Yes of course. The impact of caloric restriction on metabolism however is FAR overstated as we know from the available literature. "Starvation mode" is largely relegated to pseudo science at this point and most of the reduction in metabolism you speak of is due weight loss itself and a small reduction in NEAT. But yes the human body is a complicated system effected by hormones, and other individual factors. However it is important for the layman to understand the basics. It VERY rarely helps people struggling with weight loss to gloss over the basics and talk about metabolic adaption or provide other "excuses" like PCOS, hormones or starvation mode. They miss the forest for the trees.
