You quit, removed thousands of alcohol calories, and gained weight. This is common and there are specific reasons.
Why
Sugar replacement. Appetite returns. Metabolism adjusts. Emotional eating without substances. You are absorbing nutrition for the first time in years.
When to address it
Not in the first 90 days. After 3-6 months, when recovery is stable. Focus on adding healthy foods rather than restricting. The recovery community says: don't trade one obsession for another.
