Excersise In the heat Of summer.

I walk about fifty minutes a day and I was wondering if I would lose more weight in the summer months more that the colder months due to sweating.

Sweating has no effect on fat loss - you could lose water weight, but it would come back as soon as you drank water again.

You might lose more weight in the summer because you chose lighter foods (more salads, less lasagna) or because you spend more time outside and active. But not due to sweat.

The reaso I was asking is because horse jockeys sit in sauna's for hours and often days to reach their riding weights.

So do wrestlers. But they are just losing water weight for their weigh-in. It has no effect on fat loss, and is temporary, not to mention potentially unhealthy (dehydration can be bad).

My husband once lost something like 12lbs in one day for a wresting meet - he missed the weight by half a pound, which was probably be a good thing, because he would have been too weak to compete.

edit: I've been corrected - it was 14 lbs, and he missed it by 1/10th of a pound.
