The scary thing about travelling, is you won't know if you have gained weight or lost some.
There's no way to tell, you can be bloated for all you know.
It's a scary procedure, for those who know weights can't be controlled, you might end up returning to your home after one month of travelling gaining more than 5 kg.
Or losing more if I'm lucky, which I doubt. I did lose a lot more in Lao though, maybe I should stay in Lao for 30 days, and lose up to 10kg in that month. :D
That sounds like a healthy way to lose weight, and what a way to explore the country.
