Fastful Intermittent Daily Fasting Plan

Intermittent Fasting ( Time Restricted Eating ) means consuming food during a limited window of time per day, typically 4 to 12 hours in duration, and then going without food the remainder of the day.

      Fastful® is the first nutrition bar to feature micellar casein, a natural dairy protein which provides your body with the slowest digesting protein source on earth.
  • Chia Seeds
      Chia Seeds are packed with antioxidants, fiber, and omega-3 fatty acids. They help maintain hydration and are incredibly satiating.
  • Flax Seeds
      Flax Seeds are small but powerful. They’re loaded with omega-3 fats, fiber, and other essential nutrients.
