UNDERSTAND THE NEED OF YOUR BODY:
Try to figure out the needs of your body. You should well determine your hunger times, and the kind of food your body is demanding at a particular moment. For example, after an exercise, your body goes into starvation, and that is the time you need to feed yourselves with carbs to overcome the calorie loss in a healthy manner.
Last but not the least, think about wellness, and not the disease.
