The temperature rises in summer, and people easily sweat, so summer is the best time to lose weight. In addition, it is very hot in summer, so we usually wear thin clothes, and only a slim figure can show our personal charm. People lose weight in different ways. Some people exercise to lose weight, some people take diet pills, and of course many people lose weight by dieting. In fact, the best way to lose weight is exercise, which is very harmful.

1, the disadvantages of blindly dieting to lose weight

Summer is the peak time for women to lose weight. In order to put on beautiful clothes and show off their beautiful figure, female friends have tried every means, among which dieting is one of the most widely used methods. But blindly dieting to lose weight is easy to cause amenorrhea.

Pituitary gland is the most complex endocrine gland in the body. The hormones produced are not only related to the growth of bones and soft tissues, but also affect the activity of endocrine glands. It secretes a variety of hormones, such as growth hormone, thyroid stimulating hormone, adrenocorticotropic hormone, gonadotropin, oxytocin, prolactin, melanocyte stimulating hormone and so on. It can also store antidiuretic hormone secreted by hypothalamus. These hormones play an important role in metabolism, growth, development and reproduction.

Nowadays, many women blindly pursue slimness and often use dieting to lose weight. I don't know that long-term malnutrition will reduce pituitary function and can't secrete enough gonadotropin. It leads to atrophy of reproductive organs such as ovaries, decreased function and primary amenorrhea. Some women who have been dieting excessively for a long time will have amenorrhea for a year or two even if they resume eating and gain weight. This is because long-term hunger has damaged pituitary function and can't restore normal secretion function in a short time.

2. Diet principle of losing weight

1, pay attention to the collocation of main and auxiliary foods.

Many people tend to pay more attention to energy control in the process of losing weight, and usually reduce the intake of starchy foods such as rice. In fact, insufficient rice intake leads to hunger, but it is more vulnerable to the temptation of snacks, leading to excessive energy intake. Losing weight is not to say "don't eat", but to pay attention to the reasonable collocation of staple food, side dishes and soup. A balanced diet is the cornerstone of losing weight.

2. Eat slowly.

Chewing more than a few times when eating is not only beneficial to the digestion of food by saliva and gastric juice, but also beneficial to reducing eating. When food enters the human body and blood sugar rises to a certain extent, the appetite center of the brain will send a signal to stop eating. If you eat too fast, you will overeat before your brain signals you to stop eating.

Breakfast is big, lunch and dinner are small.

Contrary to the traditional diet, the ratio of breakfast, lunch and dinner should be large, medium and small, because the energy consumed at night is usually less, so you must not eat more.

Step 4 eat more green vegetables

Vegetables are low in calories and high in dietary fiber. Eating half a catty of green leafy vegetables cooked with little oil in one meal can effectively increase satiety, delay the emptying speed of food in the stomach and help control food intake.

5, less oil, less salt and less sugar

Whether you go out or cook at home, you should try to be less oily, less salty and less sugar. High-salt food is not conducive to weight loss, because a large number of sodium ions are gathered in the body, which will cause water and sodium retention and obesity. Eating too much greasy food can also lead to excessive calorie intake. Sweets are generally high in calories and cannot be eaten.
