We’ve all heard the pro- and anti-high fructose corn syrup arguments, but here’s a new explanation for why HFCS (which is seemingly no worse than regular sugar) could cause greater weight gain: It was shown to cause addiction-like reactions in lab rats.

Are you a commitment-phobe? …We don’t mean in your love life, we’re talking about your doctor. Research suggests patients who are overweight switch primary care physicians more often, which interrupts their medical care. Those who switch MD’s more often land themselves in the ER at a higher rate than those who don’t.

The fight against childhood obesity in the U.S. often centers on changes to the school system. We’re excited to finally see some good news here: One study suggests PE class could actually help reduce the obesity rate.

And how’s this for a headline, “Making Ice Cream More Nutritious With Meat Left-Overs.” Mmmmm. Would you eat meat-fortified ice cream?

Great news if you’re getting up there in years: 70 to 80-year-olds who participated in cardio or strength-training exercise programs had fewer health bills than those who didn’t, according to a recent study. All the more reason to adopt healthy exercise habits when you’re young!

If you’re overweight, you already know weight loss is hard. But recent research has explored why obesity in particular is so hard to overcome — and it has to do with the way the brain actually monitors food intake. The latest research reveals there could be a solution, though.

We were surprised to read that easy access to gyms (e.g. at work) can actually lower some people’s quality of life. While those who attended often reported an improved quality of life, those who attended very little reported a decreased quality of life. Researchers attributed the change to negative self-talk among the non-users. The lesson? If you miss a workout, don’t sweat it! We all make mistakes sometimes and it’s far more important to let yourself off the hook.

New regulations around the U.S. are requiring chain restaurants to post meals’ calorie content. Researchers are now suggesting regulations be expanded to cover smaller chains and independent restaurants at all. What do you think: Too much government oversight or all’s fair in the name of public health?

There’s always been debate as to whether the timing of your meals really affects how much fat you store, but one fact remains indisputable: When we eat late at night we almost always eat less healthy foods. A recent study aims to explain this from an evolutionary perspective.

You probably already know the Mediterranean diet is good for your waistline, but recent research suggests it could also enhance memory and brain function.

Anyone who’s overweight knows that it’s easy to gain weight but very, very difficult to shed it again. Scientists may now have an explanation. One study found there’s a significant cellular change in the brains of obese people, which makes it harder for the body to let go of excess weight.

And a study on green tea this week acts as an important reminder to take every study with a grain of salt. While green tea has been touted as the one-size-fits-all solution to obesity, diabetes, unhealthy lipid levels, and more, researchers showed that while there are some positive impacts from drinking green tea daily, it might not be everything it’s cracked up to be.
