Basically, she’s just some food nazi nutter who can’t leave any one else alone. She’s called the obesity problem in the U.S. “a matter of national security” and once got thrown out of a YMCA for trashing an ice-cream bar. She’s also tried to get the Girl Scouts to stop selling cookies, and considers junk food a form of child abuse.
I think her zealot stand is as much about getting fame as it is genuine nutburger-ness, but either way, she’s an annoying twit. Here’s a long article about her:

Edit: I don’t know who bankrolls her, but it might be in the article I linked to.
If Obamacare ever comes to pass, people like her will rush to the top echelons of power and ask to play the puppeteer. Navy SEAL enlistees will have it easier since all they have to do is say “I quit!” and ring the bell three times...and they get sent to more traditional jobs. Not so with the rest of us who will be taxed, imprisoned (debtors prison), etc. if such women hold power.
If she is so obsessed with staying fit and forcing everyone else to stay fit, let her join the Marines and be a drill sergeant.
