Recent research suggests a link between inflammation caused by visceral fat and Alzheimer's disease. Higher amounts of visceral fat lead to brain atrophy and inflammation. Visceral fat contributes to insulin resistance and inflammation in the brain, connecting to Alzheimer's. Controlling visceral fat is important for optimal brain health, involving factors like sleep, depression, exercise, and diet.

Quick takeaways
Higher levels of visceral fat in individuals in their 40s and 50s can lead to inflammation in the white matter of the brain, impairing communication between the brain and the rest of the body.
Managing visceral fat through exercise, reducing alcohol consumption, and adopting a diet of real foods can help maintain brain health and decrease the risk of Alzheimer's disease.

Link Between Deep Belly Fat and Brain Atrophy
A pilot study discussed in the podcast explored the relationship between deep belly fat, also known as visceral fat, and brain atrophy, particularly in the gray matter of the hippocampus. Individuals in their 40s and 50s with higher levels of visceral fat tend to have more inflammation in the white matter tracks of the brain. This inflammation impairs communication between the brain and the rest of the body. Previous studies focused on overall belly fat, but this study found that it is specifically visceral fat that is associated with brain atrophy and the development of Alzheimer's disease. Managing visceral fat through exercise, reducing alcohol consumption, and adopting a diet of real foods can help maintain brain health.
Importance of Controlling Visceral Fat and Factors that Influence It
Another study mentioned in the podcast emphasized the importance of understanding and controlling visceral fat for brain health. This study found that visceral fat is linked to lower volumes in multiple regions of the brain, including gray matter, white matter, and specific lobes. There are various factors that can influence visceral fat, such as sleep patterns. Both insufficient sleep (less than five hours a night) and excessive sleep (more than nine hours) are associated with increased visceral fat accumulation. Other factors include alcohol intake and fructose consumption from ultra-processed foods. Engaging in moderate to vigorous exercise and adopting a diet of real foods can help reduce visceral fat and improve brain health. Managing these lifestyle factors can contribute to maintaining cognitive function as individuals age.
