In this episode, Matt sits down with Shannon Anderson, a 63-year-old executive recruiter who spent decades mistaking good looks for good health. Shannon's 46-year journey from eating disorders to true health is one of the most honest, inspiring conversations we've had on the podcast. Shannon grew up in the era of Jane Fonda and extreme dieting. She struggled with bulimia and anorexia for years, thinking she'd "invented" the perfect solution to looking good while eating whatever she wanted. It worked until it didn't. At 60, her body stopped performing. She couldn't lift a laundry detergent box without two hands. Her brain was slowing down. Despite going to the gym regularly, she wasn't making progress. That's when she discovered Optispan, and everything changed.
