Bottom line is if YOU are happy with your rate of weight loss (and ur labs some back satisfactorily) then u don’t need to change anything, really.
You know yourself best and can tell more than us strangers if this is a slippery slope or not. Some can handle it and keep it in check, others may have more difficulty, and should consider refraining.
P.S. I ate almost 2 cups of mushroom “chips” for dinner the other day, so yeah, it happens, lol. BUT: I’m 2+ years out and in maintenance for over 1.5 years.
Good Luck!
Edited to add: oh, and to answer your original question: no, I didn’t eat these types of food during weight loss phase.
