The data, starting with one person
Carb fasting's results begin with one person: over a year, the founder tracked himself with a continuous glucose monitor and a metabolic breath analyzer and recorded 21 lb of scale weight lost, including 23 lb of fat lost and 2 lb of muscle gained. This is a single-person anecdote. Individual results vary, and a member-cohort log is coming.
Our data starts with one person: the founder of carb fasting, who tracked his own year on the plan. His results are an anecdote.
One person, one year, measured
Over roughly a year of carb fasting, the founder didn’t just step on a scale. He wore a continuous glucose monitor to watch how his blood sugar responded, and used a metabolic breath analyzer to see which fuel his body was burning hour to hour. The headline numbers from that year:
| What he tracked | Result |
|---|---|
| Scale weight | 21 lb lost |
| Body fat | 23 lb lost |
| Muscle | 2 lb gained |
| Tools used | Continuous glucose monitor + metabolic breath analyzer |
| Sample size | One person (n=1) |
The fat-and-muscle split is why he tracked composition alongside weight. The scale moved 21 pounds, but underneath it he lost more fat than that and added a little muscle. That’s the kind of change you only see when you measure.
This result is unusually large. It’s one motivated person’s outcome over a full year. Most people should expect a smaller change, and individual results vary. Treat it as a single data point.
Why we’re calling this an anecdote
This is one person’s result. In research terms, it is an n=1 anecdote. One motivated founder tracking himself for a year is weak evidence, no matter how clean the numbers look. Individual results vary, and yours will too.
It would be easy to turn “23 pounds of fat, 2 pounds of muscle, measured with a breath analyzer” into a marketing promise. We’d rather tell you how much weight this first result can carry. It shows the proposed mechanism in one body.
What’s coming
A member-cohort data log is in progress. As more people follow the plan and agree to share their tracking, we’ll publish the full range of results. We don’t have those cohort figures yet. When we do, they go here.
For how we grade the published research behind all this, see the evidence. For the mechanism these numbers are testing, read the science.
