So I can totally understand your feelings, but what I want to say is that there are still some ways, and that is fitness. Fitness can make you stronger, and then you can make your body healthy. I think fitness is not an easy thing for thin people. First of all, I think you need to have a certain fixed time. The best time for exercise is four or five in the afternoon. You can go to eat after exercise, and then eat a lot. For fitness, I think it is the chest and shoulders that can be practiced, which can make people look stronger.
Then you can also practice abdominal muscles and squats, because squats can increase the strength of the lower body. After practicing squat for a month, I obviously felt that my legs became thicker, and then my leg muscles became bigger. Then I can exercise the lines of my shoulders and chest with dumbbells. Actually, I don't have to go to the gym to work out, but I can stay at home. A set of dumbbells, a yoga mat and a fitness app will do. I think it's good to recommend keep here.
Then in terms of diet, I think you can eat some high-protein foods, such as egg protein, or just protein powder, and don't eat some fried unhealthy foods, which is not good for your health.
