Fad diets generally support guidelines for which type of foods?

Fad diets often promote the idea of consuming foods that are perceived as having better nutritional quality, aiming for weight loss or health improvements. These diets typically emphasize whole foods such as fruits, vegetables, lean proteins, whole grains, and healthy fats, while often restricting or demonizing certain food groups. The premise behind supporting better nutritional quality is that these foods generally provide essential vitamins, minerals, and other nutrients that contribute to overall health.

In contrast, the other options reflect types of foods that are typically considered less beneficial based on nutritional guidelines. High caloric foods, processed foods, and high sugar foods do not align with the principles of nutritious eating promoted by many fad diets. Such diets focus less on these foods, as they tend to be associated with weight gain, nutrient deficiencies, or increased risk of chronic diseases. Hence, the focus on better nutritional quality foods aligns with the overall objectives of many fad diets.
