Energy balance

High-carbohydrate overfeeding increases 24-hour energy expenditure (EE) more than high-fat or fasting diets, despite being associated with lower lipid oxidation.

If you are overfeeding, a high-carbohydrate diet may result in higher total energy expenditure than a high-fat diet. This does not mean high-carb is better for weight loss, but it does show that the body burns more total energy when processing high carbs in an overfed state.
