2Kg isn’t unhealthily fast….
I lost 8 kg in two weeks last year…… OK I admit this was two weeks treking and climbing in the High Atlas so it’s not exactly a fair comparison!
High Altitude, 7 to 9 hours hard walking and climbing a day and only as much food as can be carried by our mule is, in some ways, cheating as it takes the will power requirement away from you – rather in the same way that an army drill sergeant makes exercise non-negotiable for recruits – once you’re in, you are going to get thinner!
Wish I’d used it to kick start my diet though as I’d be a hell of a lot better off and by now I’d be just getting nicely into shape, but then without my own personal drill sergeant I’m just going to have to drag my own arse out of bed i the mornings to go to the gym! 🙂
