What is dieting? For seven days, 2-3 hours must be set aside for exercise every day during dieting: 40 minutes for aerobic exercise, such as long-distance running, and 30 minutes for anaerobic exercise, such as stretching equipment. Problems such as sweating, dizziness and shortness of breath will occur during dieting. Pay special attention to nutrition in the late stage of dieting, otherwise it will rebound quickly. So can you lose weight by dieting? Of course, if you are so fat that you can't breathe when you walk, you just want to eat every day and don't want to move at all. What do you want to eat when you sit down? What do you want to eat when you lie down? You can only lose weight in an idiotic dream. Dieting means eating less than usual, not not not eating. If you eat it wrong, the consequences will be unimaginable. So what are the disadvantages of dieting? There are not only five kinds, but also many misunderstandings.
Misunderstanding 1: Go on a diet/eat together
Patient crisis: gastric cancer
The media once said that a 2 1 year-old girl had stomach cancer. Although it sounds strange, the culprit is repeated weight loss: in order to lose weight quickly, she once only ate bananas or even drank white water every day, and finally lost weight through the underworld. But she was always hungry, so she couldn't help overeating and began to fall into a vicious circle of dieting-overeating. After a while, her stomach finally went wrong. Yolanda, a 34-year-old foodie who died of stomach cancer a few years ago, summed up the reasons for personal physical damage: "I didn't take good care of my stomach, my diet was extremely irregular, I was so hungry that I often went on a diet to lose weight. With such repeated tossing, my stomach became the thinnest in my body. Dieting and revenge will come in 10 years.
Myth 2: Vomiting and strenuous exercise
Patient crisis: anorexia nervosa
Fennie Yuen, a Hong Kong artist, suffered from anorexia because of losing weight. She didn't eat or feel anything for several days, and her weight once dropped to 3 1kg. She once told the media that suffering from anorexia made her feel world-weary. Dr. Chen Jue from Shanghai Psychosomatic Medicine Department had a special discussion on 54 cases of anorexia. The results showed that 88.9% of anorexia nervosa patients were women, and "fear of obesity" ranked first, accounting for 77.8%. There are many ways for anorexia nervosa patients to lose weight, such as avoiding fattening food, excessive exercise, defecation and vomiting. The terrible thing about anorexia nervosa is that once you get this disease, even if you want to cure it, it is very difficult. Even if you want to lose weight, you should eat three meals, and properly control staple food and meat, step by step. Advocate that fruits and vegetables should not be reduced and milk should not be reduced. Milk has a high calcium content, which is very important for women. On a diet, you should reduce the quantity without reducing the quality.
Myth 3: Eat only apples for three meals.
Patient crisis: malnutrition
It is useful to eat only fruits, vegetables or bananas without meat and staple food, but it will be dangerous in the long run: because our body's energy mainly comes from fat, carbohydrates and protein, if we don't eat meat and staple food at all, protein, fat and carbohydrate will be seriously insufficient, and energy intake will be greatly reduced, thus greatly increasing the incidence of malnutrition, anemia and osteoporosis, thus affecting various functions of the body and damaging health. Diet pills will reduce the absorption of body fat, and also affect the absorption of various vitamins and fatty acids together, so it will also constitute a lack of nutrients. Poor resistance to weight fluctuations. In the mid-term of cancer research in the United States, a questionnaire survey was conducted on 100 overweight healthy women. Three quarters of them lose weight repeatedly, losing more than 4.5 kilograms each time. When testing their natural killer cells, it was found that the number of natural killer cells in the human body with the most weight recovery (more than 5 times) was the least, while the number of people with stable weight for several years was the most.
Myth 4: Eat only vegetarian food, not meat.
Patient crisis: osteoporosis
Orthopedics doctors often use "silent disease" as an example of "osteoporosis", because osteoporosis has no manifestations in the early stage. The professor believes that if young women lose weight too blindly, it will easily lead to osteoporosis in the future. Usually, the calcium content in vegetables and fruits is low, and more importantly, there is no fat at all, which will reduce the excretion of estrogen in the body, affect the connection between calcium and bone, and simply present osteoporosis. A study in the United States found that after dieting 18 months, although women lost 7 pounds, their bone density would also decrease. To prevent osteoporosis, first of all, calcium intake should be moderate and important, and eat more foods with high calcium content, such as milk, cheese, green leafy vegetables and soybeans. Secondly, we should also pay attention to removing dangerous elements such as drinking coffee and cola. Especially white-collar workers in the office, they should pay more attention to the sun and exercise 2-3 times a week.
