Not sure how if you've found the same for yourself, but for me, my body adapts quickly to certain items that I consume - such that any deviation from the schedule and I get minor/mild discomfort.

e.g. Switching up meal timings after eating consistently for a while, or stopping my morning coffee, or a sudden reduction in water intake, etc.

I think what works best (for me) is to have a varied approach where you don't stick to one schedule/program.

I don't know that I feel a bodily difference, just annoyance. My approach is discipline and putting in effort to make sure I keep up with routines that I've noticed have a positive impact on me
