The Fastful Story
The Fastful Story
Fasting is more than just skipping meals. What you eat is just as important as when you eat. That’s why we created a pre-fast diet bar that help keeps you fuller, longer while making sure you’re hitting your daily macro goals. A proper pre-fasting meal can determine your energy and satiety levels during your fast. Our delicious, nutrient-dense fasting bars will reduce fasting difficulty by an average of 45%*. With four delicious flavors to choose from, there is a Fastful bar for every taste. Our bars are high in protein and fiber to help you stay full, while still low in sugar and carbs to prevent energy crashes. What’s more, all of our bars are made without gluten, soy, egg, artificial flavors, GMO’s and are vegetarian friendly. Whether you’re just starting out or have been fasting for years, our pre-fasting bars are the perfect aid for your fasting lifestyle.
