In recent decades, people have blamed eating meat for the disease of wealth. When it comes to health care, people should first eat more whole grains and vegetables and fruits. On the human side, some people have gone from the extreme of big fish and big meat to the other extreme, vegan.

When we eat big fish and meat every day, eating some coarse grains and vegetarian food properly can certainly reduce the burden on the stomach and promote digestion and absorption, but if we are vegetarian every day, we should not advocate it.

The advantages of vegetarianism are less fat intake, less obesity and arteriosclerosis, and dietary fiber can also promote defecation, but long-term unscientific vegetarianism is not conducive to health, including weight loss. Because in vegetarian diet, except beans, which are rich in protein, the content of protein in other foods is very low, and the nutritional value is very low, which can't meet the daily demand of human body for high-quality protein. Long-term vegetarianism will lead to malnutrition, decreased resistance, susceptibility to diseases, osteoporosis, and even fractures and infertility due to protein and insufficient fat intake.

From the point of view of nutrition, it is reasonable to keep the ratio of meat and vegetables at around 7: 1.

Food intake and exercise are two main factors to maintain a healthy weight. Therefore, scientific weight loss should control calorie intake and ensure adequate exercise. Because lack of exercise is the direct cause of obesity, while staying up late and eating irregularly and unscientific are the indirect causes of obesity. Therefore, eating less does not mean that calories are low, and vegetarianism does not necessarily mean that you are not fat.
