet, exercise, age, blood pressure and cholesterol levels, etc. … it’s less than 1 in 100. Think about that: if you bet on a roulette table with 1 in 5 odds, you might actually make that bet. But you’d be a sucker to bet on a 1 in 100 odds bet.

That’s for dying of heart attack, not being hospitalized for one, and there are plenty of other ways to be hospitalized. But it is an illustration of how being healthy dramatically changes the odds.

Let’s take a look at the most common expensive medical conditions:

HIV $25,000Cancer $49,000Transplant $51,00Stroke $61,000 5 Hemophilia $62,000Heart Attack including Cardiac Revascularization (Angioplasty with or without Stent) $72,000Coronary Artery Disease $75,000Neonate (premature baby) with extreme problems $101,000End-Stage Renal Disease $173,000Respiratory Failure on Ventilator $314,000

I can cross out HIV (no shared needles or unsafe sex), hemophilia (a genetic disorder), and a premature baby (Eva & I are done with babies). Heart attack and coronary artery disease are pretty much the same thing. End-stage renal disease is from kidney failure, usually from Diabetes Mellitus or long-term, uncontrolled hypertension (high blood pressure). Respiratory failure on ventilator is what happens after a long bout in the hospital with a serious illness, but it could be a variety of serious diseases.

Transplants are usually kidney or liver. Liver failure can be from many things, including long-term heavy alcohol use, viruses spread through unsafe sex and sharing drug needles, or other conditions such as diabetes, heart disease or obesity. Kidney failure is pretty much the same as end-stage renal disease, so again, diabetes and uncontrolled hypertension.

There’s also auto accidents and things requiring long-term care (usually Alzheimers & dementia, strokes or old-age-related frailty).

So that leaves us with the most likely expensive medical conditions:

CancerHeart diseaseDiabetesHypertensionStrokeHIV or something else caused by needles/sexLiver failureAuto accidentAlzheimers & dementiaFrailty

To figure out what your odds of getting these conditions is almost impossible, I’ve found. There just doesn’t seem to be any chart that will tell you your odds of getting a condition depending on what risk factors you have. But you can reduce or eliminate risk factors — stop smoking, eat healthier, exercise, don’t drink too much — and your odds of getting a condition goes way down.

The heart attack illustrates this — dropping risk factors such as cholesterol, blood pressure, weight, age, smoking reduced my odds from 1 in 5 to less than 1 in 100. That’s a dramatic difference in odds.

The same thing happens for other cases — if you don’t drive, for example, your odds of getting killed in an accident drops from 1 in 100 to about 1 in 700 for a pedestrian accident. If you smoke, your odds are 15-30 times greater of getting lung cancer or dying from lung cancer than if you don’t smoke, and actually smoking increases your odds of most cancers and major diseases such as heart disease and stroke. If you don’t smoke, don’t have high blood pressure, aren’t overweight, and eat healthy and exercise, your odds of getting a stroke go way down.

So the odds aren’t really something we can calculate with certainty, but we do know that by eliminating the major risk factors, our odds go down by a factor of 7-30 or so. Instead of having a 20% chance, we have a 1% chance or less (by best estimation).

That’s a bad bet. It’s not a good idea to bet on something that has less than 1% chance of happening, especially to bet thousands of dollars on it. You can bet a few dollars on the lottery that you’re willing to throw away (better not to, but OK), but why would you throw away thousands of dollars on this low-odds bet?

The only reason: fear. You’re afraid of the worst happening (even if it’s very unlikely), so you take the safe (but bad) bet. We’ll talk about how to address this fear below.

My family has used almost zero dollars in medical care in the last 5 years, since we started becoming healthy. We used to use a lot in doctor’s visits, emergency room visits, asthma breathing machine treatments, medicine, and more. That’s all gone. Now we just need vaccinations and some minor check-ups to make sure everything’s OK.

What you’re really throwing away: For my family, a high-deductible insurance policy can cost $4,000-5,000 a year (about $350-400 a month). For a smaller family, it would be less. A lower-deductible insurance policy costs a lot more. Assuming a monthly payment of $380 and an annual return rate of 8%, if you invest that instead of spend it on insurance, you’d have $250,000 in 20 years. More, if you adjust the payments upward for inflation. That’s a big amount to gamble on something where you have less than 1% chance of using.

