A New Diet Fad Has Just Arrived! the Idea Is

question 45

Short Answer

A new diet fad has just arrived! The idea is to drink cold water; the body has to burn up glucose to furnish the energy to warm the water to body temperature. OK, so let's see if this idea is reasonable. How many liters of water at 5°C would one have to drink to metabolize 1 kg (2.2 lbs) of glucose and lose that much weight? Body temperature is 37°C. Glucose is C₆H₁₂O₆ (180 g/mol), and the enthalpy change for the metabolism of glucose is -2,802 kJ/mol.
