Eating beef every day can't solve the problem. There must be a scientific method. 1. A balanced diet can increase calories by using high-fat and high-sugar foods such as cream or other edible oil, jam and sugar. 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! You can consider milk, almonds, sesame seeds, cashews and other foods to gain weight. You can add almond and sesame powder to milk, and cashew nuts can be eaten as snacks, which will have a good effect. In the population distribution structure of society, underweight is also a very common ethnic group. Only in the current wave of social weight loss, those who are underweight are the envy of ordinary people. But in fact, underweight people are prone to malnutrition, fatigue, depression, muscle loss and other symptoms. In severe cases, immunity will deteriorate, and it is easy to get sick, especially for the elderly with chronic diseases, which will increase the chances of complications and have a poor prognosis. Weight gain without weight gain is different from theoretical weight gain. Because "gaining weight" means increasing the proportion of fat in body tissues, and "gaining weight" should include the growth of muscle tissues in addition to the increase of fat. I think what you want to ask is "gain weight" instead of "gain weight"? ! The weight of human body comes from internal organs such as bones, muscles, fat and water. Meaningful "weight gain" should focus on the increase of the ratio of muscle to fat. So, how do we carry out the physical transformation project? The answer is still "diet" and "exercise"! Diet: In terms of diet, a high-protein and high-calorie diet is the only way to gain weight. Concentrated protein and high-calorie foods, such as heavy cheesecake, small cakes, small cakes, etc. Papain or comprehensive enzymes should be supplemented in time after meals to help digestion, so as to increase the digestion, absorption and utilization of food. Protein chooses excellent protein sources, such as eggs, milk, meat and poultry, which should account for more than half of the daily protein. Soybean protein powder, which is separated and extracted from plant protein, will have a better effect because there are fewer plant fibers that hinder absorption. As for eating meat or drinking milk, which method is better? People who pay attention to efficiency can try to drink high-protein milk powder (such as Sanduo milk protein), which will have higher intake and better absorption and utilization rate than protein who drinks ordinary fresh milk and eats meat. The choice of sugar is also an important part. Choose foods with high starch content, such as white toast, steamed bread, white rice, sweet potato, taro and pumpkin. When cooking, you can add some maltodextrin (commonly known as corn hydrolyzed starch, which can be eaten directly in food) in the form of glutinous rice, soup or thick soup, or in soup or juice and milk to increase calorie intake. In the choice of fat, medium-chain fatty acids (MCT) with good absorption and utilization rate can be appropriately used to increase the intake of concentrated calories. Pure medium-chain fatty acids (MCT) need to be used together with general oils and fats because they do not contain "essential fatty acids". It is suggested to use medium-chain fatty acid products to mix essential fatty acids (such as sanduo high energy) to avoid the lack of essential fatty acids. It is generally recommended that medium-chain fatty acids account for 60% of the total oil consumption. People who want to gain weight take "weight training" as the main way of exercise, rather than "aerobic exercise" emphasized by people who lose weight. Because "aerobic exercise" promotes energy consumption, and "weight training" is used to increase the proportion of muscles. With the help of dumbbells, barbells and training equipment, combined with the complete contraction and relaxation of large muscle groups, muscle construction can be realized. So what is the big muscle group? It is what we call chest muscles, abdominal muscles, back muscles, leg muscles, biceps and triceps (arms). Through weight-bearing training and dietary supplement, large muscle groups can grow, and relatively, they will also accumulate some weight.
