Potatoes are loaded with potasium, too.
No offense - but it has never made sense to me to try to lose weight by limiting certain veggies. I am chubby b/c I ate too much pizza, cheesy dip, crap, cookies, cakes, cheese, sour cream dips, crap, chips, crap... etc.
I am not chubby from too many carrots! I think it is important to always maintain a balance. And everything in moderation and all that. If you sit down and eat 3 lbs. of carrot and a lb of potatoes... yeah, that would definately not help with weight loss.
I hate carrots... I wish I liked them. I can handle them in soups and stews when they are mushy and have no more flavor... All those vitamins and beta carotene.
