I wonder if the information can be considered the whole picture, though, as I think a more accurate look would be what they weighed when they began the position/received the promotion/etc. When you think about the normal C-suite job, there isn't much physical activity but there is a lot of late night take out, long lunches, bad sleep, travel, and general body-beating. I wonder if the weight came on before or after, which would skew the finding if you're looking for why overweight women are less likely to reach that position than overweight men...
