As the simplest and healthiest way to lose weight in diet, fruit is increasingly loved by dieters. Fruit is a kind of food that cannot be separated from daily life. In addition to vitamins and sugars, fruits are also rich in dietary fiber, which can play a role in losing weight through reasonable consumption. Dietary fiber in fruit absorbs water in the large intestine after chewing, forming a gelatinous substance, similar to a sponge. It can wrap cholesterol and cholesterol-like substances and excrete them from feces. Bile is synthesized in the liver and its raw material comes from cholesterol. When cholesterol is continuously lost from feces, the liver will inevitably extract cholesterol from blood as a raw material to synthesize new bile for digestive function. This is used and excreted, thus lowering the blood cholesterol level. So sometimes using the gelatinous substance in fruit to lose weight will have unexpected weight loss effect. Apples, oranges, kiwis, bananas, tomatoes, pineapples and so on. Both have weight loss effects.
