Effects of different dietary intake on BMI. A Changes in BMI over 12 weeks in 4 groups. B Changes and net change in BMI over 12 weeks in the LC diet groups. The net change in BMI in the LC diet group was −0.6 (−0.9, −0.2) kg/m2 compared with the LC+CR diet group (P < 0.001). C Changes and net change in BMI over 12 weeks in the CR diet groups. The net change in BMI in the CR diet group was − 1.6 (−2.0, −1.3) kg/m2 compared with the LC+CR diet group (P < 0.001). D Changes and net change in BMI over 12 weeks in the LC diet group and CR diet group. The net change in BMI in the LC diet group was −1.0 (−1.4, −0.7) kg/m2 compared with the CR diet group (P < 0.001). Total numbers for each diet group are as follows: NC diet, n=74; LC diet, n=76; CR diet, n=72; LC + CR diet, n=76. NC, control; LC, low carbohydrate; CR, calorie restriction. Numbers in parentheses are 95% CIs. ×P < 0.05, *P < 0.001
