Cancer website with eating/weight loss tips? -

I found this site a couple months ago, and now I cant find it...It was a website with information on cancer. It had a drop down menu with activities (biking, walking, cleaning the house, etc) and when you clicked an activity, it would tell you how many calories you burn per hour doing it. Also, it had a section where you enter your height and weight, stuff like that... and then it would tell you how many calories your eating per day in order to weigh as much as you do, and how many calories you need to cut out in order to lose weight.Does anyone know which website im talking about?Any help would be greatly appreciated!Thanks :)

i think it is mypyramid.gov
