Macronutrients are your proteins, fats, and carbohydrates. These nutrients are what make up the caloric content of food. This is how we get energy. Fat provides 9 calories per gram while carbohydrates and protein supply 4 calories per gram. This is how we figure out the calories in a food source. I will give you these numbers as well as total calories each week on the app. These are custom for you! You will learn to track these amounts on the app. When you reach your goal weight, you will be independent with tracking macro targets so weight loss is maintained!
