Nice resource @Dominique

Here's a sample article from another free site that also discusses the problem with calories-in-calories-out.

The entire site is full of interesting stuff, some of which wanders into semi-experimental diet methods. The physician/author deals mainly with seriously overweight/unwell people in practice, but the foundation information is presented in a fun and authoritative manner.
