It's not your fault to be fat, and it's not your fault to be fat even if you don't eat. You can't ignore your daily dietary needs in order to lose weight. You can ask a dietitian to specify a diet for you, eat more vegetables and fruits, and reduce the intake of fat and fried food. Exercise is not blindly consuming physical strength. Go to a fitness instructor, go wherever you want to lose weight, and maybe even get married with a fitness instructor (also a woman).
It is healthy to lose weight slowly, because losing weight suddenly in a short time will lead to skin relaxation and some physical function damage. Slimming down slowly also means that you need to stick to it for a while. Where did you get a good figure if you didn't insist? So don't be discouraged if there is no obvious change in weight. Success belongs to the persevering. There may be another reason why the weight change is not obvious. When you exercise more, some of your fat will become strong muscles, and the density of muscles is greater than that of loose fat, which means heavier. Don't worry, you are still thin.
Don't feel inferior even if you don't succeed in losing weight in the end. Who says fat people can't live a confident and wonderful life? Look at foreign network celebrities, not the standard pointed chin, but confident fat people. China is also a confident fat man, teaching people how to make themselves more beautiful by using makeup techniques. Why have you been unhappy about the weight you can't lose? But good luck losing weight.
