A study conducted on mice revealed that restricting their feeding window to eight hours even on a high-fat diet could result in weight maintenance or loss. Additionally, the mice that followed this feeding pattern showed improvements in their health markers.
This podcast discusses the history of time-restricted feeding and the current literature on intermittent fasting largely attributed to the work of Sachin Panda. It also touches upon studies conducted on mice's eating habits, where they tend to eat less when fed during specific hours.
A study showed that mice who ate a highly palatable, high fat diet within an eight hour feeding window of a 24 hour cycle maintained or lost weight over time. The eight hour feeding window was chosen due to the demanding nature of the study, rather than due to any inherent importance of that particular timeframe.
