Being thin is not only related to your genes, but also to your intestines. You should be a person who eats easily, and your fingers should be slender. Do you defecate easily when you eat pears? I am one of these people, with slender fingers. Eating cool fruit is easy to go to the toilet. If you want to get fat at this time, you can't eat high-fat food. Foods high in fat will only increase your fat. You should start to repair the intestines, eat nutritious food, and supplement protein, cellulose tablets and calcium-magnesium tablets. It is recommended to eat Nutrilite. If you think this is too expensive, you can choose to detoxify and give your stomach a thorough cleaning, not with water ~ fresh juice.
