The perception of banting being 'boring' here I think is rather tightly connected to the number of times you've had to endure a banting story. If every second person had conquered Mount Everest and told you about it, I imagine that story would become 'boring', too.
Is Mount Everest boring? Certainly not. Does hearing about it a lot make it more boring? Perhaps.
By the same token, banting isn't boring, and most of the people who tell you their banting stories probably aren't boring. Sure, you can't directly compare the feat of losing a few kilograms to that of conquering Mount Everest.
But here's the catch: so many hopeful diet-followers and people who genuinely have had real problems with weight feel like they've conquered Everest. They've been stuck at the base trying to get to the top, and banting has made the pinnacle possible.
Every day, every one of us fights a little battle. To others, it's a boring one. To us, it's significant.
No, I do not bant. I'm far too skinny as it is. But don't knock banting, or the people who can't stop talking about it. Those who carry on and on, fair, that's just a flaw of theirs. They'll tend to tell other stories over and over, too.
Have a good day. Don't be too quick to judge!
