Does working out in hot weather burn more fat?

When it comes to working out, does working out in the heat cause you to shed a bit more calories and weight in turn? Or does it not have any effect on how much you burn? I know you'll probably lose more water weight, but could you also lose more weight too?

While your body is acclimating you will burn more calories trying to stay cool. Once the body is used to it though it will be like anything else. 

I do notice in my workouts on hotter days my heart rate runs just a little bit higher for the same amount of effort and of course I sweat a ton more the warmer it is. 

When working out in hot weather you tend to hydrate a little bit more then average so you do lose a lot of water and depending on how much you are sweating there is huge swings in water weight. 

Looking at my weight graph for the month I can tell when I ride my Peloton inside for longer sessions because my office AC sucks and the temp will quickly climb up to 95. I sweat no where near as much on my runs at a similar heart rate levels at 100 degree weather. I find it very strange. But anytime I do a long ride on the Peloton I can watch that water weight just drop off.

If you stay hydrated, I believe it does but if you are not drinking enough water, you might see the opposite! Because we tend to sweat a lot when it is hot and we are being physically active, you lose a lot of water and electrolytes. If they are not replaced, your body will go into a state of panic over dehydration and will begin storing more water which will cause the scale to go up, not down.

I never heard of such a thing but it is interesting what James and Emma both mentioned. 

You learn something new every day! I guess hydration is always key for weight loss though, hot or not!
