A man takes a diet equivalent to 10000kJ per day and does work, spending his energy in all forms equivalent to 12500 kJ per day.What is change in internal energy per day? If the energy lost was stored as sucrose(1632 kJ per 100g), how many days should it takes to lose 2 kg of his weight? (Ignore water loss).
