For Macronutrients, I should be consuming Carbs at 45–65%, Protein at 25– 40% and Fat at 10–15%. How do I keep track of these numbers?
Start by writing down what you eat. It only takes minutes everyday. You will quickly begin to understand portion sizes and the amounts of calories, carbs, protein and fat that constitute most of the foods you eat. Remember, carb and protein calories represent 4 calories per gram and there are 9 calories per gram in fat.
