Re: Put down the pie
"The amount of exercise needed to burn off calories simply makes exercise an unrealistic method of weight loss."
Well you can do it - I lost 35kg over ~3 years by just that. But you are quite correct it is a massive commitment and unrealistic unless your work/life allows for it or you're actually an athlete in training.
That loss BTW averages to just 250 Cals/day
(OTOH it's estimated that hunter/gatherers from 10000 years ago spent ~~1300 Cals/day in exercise - which very roughly equates to 0.15kg of fat)
