The Atkins car is 16G protein/3G carbs/2G sugar so I think it's okay to replace a meal. Sometimes I get chipotle for lunch as well, though I find if I can do the bar 3-4 times a week it helps with weight loss.
I have a ways to go, I have to lose 20 lbs to get to where I was in that picture (215).
Tonight for dinner, making porkchops will get some salt/pepper/lemon, broiled, and some carrots which I will probably dice up and sautee with a honey / soy glaze.
Just to put it in perspective, before the holidays I ate whatever, drank whatever, and I balloon up pretty bad.
bars like that are not [actual] meal replacements (nutritionally poor), just supplements. you might actually be better off with a non-atkins one, given you are not keto, and lifting weights, so if something offered more protein for the same or less calories it would probably work out better. some mexican protein bars i just bought today are 249 cal for 65g bars with 23g of protein. fat 4g, carbs 28g, but i would also argue 'who cares' for both. it also takes your body more effort to digest protein than it does fat or carbs, so (assuming same calories) more protein = more muscle building potential + more energy consumed by digestion.
your overall intake seems low if your average day is coffee/bar/omad so i'd expect you to be on a food strugglebus but also drop weight pretty quickly.
