Brew the tea in hot water – covered – for 3 to 5 minutes. Then mix all the ingredients with a mixer or handheld milk frother until frothy.
Do you need an example? One of the earliest studies of fasting reported that rats increased lifespan by up to 80% when given a fasting schedule that included food only every other day. In a study of worms, a fasting diet increased lifespan by 40%; In another, male mice participating in a two-day fasting program, they observed an increase in longevity.
OK, but rats and worms aren’t humans. Well, there is substantial evidence that fasting increases life expectancy in humans too. To start with, it is known to prevent many age-related diseases, including the leading causes of death. There are many theories as to why fasting is so beneficial for lifespan. You are dealing with “blue zones” like the one on the island of Okinawa. The isolated population there usually maintains an intermittent fasting schedule and has extremely low obesity and diabetes rates and extreme longevity.
As we already know, extended fasting produces ketones; Well, ketones also regulate the expression of specific molecules and proteins that play a known role in aging. Some examples of this are NAD + and sirtuins. You may have heard of NAD + because there are a growing number of supplements that are said to promote NAD + and then promote a healthier cell aging process. How do you ask NAD + levels decrease with age, and as explained in an article published in Trends in Cellular Biology, this can be “an Achilles’ heel causing defects in core and mitochondrial functions and leading to many age-related pathologies”.
It is believed that restoring NAD + levels, especially if they decrease with age, can alleviate age-related problems and counteract age-related diseases. NAD + supports cellular energy and helps you to maintain healthy DNA. However, this also happens through the activation of sirtuins. I am at risk of delving too deeply into the science of aging, but sirtuins are a class of proteins found in all types of living organisms – from yeasts to bacteria to mammals. In humans, sirtuins play a key role in the body’s cellular response to stressors, including oxidative stress and DNA damage. Some studies have suggested the idea that sirtuins could play a direct role in extending lifespan. The good news is that NAD + supplementation isn’t the only way to increase sirtuin levels. In fact, physical activity and dietary changes – including fasting and the ketogenic diet – have been shown to increase sirtuins. Even certain compounds like curcumin are being studied for their ability to increase sirtuin levels.
Another path to longevity that researchers are exploring is mTOR. Increased mTOR is associated with accelerated aging and age-related diseases. The mTOR pathway is particularly stimulated by protein consumption. Both fasting and fasting-mimicking diets such as the ketogenic diet have been shown to be beneficial in balancing mTOR.
Intermittent fasting has also been shown to stimulate mitophagy, which is essentially just the autophagy of the mitochondria. Finally, fasting has been shown to also inhibit pathways that make proteins and pause to create new material so the body can conserve energy and resources while cleaning the house. You don’t want your cells to divide and replicate all the time as this is associated with an increase in oxidative stress. Research has also confirmed that if you snack continuously, overeat, or lead a sedentary lifestyle, these beneficial pathways go unused or even suppressed. For this reason, it seems overwhelmingly beneficial to go without food regardless of the specific protocol.
