Like @Tripler, I didn’t have a real hard time with the keto diet. Yeah, giving up beer was the hardest part, but I got used to having a couple rum and seltzer water drinks on the weekends instead.
My keto superpower was being able to go long periods without feeling hungry. I remember one all-day marathon meeting I was in at work where they were very late bringing lunch in and everybody else was starving, mowing through the little bags of chips they had out. I was just fine and dandy, feeling very smug watching everybody else shoving all that crap into their mouths.
And being able to eat high-fat food guilt free was nice. Bacon, butter, eggs, cheese! (I did try to eat healthy fats too, on occasion). I mean, I still eat that stuff now, but with carbs, so no longer guilt free,
Finding substitutes for a ‘base’ for meals was tricky. I do most of the cooking in the family, and I could make a pasta sauce that was keto, put it on actual pasta for the rest of the family, but what do I put it on for me? Zucchini noodles didn’t do it for me. I found this ‘Palmeri’ brand of pseudo noodles made out of hearts of palm that were pretty good, but pricey. And I like to make a lot of stuff you normally put over rice, like stir-fries and gumbos, and I got real sick of cauliflower rice. I did find a good bread substitute recipe using almond flour so I made my own bread for sandwiches and hamburger buns.
