Mean weight loss from baseline to 6 months and from 6 months to twenty-four months in females and male according to macronutrient assignment. For the 102 women on the lowest carbohydrate diets, significantly less weight loss was observed; weight change was −1.8% (95% CI −3.2%, −0.4%), significantly different from men [−5.5% (95% CI −7.2%, −3.7%)] (p=0.0016) and significantly less in women on the lowest carbohydrate diets [−4.4% (95% CI −5.8%, −3.0%)] (p=0.0116). Women lost significantly less weight (−3.2% [−4.3, −2.2]) on the low fat diets than men (−6.0% [−7.3, −4.6]) (p=0.0015), but the low fat macronutrient comparison combines the two highest carbohydrate diets (65% and 55%).
