First of all, we must gain weight scientifically and gain weight for health. Besides a balanced diet, you should also keep enough and good sleep. If people get enough sleep, their appetite is better, which is also beneficial to the digestion and absorption of food. Many thin people like to spend the night, always play all night, and have to go to work the next day, which seriously affects the quality of sleep, so it is strange not to be thin. Personal mental health should also be paid attention to. Tension and pressure at work, obsession with small things in life, and "crazy" study or work beyond human load will make people thin. On the contrary, a happy mental state and harmonious interpersonal relationship will help you gain weight. Appropriate exercise For those thin people who sit in the office for a long time, take some time to exercise every day, which is not only conducive to improving appetite, but also to making muscles strong and healthy. The muscles of the human body are "put into use and discarded". If you don't exercise for a long time, muscle fibers will contract and weaken, 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 people have a big appetite when eating. Generally speaking, a large amount of 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.
