Abstract: Dietary restriction regimens are commonly employed to facilitate weight loss in overweight and obese individuals. The dietary restriction regimen most frequently implemented is daily calorie restriction (CR), which involves decreasing energy intake by a certain percentage daily. Another dietary restriction regimen employed, although far less commonly, is alternate day fasting (ADF). ADF regimens include a “feed day” where food is consumed ad libitum, alternated with a “fast day”, where food intake is partially reduced. The present review examines the ability ADF regimens to facilitate weight loss in overweight and obese humans. Changes in dietary adherence, hunger, and fullness that occur with this regimen, and how these changes in eating behaviors relate to weight loss, will also be discussed.
