I wanna know...sweating in there can it make you lose a considerable amount of weight? because I mean in order to lose weight you have to sweat, I am already doing some cardio (alternate jogging-speed walking around 45 mins daily) but what if i spend 15 minutes in a saunatoo? Does sweating in there make you lose weight?

ugh I meant to say sauna...

You might lose water weight but you'll gain it back as soon as you rehydrate yourself. And if you don't rehydrate yourself you'll have less energy and your body won't work as efficiently which will impair your ability to burn fat, which actually stays off. I don't think losing weight from sweat actually makes a difference in your appearance anyways.

but isn't that how you lose weight I mean activating your metabolism so it sweats, takes out toxins and excess water.
that is basically what doing cardio does to you besides the whole speeding up metabolism part, you do it to sweat out the weight

It's not the sweating that makes you burn calories in cardio, it's the constant movement. Your body has to burn energy to make your muscles move, your heartbeat goes faster to supply your muscles with blood because oxygen is also needed to release the energy in glucose (or whatever your body is burning for energy), and the energy expended raises your body temperature so you sweat. Sweating itself doesn't burn calories when the heat is from an outside source. You'd actually be better off sitting somewhere cold so your body has to burn energy to stay warm.
