There are many reasons for not eating fat. Physiological factors include: diseases, gastrointestinal function, drugs, psychological factors such as anxiety, tension, depression, etc., as well as bad eating and living habits. Professional nutritionists also provide some methods that you can use as a reference when making food and nutritional choices in life. 1. For a balanced diet, high-fat and high-sugar foods such as butter or other edible oils, jams, and sugars can be used to increase calories. Although weight gain is relatively rapid, long-term or excessive consumption will destroy appetite and may cause chronic obesity. Disease threatens health. Adopt a balanced diet and gradually increase food intake to avoid forced supply and destruction of appetite. 2. Develop good eating habits: eat regularly and quantitatively, eat small amounts frequently, and chew slowly. 3. Change the meal routine. Eat foods with high concentration and nutrient density first, and then eat other foods. 4. Choose moderately cooked food. Choose moderately cooked food, such as steaming, stewing, stewing, stir-frying, boiling, etc., and avoid foods that are hard and difficult to digest due to frying, frying, roasting, etc. 5. Keep a good mood, arrange a good dining environment, and concentrate on eating. Stress and anxiety not only affect appetite, but also poor digestion and absorption function of the gastrointestinal tract. Increased metabolic rate will consume more calories.

Diverse diet: Thin people should increase their dietary intake and the dietary content should be rich and varied. Mainly eat carbohydrates, pasta is the most effective. In addition, high-protein foods, vegetables and fruits are indispensable, and healthy snacks such as peanuts, toffee, potato chips, etc. must be kept on daily basis. In the case of adequate protein intake, it is advisable to eat more foods rich in fat and carbohydrates (i.e. starch, sugar, etc.). In this way, excess energy can be converted into fat and stored under the skin, making the thin person stronger. Thin people with weak gastrointestinal function can choose liver from chicken, duck, fish, and sheep. In addition, fish is also easy to digest and absorb. Ensure sleep If you want to gain weight, you should also maintain adequate and good sleep. If people get enough sleep, they will have a better appetite, and it will also be conducive to the digestion and absorption of food. Many thin people like to spend the night, playing all night, and then having to work hard the next day, which seriously affects the quality of sleep. It would be strange if they don't lose weight if they continue like this. Be in a good mood. Another thing to pay attention to is personal mental health. Tension and pressure at work, obsessive thinking about small things in life, "crazy" study or work that exceeds the human body's capacity, etc., will all make people lose weight. On the contrary, a happy mental state and harmonious interpersonal relationships are helpful for weight gain. Proper exercise For those thin people who sit in the office for a long time, they should take a certain amount of time to exercise every day. This will not only help improve their appetite, but also make the muscles strong and fit. The muscles of the human body are "use it or lose it". If Without exercise for a long time, muscle fibers will shrink relatively and become weak, making people look thin. In terms of exercise, jogging is a good choice, because the number of gastrointestinal motility increases significantly when jogging, which can consume the body's energy and improve appetite during meals. Generally speaking, high-intensity exercise, short-term exercise and rapid explosive exercise can all have a weight-increasing effect, and they are also the most taboo for people who want to lose weight.
