“You know you can poop and pee out calories right? Just because you eat something doesn’t mean it gets absorbed and used by the body…” - Snowflake
Congrats. You just discovered both sides of the energy equation are subject to change.
“So in the in-out=accumulation energy balance, ‘out’ is equal to expenditure + excrement + whatever else. What macronutrients get used for is ENTIRELY dependent on how your hormones allocate them.”
That does not change the fact of energy balance, it just changes the variables in equation. Something dipsticks like Taubes can’t get through their frigging heads.
“But If you want to get really technical, the enthalpy of sweat droplets ought also to be counted.”
No, if you want to get really technical you would say: Energy In (corrected for digestion) = (BMR/RMR + TEF + TEA + SPA/NEAT) + Change in Body Stores. BMR/RMR is your base rate, required by body processes. TEF is the thermal effect of food which varies among macro nutrients and this affects the energy in portion of the equations, TEA is exercise and fairly self explanatory, SPA/NEAT is non-exercise related activity like walking around at work, getting up and down from your chair, etc. Change in body stores is also self explanatory. And all these variables are subject to change which changes the sum of the equation in terms of energy in vs energy burned and body stores. If you eat less and lose weight, your BMR is lower, TEF is lower, and SPA/NEAT will likely be lower via unconsicous compensation. Hence a 400 calorie defict in diet will only result in only so much weight loss before a new equillibrium is hit and calories will have to be lowered again. And that equillibrium weight will always be higher or lower than expected for people like Taubes who can’t seem to wrap their heads around a dynamic equation like that due to: higher/lower BMR, higher/lower TEF proportionate to calorie intake and macro ratios, higher/lower SPA/NEAT, and water retention/loss.
“You know that Lyle Mcdonald advocates a ketogenic diet for pure weight loss right? From The Ultimate Diet 2.0:”
Yes, because manipulating macro nutrients will allow you to some degree affect what tissues are lost vs maintained. It will not however let you violate the laws of physics. I’ve read all of MacDonald’s books and in all of them he is quite clear that all diet strategies can do is favorably alter some of the terms of the energy equation to help preferentially maintain muscle and lose fat during a diet, they do not invalidate the energy equation itself, nor is there something magical about carbs or insulin.
“Taubes isn’t like a super diet expert though. He’s just enough to get people started on nutritional education. But his emphasis is basically correct for a fat loss diet. He and McDonald agree.”
I suppose that’s why McDonald has called him a moron and an asshole and other choice words on his website’s forums; it’s because they agree and he has the highest respect for Taubes. He has also used the phrase “A steaming pile of horseshit” to refer to Taubes’ work before. Sounds to me like they’re in total agreement. Here’s a further quote directly from McDonald on “Metabolic Advantage”:
"here’s an example that is relevant to this thread: some low-carb studies suggest a metabolic advantage, othes don’t. Which are right which are wrong?
"In this case, none of them. Because whne you sit down and divide up the ones that show an advantage vs. those that don’t and look at the differences, here’s what you find:
"Those that do ALL use self-reporting of dietary intake and/or had drastically differing protein intake (confound: dietary protein makes people eat less)
those that don’t ALL use strictly controlled dietary intake."
Or in other words, what Taubes and the like do is cherry pick studies with nice abstracts but poor controls that seem to support the message they want to deliver. They do this because of the cottage industry of online researchers that have access to PubMed abstracts but not full studies. The bottom line is when you have a study done where the test subjects are sequestered and their diet and activites subject to strict controls, all the hormonal crap goes out the window and the bottom line is seen: calories in vs calories burned.
“There was a thread on Taubes earlier, and many mises.org members posted they had lost 25+lbs since reading him.”
On a site like this where everyone has a logical fallacy probe big as a dump truck up their ass, you’d think you’d spot the problem here. Eating fewer to no carbs is usually a good diet strategy because:
Protein has a higher thermic effect.
Carbs make up a massive portion of the typical US citizen’s diet, so avoiding them means by default a massive calorie deficit which would be hard to compensate.
Protein makes you feel fuller, carbs make you feel hungry, hence you tend to eat more on a moderate to high carb diet when you realize it or not, and less on a high protein/fat low carb diet whether you realize it or not.
Absolutely none of the above invalidates the energy balance equation.
“I just pointed people to Taubes because its correct in its fundamentals, breaks through the AHA nonsense, and really works for a lot of people.”
Taubes is entirely wrong in his fundamentals. Low carb diets are an effective approach to dieting for many, but not for the reasons he is claiming. You can lose weight just as well eating fewer calories than burned one way as any other way. But some approaches give an advantage for various reasons, not the least of which is psychological, and none of which are a violation of the laws of physics.
