Hi Ishimura, I had some similar issues. I was slim when I embarked on keto, lost 4-5 kg, I could say that was water weight except my family noticed and told me I looked thinner. After some time on keto, which was working well, my body began to desire carnivore foods. I still mostly eat like this, meat, fowl and fish, but I had to reinstate a few vegetables, for fiber. Despite already taking magnesium citrate.
At first it was great, just indulging in my favourite foods, and definitely felt my brain fog dissipating. Then my energy gradually decreased, and I ended up with stomach pains from constipation. I added back in broccoli, and this helped. I will also add back in cauliflower and green beans.
For me, eating a mainly meat/fowl/fish based diet, with the inclusion of a few vegetables (in small quantities) is the best I can achieve. Amber O Hearn shared a passage in her book, of William Banting’s lowcarb diet (described in his own words) in 1864. He was eating a mainly meat (meat/fowl/fish) based diet, with a few vegetables in small quantities, a rusk or a dry piece of toast. I believe something very close to carnivorous yet not entirely exclusive of plants, would be the best for me. But then … I don’t have the time to be going through a lengthy adaptation period adjusting to the WOE when I require my energy as a stay at home mom. And I was beginning to drag my feet after me, as well as being constipated, so something had to change. I think we can all only do our best, but that also, it’s very important to listen to what your body tells you. Science should never get entirely in the way of intuition, as there’s much confirmation bias, and we’re not gods, nor do we have sufficient knowledge.
