Old-style 8 hour eating window but slightly shortened. 16 hour non-eating. Simple. FWIW I used to do the 12 hour thing. Breakfast at 7. Dinner at 7. Lunch in between. Ditched that and went down to 6-8 hour instead. I've found I can actually do 4 hour eating window but that's irritating for reasons other than hunger/satiety.
