Energy balance

The thermic effect of food (TEF) for a carbohydrate load is significantly higher in individuals adapted to a high-carbohydrate diet compared to those adapted to a high-fat diet.

Your body burns more energy processing carbs if you are used to eating them. If you switch to a high-carb diet, your TEF increases, which might slightly aid in energy expenditure, but this is a minor factor compared to total intake.

GoodSupportsHIGH confidence
The thermic effect of the CHO load was 6.5 +/- 0.4% on the mixed diet, and 5.2 +/- 0.5% on the high-fat, 8.6 +/- 0.4% on the high-CHO diet.
