Soso Whaley experimented (and documented) eating only McDonalds food, but choose healthier menu items, like salads at lunch, not getting the larger sizes of portions etc..
She ate McD's for 60 days, not just 30 like the dummy. She lost 18 pounds and her Cholesterol went down 40 points.
But, again, it required making better choices of what to eat and how much.
Of course, not being as sensationalistic, not many news organizations covered it.
So, you can either be easily swayed by listening without thinking, or you can actually engage the brain, question and consider.
