I ate 12 almonds, 1 bowl of soup, and 4 olives every day for a week.


The Fast Mimicking Diet was developed by longevity researcher Dr. Valter Longo who serves as the director of the USC Longevity Institute.

Prolon, a company owned by Dr. Longo (although he claims he does not receive financial benefit from the company), sells “fasting kits” which allow you to easily take part in a 5-day diet program by consuming their “proprietary nut bars and soup blends”. The company describes the diet as so on their website:

“…5-day dietary program that nourishes your body while promoting regenerative and rejuvenating changes, including effects on a wide range of markers that contribute to aging, such as cholesterol, inflammation, and fasting glucose.”

The goal of the diet is to place you in the metabolic state of fasting while mitigating the physical and psychological stress that fasting places on the body. The benefits of fasting and the studies conducted on the FMD in particular are out of the scope of this post but I’ll add some links at the end if you are interested.

Last year, I put myself through a 5-day water only fast and it was absolute hell. I had terrible heartburn, crazy mood swings, and crippling fatigue and muscle weakness. Consuming something, even if it was only 800 calories, sounded far better than going 5 days on an empty stomach. I didn’t want to spend upwards of $200 on a FMD kit from Prolon so I made one myself following the same parameters outlined in the studies conducted.

It worked out well. I saved a lot of money and was able to find a few snacks and food options that I’ve adopted into my normal diet.
