Don't listen to them. According to your current weight, it should be about 260 Jin, right? Such a high base is very easy to lose. I guess you eat more at this weight, don't you? If so, you must control your mouth first. Have a good breakfast, but eat less than usual. Eat 6-8 full lunches. You can eat rice as the staple food, but you must eat less, eat more vegetables and drink more soup. Five full meals are enough for dinner. Try to eat more fruits and vegetables for dinner, or just drink porridge and milk. Not the staple food.
Don't eat fried, greasy, salty and sweet food, don't drink any drinks, drink more boiled water and eat more fruits and vegetables.
Be sure to cooperate with exercise. Do at least 1 hour brisk walking or jogging every day. These two exercises will definitely have a good effect on you.
Listen to me, if you persist in this way for a week, you will lose about 5- 10 kg in at least one week. Please see if it works. If not, it's not too late for you to go to the beauty salon to lose weight!
