It works for me. I hit upon this about four years ago. I refer to this as low tech solutions to nasty little problems. And this couldn’t be any more low tech. Just stop eating stay away from carbs. Add in butyrate. I never went into ketosis but I was doing strong intermittent fasting. I had a 30% improvement in my kidney function and my kidney doctor never asked me what I did. Viome has helped me with this.
the key to getting more butyrate in your life is to eat keto bread. that bread is made of flours like almond flour or coconut flour or any of a dozen different flours that the stomach and small intestine can’t digest. the flours are all digested in the large intestine and bowls by the bugs. keto bread is basically bug food. bugs make the butyrate and other short chain fatty acids that the body needs.
There’s a growing body of evidence that US diet just doesn’t include enough bug food.
