Hello, landlord. Dietary fiber itself can't lose weight, but it can promote the good digestion and excretion of solid waste. Appropriate cellulose supplementation can increase and soften the food in the intestine, promote intestinal peristalsis, thus speeding up defecation, preventing constipation and reducing the risk of intestinal cancer. Moreover, cellulose can also regulate blood sugar and help prevent diabetes. It can also reduce the absorption of fat during digestion and lower cholesterol levels. Since it can promote defecation and eliminate waste, the small belly will naturally flatten out, so this is to achieve the purpose of losing weight from the side. Dietary fiber not only has the function of losing weight, but also can promote defecation, and has the effect of detoxification and beauty.
