Weight loss follows the 80/20 rule, so 80% diet, 20% exercise. Unfortunately, humans are terrible at eating less, since you've been well trained by both evolution and society to eat as much as possible. So then there are things like, eat mostly fruits and vegetables, which aren't very efficient at giving you calories (since you're not a cow, that can extract the full set of calories from vegetables using its 4x stomach). Or become a vegetarian or choose a no-carb diet, maybe that makes it easier by just deciding ahead of time you won't eat anything calorie-efficient. Or exercising and living a more healthy lifestyle, can also help you not feel as hungry as often. Or keep a food diary. Or count calories. Or track your weight. Or train your self-control. But ultimately all just psychological tricks to just eat less calories, and which one works is different for everyone, since everyone's mental makeup is different. If you can't make it happen psychologically, then you can also make it happen physically, by getting a gastric band or gastric bypass surgery.
