What is Intermittent Fasting?

Intermittent fasting is a tool many individuals use to lose weight and improve their overall health. It is a method that many individuals use as part of a total weight loss plan or program.

Intermittent fasting has been popularized in many popular diet books. This concept is based on the idea that partial fasts and lower calorie diets or calorie restriction may help individuals maintain a healthier weight. 

Intermittent fasting works by alternating periods of fasting with periods of eating normally. Fasting may include periods of consuming relatively little or periods of consuming a very selective diet. Fasting may include eating water or fruits and vegetables, while normal eating periods may include a limited diet or healthy eating program.

Research suggests that intermittent fasting may help improve the health and total length of life or longevity of humans. Intermittent fasting may have health benefits that are similar to those of long-term caloric restriction. Caloric restriction involves reducing the total amount of calories that one eats. 

Caloric restriction has been shown to improve life span. Intermittent fasting is often referred to as dietary energy restriction, as has caloric restriction. Studies on intermittent fasting and caloric restriction have been carried out for more than a decade. They suggest that fasting one day out of three results in optimal life spans without retardation in growth, at least among animals.

What is good for animals may be good for humans. Among the health benefits that may be realized by fasting include reduced glucose and insulin levels, and reduced stress levels. Cardiovascular and brain function may also improve as a result of intermittent fasting. Blood pressure may also normalize, as may cognitive function. The idea is that by putting less strain on the digestive system, the body has more energy to place on other systems in the body.
