Im 16 and overweight i want to try the raspberry keytone diet since its natural, but because of my age im not sure if its ok or not?

Avoid fad diet items: Helpful weight loss diets have natural foods that take time to chew but contain few calories. Examples: carrots, celery, green leafy lettuce (little/no salad dressing), etc... When shopping for fruits, buy small ones no bigger than a tennis ball, because fruits have sugar. Drinks without calories include water and green tea. A calorie is a calorie, but surely avoid sugar ; simple starch calories.