Note on Obamacare mandate: The worst part of Obamacare (which I’m generally in favor of) for me is the individual mandate to have health insurance coverage. If you don’t (starting in 2014), you could pay something like $2,500 in fines for a family like mine. That forces me either to take this bad bet, or take a penalty for being healthy. I understand why this might arguably be a good policy for the nation in general, but for me it’s horrible. I’m thinking of forming my own super-healthy insurance cooperative by 2014.

If we take a look at the major conditions that lead to expensive health care, above, we can take a look at the controllable risk factors, and then eliminate them. Note that there are risk factors out of our control — mostly genetics and race.

So first, let’s take a look at the Causes & Risk Factors, from the Center for Disease Control … note that for many conditions, there are other conditions that are risk factors — diabetes, cholesterol and high blood pressure are risk factors for heart disease and heart attack, for example. So we have to take a look at the risk factors for those conditions as well, and those are listed here:

Heart attack – bad blood cholesterol levels, high blood pressure, Diabetes Mellitus, tobacco use, diet high in saturated fat & cholesterol & sodium, physical inactivity, obesity, high alcohol useCoronary artery disease (CAD, or heart disease) – same as heart attackStroke – high blood pressure, high blood cholesterol, heart disease, diabetes, being overweight & obese, tobacco use, too much alcoholEnd Stage Renal Failure – usually from Diabetes Mellitus or long-standing, uncontrolled hypertensionDiabetes Mellitus – overweight/obese, genetics/race, high blood pressure (140/90 or higher), cholesterol with HDL (“good”) cholesterol is 35 or lower, or triglyceride level is 250 or higher, physical inactivityHypertension/High blood pressure – diabetes, diet high in sodium, not eating enough potassium, being overweight, physical inactivity, smoking, drinking too much alcoholBad blood cholesterol levels – age (rises with age), having diabetes, diet high in saturated fats, trans fatty acids (trans fats), dietary cholesterol, or triglycerides, being overweight, physical inactivityCancer – tobacco use, too much alcohol, excessive exposure to UV rays from sun/tanning beds, unhealthy diet, being overweight, physical inactivityHIV – unprotected sex, sharing needlesAuto accident: being obese (read more), being a young driver (16-24 – read more), smoking marijuana (read more), distracted driver, fatigued driver, drunk driving, speeding, aggressive driving, bad weather conditions, driving at night (read more for leading causes)

Summary – non-condition risk factors: These are the risk factors that we can control:

tobacco usebeing overweight/obesephysical inactivitydiet high in saturated fat & cholesteroldiet high in sodiumtoo much alcoholtoo much exposure to sununprotected sex/sharing needlesdriving safely or at all

So how do you lower your odds? By eliminating the risk factors that you can control. We’ll talk about that in the conclusion.

There are a couple long-term care conditions, such as Alzheimers, dementia, and frailty, that aren’t mentioned here. We’ll address those separately in the conclusion as well.

Does dramatically lowering your odds mean you’ll never get sick or injured? No, of course not. Even if you did everything perfectly, you could still get hospitalized. People who seem perfectly healthy from doing all these things get heart attacks — they just get them far less often.

And yes, eventually you’ll get something. As you get into your 50s, your odds go up, and into your 60s, they go up a lot. Most people who have heart attacks or cancer are in their 60s or older. Same thing for frailty, Alzheimers, hip fractures, etc. As you get older, it gets very likely you’ll need expensive health insurance. But I’m 39, and my family is younger than that, so we’re not in serious danger at the moment.

So if we can dramatically lower our odds by eliminating the main risk factors, why would anyone get health insurance? If you’re perfectly healthy and likely to stay that way for awhile, then the answer is simple: fear.

Fear is the motivator for insurance. And it’s not a rational motivation. What’s a more rational approach? Well, what if we looked at this unlikely worst-case scenario, and thought of other possibilities?

I could raise funds by creating a powerful product and asking all of you for help. I don’t like asking for help, but it’s not likely I’ll have to do this.I could sell Zen Habits. I wouldn’t like to do that, as I truly love this blog and its wonderful readers, but honestly, there is almost nothing in this world that I couldn’t let go of if I had to.I could go broke, and start again anew. I’ve done it before, and it’s not that bad. My family wouldn’t really suffer, as we always have other family and friends to stay with temporarily if we really needed it.

These aren’t the best, but they’re also not life-and-death. When you take the irrationality out of the decision-making process, you can see that the worst isn’t that horrible. And the worst is very unlikely.

