No matter what people do, they should follow a kind of limitation. When people lose weight, they should also grasp the limitation. Men always laugh at women when women crazily lose weight. In fact, many men also try to reduce the weight through improper ways, such as the intake of low heat and the vegetarian diet. The improper ways can cause serious results in daily life. 

The inadequate intake of heat can cause sudden death. Many people try to decrease the weight by controlling the intake of heat during dinner. However, it is essential for people to absorb more than 600 calories of heat, or the health of heart can be threatened. If people always supplement inadequate heat, the sudden death can even be caused.

The rapid decline of the weight can induce biliary calculus. According to the medical research, many people will get biliary calculus if they lose weight in an excessively rapid speed. This is because the content of gall is extremely increased and crystals can be produced. At the same time, the secretion of gall can be restrained and the functions of gall bladder are weakened, which can not eliminate gall in time. Therefore, people should not blindly seek for slimness in a short time. In addition, the memory of the human body can also be affected during the process of losing weight. In order to protect the brain and keep healthy, people should decrease the weight carefully.

The single vegetarian diet can cause alopecia. According to the research in Japan, more and more cases of alopecia keep a close relationship with the vegetarian diet. The main components of hair are protein, zinc, iron, copper and some other trace elements. However, if men just eat fruits and vegetables in daily life, they can just supplement vitamins like vitamin E for their bodies. The protein and trace elements can not be supplemented adequately. Thus, the alopecia can be caused because of the serious malnutrition.

What’s more, the improper ways of losing weight can also cause the rebound of the weight, which can induce the heart disease. According to the research in America, 40% of men have been troubled by the rebound of weight, the heart disease and other chronic infectious diseases like hepatitis and tuberculosis. Therefore, it is necessary for people to lose weight and take exercises together so as to keep the weight stable and prevent possible harms.
