What is the name of a children's book with two girls who can eat whatever they want?

I read this book back when I was in middle school and it's about these two girls in the future and they go to this machine on the street and they get a small dot on their wrist to lose weight, so they can eat whatever they want.





Eventually, they have done this so often, they have a bunch of these tattooed dots all around their wrists.

Lose Now, Pay Later" by Carol Farley

"Carol Farley's fanciful "Lose Now, Pay Later," describes two new stores at the mall--one that gives away free sweets and the other, a costly instant weight loss center"

"Carol Farley, "Lose Now, Pay Later". One day free candy is available at the mall. It's so delicious that weight obsessed teens can't resist it. Then stores open up offering to take your excess pounds for 25c a pound. Only a small boy thinks there might be a catch--maybe someone is farming humans?"
