I love IF (totally with you on saving lunch money dreyth haha). It's just super convenient, although I have altered how I do it now.
At one point I'd fast till I train - typically till like 4-5pm then begin binging after this. If I was home maybe I'd start eating at 2-3pm. I generally ramp up carbs on training days, don't count anything though.
I now decided I do better with a little food in me before training, especially now I started cardio...so sometimes from as early as 12am I'll have granola and yoghurt or if I leave it real close to training a protein/dextrose shake and a banana or something.
I have considered training early now I can and the gym is much quieter, so I may switch to what you (coges) are doing.
I eat 2-3 meals maybe, lots of snacking though...very IIFYM really. Withoit counting macros. But I'm still lean so meh.
One of the best things for me is the mental benefits - I can fast all day not have to think about food and get work done with great mental focus. meanwhile everyone else has breakfast, gets a bit foggy as it settles....then they have 2-3 hours and theyre thinking about lunch...then they're away for an hour, have a early afternoon slump, before starting to complain about how hungry they are at 4pm. Then they go home having eaten over half their daily macros whilst I'm not hungry, got more work done, and now have an evening of eating pretty much whatever I want
