I love seaweed; let's just say if I ate it, I would seriously lose a lot of weight, because it had an instant GI effect on me . Not good.
I eat good, healthy food and I also tend to gain in the winter, if I don't watch it. If I ate everything I craved, I estimate an extra 5-10 lbs if I didn't pay attention. The older I get, the less carbs I can eat. But, once the cycling season starts, it's less of a concern. And, I'm still very active in the winter.
Lisa, you've seen me eat... you know I'm not someone who totally restricts my food!
