The conversion efficiency of energy from respiration into mechanical (physical) power depends on the type of food and on the type of physical energy usage (., which muscles are used, whether the muscle is used aerobically or anaerobically ). In general, the efficiency of muscles is rather low: only 18 to 26% of the energy available from respiration is converted into mechanical energy. [22] This low efficiency is the result of about 40% efficiency of generating ATP from the respiration of food, losses in converting energy from ATP into mechanical work inside the muscle, and mechanical losses inside the body. The latter two losses are dependent on the type of exercise and the type of muscle fibers being used (fast-twitch or slow-twitch). For an overall efficiency of 20%, one watt of mechanical power is equivalent to  kcal (18 kJ) per hour. For example, a manufacturer of rowing equipment shows calories released from 'burning' food as four times the actual mechanical work, plus 300 kcal (1,300 kJ) per hour, [23] which amounts to about 20% efficiency at 250 watts of mechanical output. It can take up to 20 hours of little physical output (., walking) to "burn off" 4,000 kcal (17,000 kJ) [24] more than a body would otherwise consume. For reference, each kilogram of body fat is roughly equivalent to 32,300 kilojoules or 7,700 kilocalories of food energy (., 3,500 kilocalories per pound). [25]

Nobody asks Tom Colicchio how he fits into his tuxedo for the Emmys; nobody asks men who they're wearing on that red carpet. On the other hand, I spent years as a model and writing for fashion magazines, and I'm genuinely interested in fashion — I too enjoy the spectator sport of seeing what everyone wears on the red carpet. In my household, where I'm constantly getting my hair and makeup done for press regarding Top Chef and other projects, my daughter bears witness to an unnatural focus on my appearance, by me and other professionals.
