Calorie requirements in weight loss: an estimate based on self-reported food intake in middle-aged men.
Twenty-eight men participating in a weight reduction program self-recorded foods eaten and calorie consumption for a 15-week period. These food records were examined to estimate calorie needs during weight loss as a function of age, entry weight, height and physical activity level. Only entry weight was significantly associated with calorie need. A predictive equation for calorie need is offered for setting individual calorie intake goals for patient-assessed calorie intake.
