Along with avoiding sugar and sugary
foods you need to limit your
carbohydrate and starch intake as these
foods quickly turn into sugar after eating. For example, potatoes, white rice, foods made with white flour - breads, crackers, etc. Eat lean meats, fish, poultry and vegetables. Avoid snacking before bedtime. Use Google search on 'good carbs vs bad carbs' and the Glycemic Index to understand proper nutrition.
