Diets based on the Fullness Factor have some advantages over Low-Carb diets:
FF-based diets may better encourage the consumption of naturally healthy foods Because many fruits, vegetables, and less processed foods have high Fullness Factors, it may be easier to obtain essential nutrients when on FF-based diets.
FF-based diets offer a larger range of food selections No foods are off limits in FF-based diets. FF-based diets simply encourage you to select the foods that cause you to fill up faster without as many total Calories.
FF-based diets can easily accommodate a vegetarian lifestyle While many meats are good choices for a high-FF diet, it's also relatively easy to create a high-FF diet that doesn't contain animal-based foods.
