Myth 1: Go on a diet and eat a meal replacement bag.
Patient crisis: gastric cancer
The media once reported 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 after a hellish weight loss, but she was always hungry and couldn't help but overeat, and began to fall into a vicious circle of dieting and overeating. After a while, her stomach finally protested.
Yolanda, a 34-year-old gourmet who died of stomach cancer a few years ago, summed up the reasons for his 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. After repeated tossing, my stomach became the weakest organ in my body. "
Health reminder: Dieting and revenge will come in 10 years.
The study found that if you start dieting and lose weight at the age of 25, your health will be damaged after 10 years. Dieting makes only a little food reach the stomach, and the running ability and endurance of the stomach will gradually decline. At the same time, the stomach has to endure the torture of excessive gastric acid soaking. In the long run, the probability of suffering from stomach diseases will greatly increase.
Myth 2: induce vomiting, exercise vigorously and take diet pills.
Patient crisis: anorexia nervosa
Fennie Yuen, a Hong Kong artist, suffered from anorexia because of losing weight. She hasn't eaten for days and doesn't feel anything. 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 the Department of Psychosomatic Medicine of Shanghai Mental Health Center, conducted a special study on 54 cases of anorexia. It was found 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 food that leads to obesity, excessive exercise, defecation and vomiting. The terrible thing about anorexia nervosa is that once you get this disease, it is very difficult to cure it yourself.
Health reminder: go on a diet, reduce quantity without reducing quality.
Even if you want to lose weight, you should eat three meals, properly control staple food and meat, and step by step. It is suggested 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.
Myth 3: Eat only apples for three meals.
Patient crisis: malnutrition
Eating only fruits, vegetables or bananas without meat and staple food is effective, but there are many dangers 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 can reduce the absorption of body fat, but also affect the absorption of various vitamins and fatty acids, and also lead to the lack of nutrients.
Health reminder: weight fluctuation and poor resistance.
The American Cancer Research Center has conducted a questionnaire survey on more than 100 overweight healthy women, and 3/4 of them have repeatedly lost weight, each time losing more than 4.5 kilograms. 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 natural killer cells in the human body with a constant weight for several years was the most.
Myth 4: Vegetarian, no meat.
Patient crisis: osteoporosis
Orthopedics doctors often use "silent disease" as a metaphor for "osteoporosis" because osteoporosis has no symptoms in its early stage. Experts believe that if young women lose weight too blindly, it will easily lead to osteoporosis in the future. Generally, vegetables and fruits contain less calcium, and more importantly, almost no fat, which will lead to the decrease of estrogen secretion in the body, affect the combination of calcium and bone, and easily lead to osteoporosis. A study in the United States found that after dieting 18 months, women lost 7 pounds, but their bone density also decreased.
Health reminder: The sooner you prevent osteoporosis, the better.
To prevent osteoporosis, calcium intake is very important first. Eat more foods with high calcium content, such as milk, cheese, green leafy vegetables and soybeans. Secondly, we should also pay attention to removing the risk factors such as drinking coffee and cola. Especially office white-collar workers, they should pay more attention to basking in the sun and exercise 2-3 times a week.
Myth # 5: Eat only meat without eating.
Patient crisis: depression
Robert atkins, an American nutritionist, believes that people can't lose weight by blindly rejecting meat, but 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 tolerant of hunger and improve the metabolism of the body, but it will cause excessive burden on the kidneys. This eating habit has led to kidney disease in adults in Britain13. Eating meat to lose weight is also easy to cause an increase in blood lipid content, which is very unfavorable to 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.
Health reminder: suggest "new meat diet"
Meat is edible, and it is best to remove the skin when eating meat, which can reduce the intake of saturated fat. Be sure to take multivitamins and enough calcium, which will not hinder weight loss. Drinking 2 liters of water a day can effectively improve the water shortage caused by eating too much meat and relieve 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 and utilization efficiency is far less than heme iron in animal blood and red meat. The best food structure to lose weight is that carbohydrate is the main energy source, accounting for 40%-50% of the total calories, fat is reduced, and protein should be sufficient. If the food structure is wrong, or the calorie intake is reduced, it may lead to malnutrition, anemia, hypoproteinemia and so on. , manifested as fatigue, dizziness, palpitation, lethargy, slow response, memory loss, even syncope, and even affect breathing and heartbeat.
Health reminder: women of childbearing age should pay special attention to iron supplementation.
Iron deficiency anemia in women of childbearing age is mostly caused by menorrhagia and iron loss, which is a chronic blood loss. If we don't pay attention, the skin may dry and shrink, and the hair will fall off easily. It is suggested that women should not be vegetarian or partial eclipse, eat more fish, eggs and lean meat, eat more fresh vegetables and fruits to increase the intake of vitamin C, and avoid drinking strong tea, because polyphenols in tea will reduce the absorption of iron.
Myth 7: Don't eat staple food, eat diet pills.
Patient crisis: heart disease
Eating less staple food will lead to an increase in bad cholesterol and greatly increase the risk of heart disease. The researchers studied 320 obese people. One group ate almost no staple food, 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 increase the burden on the heart, because some irregular diet pills may contain improper pharmaceutical ingredients, such as thyroxine, which will cause heart disease.
Health reminder: You should do the following three things to care for your heart.
1, eat fish twice a week. When the frequency of eating fish reaches one week 1 time, or even one day 1 time, the probability of heart attack can be greatly reduced. Fish here refers to tuna, mackerel, salmon and sardines rich in omega-3 fatty acids.
2. Ensure 20 grams of dietary fiber every day. Dietary fiber can effectively reduce the content of bad cholesterol in human body, and it is best to take 15-30 grams every day, such as eating whole wheat bread in the morning, drinking miscellaneous grains porridge at dinner and eating more fruits and vegetables.
3. Prefer soy products. Bean products contain a natural phytochemical isoflavone, which helps to remove harmful cholesterol that harms arteries in the human body.
Myth 8. Don't eat breakfast and drink slimming tea.
Patient crisis: gallstones
Gallstones are 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 small amount of vegetables. Because eating too little and the cellulose content is too high, it will cause gallbladder stagnation, delayed emptying, sticky bile and even stones. Scientists have made a special study 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 increase of calcium and mucus plays a major role in the formation of gallstones.
Health reminder: skipping breakfast and sitting for a long time after meals are prone to gallstones.
People who don't eat breakfast are much more likely to suffer from gallstones than those who eat breakfast on time, because skipping breakfast will reduce the content of cholic acid in bile and concentrate bile, which is conducive to the formation of gallstones in gallbladder; People who prefer meat and sweets are also prone to gallstones due to excessive intake of fat and cholesterol; In addition, sedentary after a meal is also easy to promote the formation of gallstones.
