The Ins and Outs of Keto Diet

According to World Health Organization, about 1 Billion people in the world will be obese by 2030. 

Obesity continues to remain a major worldwide health problem with a mortality rate as high as 2.8 million per year. The majority of chronic diseases like diabetes, hypertension, and heart disease are largely related to obesity. The main reason is usually an unhealthy lifestyle and poor dietary habits. 

There have been many tailored diets for weight loss, the most recent hype is Keto Diet. So let us take a closer look into the benefits and risks of being on the keto diet and is it the right choice for you.


What is Keto Diet?

A ketogenic diet primarily consists of high fats (55-60%), moderate proteins (35%), and very low carbohydrates (5-10%). 


How Does it Work?

Basically, sugars are the primary source of energy production in the body. When the body is deprived of carbohydrates (sugars) due to reducing intake to less than 50g per day, insulin secretion is reduced and the body enters a catabolic (breakdown) state. When there is low carbohydrate your liver starts producing glucose in the form of lactic acid, glycerol, and amino acids to provide the body with its sugar need, but as the sugar level continues to decrease liver cannot keep up with the demand of the glucose, that is when ketogenesis starts (breakdown of fats). It begins in order to provide an alternate source of energy in the form of ketone bodies. Ketone bodies replace glucose as a primary source of energy. This metabolic state is referred to as "nutritional ketosis." As long as you deprive yourself of carbohydrates, the metabolism remains in the ketotic state. The nutritional ketosis state is considered quite safe, as ketone bodies are produced in small concentrations without any alterations in blood pH. It greatly differs from ketoacidosis, a life-threatening condition where ketone bodies are produced in extremely larger concentrations, altering blood pH to an acidotic state.
