The biggest obstacle is that I am a dry and not fat girlfriend. When we lose weight, we must get rid of some greasy food, control our diet and go out to exercise more every day in order to lose weight successfully. Every time I make up my mind to lose weight, my best friend will ask me out to dinner. Because my best friend has lived with me since freshman year, we will call each other no matter what we do, and we will not neglect each other because we have new friends. When I was in college, my best friend stayed at home for a month because of illness. During the month when she was resting, I successfully lost ten pounds. I stood proudly in front of him to show off my achievements. As a result, he only used one sentence. Will you gain weight soon? To refute me. When he told me this, I knew he would go back to campus and start taking me to eat delicious food. My best friend has a very enviable figure, and his constitution is that he will not get fat no matter how he eats, so it's very unlucky for me to eat with him, because I am obese, and if I eat something, I will get fat. We look very bloated when we stand together. My best friend is a bit withdrawn, and there are few new friends in his life, so he will take me with him no matter what he is doing. Every time he wants to eat delicious food, I want to refuse, but I am afraid that she will be lonely, so I have to bite the bullet and go with him. Every time she will order a lot of dishes in front of me, I am a person without determination. Every time I see those delicious foods, I can't help but want to eat them, so my weight loss plan always fails again and again. Now we don't work in the same city, but he still sends me a lot of fat snacks on time every month, because those are his favorite foods. Although I gave some snacks to other colleagues, I still have to eat some to satisfy him, so I have never succeeded in losing weight.
