This 10-week food and exercise diary is simple to use and very effective. University studies show that persons who use a food diary not only lose more weight, they also keep it off! It is non-dated so can be started anytime. There are separate columns for food calories and exercise calories. At the end of the day columns are totalled and exercise calories can be deducted from food calories. A further column allows for fat grams. Also included are a Weekly Summary Page and room for the counsellor to add comments.
