Positive side effects of mental health that surprised me: Clearer skin — inflammation reduction improved my rosacea Better sleep — weight loss…

Before/after narrative for mental health — one year in:

Before (266 lbs): Winded climbing stairs, chronic back pain, pre-diabetic, on 3 medications, dreaded mirrors, avoided photos, social anxiety about my weight.

After (191 lbs): Run 3 miles regularly, pain-free, A1C normal, down to 1 medication, bought a swimsuit for the first time in a decade, actually enjoy being photographed.

Total weight lost: 96 lbs. Total life gained: immeasurable. This isn't just about weight — it's about reclaiming your identity.

Genuinely useful, thank you. I had the facts and not the framework. Sending this to two other people who asked me the same thing last week.

Body image adjustment with mental health: I've lost 90 lbs but when I look in the mirror, I still see my old self sometimes. "Phantom fat" is a real phenomenon.

My therapist specializes in body image issues with weight loss patients. She says it can take 12-18 months for your brain's body map to update. In the meantime: take progress photos (your eyes lie but cameras don't), try on old clothes, and be patient with yourself.

The weight came off and the harder part started, which is not what any of the material I read had prepared me for.

One year anniversary on mental health — reflections:

What I wish I'd known: the side effects are temporary, the benefits compound over time, protein is more important than I thought, and the mental health aspect needs as much attention as the physical.

What surprised me: how much my relationship with food changed, the cascade of health improvements beyond weight, and how supportive this community is.

What I'd do differently: start therapy earlier, prioritize resistance training from day 1, and stop comparing my progress to others. Everyone's journey is unique.
