Dietary macronutrient composition and its effect on 24-hour substrate oxidation: A study of diurnal variations in carbohydrate and fat intake

In recent times, the complexity of food styles and meal content has increased, leading to significant variations in macronutrient composition between meals. This phenomenon has coincided with a rise in obesity rates. We aimed to determine whether a large variation in macronutrient composition between meals results in reduced fat oxidation.
