Does a ketogenic diet result in greater energy expenditure? | Peter Attia & Layne Norton

Partially SupportedStudies in controlled environments show no significant differences in body fat loss between low-carb and low-fat diets when calories and protein are controlled.

Partially SupportedAn isocaloric swap between a standard American diet and a ketogenic diet showed a difference of no more than 50 to 150 calories in energy expenditure.

Not SupportedThe carbohydrate-insulin model may work for short-term weight loss with a slight increase in energy expenditure, and is potentially better with a ketogenic diet than a low-fat diet, but is unlikely to be effective for weight maintenance over a lifetime.

Partially SupportedBody fat loss can be achieved with low-carb, low-fat, or balanced diets if calories and protein are equated.
