InMotion Body Keto Flex >>>> InMotion Body Keto Flex Pills work by supposedly sending your body into ketosis and helping it stay there. I know I promised I’d talk more about ketosis later on in this review, and now is the time! Ketosis is a metabolic state where our body begins to burn fat for energy instead of carbohydrates. This can be achieved by eating a strictly ketogenic diet (high fat/protein, low carb).
