Repeated weight loss followed by weight regain, often called "yo-yo dieting" or weight cycling, has long been viewed as unhealthy and potentially even worse than staying overweight. However, a major new review published in The Lancet Diabetes & Endocrinology argues that this belief is not backed by strong scientific evidence. In an invited Personal View article, … [Read more...]
Scientists Reveal How Seven Days of Fasting Transforms The Human Body
Going without food for several days does far more than force the body to burn fat.

Scientists Find a Way to Stop Dangerous Belly Fat as we Age
As people get older, both the amount of fat in the body and where it is stored begin to shift. Most body fat is subcutaneous, meaning it sits just beneath the skin. This type of fat is generally not harmful and is actually necessary for overall health. Visceral fat is different. It builds up deep inside the abdomen and surrounds internal organs, and it has been strongly … [Read more...]
