Satisfy Hunger, Stay in Fasting Mode
How much weight will I lose after the program?
Based on clinical studies and real customer experiences, the average weight loss during the 5-day program is about 2.5 kg. What's unique about Prolon is that the weight lost is primarily fat, while muscle mass is preserved.
Note: Results may vary depending on body type and other individual factors.
How many times can I repeat the program?
You can repeat the program once a month. Do Prolon for 5 days, then take a 25-day break—during which you can eat healthy and exercise—before starting the next cycle. This structure supports long-term fat loss and cellular benefits.
What happens to my body during the fasting mimicking program?
While following the program, your body enters a fasting state even though you're eating. This triggers fat burning, cellular cleanup (autophagy), and supports stem cell renewal—all while receiving the nutrients you need. Many people report feeling lighter, more energized, and more in control of cravings.
Can I drink coffee during the program?
Yes, you're allowed one cup of black coffee per day—with no sugar, sweeteners, or creamers. This helps preserve the benefits of the fasting state while still enjoying your morning routine.
What is the daily caloric intake during Prolon?
- Day 1: ~1,100 calories
- Days 2–5: ~700 to 800 calories/day
This calorie structure is carefully designed to mimic fasting, supporting weight loss and rejuvenation without complete food restriction.
