As I never lost the 4 extra pounds that I gained, I decided to try the vinegar again. I tried it for 2 days, this time with only 1 teaspoon with 8oz. of water and gained exactly one pound each day (up to 127 lbs)! I've been off it now for two days and my weight has returned to 125 again. I would have gone longer just to make sure, but I feared not being to lose the weight again. I am a 27 year-old female who makes healthy food choices most of the time and exercises 3-5x per week. I know that I do not consume enough calories to be gaining a pound per day from what I eat. I believe that the ACV must be interfering with my hormones somehow. Another reason I think this is because my menstrual cycle was affected (I started bleeding moderately, even though my period officially ended a week ago).
Interestingly, yesterday a friend directed me to some literature about blood type diets. My type is AB. In a book that I read, it said that people with this type should avoid all vinegar and pickled foods. It also said that AB's are predisposed to menstrual problems and migraines...conditions that I'm chronically plagued with. I'm going to take some time look to into this information and test out their eating plan. Hopefully it works. Either way, I won't be turning to ACV again for help with weight loss.
