I know it sounds crazy, but research confirms that lounging in a hot tub for an hour burns the same number of calories as a 30-minute walk!  Look it up! We’re not talking about weight loss due to dehydration, we’re talking about actual calories burned!

The scientific journal Temperature. explains that this “passive heating” phenomenon increases your heart rate and speeds up your metabolism to create a similar physiological effect to going for a stroll in the park.

However, so far there’s no scientific evidence to suggest that spending the night in a hot tub will help you fit into that little black dress the next day.
