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.

Weight loss: Sometimes what is in the product can effect the BCP. The weight loss itself can effect metabolism of the pill.
