Mashed Potato "No nutritional value"??!?!?!? - CLARIFICATION!!!

couldn't have explained it any better.  I'm not good at teaching so when I explain things it doesn't come out right. 

I agree about eating habits and not changing them.  I found that in the beginning I would come up with excuses and justifications to eat things I knew were bad.  I see that now.  The way I feel is why kill myself with all this exercise and then go out and eat burgers and fries???
