Day 01
Transition to a Fasting State
Your body begins to adjust to reduced calorie intake and glucose stores diminish, setting the stage for fat-burning and cellular benefits. By the 12 to 24-hour mark, your body typically enters a mild state of ketosis, where fat-burning begins.

Day 02
Ketosis
By now, your glucose stores are likely depleted, and your body has shifted to relying entirely on internal fat reserves for energy (ketosis). Unlike traditional fasts, which can cause muscle loss, Prolon is specifically designed to protect lean muscle while supporting fat-burning.

Day 03
Autophagy
Autophagy, typically activated after three days of prolonged fasting, is your body’s natural way of recycling and removing damaged cells, like a deep internal spring cleaning. This process removes waste, repairs damage, and rejuvenates cells, supporting healthier, more efficient function.

Day 04
Cellular Rejuvenation
Your body has reached a heightened state of cellular rejuvenation, with autophagy now in full swing, working to repair and renew your cells at a deeper level. For most, fat burning is also at its peak, providing a consistent and efficient energy source.

Day 05
Renewal and Change
Autophagy has been recycling old cells with younger, high-functioning cell parts, a process known as cellular reprogramming. Now, this transformative renewal resets cell function, supporting lasting benefits.
Days 6&7 - Even though your 5-Day journey is complete, the cleansing and renewal processes continue into Day 7!
