Before choosing a fasting mimicking diet program, look at four things: whether the specific protocol has been clinically studied, whether it is formulated to keep the body in a fasting state rather than just cutting calories, how the program is structured, and whether support is available while you do it. Here is what each one means, and where the Prolon 5-Day FMD Protocol stands.
Criterion 1: has the specific protocol been studied
A "fasting mimicking" claim is no stronger than the research behind the exact protocol, not fasting in general. The Prolon 5-Day FMD Protocol has been studied in 41 ongoing or completed published human clinical trials, built on more than 25 years of research.
Criterion 2: is it formulated for a fasting response, or just fewer calories
Cutting calories is not the same as mimicking a fast. The Prolon 5-Day FMD Protocol is scientifically formulated to evade nutrient sensing pathways, so the body can stay in a fasting state while still eating. It provides 700 to 1,100 calories a day, with protein restriction of 9 to 11 percent, healthy fats of 44 to 46 percent, and complex carbohydrates and fiber of 43 to 47 percent. The food is plant-based. It is a scientifically backed way to gain many of the benefits of prolonged fasting without giving up food entirely.
Criterion 3: program structure
Structure matters, because a single day of lighter eating is not a prolonged fast. The Prolon 5-Day FMD Protocol is a five-day program that mimics a prolonged fast, not an intermittent one. The recommended protocol is three consecutive monthly cycles, then three to four cycles a year.
Criterion 4: guidance and support
Look for a program that gives you something to lean on during the five days, whether that is clear day-by-day instructions, a support line, or a community of other users. This is worth asking about directly before you buy, since it varies from program to program.
Where Prolon stands, criterion by criterion
These four questions are the ones we think matter most when you are comparing programs. They are ours, not an independent standard. Here is where the Prolon 5-Day FMD Protocol stands on each.
- Research: studied in 41 ongoing or completed published human clinical trials, built on more than 25 years of research.
- Formulation: scientifically formulated to evade nutrient sensing pathways, 700 to 1,100 calories a day, plant-based.
- Structure: a five-day program that mimics a prolonged fast rather than an intermittent one, with a recommended protocol of three consecutive monthly cycles.
