Well, perhaps my post was mildly facetious. Just that going by my recollection of the period I was monitoring my food intake, 2500 calories per day didn't seem that hard. Though having consulted the spreadsheet I kept in order to double check, I have to admit that it looks like it isn't that hard to eat less either :)

Snacks can add up surprisingly quickly so if you do have a shortfall I'm not sure it's necessary to resort to eating sugar. For example, 2 bananas and a tin of salmon will be something like 500 calories. That's 20% of your budget right there.
