There are zero legitimate studies that show any sort of link between sweat loss and weight loss.
That being said, it's likely that the days you're sweating harder are also the days that you're working harder and therefore burning the most calories...which will lead to weight loss.
Simply not so. Again, my experience. I work harder on the bike on cold days for the simple reason that punching a hole in colder air takes more watts.
