What is a Fasting Mimicking Diet®

The Fasting Mimicking Diet®, or FMD®, is the first meal programme made of healthy natural ingredients that you consume for five days, during which your body does not recognise that it is eating, and therefore remains in a fasting mode. In simple terms, it is fasting with food!

This nutritional breakthrough was scientifically developed and clinically tested at the Longevity Institute at the University of Southern California. Led by Dr. Valter Longo, the USC Longevity Institute unites multidisciplinary ageing research approaches.

Benefits of the Fasting Mimicking Diet®

Types of fasting

Fasting is generally defined as the abstinence from or limitation of food, drink or both. From a physiological and metabolic perspective, each type of fasting leads to different health effects, depending on the type and duration of the fast. There are three main categories of fasting: time restricted feeding; intermittent fasting; and short term and prolonged or periodic fasting.

1. Time Restricted Eating (TRE)

Time Restricted Eating is when a person ingests food only at certain times during the day, and refrains from eating for the rest of the time. A 12 hours per day no-food intake period would fall into this category.

This diet is mostly positioned for weight loss and to not overwhelm the body with continuous food intake.

2. Intermittent Fasting (IF), Alternate Day Fasting (ADF) and Intermittent Energy Restriction (IER)

Intermittent fasting, alternate day fasting, and intermittent energy restriction are other popular types of fasting behaviours. The most common, intermittent fasting, is called the 5:2 diet which involves fasting on less than 500 calories for women or less than 600 calories for men for two non-consecutive days a week. For example, fasting on a Monday and Thursday each week. This method is mainly used for weight loss induced metabolic effects due to the two days of calorie restriction per week.

Note: Intermittent fasting could induce circadian rhythm and mood fluctuations, and did not prove to improve some blood metrics such as IGF-1.

3. Short Term (ST) and Prolonged or Periodic Fasting (PF)

Short term and prolonged, or periodic fasting, defines periods of consecutive days of fasting. ST is less than 3 days and PF is 3 or more than days. Periodic fasting is the only fasting regimen that “stresses” the body enough to stimulate a protectionist and rejuvenation mode that the body employs to survive and thrive.

ProLon® is the first and only Periodic Fasting Mimicking Diet and is scientifically developed, and clinically proven, to induce the protectionist and rejuvenation mode. No other meal programme is capable of inducing these benefits.
