avoid sugar- if you want to lose weight. Eat good breads instead like whole grain/wheat bread and not the white white bread.
Avoid Alcohol- basically it is a free glucose but coupled with side of food it could contribute to your gaining weight.
Exercise to lose weight.
Eat only when hungry and just enough, chew your food thoroughly and take time chew, because when you chew a food really good it sends impulses to your brain that you already ate a lot though just enough.
