A 3-month calorie-restricted ketogenic diet (KD) produces significantly greater weight loss than a calorie-restricted Mediterranean diet (MedDiet) in adults with obesity.
To lose more weight than a standard Mediterranean diet in 3 months, switch to a ketogenic diet with a 600-calorie daily deficit. This means eating very few carbs (5% of calories), moderate protein (30%), and high fat (65%). Ensure you are consuming enough calories to maintain basic function but below your maintenance level.
Significant differences in weight loss from baseline to 3 months were found between KD and the control group [− 3.78 kg (− 5.65 to − 1.91 kg)]... These results suggest that a calorie-restricted KD... may be more effective for weight loss than a calorie-restricted MedDiet in obesity.
Why this rating
Randomized clinical trial with 140 completers, but short duration (3 months) and lack of blinding.
