If you deliberately diet, your body will be in a state of low nutrition. Long-term chronic malnutrition will inevitably make the organ itself hungry for a long time and make the organ function abnormal.

Liver: The synthesis of serum protein decreased, and the level of circulating protein decreased.

Heart: Blood output and myocardial contractility decrease.

Lung: respiratory muscle weakness atrophy, decreased vital capacity and tidal volume, abnormal mucociliary cleaning function.

Stomach: Digestive function declines, because gastric acid is still secreted, and at this time, there is no food for the stomach to digest, and gastric acid will begin to self-stimulation, thus causing chronic gastritis, gastric ulcer and other diseases.

Kidney: the function declines, leading to general fatigue, listlessness, decreased libido, and a few people will also have edema of lower limbs to varying degrees.

Brain: because of dieting, it is also in a state of chronic malnutrition, and its nerve cells will be relatively ischemic and hypoxic. Therefore, memory will decline and thinking ability will also decline.

In addition, dieting can also cause nutritional diseases, such as protein's calorie malnutrition, ranging from weight loss to dry skin, sparse hair and edema all over the body, to weight loss.
