Oral diet pills are not advisable. Nowadays, many unscrupulous businessmen make so-called fast-acting and non-rebounding diet pills for their own interests, all of which are deceptive. Never lose weight in this bad way again. Besides, you should still be in the learning stage, as long as you have a reasonable rest, control your diet (of course, you can't go on a diet), and create an effective and healthy way to lose weight: insisting on exercise will definitely have an effect.
Of course, don't pay too much attention to the comments of classmates or others. Who doesn't talk about people before and who doesn't talk about people after? Right? No one in this society is perfect. As long as you are healthy and happy, family harmony is more important than anything else.
I wish you success in losing weight as soon as possible!
