The Fasting Mimicking Diet (FMD) is a five-day low-calorie diet plan designed to trick the body into fasting mode while still consuming certain types and amounts of food. The ProLon FMD, created by Dr. Valter Longo, includes a meal kit with plant-based whole foods, supplements, and an energy drink called the L-Drink, which contains vegetable glycerine. The glycerine in the L-Drink provides an alternate energy source, helping to protect lean body mass and prevent muscle breakdown during the fast. While the FMD can offer health benefits, it is not suitable for everyone, and individuals should consult a doctor or dietitian before starting this or any other diet plan.

What You'll Learn

Glycerine is an energy source
Glycerine is an important component of the ProLon fasting-mimicking diet. ProLon is a five-day, scientifically formulated, low-calorie vegan diet that provides the body with food energy and nutrients to perform basic tasks while remaining in a fasting mode. The diet includes a supplemental energy drink called the L-Drink, which contains glycerine.
The L-Drink is a vegetable glycerin concoction mixed with water or herbal tea. It is consumed on days two through five of the ProLon program. The glycerine in the L-Drink provides the body with an alternate energy source to use instead of lean body mass. This helps protect the body's lean body mass while keeping it in a fasting state. The amount of L-Drink consumed is based on the individual's weight.
The purpose of the glycerine in the L-Drink is to provide an external source of glycerol, which is used for gluconeogenesis, or the production of glucose (energy) from non-carbohydrate substrates like fat and muscle. During fasting, the body naturally produces glycerol. However, if there is not enough glycerol, the body can break down muscle. The L-Drink helps to prevent this by providing a supplemental source of glycerol.
Some people who follow the ProLon diet or other fasting-mimicking diets choose to add glycerine to their regimen to mimic the effects of the L-Drink. This is known as a DIY approach. While it is possible to purchase glycerine at grocery stores, it is important to note that the ProLon diet is based on diligent research and specially formulated ingredients. Attempting to replicate the diet on your own may not provide the same precise composition of nutrients and could impact the overall experience and energy levels during the program.

It helps protect lean body mass
The ProLon Fasting Mimicking Diet (FMD) is a five-day low-calorie diet plan designed to trick your body into fasting mode. It was pioneered by Dr. Valter Longo, a biogerontologist and cell biologist at the University of Southern California. The diet includes a meal program with plant-based whole foods and does not include meat, dairy, gluten, GMOs, or processed foods. It also contains a supplemental energy drink called the L-Drink, made from vegetable glycerine, which is consumed on days two through five.
The purpose of the glycerine in the L-Drink is to provide the body with an alternate energy source to use instead of lean body mass. This helps protect lean body mass while keeping the body in a fasting state. People who are fasting naturally produce glycerol, which is used for gluconeogenesis (the production of glucose/energy from non-carbohydrate substrates like fat and muscle). If there isn't enough glycerol, the body can break down muscle. The L-Drink provides an external source of glycerol, helping to prevent muscle breakdown and protecting lean body mass.
The amount of L-Drink consumed is based on an individual's weight and is mixed with water. While skipping the L-Drink may not interfere with the rejuvenation effects of the diet, it may impact energy levels and increase the risk of losing muscle mass.
Some people attempting a DIY version of the FMD have considered adding glycerine to their regimen to mimic the L-Drink. However, it is important to note that the ProLon FMD is based on extensive research and specially formulated ingredients, and it may be challenging to ensure the same precision with a DIY approach.
Overall, the glycerine in the L-Drink plays a crucial role in protecting lean body mass during the ProLon Fasting Mimicking Diet. It provides an alternative energy source, helping to prevent the breakdown of muscle mass while the body remains in a fasting state.

Glycerine is a component of the L-Drink
Glycerine is an important component of the L-Drink, which is included in the ProLon Fasting Mimicking Diet (FMD). This diet was pioneered by Dr. Valter Longo, a biogerontologist and cell biologist at the University of Southern California. The ProLon FMD is a five-day, scientifically formulated low-calorie vegan diet that aims to trick the body into thinking it is water fasting while still providing essential nutrients and energy.
The L-Drink, which is consumed on days two through five of the ProLon program, is a vegetable glycerin concoction mixed with water or herbal tea. It is designed to provide the body with an alternate energy source, helping to quell hunger and boost energy levels. This is especially important during fasting because the body naturally produces glycerol, which is used for gluconeogenesis, the production of glucose (energy) from non-carbohydrate substrates like fat and muscle.
The amount of L-Drink consumed is proportional to the person's weight, and it is intended to be a one-time-use drink during the diet. While skipping the L-Drink may not interfere with the rejuvenation effects of the diet, it could impact the overall experience and energy levels, and there may be a slightly higher risk of losing muscle mass.
The glycerine in the L-Drink is thought to be important in preventing muscle breakdown during the fasting period. Some people who follow the ProLon FMD choose to add their own glycerine to mimic the L-Drink, especially if they have a frail body composition with low body fat or a compromised metabolism. However, it is important to note that the ProLon FMD is based on extensive research and specially formulated ingredients, and attempting to replicate it with DIY approaches may not be safe or effective.
In conclusion, glycerine is a crucial component of the L-Drink in the ProLon Fasting Mimicking Diet. It provides an external source of glycerol, which helps protect lean body mass, boosts energy, and prevents muscle breakdown during the fasting period. While it is possible to purchase glycerine separately, following the precise ProLon program is recommended for optimal results.
