I'm no keto expert, but I think you can do it in a lighter form that doesn't reach the ketosis trigger point, and still get a lot of benefits. If that should rightfully be called a "keto diet" is a linguistic question i don't worry much about.

Back when I switched to the paleo diet some 10 years ago, I was ready for a huge fight with my cravings as I gave up all the sugar and grains etc. But nothing of the kind happened. I just started eating other food that I liked just as much, and felt fine. Lost 25 pounds over 6-9 months.

Maybe it was unusually easy for me. And paleo does allow some carbs, though I definitely cut down a lot.

Agree 100% about your exercise point!
