Not sure if this has been said since I only read the OP.
I've had tremendous results going keto. The trendiness of keto and low carb is annoying, but the results really have been night and day for me.
I'm a very naturally lean guy with an insanely high metabolism, but have severe fatty liver and a stubborn inner tube that won't disappear. I'm also fairly small, so it really shows.
Now I feel mentally sharp and physically amazing and strong, and the belly is flat too! My whole life I've been foggy and fatigued. In the last few years, I had gotten to the point I didn't want to eat if I had to function, because every meal felt like thanksgiving and made me sick.
I Realized carbs were making me sick. I always felt better when I stayed hungry. So I cut down and it was magic. It really shows the chemical side of actual carb addiction. Once the body adapts a bit, pizza and burgers and cookies have ZERO allure and look like rat poison. I actually crave things like kale or lentils. Then If I slip up and eat some crap, the pathological hunger returns, and suddenly a Big Mac is like crack, and the thought of bland brown rice and fish gags me. It's really cool to be in the healthy biochemical state since the tendency to blindly gorge goes away for some reason. You start to see food as simple fuel instead of pleasure, but still enjoy good meals too.
Anyway, I'm a big advocate of ketosis, if used right with some objectivity. Some try to do it forever. I personally believe it's best to use it to recalibrate the body and purge fat until you are happy. Then transition back into a more conventional diet, keeping the emphasis on lean protein and veggies, but adding complex carbs like brown rice, sweet potatoes, squash, etc. But still keep them fairly low.
Just wanted to share my experience. YMMV.
