Penn Researchers Identify Brain Circuits That Increase Risk for Obesity

These findings underscore that some individual’s brains can be fundamentally different in regions that increase the risk for obesity.

WeightControl.com:  What is the background for this study? 

Response: The dorsolateral hippocampus (dlHPC) is located in the region of the brain that processes memory, and the lateral hypothalamus (LH) is in the region of the brain that is responsible for keeping the body in a stable state, called homeostasis. Previous research has found an association with loss of function in the human hippocampus in individuals with obesity and related disordered eating, like BED. However, outside of imaging techniques such as magnetic resonance imaging (MRI), the role of the hippocampus has been difficult to study in humans with obesity and related eating disorders.

Time Restricted Eating Reduced Glucose Levels Study of Type 2 Diabetes

​For our study, the time window in which participants were allowed to eat was delibarately set to daytime, with the last meal being ingested at 6 PM the latest. We did this so that the time-window fits in the natural, internal day-night rhythm of humans.

WeightControl.com:  What is the background for this study?  What are the main findings?

Response: In our modern 24h society, most people spread their food intake over at least 14 hours per day. As such, they lack a pronounced fasting state during the night and energy stores are hardly being depleted. Here, we wanted to re-store this pronounced overnight fast in people with type 2 diabetes, by limiting their habitual food intake to a 10-hour daily time window (time restricted eating, TRE) for a period of 3 weeks.

We hypothesized that the utilization of energy stores during the night would increase the need to re-fuel these stores with the first meal of the day, and would therefore result in a better energy uptake via the hormone insulin; i.e. would result in better insulin sensitivity. Although we did not find insulin sensitivity to be increased with TRE, we did find that fasting- and 24h glucose levels were decreased as compared to our control condition, in which participants spread their habitual food intake over at least 14 hours per day. Moreover, our volunteers spent more time in the normal glucose range, whereas the time restricted eating regime did not increase the time spent in hypoglyceamia.
