I mean,  they do have half a good point.. there are a lot of really really shitty businesses out there peddling horrible weightless equipment and eating plans that don't work and frustrate the ever living fuck out of personal trainers and nutritionists. But still,  a basic gym membership is about $15 a month for planet fitness and people will spend that much on two days of junk food,  and I'm assuming very moderate consumption not even land whale levels.
