Ketsosis is not a starvation response. Your body burns one of two things for fuel. carbs----> glucose or fats -------> ketones.
False. For example, many cells can run directly on fatty acids while in ketosis. Some tissues can use ketones, some FFA, some glucose, many some combination of the three.
Using fats ----------> to ketones is much better fuel source vs. glucose.
Why?
What it is, is in the West where carbs dominate and people have been brainwashed into believing that carbs are the preferred fuel source when in fact, they are not. Your body to include your brain runs much more efficient as fats as a fuel source. Remember 1 gm of carbs = 4 calories (energy) 1 gm of fat = 9 gms. You get more energy out of one gm of fat vs. 1 gm of carbs.
What does this have to do with "efficiency"? Also, anyone can easily meet their energy needs by eating the same amount of calories from carbohydrate as fat, so how is this point significant whatsoever?
The problem is, your average person doesn't have the willpower to get into ketosis and stay and let it do it's thing so they do it for a week and quit and say how horrible it is. It takes time for your body to change from using glucose as a fuel source to fats.
Possibly, but what about people who have tried Ketosis for more prolonged periods and still reported ill-feelings? Thongwarrior, for example, tried a ketogenic diet for at least a month, if I'm not mistaken?
That said, I've heard varying stories about the "keto adaptation" period, with some saying it takes more time (e.g. 3-6) months. I've even heard "years", but mostly from random youtube gurus, so I don't take those claims too seriously.
There is no dietary need for carbohydrates. Fats do what carbs do better (monosaturated fats preferably then saturated fats).
There's no dietary need for much of anything. You can live for quite a long time, just scraping by in a state of starved lunacy... I would know. While carbohydrates may not be "necessary", a diet which includes them certainly has a
different effect on the body, and who's to say it's worse?
Well, Wiggs, for one. Again you claim fats are a "better" energy source than carbohydrate. Why? What about the lower power output, changes in brain chemistry, etc.? Are these all for the better?
For bodybuilding offseason, different story. For carbing up for a show, different story. As far as dieting, no carbs are needed (sans a refeed). Ideally (grass fed) animal proteins with fats and organic veggies and monosaturated fats is the ideal get ripped and get healthy diet. Keto is very good for your brain, mood, performance etc.
What kind of "performance"? Are you just talking about dieting, or staying in ketosis long term? And most importantly, are you speaking from experience?
