I like almost zero keto-friendly foods (on their own—most are great if you put them in rice or pasta, or on some flatbread) that aren't one or both of very expensive and time-consuming to prepare, and even those I usually stop liking much after the first few bites.
Going keto would mean hating eating forever. Which would be very effective for weight loss, I guess.
Ultimatley, what kept me on track was the improvements I was seeing in the gym. I did, however, always acknowledge that was fighting the temptation to cheat quite often.
