No clue... I actually started my journey over the summer when we were abroad for work so I didn't have access to a scale for about 2 months. Before I left the highest post partum weight I saw was 225lbs but then when I got there I was eating like crazy for about a month (before I gave up sugar) so up until that point I might have been more, who knows? I gave up sugar and was exercising the second month there and weighed in at 218lbs (so a 7lb loss for the first month) but I could very well have been at a higher weight when I made those changes.
I've never actually calculated that before, wow, and I definitely never thought I lost 7lbs in one month! I certainly haven't repeated that since then (more like 2-4lbs/month with some months not losing anything at all).
