How can i get a healthy diet or how do i keep up with healthy diet ?

A variety of foods: Healthy diets have natural foods that take time to chew but contain few calories. Examples include carrots, celery, and leafy lettuce (little or no salad dressing). 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. Surely avoid sugars and simple starch calories. Eat some protein with each meal.
