Values are mean ± SD. Subjects are divided into four groups: male weight maintainers (WM, n = 59), weight regainers (WR, n = 100) and female WM (n = 135) and WR (n = 175). Weight maintenance score (WMS) is calculated at the end of the 6-month ad libitum diet: (weight after 6-month ad libitum diet − weight after LCD)/(weight at baseline − weight after LCD)
WC waist circumference, LCD low-calorie diet, WMS weight maintenance score
* P < 0.001 change from baseline versus after 8-week LCD with dependant t test per group
# P < 0.001 change from after 8-week LCD versus after 6-month ad libitum diet with dependent t test per group
