It's different per thing. Yes, working out gives me energy (even though I hate it and am bored out of my mind doing it), but going hungry or resisting food isn't the same kind of thing. If I had a bad day at work, I'll usually go "fuck it" and eat a pizza. If I've gone hungry all day because I'm eating what I should, I'll be cranky and not as much fun.
I can definitely relate with the GP, even though your comment is relatable too. They're just different mechanisms, or they apply differently to different people.
Tangential to the discussion, but I'd encourage you to not give up trying to find a form of exercise that you don't find boring. It makes it much easier to get adequate exercise. Also, not having to spend time doing things you hate is nice.
For example, personally I find lifting in the gym or running on the treadmill to be quite boring. I like biking and running outside, especially on trails. A lot of people enjoy group classes like crossfit or yoga, since the social reinforcement can make it psychologically a lot easier.
Καλή τύχη.
