It is hard getting back on track again. When I get off of my schedule, what I usually do is work my way back on again with longer periods of intermittent fasting.
This was how I started in the first place, because I wanted to have a long enough overnight fast for my body to go into healing and autophagy, so I started having an early dinner/late lunch and then fasting until morning. Once I was on that schedule, I wanted to not have much for breakfast because we go to the fitness center, and I can’t swim as well if I have eaten breakfast; so I then started having just a protein drink or part of a protein bar with my morning coffee.
When I eliminated that, then I was into OMAD.
I still go back and forth, depending on my schedule, and whether my body seems to need to eat something at a different time, and then back to OMAD again. Some mornings, I have a little protein before swimming, and sometimes not, but just the one regular meal each day.
