Ep. 47: A Critique of The ROS Theory of Obesity (The Croissant Diet Part 1)

The Energy Balance Podcast

In this episode we discuss:

• The major issues with the ROS theory of obesity

• Why fat-burning is inefficient and doesn’t lead to healthy fat loss

• The real problem with PUFA (and why they don’t decrease ROS production)

• Why carbohydrates and insulin don’t cause fat gain

• How increasing cellular energy through efficient mitochondrial respiration is the key to healthy fat loss

Timestamps:

3:26 – an introduction to The Croissant Diet and Fire In A Bottle

10:04 – an introduction to ROS and the varying ROS-producing effects of fats and carbs

16:10 – the ROS theory of obesity, Randle cycle confusion, and how fat-burning causes physiological insulin resistance

25:30 – the effect of fatty acid saturation on ROS production when oxidized in mitochondria
