the sad thing is given my height, weight, age and
average activity level(minimal), I shouldn't be eating more
than 1,800 calories daily 
and 1 large bag of chips is like...1,400 calories LOL
For my stats, assuming a moderate degree of activity level, I
can take up to 2200 calories per day.... at least, that's what the
online tools say....
That said, I always calculate my output as (BMR + exercise
output).... energy output for things like everyday lab work is
disregarded to compensate for any discrepancies in the calculation
of my food input.
And let's face it: no matter how much you track your calories,
there will always be some discrepancy. No two nasi lemaks are the
same, for instance: one hawker may give a bigger portion, while
another hawker may dilute the coconut milk....
