Atkins has worked great for me, but I I think the best plan for anyone is the plan they feel they can stick to best . I really think the most important thing for me--and I would imagine for just about anyone with PCOS or insulin resistance--has been coming off of sugar altogether. I truly believe my sugar addiction over the years has been my main obstacle to weight loss in the various plans I've tried. Once I started to make a little progress, that little white demon always kicked in with the cravings and ruined everything.
