Firstly, I'm not going to pay attention to anything Lyle ever says or does. Dude is a fucking idiot, I'm only going to take advice on diet and excercise from people who are bigger, stronger and leaner than me. Lyle is none of those things.
If by "knowledge" you mean studies or whatever, there are plenty on PubMed, but that's besides the point (you can find studies to prove just about anything).
There is also evidence that limiting carbs to the morning is a good weight loss strategy for the general population (but that is only for weight loss, not necessarily fat loss) and that the opposite is true for recreational athletes and people that train (limit carbs to the last meals of the day).
And there is a ton of studies that cover that fat burning properties found in many healthy fats (CLA's etc).
As has been said, calorie deficit/surplus is the most important factor for weight loss/gain, macro's are largely a personal bias (how each macro effects you and what makes you feel the best personally in terms of energy and mood and whatnot).
My main point is - fat is not bad. Fat is very good.
My second point is - there is more than one way to do things.
When I want to lose fat I prefer to increase activity rather than lower cals anyway.
Rich Piana is prob bigger, stronger and leaner then you.
