There are no meaningful differences in fat loss between diets that vary in carbohydrate and fat content, as long as their protein and calorie content is equal.[1][2]
Nonetheless, certain dietary factors can influence fat loss via their effects on energy expenditure, hunger, and satiety, and thus energy intake. These include ultraprocessed foods, which have been shown to increase ad libitum energy intake;[3] protein, which has the highest thermic effect of food among the macronutrients, helps to preserve muscle during weight loss (and thus preserve basal metabolic rate), and may reduce hunger and prolong satiety;[4] and fiber, which may also reduce hunger and prolong satiety.[5]
