I'm a 70 year old formerly fat T2 controlling BG with diet rather than diabetes meds so my needs are somewhat different than most of his clients but science is science. I always regard it as a good day when I learn something and I learned several things yesterday.
Lyle is definitely top of the game. If you want another, more layman but definitely highly respectable perspective, John Berardi's Precision Nutrition website is a great source.1 -

I'm just glad that I'm not going to get cancer of the AIDS right now...

@midwesterner85 - regarding making glucose from fat, perhaps you should read this:

I have read/heard multiple times fat can be converted to glucose. It is just highly inefficient and not direct. I really don't think you need to eat as much protein as you think you do to make sure you get the glucose your brain needs without losing muscle.3 -

Yes, I thought there was something there. Here's what I know: I was in DKA once... I know this isn't "normal" and isn't applicable to 98% of the rest of the population, but it was a noticeable difference in a short period of time. So in 2 days, I lost about 50 lbs. I almost died, BG was 938 mg/dl, and this is not a good way to lose weight. However, after getting out of the hospital with fluids fully replaced, I was still about 20 lbs. lighter. As I was losing, I recall being able to notice that belly fat was clearly decreasing (more so on the right side than the left... not sure why). As my BG rose, I couldn't get to that glucose without insulin and my body thought I was starving. So it kept creating glucose. That glucose was mostly coming from fat. I know it's anecdotal, but I do find it hard to believe that fat is unable to be converted to glucose at all. I can believe that it is inefficient, though.1 -

Fat is broken down into fatty acids, one of which is glycerol and it becomes glucose.3 -
