Further to what Steve said on this issue, he's right. The overall increase in
calories burned due to eating more frequent and smaller meals isn't as significant as some of the other post metabolic benefits, of say, exercise.
But the basic point is correct - the simple digestion of food contributes to metabolism as your
body has to has to create digestive enzymes in your stomach, intestines etc. to digest your food. So, the more often you eat ( i.e every 2.5 hours or so...or 5/6 meals a day ) and the more food you eat ( within reason
) the more you'll be bumping up your digestion metabolism. It's not a lot in terms of a % of your overall maintenenace
calories mind you, but it's more so than if you only had 1, 2 or 3 meals a day of even less food of smaller portions during those meals...which would only serve to lower your digestion metabolism.
But every little bit to boost metabolism helps !
