I was lacto-ovo for about 23 years, and when I went LCHF/keto, I added seafood back. I still do not eat red meat, pork, or chicken. However, I do quite well protein-wise with fish, shrimp, eggs, dairy, etc. I still eat some tofu, but I’ve also dialed the fake meats waaaaaay back existing as my version of occasional “keto junk food.” (It’s my guilty pleasure to have two LightLife tofu dogs in a low carb wrap every few months or a Morningstar bac’n, egg, and cheese wrap–heh, heh.) These days, I eat eggs and some type of seafood on a daily basis. I honestly believe that I can attribute my lack of cravings for the most part to sticking to real, unprocessed, whole foods by and large. I do think that a <20 g keto is more difficult without a non-plant protein source, and I do think a 35-50g LCHF plan will offer more flexibility. However, if you can mind those B and D vitamins, I say go for a lacto-ovo veg version of keto!
