We're similar, but I'm not strict keto. I do IF and will often forget to eat. For example, Saturday I wake up, weight workout, train jits for 2 hours, then it's ~12-1pm. If I don't think about eating right then and I get closer to 3pm, I'll just wait until dinner.
Before people say I'm weird and never get hungry, not true. Before IF, I used to wake up in the morning because I was hungry. Early in IF it was hard. But, the body adapts. You push through, and now I feel at my best mentally and athletically before my first feeding of the day.
Also like you, while I don't follow a strict keto diet, I cook most of my meals and stay pretty healthy including rice or potato only sometimes. If I go crazy and have a carb heavy meal, I do end up hungry the next day. Understanding one's body is the advantage of getting old I guess :D
