fat is a very energy-dense substance: it packs about 4,500 food calories per pound, the same as gasoline, and 15 times as much as in TNT.

Ummm...a pound of fat equals 3,500 calories. The esteemed physicist is off by 1,000 calories.

When you lose weight, most of your fat is converted to the gases carbon dioxide and water vapor, and so you get rid of fat by breathing it out of your body.

Where he gets this little tidbit, I'm not sure. AFAIK, fat is burned by your cells for energy; it doesn't just "evaporate" off your body. One of the byproducts of cell respiration is carbon dioxide, but water vapor??? You lose water vapor through breathing whether you are dieting or not. 
It seems our dear physicist is still taking a very Puritan attitude towards weight loss. One that says, you can't achieve weight loss without some form of suffereing and deprivation and that those things are good...almost a form of penitance for having been such gluttonous pigs to get overweight in the first place. |
