There are days when my kids just won't touch their meals no matter what incentives I offer (within reason). You know, those days when they seem to have a mind of their own and nothing appeals to them? On such occasions, I just ensure that the meals are especially nutritious, and pack it with all the healthy stuff I can think of. That way, even if they just pick at the meal, they still get most of the nutrients they need. I also make it a point to not give in too easily - like if they say they're hungry later, they know where the leftovers are, ha! But I do draw the line at spoiled appetites, and will usually offer some snacks an hour or so later if they haven't begged for them already.
