Whether we are in a caloric deficit or excess the main determinant of body composition is hormonal status. In your case a youthful hormonal profile was likely the reason for maintaining your leanness. Others of the same age are obviously not so lucky. If the case of the paleo eater vs. a high carber, in general the balanced, low glycemic load paleo eater is going to show better hormonal control and consequently better body composition. A caloric excess may be frittered away by uncoupling proteins in the mitochondria. Food is converted to waste heat, however this will only work to a point.
