Protein powder can promote muscle growth, but can not play a role in gaining weight. Protein powder is generally the use of purified soy protein, or casein, or whey protein, or a combination of these proteins, composed of powder, its use is for the lack of protein supplementation of protein. Protein is the most important nutrient to ensure the health of the organism, it is necessary for the maintenance and repair of the organism as well as the growth of cells, it not only affects the growth of organismal tissues such as muscle, but also involved in the production of hormones, maintenance of immune function, other nutrients and oxygen transport, as well as the production of hemoglobin, blood coagulation, and many other aspects.

Gaining weight is just as difficult as losing it, and requires not only determination but also perseverance. Here's how you can gain weight without compromising your health:

1. Eat smaller, more frequent meals rather than increasing the size of each meal. Choose foods that are rich in nutrients, meaning foods rich in vitamins, minerals and calories.

You're underweight because you're not getting all the vitamins, minerals, and especially iron that your body needs. You must eat plenty of foods that are high in nutrients, low in cholesterol, and unsaturated fatty acids, such as lean meats, fish, low-fat cow's milk products, fruits, vegetables, and legumes, and supplement them with high-calorie foods (such as sweets), and fat-rich foods (such as margarine).

2. Eat what you want to eat, not just what you "have to" eat. Instead of just eating desserts (such as ice cream, milk, cakes, etc.), you should eat more ordinary food, such as sesame seed cake, cheese, raisin bread, butter, and so on. As long as it suits your taste, whether it is to be chewed, sucked, cold, hot or creamy, enjoy it as long as you like.

3. Tips for eating foods with high calories. Skim milk powder added to juice, sandwiches with butter and meat loaf, and fried ribs topped with two tablespoons of butter all take in more calories. You can also choose higher-calorie foods and mix high-calorie with low-calorie foods, such as tacos with coffee or tea.

4. Mimic the Weight Watchers technique, but use it in reverse. For example, keep ready-to-eat foods or snacks at home, school or the office. Put some raisins, walnuts or snacks in a glass jar; put some cheese or ice cream in the freezer; put some fruits in a basket at the dining room table that you can pick up anytime you want; put some chocolates, walnuts, potato chips, crackers, etc., in your purse and have something to eat whenever you want it.

5. Pay more attention to your oral health. Eat more snacks, but also pay more attention to your oral hygiene, you must be more diligent than usual to brush your teeth and rinse your mouth. Eat less sticky, sweet food.

6. Record your food, exercise and mood changes throughout the day. Many women realize that their inability to gain weight is due to the fact that they are so emotionally stressed at work or school that they forget to think about eating.

7. Often with friends who love to eat, together to eat a lunch, dinner, parties or picnics.
