well just returned and as usual, the best advice is this 'EAT WHEN YOUR HUNGRY'.
seriously, who has time when touring to literally count calories during every day?
haven't weighed myself yet but i think i lost about 3 - 5 kilos.

i lost some extra fat on my stomach and now i'm ripped again which is nice
i guess my question from the beginning was not so much as a practical one as to just get a ball park figure so i can tell people a number before the trip started.

thanks for the advice everyone!
