I avoid fruit now. But 18 months ago, when I started low carb high fat eating, I was not interested in ketosis really. My view, after reading Taubes’s book, was that reducing sugars and starches was good. I used to eat so much crap that cutting all of that out, while leaving the fruit, was more than enough. Those 3 months were the biggest sheer weight loss I experienced.
You don’t have to be holier than the pope to cut your carb intake. Sure, I think there are benefits to ketosis, but simply cutting sugars (especially in processed foods) and starches got great results for me.
So sure, I wasn’t keeping 100% to “The Diet” at the beginning. Do what you feel comfortable doing. I’m quite sure that if your diet sucked to begin with that you’ll see benefits simply by going 80% or 90% of the way. Plenty of studies have shown that low carb diets that aren’t even close to ketogenic are highly beneficial.
To be honest, it sounds like you’re overanalyzing. Eat veggies and meat and fish and healthy fats to satiety. That’s basically the lifestyle. Read the PDF. It’s not hard, and you won’t feel deprived.
Having said that: Dr Peter Attia has frequently made the point that he takes some patients off ketogenic diets. It isn’t right for some people. Their bloods might go the wrong way, or they feel crap on it. And that’s fine: the evidence we so far have doesn’t show that it’s right for everyone. It just shows that it has a beneficial effect on large portions of sample populations. Your Mileage May Vary is the key here, as with anything.
And frankly, don’t take any of what I or anyone here says as medical advice. It’s just our experience. The science is embryonic at this point. It’s all self-experimentation at this point until we have lots more randomized controlled trials. Consult a doctor, is my official advice to you.
