It seems to be all the new rage of current medical studies. Awhile back (when I first started here) I had asked how that TOM effected weight loss. I got a lot of postive responses and a lot of varied responses as well.
While doing more research on it (I'm such a nerd) I've come across a couple studies that have actually indicated that the week prior to TOM women's metobolic rate increases, which is why we feel hungrier. If your trying to lose weight with a restricted calorie diet and you can stay OP during this time you'll actually increase your weight loss compared to other weeks.
I attached to two sites I'm using as a refrence here, but I'm posting this I guess because it gives me a little extra encouragement to avoid those PMS cravings and sloath-ness. And it makes me hate my period just a little less, not much, but a very itsy bitsy tiny amount less.
