I've hit a glucose level of 55 many times, so I know full well what it does to your brain, and it's not safe to be on the road.
Nope. That fat might be good for safe calorie restriction diets, but skipping food and exercising is going to lead to a blood sugar drop, and that is stupid dangerous.
I strongly disagree.
When I was doing it, it was working for me and I was not disoriented or fatigued ...occasionally I would "bonk," run completely out of available energy, but I kept things controlled enough that I was never more than a couple miles from home and never had a problem ... and always had that Powerbar if I Really needed it (which on occasion I did.)
Lately I have tried just working, not even exercising, on little or no food, and I find I don't have the energy to even sit in a chair.
I don't know what has changed, but I wouldn't dream of trying to exercise on am empty stomach now. Then too I have lost a lot of fitness due to injury and illness.
This is part of why I keep saying "No one knows." Every one of us is different, and every one of us is changing. What is great for one might be dangerous for another.
I know I have been exercising and studying (at least a little) nutrition for for about 40 years. I know a lot of different things have worked for me. I ma trying to learn what works best now ... but it isn't what used to work, or what worked best before that, etc.
But I have been at this long enough to know at least, when something is or isn't working.
