I think it's easy to lose weight if you gain weight because you eat fast food every day.

first of all, you should control your mouth. You are fat because you eat fast food, so you shouldn't eat fast food any more. In general, if you eat too much fast food, you will gain weight, and this is very unhealthy. The fat content of fast food is very high, and it is easy to gain weight if you eat too much. You can stop eating fast food in the future, and then eat some foods with low fat content, and keep your mouth shut and stop eating fast food. In this case, even if you can't lose weight, you can stop gaining weight. Even you can eat less, eat more fruits, oats, vegetables and so on, and don't drink. Drink more boiled water to promote digestion, which will be good. Then don't eat too much every day, and you can't help eating. Eating too much can't be digested. Don't eat and have no energy to lose weight. So be sure to control your appetite, don't be lazy, and think that you can eat fast food once in a while. You must remember that if you have the first time, there will be a second time, many times, so you must have perseverance and control yourself.

Secondly, I think people who eat fast food are generally lazy, so I guess you don't exercise either. You just sit there after dinner and don't move. How can you not gain weight? Therefore, you can go out for a run every morning and evening, go out for a walk after meals, often go to the gym, find a coach, and lose weight reasonably and healthily. Don't exercise, but you can't exercise too much, otherwise the fat may not be reduced, and it will become muscle, which is not worth the loss.

I think you can buy your own food every day and then cook for yourself. You can walk more when you buy food, just to exercise, and you can also wash the dishes yourself after eating, just to exercise yourself after eating. This will not only cost less money, eat well, but also make you exercise, kill three birds with one stone, why not?
