Best Exogenous Ketones For Weight Loss And Benefits


A ketogenic diet has proven its efficiency in trimming down body fat by using it as a primary source of energy (1). 

Majority of the fitness influencers are using it to stay in perfect body shape. But the keto diet isn’t as easy as it sounds, it demands you to eat the right food and includes a lot of discipline. 

Normally, people take 4-5 days to get into the state of ketosis and the transition period of ketosis might seem like torture to many. 

One way you can speed up the process of ketosis is through supplementing with exogenous ketones. We are going to discuss the best exogenous ketone supplements for weight loss in a short while, before that, we need to understand some basics about these external ketones. 

What Are Exogenous Ketones:

When you get yourself into ketosis, your body starts producing endogenous ketones to start breaking stored fats as a primary source of fuel. But the production of endogenous ketones depends on numerous factors like hormones, body type, ultra-low-carb food, regular exercise, etc. 

Exogenous ketones are the ketones found in a food supplement. Beta-hydroxybutyrate ketone is the primary content of Exogenous ketones supplements. 

Exogenous ketones are broadly available in two types: 

  • Ketone salts 
  • Ketone esters

Ketone salts: These are the most common exogenous ketones available in supplements form. These ketones are bound to a salt, generally potassium, calcium or magnesium. 

Study conducted on the changes in blood ketones after supplementing with ketone salt, blood ketone levels of participants boosted by over 300%

Ketone Ester: These supplements are typically available in liquid form. This beta-hydroxybutyrate ketone is linked to esters. 

How To Use Exogenous Ketones

Exogenous ketones are an incredible add-on to your ketogenic diet, but it’s also important to know the right timing of supplementing with exogenous ketones. 

Supplementing at right time can accelerate the fat loss. Let’s understand how to use exogenous ketones in the right way. 

  • Best time to consume exogenous salts or ester is when your blood is low in ketones
  • Everyone’s body acts differently while in ketosis, and the best way to know your best time is by checking your blood ketones levels

  • Its recommended to check your ketone levels after intense workout sessions, that’s when your body is craving for energy and supplementing with exogenous ketones can speed-up the fat burning.
  • You can supplement yourself with ketone salts when you feel low in energy levels, the majority of people experience low energy while in the keto transition period. 
  • Use these supplements to rapidly get yourself into a state of ketosis

Exogenous Ketones Benefits For Weight Loss

Your main focus should be on fat loss instead of weight loss.

While being on the ketogenic diet, you force your body to metabolize stored fats as a primary source of fuel. Exogenous ketone salts may work as a catalyst to initiate stronger ketosis.

Let’s have a look at exogenous ketones benefits for weight loss:

Being is a society where people are obsessed with food, staying in a ketogenic diet might seem impossible for many. 

There are going to be instances when you will be forced to eat high-carb food items. These exogenous ketone supplements will help in quickly getting back into the state os ketosis. 

3# Drop-in appetite: 

People in a ketogenic diet experience decreased appetite, this can be linked to faster weight loss. 

A study found fascinating changes in hunger pattern. Participants supplemented with ketone esters experienced 50% less hunger after an overnight fast than those drinking a sugary beverage.  

4# Mental clarity and energy

Ketones are directly responsible for energy production by metabolizing stored fat. Supplementing when your body is low in ketones will result in feeding your body with the required energy to do your daily stuff.

How to check your blood ketone levels? 

It’s necessary to check the effectiveness of your keto supplements, keeping an eye on your blood ketone levels is the best bet. There are three ways to check your blood ketone levels.

Ketone strips: Although one of the cheapest way to test the blood ketone levels, it’s not very accurate. If your intention is to have a rough idea about keto progress then ketone strips can work for you.

Breathalyzer: It’s a one-time investment. breath analyzers are built specifically to read the body ketone levels. Once you invest in it, you can track your progress ten times a day. Its much more accurate then ketone urine strip.

Ketone Meter: The most accurate method of checking the blood ketone levels. The only drawback is the cost of test strips, their cost might bother many people.
