Science of intermittent fasting 1

Intermittent fasting, also called IF, has become a popular method for losing weight amongst other mind blowing benefits. It is also said to increase energy levels, increase motivation and endurance, and improve cognitive function.

There are many different  Types of intermittent fasting, each with individual variation in the duration of fasting; some for hours, others for days.

It has become an extremely popular topic in the scientific community because of all the potential benefits discovered on physical health and health, the benefits of intermittent fasting are vast.

Fasting gets a bad name, but the fasting technique is based on real science, especially intermittent fasting. Many people think that someone who is fasting has an eating disorder, but nothing could be further from the truth.

Although intermittent fasting seems to offer some promising benefits, it may not be suitable for everyone, man or a woman. And, as things stand, more and more research is being done on intermittent fasting in rats than in humans.

The truth is that in today's society we eat too much and too often. Our bodies are very precise mechanisms that, to function properly, will take care of us far beyond our imagination.

The problem is that, historically, for thousands and thousands of years, we were a species with few food resources and we worked hard every day for the bites we had.

IF has an intuitive meaning. The food we eat is broken down by the enzymes in our gut and eventually becomes molecules in our bloodstream. Carbohydrates, especially sugars and refined grains (such as white flour and rice), break down quickly into sugar, which our cells use for their energy. If our cells do not use everything, we store them in our fat cells as fat. But sugar can only enter our cells with insulin, a hormone produced in the pancreas. Insulin provides sugar to the fat cells and keeps it there.

When the body is running normally, it is drawing on glucose stored in the liver and muscles for energy. But once those stores are used up, it goes into a state called ketosis. The liver breaks down fat and produces ketones, which can be used by the body for energy.
"Ketones have a lot of different signaling properties," explained Associate Professor Leonie Heilbronn, an obesity and metabolism researcher at the University of Adelaide.
There is evidence that ketones can reduce appetite, and they reduce oxidative stress and inflammation levels. They are not just used for energy but they have got a lot of beneficial effects.

It is unclear that intermittent fasting is superior to other weight loss methods in regards to amount of weight loss, biological changes, compliance rates, and decreased appetite. Intermittent fasting falls into the category of calorie restriction which has well researched science behind it as a way to increase lifespan.

Proper fasting intermittently can help to eliminate many problems caused from overeating and sitting around such as obesity. Intermittent Fasting is a natural part of the human life cycle.

Most people have fasted unknowingly throughout their lifetimes by eating an early dinner and skipping breakfast the next day. A more structured approaches may work well for some people.

The science behind intermittent fasting, being so vast, will be continued in a subsequent post.
