Why do you lose weight and rebound? Scientists first fed mice with a high-fat diet. After the mice became obese, some of them were given a normal diet, and they returned to their original body shape. The above feeding method was repeated several times. It was found that each time the mice on a high-fat-normal diet returned to their original weight, their oxygen consumption, energy expenditure, and other indicators of obesity returned to normal values, but their net weight gain was greater in each dieting cycle In mice that have always maintained a high-fat diet. What causes excess weight gain? Scientists have found that the circulation of high-fat and low-fat diets can change the balance of intestinal flora in mice, disrupting beneficial flavonoids, leading to Mice are more likely to gain weight. Which of the following, if true, cannot support the above conclusion:. ['Study finds that the flora of obese mice uses fewer flavonoids.', 'Human and mouse intestinal microbial communities, similar patterns in weight loss.', 'When flavonoid dietary supplements are used, they can suppress excessive rebound of body weight.', 'When mice return to normal drinking and lose weight, the broken flora in the body will not recover on its own.']
