A low fat diet will help you to find weight not lose it. See site below for explanation as to why.
The best answer I can give you is to try a few different diets and see what works the best for you. Most diabetic diets work really good, and could lower your chances of getting it later on. You could try counting calories, set a limit for yourself, start with no more than 2000, then 1800, etc. The combination of a low calorie diet and exercise work on most everyone.
Doesn t matter if the diet is high or low fat, high or low carb.You have to cut your calorie intake below what you are burning on a daily bases.Either restrict you food intake or increase you physical activity to burn more calories.Most low fat foods, are packed with the same calories, due to increase sugar content.
All you have to do is watch what you eat in small portions 5 times a day and do exercise. Drink lots of water and fruits rich in fibers. Goodluck
eat the right foods plenty of exercise
