Quick question - did he do a totally clean induction? I mean no junk food, or low carb junk food at all? Did he stick to the veggies, meats, fat etc?...maybe there were some hidden carbs there somewhere...and the water is so important..but tht said, the meds may have played a part too..what you can do is write or email directly on the Atkins website for advice..they are really good about responding!
