Hi. I'm 41, insulin resistant, and hypothyroid, too. I am doing well on approximately 50-80 carbs (guesstimate, I do not weigh, measure, or track anything, but, based on a former life as a compulsive dieter, I have a fairly good idea of what's what forever imprinted into my memory bank).... but only after I ditched the dairy. That was the big thing for me. Weight started sliding off only then. Secondarily is nuts. I am losing again now that I have finally kicked those to the curb. I've lost 50+ pounds since June. I am exercising.
