Most people still believe weight gain is simply about calories.
But if calorie restriction alone worked long-term, why do so many people struggle?
In this conversation, Dr. Jason Fung sits down with Julia from Ancestral Supplements to explore the hormonal model of weight gain, insulin, ultra-processed foods, and how modern eating patterns may influence metabolism.
Topics discussed:
• Why “calories in, calories out” may be incomplete
• Insulin as a key metabolic hormone
• How processed foods can affect hunger and satiety
• The difference between whole foods and refined foods
• Understanding insulin sensitivity
• The role of nutrient density in traditional diets
Weight regulation is complex and involves more than simple math. This discussion explores how hormones, food quality, and dietary patterns may play a role.
If you found this conversation helpful, consider sharing it with someone who may benefit from hearing it.
