How Overeating Rewires Our Brains – The Neuroscience of Obesity, Weight Gain, & Weight Loss

Some of the earliest changes in obesity are invisible – and they start in the brain. Of particular concern, many of the brain changes that accompany obesity bear striking resemblance to those that occur in brain injury. In this episode, we discuss how overeating can lead to inflammation and neuron dysfunction in specific parts of the brain that control appetite and energy regulation. We review the neuroscience of appetite regulation, energy expenditure, and body fat regulation. Topics include hypothalamic dysfunction of body fat regulation, leptin resistance, neuro-inflammation, and physical changes in the hypothalamus involving microglia (the immune cells of the brain). We also review what is known about avoiding and reversing these changes.

How Super-Athletes Use FAT for Fuel

In this episode, we discuss fat through the lens of performance and survival, and what happens when we push our energy systems to their limits. We also talk about how our bodies make adaptations via exercise to improve our ability to “burn” fat for fuel, and how our bodies conserve fuel during times of negative energy balance. Lastly, we preview the role of fat as an endocrine organ and the importance of its communication with the brain, as well as the critical role of exercise capacity for our future health.
