A recent study suggests keeping a food diary can double your weight loss. The study, coordinated by the Kaiser Permanente Center for Health Research and conducted at Duke University Medical Center, Johns Hopkins University and other sites, involved nearly 1,700 overweight or obese adults ages 25 and older. Subjects maintained food diaries for six months and were encouraged to eat a healthy diet and stay physically active. They also met on a weekly basis to discuss their food diaries in a group format.
