My friend is a trainer. She works out consistently and has a well-planned diet. However, she seems to have an addiction to Diet Pepsi that makes me cringe.
She claims "zero calories, zero guilt" just as the marketing would leave you to believe. I try to tell her that it's a bad idea to be drinking diet pop on a regular but don't really have anything to back up my arguement.
To be honest, I just want to be right and win the arguement. Anyone have any ideas to help me outwit this little brat?
