Effect of low-calorie ketogenic vs low-carbohydrate diets on body composition and other biomarkers of overweight/obese women: An 8 weeks randomised controlled trial

This study investigated the effects of a low-calorie ketogenic diet (LCKD) (10–15% carbohydrate, 60–75% fat, 10–25% protein) compared with a low-carbohydrate diet (LCD) (40% carbohydrate, 30% fat, 30% protein) on body composition, fasting blood sugar (FBS) and lipid profile in overweight/obese women. The results showed a significant difference (p-value ≤0.005) in the change of the BMI (−2.79 and −1.88 kg/m2), basal metabolic rate (BMR) (−72.45 and −50.42 kcal), skeletal muscle mass (SMM) (0.68 and 0.67 kg), muscle mass (MM) (2.2 and 1.0 kg), fat-free mass (FFM) (−2.34 and −1.04 kg) and visceral fat rate (VF) (−3.55 and −1.95) between the intervention groups (p-value
