You see, you can be confident if you are so fat.
If the topic is just to have a slimmer friend and a slimmer lover come to make yourself look longer, I think this is actually an unnecessary move, but if such a person you care about has affected his real health and his real competitiveness in society because of his physical problems, and he can't face up to his body, then it is really necessary to tell him that he is really fat and needs to lose weight and control his body.
When you decide to persuade a fat man to lose weight, the first thing to understand is what is the relationship between this person and you. Is he your parents? Is it your friend? Is it your lover or the fat man himself?
For different people, there should be different ways to deal with it, and your attitude should be different. If it is out of concern for an elder, then sometimes it is not good to say it directly, which seems arrogant. You can directly put some persuasion ideas into action, such as providing him with more healthy food. Show him some reports, news or books related to this aspect, and subtly input this concept into the minds of elders, so that they can realize their own health defects and that losing weight is of practical significance to a person's health, then they may go in to lose weight.
If you want to persuade your friends to lose weight, then this method can be more intense. Sometimes you can give some comments directly, such as praising a person's figure, or making a less intense rational evaluation of your friend's figure to make her realize her obesity. When I take her shopping, I can occasionally bring some clothes that are small in size but really beautiful in style, so that he can feel the inconvenience caused by his body and feel that he can lose weight more. It is relatively simple for a friend to persuade him. Of course, those offensive words should not be used on friends, which will not only convince you, but may also cause certain problems in your relations. You think you are kind to her, but she may just think you are very picky.
If this question is only an answer to your inner hesitation, then don't think about it, reduce it, since you can't fully accept your current figure, then work hard. To tell the truth, the world is really unfriendly to ugly ghosts, fat people and stupid children.
