peterva, you don't need to go on a tv show to implement the same ideas and practices they do. you can start by walking for 30 minutes

3 nights a week and finding ONE way to changed your diet, such as reducing the amount of soda pop you drink a day.

after you adjust to those changes, increase your walking to 4 or 5 nights a week and and find another way to change your diet.

it is a gradual process!
