No, but at under 140 pounds I sweat 1/2 to 1/3 as much (8-12 ounces an hour) as I did (16-24) at 185-205 (confirmed by weight - I drink that much, and it doesn't change between before and after riding).
With more insulating fat between your blood vessels and skin less heat gets out so you sweat more. It's like when dried out thermal paste insulates your CPU and it overheats.
