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

After (189 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: 84 lbs. Total life gained: immeasurable. This isn't just about weight — it's about reclaiming your identity.

Anxiety increase on mental health: counterintuitive, but losing weight rapidly triggered anxiety for me.

This is exactly what I could not find anywhere else. Sending this to two other people who asked me the same thing last week.

Body image adjustment with mental health: I've lost 64 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.

My mood has been flatter since about month four and I genuinely cannot work out whether that is the drug, the deficit, or the fact that I no longer…

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.
