Lean X Diet UK works primarily by encouraging your body to enter ketosis, a metabolic state where your body burns fat instead of carbohydrates for energy. Normally, our bodies rely on carbs for fuel, but in ketosis, fat becomes the main energy source. Lean X Diet contains exogenous ketones (usually in the form of BHB – Beta-Hydroxybutyrate) that can help kick-start this process. https://www.facebook.com/lean.x.diet.uk/
