The diet that helps you keep weight off
Make sure that calories taken in are equal to calories expended and you can maintain your current weight, right? It's a diet truth we've read and heard about for years now. Not so fast, say researchers who published new findings about the subject in The Journal of the American Medical Association last week.
Researchers studied participants who'd recently lost weight to see what kind of diet was most effective in helping them maintain their new weight. Maintaining weight is difficult, because your metabolism slows down after you lose weight. This means that new hot body you worked so hard to attain doesn't expend as many calories at rest as it used to. (I know. It's not fair).
The researchers studied the effect of three different diets on metabolism: the low-fat diet, the low-carb diet, and the low glycemic-index diet. The low-fat diet had the worst effect on metabolism. Participants on this diet also experienced lower levels of "good" cholesterol and increased fat, otherwise known as triglycerides. The low carb-diet boosted metabolism, but it also increased risk of developing heart disease. (This diet also causes bad breath and farting, doesn't it?) The low glycemic-index diet boosted metabolism more than the low-fat diet but less than the low-carb diet. It had no negative impact on health. The authors singled it out as the best diet to follow.
What is the low glycemic-index diet? It's a fancy term for the Mediterranean diet, one rich in fish, fruit, vegetables, nuts, whole grains, and "good" fats like olive oil and avocado. It delivers the tastiest meals, too.
