    2000 kcal/day x 1.5 days = 3000 kcal

    One pound of fat contains about 3000 kcal, so if you didn't lose any lean body
    mass, you'd lose about 1 lb. You will, of course lose some lean body mass,
    and lean body mass is heavier per kcal than fat, so the 1 lb. is probably an
    underestimate.
