What about my comment, in which I said that I have successfully used and advocate for keto, makes you think I was talking about "traditional dieting?"
Keto is challenging for most people, too. I agree it's much easier than how most people attempt to do caloric restriction, but it still is nowhere close to taking a shot.
Eating out at restaurants can be challenging, mixing keto with e.g. vegetarianism can be challenging, certain social gatherings (like holidays) can be challenging, the brain fog (temporary as it is) can be challenging, etc. etc.
Again, none of this to suggest semaglutide et al. are without side effects or difficulties, but things that require willpower are definitionally hard, and keto is definitely one of those things.
