Apple Cider Vinegar Diet

Starting a diet today, a girlfriend of mine told me she takes shots of "Spectrum Apple Cider vinegar" everyday, in 4 weeks she lost 15 lbs. Please note this girl is only about 115 lbs and 5'3" now she is down to about 100 lbs. Yeah.. I know you are going to tell me she is not over weight why bother with the diet. What would a BIKINI model do? Plus no chemical just natural stuff so I decided to give it a try. As of today, I weight 126 lbs and 5'5", I will let you know the results every week to see if I lost any weight..~ peace
