I found this video (below) very interesting; the TL;DR is that he’s a neurosurgeon who also seems to have a business set up around getting people fit using a modified “ketogenic” diet of about 50-55% fat, moderate protein, and low-moderate low-GI carbohydrates. I was particularly interested because that’s probably how my macros shook out when I had the most success at the beginning of doing LCHF protocol.
Another very interesting note is that, though he doesn’t use this language, he distinguishes between fat adaption and ketosis. You can, it seems, be fat-adapted while at a low level of ketosis as measured by blood or urine ketones. You can, it seems, be burning fat even if you aren’t in ketosis – at least that’s my layman’s understanding of what’s being said here.
Having tried quite a few variations of LCHF and keto, this is probably the one I will try next: I’m going to increase my monounsaturates, reduce saturates, reduce fat in general (less cream, less olive oil on the oven-roasted veg), and I’m going to (gasp) increase my intake of low GI veg while pushing my resistance training workouts. I may add back Metformin too, though I suspect one of the main reasons my body has reached this homeostasis is that, despite the keto hype, it’s hard for your body to put on muscle mass on such a low level of carb.
I will continue with these “heresies” until I find what works for my body. Stay tuned!
