Hello
I'll tag
@TorqPenderloin for you who I believe is a regular gym goer and resistance trainer.
LCHF is not just for T2's as non-diabetics can also follow this dietary approach. Equally, a T1 could go down a LCHF way of life - although there are advantages and disadvantages to that as well.
All I'd say about high protein and low carb, is that you may find that you need to bolus for protein (and a fair bit for some of us) in the absence/limitation of carbohydrates. It's a phenomenon called gluconeogenesis I think, and although it's pretty cool in theory - it's also very annoying.
I'll also tag
@robert72 who is a notable member of the forum who follows a ketosis diet. I'm not sure about his protein intake, but if you have any questions regarding LC - he'd be a great source of info/advice
If you're looking to try a drastic diet change, the best way to do it is shoot straight down the middle and then lean either way till you find what works for you.
