3 doctors agree
In brief: They Shouldn't
Weight loss shakes should not affect the efficacy of your birth control pills, unless they contain some form of herbal preparation or medication.
However, i advise against rapid weight loss shakes, as rapid weight loss can be dangerous. One should not lose more than 2-3 pounds a week on a weight loss plan. Plus, if you rapidly drop weight, you will rapidly gain it back without lifestyle changes.
