I think it’s fine. It might make you grumpy, but in terms of weight loss, there’s no problems.
My window moves a lot some weeks as I frequently have work meetings around lunch time, so sometimes my first meal is +- an hour or two.
It works for me. Except I don’t do OMAD, but TMAD always. It’s difficult for me to include all the calories in one meal. I eat two full meals, meaning lunch and dinner. Snack would be too small for me. With eating window, I dance around.
Well I haven’t tried it yet really, so no idea what shape it will take. But I know I need to mix something up!
Yesterday I had to eat lunch either at 12 or nothing until about 6, so I ate at 12. Today I ate lunch about 2.30, and I’m only out between 3.30 and 6.30, when I’ll eat dinner. So I thought there was no need to eat a large lunch, so just had a small salad, and I’ll eat at normal sized dinner.
I’ll report back on results! :-)
