<p>You did one fast. That is not nothing and it is also not much. It is a data point.</p> <p>What it tells you:</p> <ul> <li>You can close the eating window for a stretch and nothing catastrophic happens.</li> <li>The hardest part is usually the 30 minutes before you expected to eat, not the hours after.</li> <li>How you feel when you break it tells you more about your plan than the fast itself.</li> </ul> <p>What it does not tell you:</p> <ul> <li>Whether you''ve lost weight.</li> <li>Whether this will work for 90 days.</li> <li>Whether you''re a "fasting person."</li> </ul> <p>The protocol is not one fast. The protocol is the same three lines, repeated, for long enough to matter. Treat this first one as proof you can do it, and then go back to the boring part, which is doing it again tomorrow.</p>
