Many fitness and nutrition experts suggest using a journal to keep track of exercise and food intake because it works. Using a journal to keep track of what you eat will let you see where the calories are coming from, and where you need to work on. If you are trying to lose weight you might want to cut out extra sugar and calories. If you want to gain muscle then you might want to eat lots of protein, and bulk up.
