I know what you mean.
Sometimes I truly miss shoving junk food in my mouth. I miss the taste, the mouth feel, the inhibitions, the feeling of over fullness. But I don't miss being obese and lethargic. The way we're made, we cannot have both. It's a choice.
You are fit enough that you can get by with a donut or two. I exercise enough that I can have some food indescretions and not gain. But that eating way way way too many for a single person, well, I've had to say good-bye to that behavior. I miss it sometimes, but I don't miss the way my body was then. I much prefer my new body! It's okay to miss it sometimes though.
