Okay, so instead let's look at people who have lost weight (well-trained pilots) trying to maintain their loss. They fail miserably. Very low success rate. Among a large population. So not a rogue pilot with a machine gun, instead the majority of successful weight losers.
The advice "eat less move more" is a proven loser. Not really even a question. Time to move on. Maybe low carb/IF/less time-consuming HIIT will do better. But we know move more, eat less has failed. Being more smug about the fact it would work if only all these dummy pilots would use it right isn't going to improve the public health success rate.
