![]() For example, they help trigger the repair of the damaged molecules in the body, and can reduce inflammation and improve glucose regulation. When there are increased levels of ketones in the body through ketogenesis, they not only serve as a fuel for the body, but also have effects on other functions. Ketogenesis is the critical mechanism in intermittent fasting by which weight loss is achieved. In this state, the body has undergone ketosis and is called keto-adapted. Intermittent fasting is known to increase metabolism, and instead of relying on glucose as an energy source, it uses ketones stored in fat to fuel the brain and body. ![]() Metabolism is a process that describes a series of chemical reactions in the body, which break down food into energy. For example, late-night snacking causes a rise in insulin and the release of energy when at that time, the body is more suited to be in a rested state to optimise recovery. Intermittent fasting can help the body to rest and recover, improve gut function and help the body to become in sync with its circadian rhythm. Our cells then use glucose as a vital energy source or store it as glycogen, ready to be used when needed. When our pancreas secretes insulin, it acts as a messenger to the cells in our body to take in sugar (i.e. Insulin is a hormone secreted by the pancreas. Insulin is an example of a hormone that follows a circadian rhythm, whereby insulin sensitivity decreases throughout the day and into the night. ![]() What are the Benefits of Intermittent Fasting? Circadian Rhythm Function It is thought that our feeding times help control our natural body clock, which is why the times we eat can play an essential role in our overall health. Our bodies have a biological clock, also known as a ‘circadian rhythm’, which allows processes in our body to occur at certain times during the day or night, according to when our bodies work best. ‘Circadian fasting’ is based on eating during the light hours and fasting in the dark.This fasting regimen is known as the 5:2 diet and has gained popularity due to its reported health benefits. ‘Time-restricted feeding’ allows some energy consumption on fasting days which tend to be held on two days a week, with 16-hour fasting times and an 8-hour break.‘Complete alternate-day fasting’ involves restricting all energy-containing food and drinks on alternate days.Generally, we can categorise intermittent fasting into three main types: complete alternate-day fasting, time-restricted feeding and whole day fasts. These periods can vary in length and structure. Intermittent fasting involves abstaining from food and certain drinks for a period of time to improve health. In the modern era, fasting has become popularised as a form of a diet for losing weight and staying healthy. For example, Muslims fast in the month of Ramadan, Christians will fast in the month of Lent, Hindus will fast during Shravan Mahina, Jains will fast during the festival of Paryushan, etc. Introduction What is Intermittent Fasting?įasts are generally represented in religion.
