‘Keto’ or ‘ketosis’ refers to a metabolic state where: 

• Your body burns fat instead of carbohydrates (glucose) for energy. 
• Fat that is stored in the liver is converted into ketones, which replace glucose as an energy source for the brain. 
• Blood sugar levels significantly lower, along with insulin levels (insulin is the hormone that transports glucose from the bloodstream into cells).

The aim of a keto (short for ‘ketogenic’) diet is for the body to undergo ketosis. While the keto diet was initially designed as a treatment for epilepsy, today it is trending for its potential health benefits – particularly weight loss and improved health outcomes for individuals with prediabetes or type 2 diabetes.
