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 to help digestion, absorption and utilization of food. Protein should choose excellent protein sources, such as eggs, milk, meat and poultry, which should account for more than half of the daily protein. Soybean protein powder separated and extracted from plant protein will have 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. ◎ Choice of sugar The intake of sugar is also an important link. Choose foods with high starch content, such as white toast, steamed bread, white rice, sweet potato, taro and pumpkin. Cooking can be in the form of glutinous rice, soup or thick soup, or some maltodextrin (commonly known as corn hydrolyzed starch, which can be directly added to food) can be added 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, 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. At present, in the United States, we have been trying to carry out proper weight training for the elderly and supplement them with weight-increasing foods to increase the proportion of muscles, thus improving symptoms such as malnutrition, fatigue, depression, muscle failure, poor immunity and easy illness. For the elderly with chronic diseases, it will also reduce the chances of complications and poor prognosis. Breakfast: You must eat to be energetic! People who prefer western tastes: 1.
