Intermittent fasting, also known as intermittent energy restriction, is an umbrella term for various meal timing schedules that cycle between voluntary fasting (or reduced calories intake) and non-fasting over a given period.
Three methods of intermittent fasting are alternate-day fasting, periodic fasting, and daily time-restricted feeding. Intermittent fasting may be similar to a calorie-restriction diet, and has been studied in the 21st century as a practice to possibly reduce the risk of diet-related diseases, such as metabolic syndrome. However, intermittent fasting has been criticised as a fad.
The science concerning intermittent fasting is contested. The American Heart Association (AHA) states that intermittent fasting may produce weight loss, reduce insulin resistance, and lower the risk of cardiometabolic diseases, although its long-term sustainability is unknown. The US National Institute on Aging states that there is insufficient evidence to recommend intermittent fasting and encourages speaking to one’s healthcare provider about the benefits and risks before making any significant changes to one’s eating pattern. A 2019 review concluded that intermittent fasting may help with obesity, insulin resistance, dyslipidemia, hypertension, and inflammation.

The Secret To Look Younger By Applying Intermittent Fasting
Many people go to the beauty salon or a plastic surgeon to look attractive and have a younger appearance. They don’t mind to fetch a lot of money in order to get rid of wrinkles on their face. Exercising helps to look young and so does sleeping. Yet getting old is a natural law that must be experienced. But do you know that intermittent fasting makes you look younger?
Actually, for those who want to stay young, no need to spend too much money on beauty services or expensive beauty products. Simply by applying intermittent fasting.
What happens to our body when we apply intermittent fasting?
Fasting will reduce or temporarily stop physiological processes or metabolism in our body, especially in the digestive tract. Termination of the metabolic process brings four sets of processes that have a major impact on health.
- Limiting the amount of food that enters the digestive tract.
- Lowering the intensity of the digestive system.
- With the decrease in the intensity of the work, the presence of toxins from the body, both endotoxins (toxins from the body itself) and exotoxins (toxins from outside the body) also decrease.
- The reduction of ingredients that must be digested will also make our bodies not force themselves to release hormones and digestive enzymes on a large scale.
Imagine otherwise if we do not fast? To be sure all foods that enter the body must be digested. Inevitably, we will force our digestive organs to work harder.
Already a common understanding among experts, so-called youth is basically an inhibited process of premature aging. Our body starts to age as early as the age of 25 even we do not feel it.
What Is The Scientific Or Evidence-Based That Intermittent Fasting Makes You Look Younger?
Among some of the most famous theories of aging is the free radical theory that emerged in the 1950s. The free radical theory of aging states that organism age because cells accumulate free radical damage over time. A free radical is any atom or molecule that has a single unpaired electron in an outer shell.
The free radical theory reads, “If our bodies have many free radicals, then free radicals will damage the cell wall, destruction of the cell wall will accelerate aging.”
Fasting is powerful in protecting the cell wall. Cell walls can be maintained because free radicals are absent or reduced by fasting. So intermittent will slow down aging.
Scientists have examined the way fasting affects cellular and mitochondrial function and longevity. They have found the cells in our body react to fasting in much the same way as they do to exercise. When the cells under stress – exercise or fasting – the reaction creates changes at the cellular level that helps extend our lifespan. See HealthyHappyWomenAfter40.com for the rest of the article.
