The lower carb is a definite benefit, and I've stayed with that. The two books I read talked about an adaptation period and I toughed it out for six weeks. It cost me a year of recovery. Being a little bit less active is probably a good thing. There was some support for that in the books, but I don't know how what methodology was behind that conclusion.
This diet could be considered a modification from the Atkins, substituting fat calories for protein. I suspect one of the posters above was an successful follower of Atkins. There are health issues with too much protein as well. There are ways of getting those electrolytes/minerals and I'd study up on that sooner rather than later. It may well have been my problem that I'd done enough damage so that I wasn't recovering while still in Keto. Personally, I'm very sure the diuretic was a big part of the problem. I was able to stop diuretic use without swelling up.
I will try again and go with more of an intermittent approach. amping carbs when I'm exercising. Long slow hikes will get you into keto as well, but my fitness has not been up enough to do more than 3 or 4 hours max. FWIW, the two other people I know who tried it were not able to keep it up either, not sure how long/hard they tried. One of them was Linda Sands of the Sandcastle who should be familiar to some people here.
For me, my thinking is nothing but complex carbs. My idea is that you want all the veggies you can eat with a taste satisfying amount of healthy fat. An ideal meal is a big salad with some meat or a stir fry. I also make a wicked turmeric bacon chicken soup, the bone broth is supposed to help with adaptation as well.
I hope it works well for you, let us know how it goes. And definitely keep those carbs down, even if the super low doesn't work for you.
