Formulated to stay below the body's nutrient-sensing pathways, so you can maintain a fasting state while enjoying a satisfying snack or meal.
Helps your body produce ketones and burn fat for fuel — comparable to a water-only fast — without the hunger.
Plant-based proteins, healthy fats, prebiotic fiber and 21 vitamins & minerals in every sachet.
Built on 25+ years of fasting and longevity research from USC and L-Nutra.
The Fasting Shake is based on the same scientific principles behind our patented Fasting Mimicking Diet. Its precise nutrient composition is designed to stay below your body's nutrient-sensing pathways while supplying plant-based protein and healthy fats to keep you nourished. The patented formulation is as effective as water-only fasting in reducing glucose levels and increasing ketone bodies — so you get the benefits of fasting without hunger.
