that’s always nasty, particularly since it is often accompanied by a reproachful look that insinuates that this is our fault.
I tend to first turn it around and ask whether THEY would have any explanation. Unless there is a medical problem that would explain all of it, an increase in body fat in a person exercising with some regularity probably also means an increase in weight. Clients, with proper introspection, usually will ‘fess up’ and really do not need to hear it from us.
It is a good opportunity to explain how relatively little exercise contributes to the overall equation of ‘energy in vs energy out’, and many exercisers fall into the trap of eating those 300 calories, proudly expended on the treadmill, a few times over in the course of the day. It’s also an opportunity of talking about NEAT, I call it the need to NEAT.
I am curious to read how my colleagues will chime in.
