Fasting may be viewed as a means of ONLY reducing weight by some, but this practice has science-backed evidence when it comes to controlling other functions of the body like controlling insulin levels in the body, reducing inflammation and even slowing down aging.
In addition, fasting has also been associated with enhancements in metabolic health and cardiovascular function. Intermittent fasting, specifically, stimulates the body to go into a state referred to as ketosis, where it starts utilizing fat for fuel rather than glucose. This change, apart from helping the body lose fat, also improves mental acuity and concentration, due to the creation of ketones, which are effective sources of fuel for the brain.
