If you're serious about changing your diet, losing (or gaining) weight, and improving your health, you'll find that keeping track of things is key to your success. I can help you get started with a food diary. This will help keep you motivated and help you get back on your diet if you have a temporary setback.
Be sure to note the portion sizes and write down the calories you eat every day. Add up the number of calories per day and your total for the week. If you need to lose weight, decrease the number of calories you need to eat each week by 500. For most people, that adds up to one pound per week.
