ProLon is a 5-day Fasting Mimicking Diet (FMD) designed to provide the body with essential nutrients while putting it into a fasting-like state. It’s often marketed for cellular rejuvenation, metabolic health, and weight loss. Here’s an overview specifically regarding its role in weight loss:
What ProLon Is
- Duration: 5 consecutive days.
- Calorie Restriction: About 1,100 calories on Day 1, then ~750 calories per day on Days 2–5.
- Contents: Pre-packaged plant-based meals (soups, nut bars, olives, herbal teas, and a glycerol-based energy drink).
- Goal: Trigger fasting-like cellular responses (e.g., autophagy) without complete food deprivation.
ProLon for Weight Loss: What to Expect
1. Short-Term Weight Loss
- Most users lose 4–8 pounds during the 5-day cycle.
- Weight loss is due to:
- Caloric deficit
- Loss of glycogen and water
- Potential fat loss
 
2. Temporary or Sustainable?
- Water weight tends to return quickly after resuming a normal diet.
- Fat loss can be sustained or enhanced if you follow up with healthy eating and possibly repeat cycles (1/month for a few months).
3. Muscle Preservation
- The diet is designed to reduce lean muscle loss compared to traditional fasting, thanks to the carefully balanced macronutrients.
