Long term, that's a terrible strategy.
Fella I know went juicing. He'd seen some ridiculous advert that said if he only ate orange peel for a month or something, then he's lose ten stone.
I'll try to find the advert.
Well, indeed he did lose quite a lot of weight but there's a sugar molecule that binds with water. @Tinytom
will probably know what it is, I can't remember. The thing about it is that if you cut the carbs, you burn the sugar. Each sugar molecule binds with like, five water molecules. No sugar - nothing for the water to bind to and you lose weight. Lots of it - fast. He was shedding pounds a day.
The thing is that sooner or later, you'll come off your diet and start doing the stuff that made you fat again - and bada bing, you'll probably be worse off than when you started.
Anyway, back to ole matey... sure enough, it was pretty much the case that he ate one pie and put all the weight he'd lost back on in an instant. The pie replaced the sugar in his muscles and he retained every drop of water that he drank for a couple of days.
Last I spoke to him, he'd been doing this ridiculous juicing thing for getting on a year and was heavier than when he started.
Nah, can't find the actual vid he'd been watching but there's a ton of bullshit here.
