A recent study on different dietary approaches (eg low carb diets, high carb diets etc) by Alan A. Aragon, Brad J. Schoenfeld.
And the difference they concluded? None!
Calorie deficit and adherence is the key aspect.
“A wide range of dietary approaches (low-fat to low-carbohydrate/ketogenic, and all points between) can be similarly effective for improving body composition, and this allows flexibility with program design. To date, no controlled, inpatient isocaloric diet comparison where protein is matched between groups has reported a clinically meaningful fat loss or thermic advantage to the lower-carbohydrate or ketogenic diet. The collective evidence in this vein invalidates the carbohydrate-insulin hypothesis of obesity.”
No difference between keto (eg high fat low carbs) and high carb, low fat approaches or anywhere inbetween for that matter.
