Honestly Robin, I have absolutely no idea.
I’ve never counted calories myself, ever. I only stay under 20g carbs daily and this has always worked for me. I can tell ya that the meal itself was 20.6 carbs, since I added the Rebel at the last minute. … Wife asked since I was Fasting again this week, if I wanted one since I haven’t been eating any lately. So decided to get one today.
Egg’s = 3.6 carbs @ 0.60 carbs each @ 6
Sausage = 0 carbs, but only ate half of the 16 oz roll
Onion = 10 carbs, @ 2 carbs per ounce, and it was just under 5 ounces.
Rebel = 7 net Carbs per pint.
It’s always been mentioned that my meals may be a wee bit big?
… Ok, they are generally quite large.
But to be honest, a lot of days I do OMAD, or two total. But do also like to eat those things that are low/to no carbs to begin with. But when I do go above 20g a day, it’s no more than 25c. I will generally throw in Onions and the like here and there, since I do like them. But I also forego them at times where I won’t eat any for months. I just like to throw them back in once in a while.
But can also honestly say that I never feel bloated after a nice big ole’ meal like these… Back in the day, before I switched to this @WOE, I could eat sometimes even half the size of these meals and feel quite crapy shortly after. Such as one might feel after eating a big ole’ Thanksgiving meal with the works. Ya know, where they sit back on the couch, loosen there belt to breath easier, and then act like they are watching something, or listening to folks talk, when they are really just falling asleep. 
As I mentioned, I’ve been Fasting 60+ hrs. for the past couple weeks, so this too is a nice change. But I feel that overall activity levels has the most effect on things. (At least it appears to be) From the times I get stuck in my office behind the computer all day, or getting out and about in the field. (Which includes my Hunting too. It’s a 0.65 mile hike from my house each way, with all my gear.) I do believe that these sorts of things are/can be game changers as to how I feel, or seeing results.
