A weightlifter manages to lift a 133 kg (that's 293 pounds, which sounds much more impressive) weight a distance of 1.4 m. How many kcal of heat energy is equivalent to this lift?
133 * 9.81 * 1.4 = 1826 Joules
convert that to calories and then divide by 1000 to get kilo calories (food calories)
436 calories / 1000 = .436 Kcal
This would not be an efficient way to lose weight :
