I would really advise against taking any health advice from random people on a video game website. If you’re looking for information on that, I recommend talking to a health professional.

Eat less, move more.

Uh, idk.

Eat food with low calorie and take exercises

It really depends a lot on whether you're a man or a woman due to testosterone or estrogen hormones being dominant in your system, how fast is your metabolism and such things. I think that if a person has tried balancing their diet and move more, but that yields no results - they should talk to a professional, cause it's not just one solution for all people really. I, for example, have a moderate metabolism, I'd say and I eat maximum twice a day, but I cut no sugar, I don't move particularly much (except a couple of exercises in the evening just to keep muscles in a decent shape) and that's enough not to grow weight. For others it may not be this easy, so

Try to start fitness for example. I also try to have loss some weight and used low carb diet and coolsculpting on but after that procedure I will attend to fintess lessons and continue my diet.

I like how this thread gradually gets more posts, even when the original poster has deleted himself from the site.

Jeez, I drink 1.5 liter per hour sometimes, is that bad? Why is it?

At the very least, if you ingest too much water at once it'll go straight through your body without providing much benefit.
