Alpilean is created for people disappointed by fad diets, workout plans, and diet pills because they failed to show any results. One thing that most plans and products ignore is the core body temperature, which basically means the temperature of the inner organs. This temperature is different from the temperature of the skin and deeply impacts cellular functions. If the core body temperature is low, the body experiences slow metabolism, weakness, fatigue, stress, low energy levels, and a feeling of tiredness. It is possible to experience low core temperature even when the skin feels alright and normal.
