Good reset. Not a weight loss program and I need to loose weight.

Hi Susan, thank you so much for sharing your experience with us! We're glad to hear that the program served as a good reset, and we appreciate you giving the program a try.
While some participants may experience weight loss as a benefit, it is not the primary goal of the 5-Day Fasting Mimicking Diet (FMD). Weight loss can be a positive side effect of the metabolic changes supported by the program, but the FMD was originally developed by Dr. Valter Longo to support the body's natural cellular rejuvenation processes, including autophagy, while promoting overall metabolic health and healthy aging. Every person's body responds differently, and individual results can vary based on a variety of factors.
We truly appreciate your feedback and wish you all the best on your continued health journey. If there’s ever anything we can do to support you, please don’t hesitate to reach out!

Great personnel; food, not so much
The support people were great. The food? It was very repetitive, and, for me, caused some gastric stress. the food was not a sustainable feature for me, especially long term. I also don’t feel the plan addresses the social aspect of eating (a meal)—especially with others. It’s hard to connect with your coworkers, and especially your spouse and/or family over a meal if you’re fasting.

Hi Kevin,
Thank you so much for sharing your feedback! We’re glad to hear that our support team was able to provide you with a positive experience, and we truly appreciate your honesty regarding the food and social aspects of the program.
We understand that fasting can make social meals and long-term adherence challenging, and we’ve shared your feedback with our product development team to be considered for future improvements.
Regarding the gastric stress, Prolon is a plant-based, fiber-rich program, and any significant dietary change, including increased fiber, can sometimes lead to mild bloating, cramping, gassiness, constipation, or diarrhea.
Pre-clinical studies with fasting-mimicking programs have also shown positive changes in the microbiome, such as reduced intestinal inflammation and the growth of beneficial bacteria like Lactobacillaceae and Bifidobacteriaceae, which may contribute to these temporary symptoms. Typically, these effects are short-lived and resolve once you return to your regular diet.
Prolon was designed to mitigate some of the negative side effects of long water fasting, like dehydration, muscle loss, hypoglycemia, and nutrient deficiencies, while still supporting the benefits of fasting, including autophagy.
The program provides a carefully formulated combination of micro- and macronutrients to nourish the body during this rejuvenating process. Some key ingredients include:
Nuts: Heart-healthy monounsaturated fats
Olives: Monounsaturated fats and antioxidants
Flax seeds: Omega-3s, fiber, and essential nutrients
Vegetables: Vitamins, minerals, and fiber
Lentils: Protein, fiber, and nutrients
Spices: Flavor plus potential anti-inflammatory benefits
Prebiotic fiber: Supports gut health and beneficial bacteria growth
