When people start to lose weight, they will think that the loss of weight is due to the consumption of body fat and does not affect the metabolism of the body. Actually, it is not. When people go on a diet, the body's first reaction is to get energy from the immediately available energy, which is stored in sugar, not fat. In other words, at the beginning of dieting, the weight loss is mainly due to the consumption of glycogen. Only when the body adapts to the prescribed diet can it begin to consume fat and muscle. People who don't exercise to lose weight consume muscle, not fat. It can be seen that people who lose weight through dieting and can persevere lose weight not only by fat, but also by sugar, water and muscle.
There are not only dieting, but also saving water in order to lose weight as soon as possible. After a long time, the body will cause electrolyte disorder due to dehydration, which is harmful to health. Moreover, the weight lost due to water loss is easy to pick up, and the result is equal to not losing weight.
And sedentary people, diet to lose weight? Then the body began to become weak. After the prescribed dietary period, fat resurfaces quickly, so in a very short time, fat people "resurface" one by one, and may even set a new weight record.
Not only that, when the body adapts to the state of dieting, it will improve the efficiency of energy utilization and reduce the metabolic rate, making it more difficult to lose weight again.
Although dieters may lose some weight in a short time, the effect of losing weight is often not lasting. Therefore, instead of dieting to lose weight, it is better to observe reasonable and healthy eating habits and exercise regularly all the year round.
Studies have shown that when eating too little, there are many dangers to women that cannot be ignored.
lose hair
Too thin people have insufficient supply of body fat and protein, so their hair frequently falls off and loses its luster. If you diet too much, your hair will lack sufficient nutrition, including iron intake, and your hair will turn yellow and dark, which will eventually lead to a lot of hair loss.
break
The incidence of hip fracture in thin women is higher than that in standard weight women 1 times. This is because the level of estrogen in the body is insufficient, which affects the combination of calcium and bone and cannot maintain normal bone density, so osteoporosis and fractures are prone to occur.
If a person who is not fat but has been dieting says, "I have fatty liver." I'm afraid most people will find this a bit incredible. In fact, it is entirely possible. When the human body is in a state of long-term hunger, the body can't get enough glucose, choline, protein and essential fatty acids, and can't synthesize lipoprotein, which will affect the lipid metabolism of the liver and lead to a large amount of fat deposition in the liver, thus forming fatty liver.
Unbalanced nutrient intake leads to insufficient intake of hematopoietic substances such as iron, folic acid and vitamin B 12. Because of eating less, the basal metabolic rate is lower than that of ordinary people, so the gastrointestinal movement is slow and the gastric acid secretion is less, which affects the absorption of nutrients.
gastroptosis
Long-term hunger leads to loss of appetite, flatulence and pain, which is probably a sign of gastroptosis.
Memory decline
The main motivation for brain work comes from fat, eating too little, insufficient fat intake and storage in the body, and insufficient nutrition in the body. This nutritional deficiency seriously damages brain cells, which will directly affect memory and make people forget more and more.
dysmenorrhea
Fat is involved in the transformation, metabolism and storage of sex hormones, which is closely related to reproductive function. Dieting to lose weight? Women who are excessively emaciated and have too little fat have their ovarian function affected, leading to menstrual disorder and even amenorrhea or infertility.
Without enough fat protection, the uterus is easy to sag from its normal position, even out of the vaginal opening, forming uterine prolapse.
Faced with the potential threats of many diseases, the majority of slimming women should pay attention to their own health, and don't ruin their health in pursuit of temporary beauty.
