I love eating..cheese butter milk products am very foodie but i dont want belly fat..what shud i do? only gym is an option?

It's simple math: Belly fat can be lost in three ways. If a person eats fewer calories than he needs to live on each day, his body will use the stored fuel (fat). If a person exercises more than he did before, but does not start eating more calories, then his body will also use the stored fat. A surgeon can remove fat cells containing the fat, but the person will regain fat in stranger places if he overeats later.
