First of all, you're not fat, plump, or beautiful. You're fine. At this age of long body, controlling diet or eating indiscriminately will have an impact on your physical development. I don't know how long you want to lose weight, but it is worth noting that those diet pills or foods online are absolutely not allowed to try. I have my own way to lose weight. My normal weight is about 90 kg in summer, and I will gain weight 105 kg in winter. I start practicing yoga posture every spring. In two months, my weight will reach 90 kilograms. I don't diet, I don't take medicine, and of course I don't overeat. Eat some fruit and drink some boiled water half an hour before eating, and then your appetite will decrease. Plus yoga (40 minutes a day to 1 hour), you can lose more than ten kilograms in two months. This is what I do every year. I believe you can do it, too. I'm doing this position. Now I feel weak because I often do it. I'm creating more difficulties for myself. Now I can straighten my upper body and keep my feet with my body. I have to change my left and right legs for this position.
