Even after you’ve shed major pounds, keeping the weight off can be a huge struggle. One reason? Your body constantly feels hungry, according to a new study from the American Physiological Society.
For the study, researchers had 40 obese volunteers — which was defined as having a body mass index greater than 40 — attend five three-week long weight loss sessions over the span of two years. During the sessions, the participants were coached through daily exercise and eating healthy.
