I am taking this as an early win.
A few years ago when I first came to Thailand for an extended period, the diet was not taken seriously, eating the naughty snacks and having fizzy drinks, it took me at least a month to shed any weight.
This trip is different, from day two (day one I had durian!) I took the diet very seriously and shed 6 kg in the first 6 days. Some of this could be water weight, nonetheless, I am using this as a positive booster.
