I find it confusing as well.
I think people use the term BSD very loosely and they mean different things by it.
I’ve been reading posts on this site since approx. Sept 1 … and i tried the 800 for a few weeks but didn’t succeed most days, got sick, gained weight back … so i’m going with the plan that seems to work for most. I am doing this to reverse diabetes and get healthy … it’s a must for me.
I am doing 800 calories and 50 carbs or less. I’m sure i will fail sometimes.
I’m trying to make sure i get some fibre every day … helps with constipation.
I am also going to try and reduce my coffee/cream. I tried to just reduce the cream … but i don’t like it so i am going to try more tea drinking … i don’t like just water usually.
