The Science of
Fasting Mimicking®


Your cells usually feed on the carbohydrates, protein, and fat you eat.


Now imagine you eat a nutrition bar that provides good fats from nuts as they replace most carbs and protein. As a result, you may trick your cells to enter a semi-fasting state since they are mostly receiving fats and not the other nutrients. We call this process a fasting mimicking effect!

Fast Bar™ is a nutrition bar that nourishes your body with a premium blend of nuts if you are into intermittent fasting, or are on the go, or simply want to enjoy a delicious snack.

Types of Intermittent Fasting

Intermittent Fasting consists of a Fast On/Fast Off approach, but it may be risky when you skip meals.

TIME-RESTRICTED EATING (TRE) - you restrict the hours you eat in a day.

WHOLE DAY FASTING - you don't eat anything in one day once a week.

ALTERNATE DAY FASTING - you eat food one day and the next you don't.

SHORT-TERM INTERMITTENT FASTING - you fast with no food for 2 or 3 consecutive days. Like the 5:2 Diet (2 days of fasting and 5 days of regular eating).

Prolonged Fasting

PROLONGED FASTING is 4 or more consecutive days of fasting in a week. Your body starts autophagy (a process where your cells start eating themselves) on day 4 that triggers a cellular regeneration and the slowing of the markers of aging. ProLon, the 5-Day Fasting Mimicking Diet (FMD)™ has been clinically tested to support the benefits of Fasting with Food™.

Learn more about the science behind the Fasting Mimicking Diet (FMD)®, the foundation of Fast Bar™

The FMD patented nutrition technology allows the body to remain under a fasting state, which triggers a set of protective measures that the body developed as part of natural selection when food was scarce and not easy to find and store. This process pushes the body to become more efficient in its performance, rejuvenate its cells, and thrive under such circumstances. When tested in mice, Fasting Mimicking Diets® increased their median health span by a striking 11%, and in randomized human trials the FMD normalized some metabolic health metrics that are compatible with aging and health span.

Skipping breakfast may not be good for you

Scientific research is finding that skipping breakfast may pose risks to cardiovascular health such as the development of atherosclerosis, or hardening of the vessels in your body. Several studies have been published by the Journal of the American College of Cardiology on this topic.

Restricting the hours you eat in a day while keeping check on your biological clock may lead to better health

In time-restricted eating (TRE) individuals can compress time for meals ideally up to 12 hours according to the Longevity Diet Book by Valter Longo PhD. The synergistic interactions of the circadian oscillator in combination with fasting/feeding (TRE) signals may ensure that the anabolic (buildup of energy) and catabolic (release of energy) phases of metabolism are coordinated in harmony and regulated with activity and rest cycles This rhythm of eating and fasting daily can enhance nutrient intake that may help optimize the health of the individual to promote longevity.
