Carb fasting came out of the same realization most lasting things do — I was tired of the alternatives. I love carbs, and I hated the idea of giving up the foods I love, so keto and the usual restrict-forever diets were never going to last. Carb fasting was the approach I could actually live with: fast from carbs on some days, eat them on others.
I spent a year testing it on myself, tracking my response with a continuous glucose monitor and a metabolic breath analyzer to watch, in real time, when my body switched from burning carbs to burning fat. Over that year — the only change I made — I lost 21 pounds of scale weight: 23 pounds of fat lost while gaining 2 pounds of muscle. That's my own result, and individual results vary.
I wrote it all down in the carb fasting book, which is free. Thousands of people in the Freedomology community now run some version of this, and this site is where the whole protocol lives in one place — the what, the how, and the why.
