GP describes the keto diet, which worked for me too. About the cholesterol, better read up on it. The hype about cholesterol has gone out of control. There are multiple types of it, and earlier research wasn't as conclusive as everybody thought. (Just like saturated fats by the way.)
Low carb diet lowered my weight by 25 lbs, made my GERD disappear, no more taking omeprazol 'for the rest of my life', my gallbladder stopped acting up, and I have more energy as if I was 10 years younger.
This was enough to convince me that I'm not going back to eating carbs as I did before.
