That product isnt instant ketosis, it merely helps ease the body's transition to ketosis. I guess there's usually a carb withdrawal that it helps ease.
in this case the beta hydroxybutyrate is attached to four salts that carry them into the system that gets ketones into your blood instantly that is followed by the mct which forces the body to produce exogenous ketones by burning fat. It is the combination of the two that makes the product work. Look up Dr Dominick DeAgostino he discovered this product to use for Navy Seals who were suffering from brain injuries due to oxygen deprivation. Ketosis got rid of the issue because you need less oxygen to burn fat then glucose. You can take a blood test or urine test and it will confirm that you are in ketosis. Many people tried to copy the technology he discovered this is the only real deal. I know at least 10 people who are using the product and they have all lost inches off their waste in less than a month. It is new to the market and will be huge. I am looking into it as I want to invest the stuff is IMO the next great product. I take it everyday. In two weeks I lost 2 inches off my waste and am fitting into cloths that I haven't worn for 10 years i haven't changed my diet at all although I am not hungry so I am eating less and I have great energy.
there are a bunch of studies being done at the moment on the product they will be podcast soon from what I understand and white papers are being done. In order to be in sustained Ketosis you need the combination that was the reason a patent was awarded to USF on the technology. There is a second product kegenix rx on the horizon for doctors. All I can say is I feel great and have lost fat but no muscle. It works. They say the eating less and not feeling hungry comes from using fat stores for energy those fat stores turn into ketones.
