Does being cold help lose weight?
I read this comment on a YouTube video showing body builders having breakfast:
Ice water. That's the key. Not just plain water - you gotta put ice in it. Otherwise your gains in the gym just go kaput. It's the secret of the pros. Especially during contest prep. Burns an extra 1000 cals a day of pure fat.
Obviously YouTube comments by random people who most of the time are just spewing nonsense is not to be trusted but this one really caught my attention because of the ramifications if it's true. So I rather ask the experts, is there any truth to this and if so why?
