Who is behind this

Greg founded Freedomology after building several companies and learning that money alone does not make a life free. He wrote The Fat Switch after a year of carb fasting that he tracked with a continuous glucose monitor.

The year he tracked

Greg ran carb fasting on himself for a year and tracked it with a continuous glucose monitor and a metabolic breath analyzer, watching in real time when his body switched from burning carbs to burning fat. He lost 21 pounds of scale weight in that year. That is one person's result, and it is the only result this site reports; the data page shows what was measured and how, and the results page explains why we do not publish testimonials.

Why the plan exists

Keto and calorie counting both work until people stop, and most people stop. Greg loves carbs and did not want to give them up, so the plan he could keep was one with two kinds of day: fast from carbs today, eat them tomorrow. He wrote it down as The Fat Switch, which is free.

Who publishes the site

Freedomology is a personal development company founded in 2022 by Greg Clement and Tony Allen. It runs H40, a paid 40-day health program in which carb fasting is one of the pillars. This site does not feed that program: the only email we send is the book and the occasional carb fasting update, and the form says so.

How the site is written

Every health claim links to a study with a DOI or PMID, and each study's design and limitations are listed on the evidence page. Pages carry the date they were last changed. We do not invent people, quotes, or numbers to fill space, and we do not call a page medically reviewed unless a licensed clinician reviewed it. The details are in how we research and the editorial policy.

Nothing here is medical advice. Talk to your clinician before changing how you eat, especially if you take medication that affects blood sugar.
