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. Adopt a balanced diet and gradually increase food intake to avoid compulsive supply and destroy appetite. 2. Develop good eating habits, eat regularly and quantitatively, eat in small quantities and eat slowly. 3. Change the dining procedure. Eat foods with high concentration and high nutritional density first, and then eat other foods. 4. Choose moderately cooked foods. Choose moderately cooked foods, such as steaming, stewing, marinating, frying, cooking, etc., to avoid the food being hard and difficult to digest due to frying, frying, baking, etc. 5. Keep a happy mood, arrange a good dining environment and concentrate on eating. 6. Choose nutrients that are easy to absorb and transform (for example, the patent of total nutrition developed by Zhejiang University: Vitter nutritional liquid powder, etc.). Stress and anxiety not only affect appetite, but also the digestive and absorption function of gastrointestinal tract is not good, and the increase of metabolic rate consumes relatively more calories. If there is still no way to improve your slim figure, I suggest you contact a professional dietitian and doctor to help you find out why the meat can't grow, and grow healthy meat in a healthy way! Special reminder that under normal circumstances, underweight is related to genetic factors. At the same time, some people who are easily excited can accelerate the consumption of calories due to the influence of endocrine. Some people are easily nervous, and the result may be missing a meal or losing appetite. It is natural to lose thousands of calories at a time, so it will definitely not be fat. If you find yourself underweight and thin, you should first check whether it is the potential influence of the disease. Such as thyroid, diabetes, adrenal gland, digestive system diseases, etc., are easy to cause underweight. Only when the disease is ruled out can the fattening plan be implemented. In terms of diet, many thin men and women who are happy in body and mind are picky eaters and partial eclipse. Therefore, we should get rid of these bad habits and increase the intake of meals, which should be rich and varied. Eat more carbohydrates, pasta is the most useful. In addition, high-protein foods, vegetables and fruits are indispensable. On weekdays, it is also a good idea to eat healthy snacks, such as peanuts and toffee, and then drink some juice after drinking beer. In the case of adequate intake of protein, it is advisable to eat more foods rich in fat and carbohydrate (starch, sugar, etc.). In this way, the excess energy can be converted into fat and stored under the skin, making the thin body strong. Thin people with weak gastrointestinal function can choose the liver of chicken, duck, fish and sheep to eat. In addition, fish is easy to digest and absorb. If you want to gain weight by eating a variety of diets, you should first gain weight scientifically and gain weight for health. Besides a balanced diet, you should also keep adequate and good sleep. If people get enough sleep, their appetite is better, and it is also conducive to the digestion and absorption of food. Many thin people like to spend the night, playing all night at every turn, and going to work the next day, which seriously affects the quality of sleep, so it is strange that they are not thin. Attention should also be paid to personal mental health. The tension and pressure at work, the obsession with small things in life, and the "crazy" study or work beyond the human load will make people thinner. On the contrary, a happy mental state and harmonious interpersonal relationship will help to gain weight. Appropriate exercise For those thin people who sit in the office for a long time, they should take some time to exercise every day, which is not only conducive to improving their appetite, but also to making their muscles strong and healthy. The muscles of the human body are "put into use and discarded". If you don't get exercise for a long time, the muscle fibers will shrink relatively and become weak, and people will look thin. In terms of exercise mode, jogging is a good choice, because the number of gastrointestinal peristalsis increases obviously when people jog, which can consume human energy and make them have a good appetite when eating. Generally speaking, large-scale exercise, short-term exercise and rapid explosive exercise can all have the effect of gaining weight, which is also the most taboo for people who want to lose weight.
