There seems to be a plateau around your "normal" lifestyle on which the body adjusts to small differences in calories in and out.

"If you eat a little too much, the body cranks up the burn rate a little: you feel warmer and more inclined to run up a flight of stairs rather than walk. If you eat a tad less than ideal, you may feel chilly and inclined to curl up with a book under the blankets and get a little extra sleep. [...] To achieve weight loss, you have to reduce what goes in below your capacity to adjust by banking the metabolic fires, forcing your body to tap its reserves[.]"
