You don't often hear about anyone losing weight by eating at McDonald's. But John Cisna did. After eating exclusively off the restaurant's menu for 90 days, the former biology teacher dropped 37 pounds and four waist sizes, and his cholesterol went down as well. Cisna now travels the country to different schools as a brand ambassador for the fast food chain, endorsing healthy eating habits.

If the term "conflict of interest" just came to your mind, you're not the only one.

"I'm not endorsing fast foods," Cisna says. "I'm endorsing that kids need to start using critical thinking skills when it comes to making the right choices of what they eat."

But some parents think Cisna's message is just one big McDonald's ad in disguise. One mom, Bettina Siegel, took to to file a petition asking the company to keep its infomercials out of schools.

For its part, McDonald's says kids are eating fast food, so educating them on how to make healthy choices is valuable. The company does not plan to drop Cisna's program, which was presented in 90 schools across the U.S. this year. No financial assistance was provided to schools who booked Cisna's talk.

Cisna says the key to his successful French fries and burger diet was keeping his total daily calorie intake to 2,000. I'm left wondering: What did Cisna eat before his McDonald's diet experiment if those food offerings actually yielded an improvement for his health?!

What's your take? Are Cisna's talks helpful or hypocritical?
