Oh, yeah. Dysphoria is fundamentally the discomfort we have with our own body, the mismatch between what we got and what our brain wants. In trying to resolve this constant stress, I believe we can sabotage ourselves in a huge number of ways. Personally, I grabbed snacks and cut corners on my exercise, while gumming up my psychic plumbing with depression and anxiety.
I dealt with part of this, the "It's only 100 calories, fine for a snack or eight", and "45 minutes? Close enough to an hour of exercise." bits by harnessing my obsessive-compulsive project managing behavior, turning myself into a project and logging EVERYTHING I ate, weighing and measuring absolutely everything and entering it in tracking software (MyFitnessBuddy app). That was an eye-opener. I've altered my diet to hit my target numbers I worked out with a doctor, and after a few years I'm doing much better.
I'm also in therapy, working on the dysphoria, and have the depression and anxiety well controlled now.
