This is a hard problem, as the article states. One of the biggest problems is that the "maintenance" level is a) extremely difficult to pin down on a good day, b) is different for everyone, and c) it moves every day. Let alone people who have other confounding medical issues like hypo- or hyper-thyroidism, diabetes, etc. Throw all that in and yes, the biological fact of "eat less move more" is true, it's also almost completely worthless for a very large percentage of the population.
