Going on an actual calorie restricted diet while consuming cannabis is basically impossible for me.
Then instead of walking 60 minutes I end up sitting and listening to music.
There is really not anything for me that correlates with healthy behavior when I smoke.
Set and Setting are also relevant too. If you do it a soecfic way with other soecific tools and activities while on it, that all gets packaged and reinforced.
As the other comment says: set and setting. And it works both ways, you can take some memento with you, and when you're being quiet and introspective and you're feeling good fondle some fob: a keychain, a rosary, buddhist prayer beads, some macrame you're working on, it doesn't matter. Point is later when you're in a different situation, you can replay that ritualistic behavior and it will probably reach in and remind your body, which will then remind you mind. This is human nature: it's known that e.g. humans remember / forget things when passing through doorways, and some forms of acting use cues like this especially for emotional resonance.
