Changes in absolute and percentage body weight and waist circumference in participants after 1 y in a commercial weight-loss program (n = 9037) including a VLCD (500 kcal/d), an LCD (1200–1500 kcal/d), or a restricted normal-food diet (1500–1800 kcal/d)1

All values are estimated marginal means; 95% CIs in parentheses. ANCOVA was conducted, and the values were adjusted for age, sex, center, calendar year, history of cardiovascular disease and cancer during the past 5 y, and dispensation of drugs for obesity, diabetes, hypertension, dyslipidemia, depression, and psychosis during the 6 mo preceding baseline. LCD, low-calorie diet; VLCD, very-low-calorie diet.
