Keto Vibe Ketosis produces molecules called ketones in the blood. One of these ketones is BHB or beta-hydroxybutyrate. BHB works to block the enzyme called citrate lyase. This enzyme converts carbohydrates into fats, which might lead to obesity. The major ingredient in the Keto Vibe is this -BHB. It naturally burns stubborn fat. This increase in energy increases metabolism. Serotonin, a body chemical that regulates digestion is also released. This reduces the appetite resulting in less food intake.
