Waste of money, pure hype. These products cannot and do not put your body into nutritional ketosis. The only research these products fall back on is that the urine shows ketones because you're drinking and peeing them. That is not nutritional ketosis. To be in nutritional ketosis and burn fat, your body needs to be producing acetoacetate and beta-hydroxybutyrate. Ketone drinks only have beta-hydroxybutyrate. Acetoacetate is the primary keytone needed for ketosis and cannot be artificially reproduced as a supplement. Therefore, these supplements simply mimic one part of ketosis and are a waste of money.
