First, is your girlfriend really fat? Is it necessary to lose weight? Is her body mass index higher than the healthy level? Did she get fat because she didn't exercise all day and ate high-calorie greasy junk food? Does she have obvious inferiority complex and psychological obstacles in her figure?
If the answer is yes, then I fully support your idea. You want your girlfriend to lose weight. You can tell her directly that her weight is seriously overweight, which affects her health. She must lose weight whether she likes it or not. Under normal circumstances, my sister will be very sad and anxious at this time. You must tell her clearly that you are not disgusted, but want to help supervise her to improve herself so that she will not be afraid of the hard work of losing weight. You will stay with her until she becomes what she wants. Finally, my sister will understand that a healthy and beautiful body is happier than more fried chicken pieces, and that kind of heartfelt confidence must be different.
If the answer is no, then her daily eating habits are normal, that is, her figure is average and not perfect. What I want to tell you is that you can't have your cake and eat it. You see other people's girlfriends have long legs and thin waist, but you should know that when you hold the soft and lovely meat on your girlfriend's stomach, the satisfaction of other people's boyfriends will never be realized. Your girlfriend is a meat eater, always greedy for snacks and never pays attention to dressing herself up. She wears a large T-shirt and jeans, which makes her look less embarrassed than others, but she looks silly and happy when eating, which often makes you laugh and cry. But do you know that other people's boyfriends are upset because their girlfriends are too thin to eat this or that? Is it helpless for others to praise you for your good luck? You can't see it.
No girl doesn't love beauty. She doesn't say that losing weight doesn't mean being unconscious. What girls hate most is the cynicism of others, whether it is appearance or body shape. Remember to be sincere, not to say that someone else's girlfriend is thin and hurts her. Look at the mall and see if you are dressed well.
Generally speaking, verbal persuasion is useless and there may be conflicts. The best way is to start from yourself. Get two fitness cards, give her one, and go to the gym together; Take her to outdoor activities, such as mountain climbing, rock climbing, cycling and swimming, and turn eating snacks at home into exercise together, sweating together and seeing more scenery; Take her shopping, quietly buy a skirt that she likes but can't wear, as a goal, and give it to her after she loses weight; Buy her a small gift to encourage her when she is slimming, praise her with surprised eyes and give her confidence and courage. Most fat girls are sensitive, so please protect them. I believe that if you can do this, your girlfriend will not be angry with you, but will gradually become thinner and the relationship between you will get better and better.
But you want to make her better and you don't like her. If you are looking for an answer with disgust, then I advise you to give up. Good love is that two people get better together, rather than cheating and degenerating each other.