There is the case of needing medical care that might cost a few hundred dollars, or even a few thousand dollars — if you don’t have insurance, what do you do? Well, we self-insure — meaning, we just pay for these expenses. We don’t have a lot of them at all (basically nothing in the last five years), but we have saved a lot of money from not having insurance, so we put that in the bank (and invest it). This kind of savings/investment plan is important, because if you just use the money you would have spent on health insurance on shopping or other kinds of expenses, then you’ll have nothing saved up for when you need to go to the doctor.

So what if you get into a bad accident or get some unexpected disease? Isn’t this invitation for bankruptcy? Well, how often has this happened to you? In my 39 years, it’s never happened, and most people I know haven’t faced this either. Again, let’s use rational arguments instead of fear.

So, for those who skipped to the end, let’s take the controllable risk factors, and eliminate them by doing these steps (please note that this isn’t medical advice, as I’m just a writer not a doctor, but it’s based on research from the CDC, Mayo Clinic, American Cancer Society and others):

Don’t smoke (read my quit guide, written nearly 6 years ago)Don’t be overweight (healthy BMI, waist measurement of less than 35 inches in women and less than 40 inches in men)Eat healthy (plant-based diet, lots of fiber, not a lot of red meat, saturated fat or animal fat)Exercise (at least 30 mins daily)Don’t drink too much alcohol (limit to 1-2 glasses for women, 2-3 glasses for men)Keep your blood pressure at a good level (eat healthy, low sodium, no smoking, exercise, limited alcohol)Keep your cholesterol numbers good (total cholesterol below 200 mg/dL, HDL or good cholesterol 60 mg/dL and above, triglycerides below 150 mg/dL)safe sex and don’t share needles (HIV, some cancers)avoid things that could irritate your lungs, like dust and strong fumes, and secondary cigarette smokeregular screenings for cancer, blood pressure, cholesterol, etc.drive safely or not at all (go at speed limit or below, don’t drink & drive or smoke marijuana, don’t be distracted or too tired, try not to drive at night, drive cautiously and not aggressively)Alzheimers & dementia – decrease odds through regular exercise, low-fat diet, healthy weight, active brain that learns new things (languages, dancing, etc.), staying involved in community.Frailty – stave off frailty through aerobic and also weight-bearing exercise, and exercises that improve balance — walking, yoga, tai chi, pilates.

And since some of those (blood pressure, cholesterol, Alzheimers, etc.) have the same recommendations as what’s already recommended elsewhere on the list, let’s boil it down:

Don’t smokeEat healthy – plant-based diet, low in saturated and animal fat, lots of fiberExercise regularly (aerobic & weight-bearing exercises)Keep yourself at a healthy weight by eating healthy and exercisingDon’t drink too muchHave safe sex and don’t share needlesDrive safely or not at all (my family is car-free)Have regular screenings for cancer, blood cholesterol and blood pressure

Our family does all of these things, and so for us, health insurance is a bad bet. And aside from the insurance question, we enjoy a healthy life and love feeling good, being active, eating delicious plant food, and walking instead of driving.

Eva & I enjoy 1-2 glasses of red wine at night, though the kids weirdly don’t have a taste for it. I guess some things are just inexplicable.

In addition: You should also build up savings/investment of at least a few thousand, and much more if you can, for unexpected medical needs. And finally, figure out a rational worst-case scenario plan.

If you need help with the eating and fitness habits, as I noted last week, I’m launching a new course with a group of great experts called Simple Fitness Habit. It should be out mid-week — I’ll let you know!

‘What’s Killing Us’ – TED ebook examines our toughest global health problems

In the past decade, we’ve changed the way we collectively view the health of the 7 billion people who occupy this planet. Health issues were once seen as an isolated national or regional problem; now they are a global concern. In What’s Killing Us: A Practical Guide to Understanding Our Biggest Global Health Problems, 2011 TED Senior Fellow and healthcare expert Alanna Shaikh lays out the most important challenges and issues in global wellness – from tuberculosis and HIV/AIDS to flu, maternal mortality, and the diminishing effectiveness of antibiotics – while untangling the web of jargon that so often permeate those discussions. Shaikh, who runs the international development focused-blog Blood and Milk, also provides clear ideas about how these worldwide problems can be managed.

In What’s Killing Us, you concentrate on 10 major health topics. Why just 10?

Because they cover a wide and varied range of health issues. Understanding them will give you the background you need to learn about any global health topic. These are some of the most important issues that the human race is facing, although they’re just the highlights of the many health threats that endanger us.

What are the most promising initiatives you’ve seen to improve global health?

