Answer:
a, b, and c are all components that can be altered in fad diets.
Step-by-step explanation:
Fad diets typically follow a pattern of altering the balance of both carbohydrates and fat. They may involve reducing the intake of one type of nutrient and increasing the intake of another type in order to achieve weight loss. For example, some fad diets may emphasize low-carb or high-fat intake, while others may promote low-fat or high-protein intake. The idea behind these diets is to manipulate the balance of macronutrients in the diet in order to achieve a desired outcome, such as weight loss or improved health. However, the effectiveness of these diets and their long-term impact on health is still a matter of scientific debate.
