Chocolate is indeed high in calories and easy to gain weight, but it can't be the only staple food for you to gain weight. Can only be used as a snack after meals. I know you don't want to be fat all over, just want to be healthier. In fact, everyone wants to be healthy. This mentality is understandable, but I think it is not enough to gain weight unilaterally. I think you can start with the usual bits and pieces. After three meals, you can always prepare some desserts for yourself, or have supper at night. These are good helpers to assist your weight gain plan, which can not only improve your gastrointestinal activity, but also adapt your body to the process of eating less and eating more meals. Why not? I used to have a brother-in-law who went to the hospital because he smoked for a long time and had a bad appetite.

He told his brother-in-law the beauty of conditioning and fattening.
