A separate two-year study comparing adherence to low-carb, low-fat, and Mediterranean diets showed higher adherence to a low-carb diet during the first six months, but lower compliance overall and more drop-outs among the low-carb group by the end of the study.
Maintaining weight loss is challenging no matter what type of diet you follow, partly because sticking to a specialized diet for long periods of time is difficult. Recent research showed that adherence to a well-formulated ketogenic diet was similar to that for the Mediterranean diet during the 12-week crossover study, but that adherence to keto was lower during the 12-week period that immediately followed the 24-week intervention. A separate two-year study comparing adherence to low-carb, low-fat, and Mediterranean diets showed higher adherence to a low-carb diet during the first six months, but lower compliance overall and more drop-outs among the low-carb group by the end of the study.
