Any energy that goes into your mouth goes one of 3 places:
1) You burn it. Literally - and burning food generates heat. Each gram of fat contains 9 Calories, which is equivalent to jogging for one minute. That's 9000 calories (little c) which will heat your average 200lb sysadmin 0.2 degrees F. There are 27 grams in an ounce - that's a half hour run per ounce of fat. Think about how sweaty that would make you. This is an important thermodynamic consider
Might want to crack a book, there. Turns out that the benefit of an Atkins type diet is NOT a result of restricted calories, according to newish studies. Even when Atkins dieters eat higher calories than non-Atkins dieters, they still lose weight.
but that doesn't contradict about 50 years of very well documented data showing a direct correlations between saturated fat and heart disease,
That data was regarding people on standard diets, not Atkins diets. I don't think it's sound to extrapolate like yo
Might want to drop the fanaticism there. Check the studies again. The best there are say you lose weight just like on any restricted calorie diet. Like all things in this arena, some studies show conflicting data, but that doesn't make it right yet.
WRT heart disease, there's nothing magic about the Atkins diet. There are peoples on earth (generally rotund Eskimos for example) who eat diets like it, and people who eat the opposite (generally skinny consumers of Asiatic diets). Across all, more saturated fat makes more heart attacks. Look, if you and the other fanatics keep this up for 50 years or so, and if you all end up dying less, I'll believe it. Until then there's no good reason to, all exiting data points against it.
Re: the mystical powers of ketosis: guess what - the energy is in the fat, not how you consume it. If you wee'd out a highly energetic fatty urine, you'd sure know it. Either the energy is burned, excreted, or stored. Energetic molecules do not make it through your kidney, unless you've got serious problems.
What you mean to say is that the body is only able to extract about 75% of the energy available in the fat, the rest goes to thermodynamic inefficiency due to an alternate metabolic pathway. That's a fine argument and there may even be cases where there's some truth to it... maybe... but basic thermodynamics still applies - inefficiency means heat. You still burn the calories, you just don't get to store them. You do not pee them out.
Furthermore, what you're saying is that one gram of fat becomes heats 2kg of body weight 1 degree plus 7/9 of a gram of fat. Gram for gram, if you're correct, carbohydrate would still be less fattening (and protein slightly less still).
Look, go for it dude. If you believe, more power to you, but stop claiming that you've discovered the holy grail. You're on a diet, neither more nor less well founded or scientific than grapefruit or whatever. Not yet anyway. Collect some data and good luck. For me, I'll stick to eating a well balanced meal and getting regular exercise. It's working fine so far.
