Don’t beat yourself up over it. Life happens, just get back on that horse. I was doing the same thing in February of this year (wife’s birthday, valentines day, gatherings with the in-laws, etc.), and although I wasn’t comfortable veering away from keto foods, I let other people persuade me that it would be fine, it won’t hurt, etc. When I saw the weight creep back up after those slip-ups, I told myself the backtracking wasn’t worth it (and I was still fairly new to keto at this point). So, now I don’t have carb-filled cheat meals, just delicious keto friendly “cheats” that would take too much work to cook myself at home. And now when in-laws try to convince me that whatever food they’re trying to stuff down my throat won’t hurt me, I can kindly decline (over and over since they’re persistent), and back up my reasonings why with some of the great science I’ve learned from the podcast.
Anyway, just stay focused and you’ll be on track in no time.
