The Prolon fasting mimicking diet is a 5 day program that provides a nutrient rich meal plan of plant based soups, energy bars and snacks, tea and supplements. This meal plan has been scientifically designed and researched for positive changes in metabolic markers, cellular rejuvenation and healthy aging. The foods in the meal plan are low in calories and sugar. It is also high in protein, fats and healthy omega 3 fatty acids.
One of the main ingredients in the meal plan is a bottle of L-Drink each day on days 2-5. This is a liquid mix that contains purified water, vegetable glycerin and calorie free flavouring. The glycerol in the L-Drink is meant to help protect lean body mass during the fasting mimicking diet. It is believed that glycerol acts as an alternate source of glucose (energy) during the fasting mimicking diet and reduces muscle loss.
Valter, the Founder of ProLon, states that his research shows that after three cycles of the fasting mimicking diet, people have found they lose minimal lean body mass. He believes that this is because the glycerol in the L-Drink helps with gluconeogenesis. Glycerol is a natural product of the breakdown of carbohydrates in your body and is used by your body to make glucose for energy.
The calorie level in the L-Drink is also supposed to be low enough to avoid spikes in blood sugar and protect amino acids, the building blocks of proteins. The ingredients in the drink also are said to cooperate to increase hydration and slow down degradation of protein to blood glucose.
