First, it's better to tell your girlfriend that she doesn't like her thin appearance than a panacea. If your boyfriend wants to discourage his girlfriend, he has to tell her that he likes her fat appearance and doesn't like her thin appearance. Girls like to listen to their boyfriends. When they talk, they all say that they don't like the way their girlfriends lose weight, and girls will naturally stop losing weight. Not all men in life like their women to be thinner, so if boyfriends tell their girlfriends more about this, their girlfriends will give up the idea of losing weight.
Second, boyfriends spend more time with their girlfriends and take her to crowded places. Why does his girlfriend always lose weight? Because his girlfriend lives with low self-esteem. She thinks she is too fat and everyone around her is thin. Only she is fat, so she wants to lose weight. Only by finding out the reason why his girlfriend wants to lose weight can he help her break the idea of losing weight. Boyfriend can cultivate his girlfriend's self-confidence and take her to crowded places to play, such as shopping, watching movies and fitness. Although my girlfriend is fat, she is accompanied by her boyfriend, so she is confident and won't feel ugly. Boyfriend can tell her when there are many people and tell her that she likes her chubby appearance, which will make her girlfriend very confident.
Third, boyfriends should tell their girlfriends about the dangers of excessive weight loss. Since two people have nothing to say, tell their girlfriends directly about the dangers of excessive weight loss, because excessive weight loss will lead to many diseases, so we should lose weight moderately and don't always criticize our body. As long as the body is healthy, it is the most perfect state. I believe my girlfriend will be particularly moved after hearing her boyfriend's words and will give up the idea of losing weight.
