About diet I'm not on a diet now. But I 'm taking care of my weight as much as possible. Restricting foods and exercising reguraly are really common for diet. Recently a low carb diet is getting very popular. I heard it from a person who succeeded to lose his weight by this diet. I think it is strict that you are not allowed to eat white foods like bread or sugar. Even though you are allowed to have one cheat day a week. Many people are health conciouse. So some sports gyms have a lot of those people. I t seems that they prefer to be healthy rather than lose weights.
