Deep dives
Professor Giles Yo's Journey into Obesity Research
Professor Giles Yo's encounter at a dinner party sparked his interest in obesity research 20 years ago. This encounter challenged the notion of obesity being solely a choice. His groundbreaking research now shows that obesity is a brain disease influenced by genetics, where some individuals face challenges in controlling their food intake.
Obesity as a Brain Disease and Genetic Influence
Research conducted by Professor Giles Yo over three decades revealed that obesity is primarily a brain condition. The discovery of mutations in genes like leptin highlighted the brain's role in influencing hunger and food consumption. Furthermore, genetics play a significant role in determining an individual's susceptibility to obesity.
The Impact of Genetics on Obesity and Potential Treatments
Genetics play a significant role in obesity, with heritability accounting for 40-70% of fat mass variation. Professor Giles Yo emphasizes the importance of genetic factors in determining body weight. New drugs like Wigovi and Zepbound target brain signals to reduce food intake, offering potential treatments for obesity.
Redefining Obesity as a Disease and Policy Considerations
Professor Giles Yo advocates redefining obesity as a chronic brain condition that influences health. He encourages policymakers to address the socioeconomic factors linked to obesity by making healthier foods more affordable and accessible. He emphasizes the need for a holistic approach to combat rising obesity rates worldwide.
Reframing the Discussion on Calories and Nutritional Content
Professor Giles Yo challenges the conventional focus on calorie counting, emphasizing the importance of food quality over quantity. He advocates for considering nutritional content, protein, fiber, and micronutrients in food choices. He encourages a shift towards healthier food options without demonizing food manufacturers.
Promoting Optimism and Change in the Battle Against Obesity
Professor Giles Yo remains optimistic about shifts in the societal conversation around obesity. He emphasizes the need for comprehensive approaches to obesity treatment, including policy changes and innovative treatments. Despite challenges, he envisions a future where obesity is tackled through a combination of individual efforts and systemic changes.
The Role of Food in Promoting Joy and Healthy Eating Habits
In discussing comfort foods and the joy of eating, Professor Giles Yo highlights the personal and cultural significance of food. He acknowledges the societal impact of food choices and calls for a balanced approach to nutrition. He values the pleasure of eating while promoting self-awareness and healthier food habits.
Upcoming Guest and Interactive Segment

How much do our genetics determine our destiny when it comes to how much we weigh? Cambridge geneticist Giles Yeo says your genes play a bigger role than you might think. “In casino terms, the house will always win if the die is weighted just a little bit one way versus the other.” On today’s Chasing Life, Professor Yeo, a pioneer in the field of obesity research, joins Dr. Sanjay Gupta to explain his ground-breaking research into why some people are genetically predisposed to eat more, and why it’s still so controversial to classify obesity as a “disease.” Plus, Professor Yeo shares how to treat and prevent obesity, a condition that impacts more than 40 percent of Americans, and counting.
