INSIGHT

Causes of Obesity

Obesity is caused by overeating or hormonal imbalances, according to two competing models.
The energy balance model suggests overeating leads to fat storage, while the carbohydrate-insulin model posits that metabolic dysfunction causes overeating and fat storage.

ANECDOTE

Dr. Magkos's Bread Consumption

Dr. Lyon recalls Dr. Magkos's past eating habits, where he would run for hours and then eat an entire baguette.
This anecdote illustrates that even experts can have seemingly contradictory dietary habits.

INSIGHT

Multiple Factors in Obesity

Several factors contribute to obesity, including genetics, environment, viruses, and contaminants.
Human metabolism may have changed before the rise of the current obesogenic environment.

In this episode of The Dr. Gabrielle Lyon Show, I sit down with Dr. Faidon Magkos, a leading expert in obesity and metabolism at the University of Copenhagen, to tackle one of the most debated topics in nutrition science – the root causes of obesity. We dive into the contrasting theories of energy balance and the carbohydrate-insulin model, shedding light on what the latest research reveals – and what remains unknown. Dr. Magkos also discusses how environmental factors, genetics, and muscle health shape metabolic outcomes.

Together, we discuss:

The real drivers behind obesity – is it overeating or hormonal imbalances?
Key differences between energy balance and carbohydrate-insulin models
Why obesity research still faces major limitations in human studies
The role of muscle and lean mass in metabolic health
Practical insights for diet design and weight loss strategies

If you’ve ever wondered about the science behind weight gain or how to create a sustainable, healthy diet, this episode breaks down the complexities with expert clarity.

Heads up! The audio quality in this episode isn’t perfect, but the insights are too valuable to miss. Thanks for sticking with us – you’ll want to hear this!
