Which Intermittent Fasting Diet is Best?

ProLon may be the better choice if you want a simple prepackaged solution, are vegan/vegetarian, or want something scientifically formulated. However, the Bone Broth Diet gives you more control over your menu and may suit low-carb diets better.
It also costs much less than buying multiple ProLon kits.
Keep in mind that these rapid weight loss diets are not meant for long-term use. Maintaining weight loss may require transitioning to sustainable, everyday healthy eating habits with or without intermittent fasting. Consult your healthcare provider before starting any new diet.
