During a weight loss period, your body's acid level is probably not one of the vitals you track on the way to the gym. Enter the pee-strip diet. A new diet has emerged that requires peeing on a strip of paper, which is available at most pharmacies, to test pH levels. Does it work? Well, this diet has been around for a few years but has gained more buzz recently. Celebrities such as Jennifer Aniston, Kelly Ripa and Gwyneth Paltrow have embarked down this road. Some dieters are even having pee-strip contests to see who achieves their more neutral pH level. Crazy right?