Although it has taken some criticism lately,  The Global Fund to Fight AIDS, Tuberculosis and Malaria has elevated global health to a consistent international priority. I am also excited about inviting more people into health care – training community health workers, giving nurses more responsibility, and teaching people to care for their own health. Making good health is everyone’s job, not just the job of physicians. Our new focus on improving health systems is also inspiring. Looking at health and health care in a broader social and national context makes a huge difference.

How real are the threats of a global pandemic?

Our globalized lifestyles mean that there is almost no way to stop infectious diseases from spreading rapidly and internationally. When a very contagious disease crops up, we’re all at risk. We got off easy with swine flu because it was highly contagious but was not all that dangerous once you had it. There is no guarantee the next pandemic will be as benign.

We see a number of philanthropists, Bill Gates among them, devoting a lot of time and cash to improving health. How important are these actions?

Tremendously important. Global health is a field where targeted international effort and investment has a powerful impact on human lives. Many global health problems are things we know how to solve if we just had the funding to do it.

What are the health issues that we should worry about the most in the next five to 10 years?

The two biggest are climate change and tuberculosis. Drug-resistant tuberculosis is the big one. Tuberculosis (TB) is evolving so that our current drugs can’t treat it. TB is also contagious through the air so it spreads in situations like crowded cities and public transport. And climate change will be the biggest single threat to human health, causing everything from famine to natural disasters to new infectious diseases. We should also worry about the growth of non-communicable diseases like cancer, diabetes, and heart disease. Rates of these diseases are rising rapidly. Finally, as the planet urbanizes we need to start make making good, deliberate choices about the design of cities. If cities just grow without any government thought about the health of people in them, it will be a health catastrophe.

What’s Killing Us: A Practical Guide to Understanding Our Biggest Global Health Problems is part of the TED Books series. They are $2.99 and are available for the Kindle and Nook, as well as for sale on Apple’s iBookstore.

How to Be Healthy and Lose Fat: The 3 Minute HIT Health Hack That Helps Burn Fat


There’s new research out that suggests that you can make significant and measurable changes to your fitness. This research has uncovered how to be healthy without having to spend large amounts of time exercising…in just 3 minutes a week.

Yes…just 3 minutes of exercise a week!

To achieve this, it requires you to do High Intensity Training (HIT). In longer, more regular bursts, it can also be used to burn fat too. Science shows that low intensity, long repetition exercise is much more efficient at burning fat. However, for many people it’s a time-sink — it uses up far too much time.

Using HIT can help you burn more absolute amounts of fat in a shorter amount of time and you can improve your insulin sensitivity. It’s a great way for everyone to be healthy.

How does it work?

When you perform high intensity exercise, you use a lot more of your body’s muscles; around 80% of your body’s muscles are active.It moves sugar from blood into the muscle so that it can be readily burned.It releases adrenaline which acts as an appetite suppressant.You can release hormones that break down fat.High intensity exercise causes microscopic tears in your muscles as it strengthens. This healing uses up calories.Insulin regulation occurs due to release of growth factors such as IGF-1.Metabolic rate increases, which means you will burn more calories when resting.

How do you do it?

There are several exercises that can be done to do this. Here’s just one example that you can follow:

The Exercise Bike

And that’s it.

Okay, so this is basically 6 minutes of gentle exercise and 1.5 minutes of HIT, but you can adjust it to suit your needs. The HIT part of the exercise should not last longer than 30 seconds for each time. Do this once a week to help keep insulin levels healthier. If you want to burn fat, you want to be doing this a bit more regularly (like 2-3 times a week).

“HIT is really good at improving glucose uptake into the muscles in a very, very short time,” Professor James Timmons, leading the research at Birmingham, said. “With really intense exercise, you release hormones that can help break down fat. This may help burn that fat over time, after HIT is done.”

Teen sex hamsters in health danger shock alert

The Daily Mail is a UK newspaper famous for a moralising obsession with teen sex and a tragic, long-term science impairment.

Most of their science stories are simply face-palm material but occasionally they produce unintentional works of comic genius.

Today, is one of those days.

Teenage sex ‘leads to bad moods’ in later life’

Having sex during teenage years could lead to bad moods, changes in brain development and smaller reproductive tissues, according to scientists.

Researchers from Ohio State University College of Medicine found that these changes can occur because the sexual experience is taking place while the brain is still developing.

Study co-author John Morris said: ‘Having a sexual experience during this time point, early in life, is not without consequence.’

The researchers based their conclusions after studying the behaviour of hamsters after they engaged in sexual activity.
