Infra red eh? Just like sitting in front of an electic bar fire.
I'd be careful you don't get burnt, literally or money wise.
Can't say I've heard of this treatment before, but I would be wary of claims of losing so many calories so quickly. That, I believe, could only be achieved through profuse amounts of sweating (which is probably where the "detox" element comes from), but I'd be concerned about heat stroke etc if it's that "effective".
Have you ever tried sitting in a sauna for 1/2 an hour? If it's a good sauna, 15 minutes is a good session. 1/2 an hour can make you feel ill if you're not used to it.
I'd say, check up on it first and approach with caution.
