Angela is joined by internationally renowned medical doctor and researcher Dr. William Li for an eye-opening conversation about metabolism, fat loss, and the science of food as medicine. Dr. Li debunks common myths, like the belief that metabolism “slows down” with age, and explains how excess body fat, not age, is the real driver of metabolic decline.
They also explore groundbreaking research on foods that activate brown fat, reduce visceral fat, and improve health span, offering practical, science-backed strategies you can use today.
KEY TAKEAWAYS
Metabolism Myths Debunked: Human metabolism remains rock-stable from ages 20–60 and only slightly declines after that. The real issue is excess fat, not aging.
Visceral vs. Brown Fat: Visceral fat harms metabolism, while brown fat is metabolically active and helps burn visceral fat.
Food as Medicine: Everyday foods like tomatoes, berries, extra virgin olive oil, and even coffee can activate brown fat and improve metabolic health.
Lifestyle Choices Matter: Stress, poor sleep, alcohol, and ultra-processed foods slow metabolism. With the right choices, 60 can truly be the new 20.
Personalized Health: There’s no one-size-fits-all prescription. How you live, eat, and manage stress determines how well your metabolism functions.
