ANECDOTE

15-Year Eating Disorder Journey

Michelle shared a 15-year struggle with anorexia/bulimia that peaked in university and nearly ended her life.
Yoga and mindset work ultimately helped her recover and shaped her coaching focus on nervous-system regulation.

ADVICE

Refer Out For Eating Disorders; Use Guardrails

If a coach suspects a true eating disorder, refer to therapy instead of pushing dieting tactics.
Use graded 'treat meals' and guardrails for those on the spectrum to regain food freedom safely.

ADVICE

Prioritize Functional Movements

Train functional movements: carry, push, and overhead work (or alternatives) to preserve independence.
These patterns support daily tasks like lifting, getting up, and placing items on shelves.