Myth 5: Eat only meat, not meat.
Patient crisis: depression
Robert atkins, an American nutritionist, thinks that if you want to lose weight, you can't just refuse meat. On the contrary, you should eat more fat and protein and less carbohydrates. The Atkins diet is often called the meat diet. Eating only meat without eating can be more resistant to hunger and improve the body's innovative ability, but it will pose an excessive burden on the kidneys. This eating habit has now caused kidney disease in adults in Britain13. Eating meat to lose weight simply leads to an increase in blood lipid content, which is very unlucky for heart health. Excessive fat intake will also increase the probability of breast cancer in women. And a scientific study in Britain has come to another conclusion-eating meat to lose weight will bring depression. Meat is edible, and it is best to remove the skin when eating meat, which can reduce the intake of whole fat. Make sure to take multivitamins and enough calcium. These nutrients will not hinder weight loss. Drinking 2 liters of water a day can effectively improve the phenomenon of water shortage caused by eating too much meat and reduce fatigue and constipation. Eating more vegetables can also replenish water and nutrition for the body.
Myth 6: Always stick to vegetarian food on an empty stomach.
Patient crisis: anemia, hypoproteinemia
Vegetarians are indeed more prone to iron deficiency anemia! Although plant food can also supplement iron, its absorption is far less than heme iron in animal blood and red meat. The best food layout for weight loss is that carbohydrates are the main energy source, accounting for 40%-50% of the total calories, and protein should be enough to reduce fat. If the food layout is wrong, the calorie intake may be reduced, leading to malnutrition, anemia, hypoproteinemia and so on. , manifested as fatigue, dizziness, palpitation, simple lethargy, slow response, memory loss, severe fainting, and even affect breathing and heartbeat. Women of childbearing age should pay special attention to iron supplementation. Iron deficiency anemia in women of childbearing age is mostly due to the loss of more iron every month, which is a slow blood loss. If you don't pay attention, your skin will dull and shrink, and your hair will fall off easily. Advocate women not to be vegetarian or partial to food, eat more fish, eggs and lean meat, eat more fresh fruits and vegetables and supplement the intake of vitamin C, and avoid drinking strong tea, because polyphenols in tea can reduce the absorption of iron.
Myth 7: Eat staple food and take diet pills.
Patient crisis: heart disease
Eating less staple food will increase bad cholesterol and greatly increase the risk of heart disease. The researchers studied 320 obese people. One group did not eat staple food at all, while the other group consumed 55% of the total calories every day. After a few weeks, both groups lost 6 kilograms, but the bad cholesterol in the group that ate more staple foods decreased by 7 mg per liter, while the bad cholesterol in the group that did not eat staple foods increased by 65,438+02 mg per liter. In addition, taking diet pills will also increase the burden on the heart, because some irregular diet pills will be rich in inappropriate pharmaceutical ingredients, such as thyroxine, which will lead to heart disease. There are three points to protect the heart: (1) Eat fish twice a week. (2) Ensure 20 grams of dietary fiber every day. Dietary fiber can effectively reduce the content of bad cholesterol in human body, and the optimal intake is 15-30 grams per day. For example, eat whole wheat bread in the morning, drink miscellaneous grains porridge for dinner and eat more fruits and vegetables. (3) love soy products. Soybean products are rich in isoflavones, which are natural phytochemicals and help to eradicate bad cholesterol that damages arteries in the human body.
Myth 8. Don't eat breakfast and drink slimming tea.
Patient crisis: gallstones
Cholelithiasis is often closely related to eating too little, especially those who are eager to lose weight, do not eat breakfast, rice, and some even eat only a few vegetables. Because of too little food intake and too high cellulose content, the gallbladder will stagnate, the emptying will be delayed, the bile will be sticky and stones will be produced. Scientists have made a special discussion on patients with gallstones caused by weight loss. The results showed that the bile salt content of dieters increased obviously, the mucus increased by at least 10 times, and the calcium also increased by 40%. The addition of calcium and mucus plays a major role in the composition of gallstones.
If you don't eat breakfast and sit for a long time after meals, you will easily get gallstones.
People who skip breakfast are much more likely than those who eat breakfast on time. This is because skipping breakfast will reduce the cholic acid content in bile and make bile concentrated, which is beneficial to the formation of gallstones in gallbladder. People who prefer meat and sweets will consume more fat and cholesterol, which is easy to form gallstones; In addition, sedentary after meals also simply promotes the composition of gallstones.
