On the one hand, you can tell her what you think and coax her a little, such as "Dear ~ Do you love me?" Then tell her that you want to lose weight slowly. Don't be impatient. Girls have a big temper. If you just say, you can't. If your girlfriend is fat, you should talk to her about the harm of obesity, for example, for your future healthy growth and her future health, and then you can promise to exercise with her to lose weight if you want. During exercise, two people can lose weight and promote their feelings. Praise her when she makes a little progress, and you will stick to it and never say that again. Girls should be spoiled ~ Come on! Or tell her I'd like to see how thin you really are. If it's not enough, then make yourself black and blue. Tell her that someone next door said you were fat and I had a fight with him. Or you can put it mildly. For example, you would be more beautiful if you were thinner, although you are not fat now. . . . Your girlfriend certainly wants to be thinner and more beautiful, but her personal constitution is different. Some people don't have a good way to lose weight, and it's not easy to lose weight, but some people won't get fat even if they eat it. Yours, I believe, must be trying to lose weight. . . . . You can spend time with your girlfriend, do some outdoor activities, cultivate feelings and lose weight. . . In fact, he is not too fat. Don't just call him fat. Women's weight is a taboo. . . Really can't. Take your time and tell her when you have a chance. Don't always bring it up in front of her. In fact, every woman wants to show her best. Besides, maybe she hates herself more. She just told you in anger, and then said it from the side, to put it mildly! Who doesn't want to hear good things? Besides, if she really loves you, she will think about it and lose weight. Every woman wants an elegant devil figure.
