The thing that people seem to always miss on these threads is who you are and from where you are starting.
If you're an obese pie stuffing slob, then eat less move more is indeed far better than some magic pill diet that you think is going to do all the hard work for you.
If you're a casual sportsperson with a few lbs and a few indulgences, then, eating less and moving more could still work - become a bit less casual and indulge less.
However if you're training for a specific goal and already train and eat well, then there may be certain ways to maniuplate your metabolism to lose more weight and/or get a training benefit.
In all of those cases though, understanding how your body actually works beyond the oversimplistic ELMM (and it is oversimplistic, that's clear if you read a bit more) may well achieve quicker and more permanent results. Depending on your personality and brain of course.
