Do exogenous ketone supplements do anything for weight loss? Or should they only be used to aid the transition into the keto diet?
Exogenous Ketones supplements
No.
Also no.
Eat a ketogenic diet and allow your body to naturally produce and burn ketones for energy.
Exogenous ketones have their place in the treatment of certain conditions, but for most people they merely cause expensive urine. One of the major benefits of the ketogenic diet is the lowering of insulin, because of the reduction in carbohydrate intake, and this is a benefit exogenous ketones simply cannot provide.
Taking exogenous ketones would prevent your liver from going after your own body fat when your insulin is low. Ketones themselves do not burn body fat, they are byproducts of body fat when your liver-muscle-fat signaling axis start the adrenal processes (catecholamines) to break down body fat (lipolysis) to get some fuel (ketones). So if you place exogenous ketones into mix, your body will alternately use them for fuel instead, and bypass lipolysis or excrete them in the urine because your not fully adapted to use all them ketones for fuel and you just wasted your money because they never get used any way?

On the weight loss side, yes, but indirectly. If you exercise typically during your fuel transition you’ll have much lower energy and your workouts will suck for a while and the ketones are literally rocket fuel. Because they’ll boost your energy through the roof you can go along as usually which will obviously help you burn more. If you don’t work out it’s really not worth the price IMO.
You’ll find a lot of hate here for Exodenous Ketones, I’ve used them a million times over the last 3.5yrs and if I could afford to always have them when I wanted them, I would. I feel most people who bash them have never tried using them. Being cranked up on ketones isn’t a feeling you get when you’re running on your own supply. Think a half-caf coffee vs quadruple shot cappuccino and the whole “mental clarity” cranked way up. It’s addictive for sure.
