Sorry to branch out:
How does this one meal per day work for you? There is recommended calories for a person, do you have to follow it somehow to make sure you have enough energy and exercise?
Now I either do gym before dinner (heavy exercise) or social dance after.
I’ve been given a lot of advice how I “should” be structuring it - like “don’t eat too much before bed” or “never eat before exercise” … but I haven’t had any issues with what I’m doing so far (~2 years)
