Why fasting is healthy

Based on this, researchers from the University of Alabama conducted a study with a small group of obese men with prediabetes. They compared a form of intermittent fasting called "early time-restricted feeding," where all meals were fit into an early eight-hour period of the day 7 am to 3 pm ,or spread out over 12 hours between 7 am and 7 pm.

Both groups maintained their weight did not gain or lose but after five weeks, the eight-hours group had dramatically lower insulin levels and significantly improved insulin sensitivity, as well as significantly lower blood pressure.

The best part? The eight-hours group also had significantly decreased appetite. But why does simply changing the timing of our meals to allow for fasting make a difference in our body? Fasting is evolutionarily embedded within our physiology, triggering several essential cellular functions. Flipping the switch from a fed to fasting state does more than help us burn calories and lose weight. The researchers combed through dozens of animal and human studies to explain how simple fasting improves metabolism, lowering blood sugar; lessens inflammation, which improves a range of health issues from arthritic pain to asthma; and even helps clear out toxins and damaged cells, which lowers risk for cancer and enhances brain function.

The article is deep, but worth a read! I was very curious about this, so I asked the opinion of metabolic expert Dr. For instance, you might try eating only during an eight-hour period each day and fast for the remainder. Or you might choose to eat only one meal a day two days a week. There are many different intermittent fasting schedules. Mattson says that after hours without food, the body exhausts its sugar stores and starts burning fat.

He refers to this as metabolic switching. Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat. Once you get his or her go-ahead, the actual practice is simple. You can pick a daily approach , which restricts daily eating to one six- to eight-hour period each day. Williams is a fan of the daily regimen: She says most people find it easy to stick with this pattern over the long term.

Another, known as the approach , involves eating regularly five days a week. For the other two days, you limit yourself to one — calorie meal. An example would be if you chose to eat normally on every day of the week except Mondays and Thursdays, which would be your one-meal days. Longer periods without food, such as 24, 36, 48 and hour fasting periods, are not necessarily better for you and may be dangerous. Going too long without eating might actually encourage your body to start storing more fat in response to starvation.

But, he observes, research subjects who make it through the adjustment period tend to stick with the plan, because they notice they feel better. But what Williams likes about intermittent fasting is that it allows for a range of different foods to be eaten — and enjoyed.

She adds that eating with others and sharing the mealtime experience adds satisfaction and supports good health. This approach puts the body through short and intensive therapy.

The intermittent calorie restriction approach also reminds us that we do not need to consume constantly. When we do consume we can choose wisely and continue normal activities and exercise with reduced fuel. Periodic Fasting with Fasting Mimicking Diets This means limiting calorie intake for three to five days, prompting the cells to deplete glycogen stores and begin ketosis.

A specific five-day calorie-limited diet around 1, calories per day is sufficient to mimic fasting without depleting nutrients. It is speculated that this method is superior to the two-day fast, allowing the body to enter ketosis and begin a true cleanse.

Health Benefits of Fasting Although fasting can be challenging and sometimes uncomfortable, the mental and physical benefits can: Boost cognitive performance Protect from obesity and associated chronic diseases Reduce inflammation Improve overall fitness Support weight loss Decrease the risk of metabolic diseases Benefit cancer patients — A recent study with mice and cancer showed that fasting during chemotherapy jump-starts the immune system and exposes the cancer cells.

Ridding the body of old, toxic cells and replacing with new, healthy ones may be just the answer. Traditionally, cancer patients have been told to increase nutrients and caloric intake while undergoing chemotherapy treatments but this approach might now be under review.
