I lost weight myself. I lost weight in one and a half months 18kg. I am a boy, and I think three months is enough.

Losing weight is actually reducing fat, so that the body consumes too much fat, and then we can do some muscle training, because we know that muscles consume energy faster, so we won't let the weight rebound.

Personally, I think it is enough to pay attention to two points to lose weight. The first is to reach the standard of exercise, and the second is to control diet.

Keep the amount of exercise up to standard, and do aerobic exercise for at least 40 minutes every day for at least six days a week. No matter what exercise you do, you should stick to it. Running is ok, so is swimming. I think these two are the best. If possible, swimming is the first choice, which is the least complicated exercise for body joints, followed by running. Running can be independent of external factors, which is good. At that time, I ran for 35-40 minutes every afternoon to lose weight. Because I started to consume fat after 20 minutes of exercise, I used to consume all the sugar in my body, so I had to stick to it for more than 20 minutes. But if my body can't stand it at first, I don't need to run for 40 minutes. I can add it up to 25 minutes, and it will get better and better gradually.

The second is to control the diet, strictly control the diet, don't eat too much, just 7-8 minutes full, don't eat too much, if you want to lose weight, you would rather throw it away than eat. Then you can't eat high-calorie high-sugar high-energy food, and you can't eat sweets at all. You can eat protein, boiled vegetables and fruits and apples. There is also a daily sleep pattern that must be paid attention to. Going to bed early and getting up early will make it easier for you to lose weight.
