Have you ever heard someone say, “you are what you eat?” It could be that you just thought people used this phrase to promote healthy eating but, actually, you are what you eat. For example, the amino acids contained in the tuna from a tuna sandwich are digested and used by your body muscle building and cell growth. When you ingest too much junk food, you may find that your skin color changes and you appear fatter, whereas when you consume healthy foods, your overall appearance is slimmer. So, diet is the first place to get started when you wish to lose weight. There’s no point in exercising if your diet is not healthy! You have to ensure your diet consists of meals that are nourishing! When it comes to teen weight loss it can be a very sensitive subject.
