Wow.

Yes, insulin resistance does protect against weight-gain. Severe insulin resistance (T2D), is even known to cause dramatic weight loss.

If all we're going for is weight stability or lowering, then insulin resistance is the way to go.

If, however, we'd also like to live for a bit while thing (and keep our toes and kidneys), it might be a good idea to ignore that insulin resistance can induce weight loss. Some things that cause weight loss aren't really good for us, like...oh, say...cancer?
