Not everyone can gain weight! Because the factors influencing obesity are: 1 heredity, 2 central nervous system, 3 endocrine system, 4 metabolic factors and 5 others, such as nutritious diet. Weight is like a bank deposit. When you can't eat more calories than you need, you can't keep your weight. Of course, there are many reasons for not being fat. Physiological factors include: diseases, gastrointestinal function, drugs, psychological factors, such as anxiety, tension, depression, and bad eating and living habits. Physiologically, the nutritionist suggests that you consult a doctor, and the problem of eating enough needs the nutritionist to help you evaluate. There are several methods that you can use as a reference when eating and taking nutrition choices: 1. A balanced diet can use high-fat and high-sugar foods such as cream or other edible oil, jam and sugar to increase calories. Although weight gain is relatively rapid, long-term or excessive consumption will destroy appetite, and may bring chronic diseases and endanger health. Take a balanced diet, gradually increase the amount of food, avoid compulsive supply and destroy appetite. 2. Develop good eating habits, regularly quantify, eat a small amount and eat slowly. 3. Change the dining procedure. Eat foods with high concentration and high nutritional density before eating other foods. 4. Choose moderately cooked food. Choose moderately cooked food, such as steaming, stewing, marinating, frying and boiling. Avoid food hardening and indigestion due to frying, frying and baking. 5. Keep a happy mood, arrange the dining environment and concentrate on eating. Tension and anxiety not only affect appetite, but also the digestive and absorption function of gastrointestinal tract is not good, and the improvement of metabolic rate consumes relatively more calories. If you still can't improve your tall and thin figure, I suggest you find a professional doctor to help you find out the reason why meat can't grow, and grow healthy meat in a healthy way! There is another food that will make you fat-first place: eat 6 chocolate biscuits every day, the calorie is 302cal, and you gain weight 14 kg a year. Do you feel hungry while drinking tea? Have a chocolate biscuit. Although the diet books all say that celery and carrot sticks should be used instead of snacks, these fruits and vegetables are healthy but tasteless, so take some favorite chocolate biscuits to satisfy your hunger. But do you know what's in chocolate biscuits? The answer is: lots of sugar and lots of fat. If you satisfy your craving with chocolate biscuits every afternoon, you will gain 7 kilograms in just half a year. If this continues for a year, 14 kg of meat will move with you. Behind the delicious food is a trap of high calorie waiting for you. Foods with high oil and sugar will make people aging rapidly. Suggestion: To obtain antioxidant effect, it is better to drink more low-calorie green tea than to obtain polyphenols from chocolate. Second place: eat a chocolate bar every day, the calorie is about 280cal, and gain weight 13 kg a year. If you don't have time for dinner, shall I give you some snacks to satisfy your hunger? If you really fill your hunger with chocolate bars, don't make up for another dinner afterwards. Because a chocolate bar has half the calories of a dinner. If you can't live without the delicious chocolate, caramel and peanuts, then I suggest you keep an eye on the numbers in weighing scale. Eating such high-calorie snacks every day is neither fat nor difficult. In addition, the high sugar content in chocolate bars is an accomplice to oxidation, which will also accelerate your aging. Suggestion: If you can't give up the habit of eating a piece of chocolate every day, you'd better find time to jog for half an hour every day to balance the calories of that small piece of chocolate. Third place: drink 500ml canned fruit juice every day, with 255cal calories, and gain weight 12 kg a year. I know that vegetables and fruits are rich in vitamins and minerals, but I'm too lazy to eat fruits. Since we didn't eat fruit, let's use juice instead. However, replacing fruit with fruit juice can't get enough minerals and vitamins, because many minerals and vitamins have been lost in the process of making fruit juice. The only remaining vitamin C will also be reduced by light. If you look carefully at the label on the canned fruit juice, you can find that most of the fruit juice is concentrated and reduced, with a lot of sugar added. So, if you think drinking fruit juice is more nutritious, come to a can every day. The high sugar in fruit juice will make you gain weight 12kg after one year. Suggestion: In order to keep healthy, eating more fresh fruits and vegetables is definitely the only way to keep slim. Fourth place: Ordinary cola drinks a can of 375ml a day, with calories 168cal. Gaining 8 Jin a year is the most common drink for everyone. Of course, when you eat hamburger fries, you should have coke with it. And when we get together to share delicious pizza, we also use coke to match the taste of pizza. However, even without food, many people have developed the habit of drinking a cup of coke every day. This is because caffeine and special formula in cola are addictive. Although there are already low-calorie cokes on the market, there are still many people who can't adapt to the special taste of sugar substitutes. If you can't live without coke for a day, you'd better do more exercise to consume excess calories. Because one can a day can make you gain 8 kilograms a year later. Even more frightening is that the cola you drink will not only make you feel full, but also make you eat more food because of its strong taste. Not only cola, but also other soft drinks, root beer and so on. Suggestion: If you really can't give up coke, you'd better choose low-calorie coke instead of sugar. .
