And of course there are the exceptions to these rules - the women who just want the facts and the science behind the workings of LC.

A few points:

Yes, too much protein can make you fat when eaten with carbs. The amount you would have to eat in the absence of carbs would make your head spin. Excess protein is converted into glucose by your body - but it is released so slowly that it does not produce a rise in insulin.

Not all foods stimulate the release of insulin. Fat is metabolically neutral. I causes no change in insulin or in glucagon . In the absence of insulin fat cannot be stored. Period. In the presence of insulin fat cannot be burned either.

I hope your brother is OK.
