Will Taking Exogenous Ketones Stop Fat Loss?

Would you like to lose some fat? A ketogenic diet is a pretty good tool to help you reach your goal. You can use exogenous ketones which have been a popular way to help get people into ketosis and comply with the transition from eating carbs to eating fats. Once in ketosis, use real food to stay there. Sounds easy, right? Unfortunately, some bro science complicating this topic has been surfacing which must be quashed. People are claiming that exogenous ketones are stopping the fat burning that people are seeking. The same exogenous ketones that help a lot of people experience ketosis and make getting into and staying in ketosis much easier, which makes the fat loss so much easier. SAD! This is how the logic follows from people who don’t really understand physics but like to quote laws of physics to sound fancy like they know how the human body works: Exogenous ketones contain energy. Body fat is stored energy. Therefore, if you consume any energy, you can’t use any stored energy. That’s not really how the body works. At all. By that same rationale, if you were to eat any dietary fat (or any food), then you wouldn’t be able to burn any fat. Unless every single person who has Continue reading >>

    Why is it that liver goes through all the trouble of making ketone bodies from acetyl coa when the ketone bodies are converted back to acetyl coa in the other tissues?

    Ketones are made when glucose stores are low, then, like you said, ketone bodies can be used by some non liver tissues to make acetyl coA and thus go on to make some atp. However, if glucose stores are low then the liver will turn to beta oxidation to make energy. Fatty acids go through beta oxidation and one of the products is acetyl coA. In order to go through beta oxidation, there needs to be coA avaliable. If the liver made acetyl coA and kept shipping it out the supply of coA would deplete, and the whole point to produce energy without glucose would be harmed due to a lack of coA for beta oxidation

    But by converting acetyl coa that was provided by fatty acid to ketone bodies and shipping them out to other tissues, aren't you depleting coa?
    Am I missing something?
