Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Therefore, the investigators are interested in examining the metabolic response pre and post intervention to see whether these promising findings can translate into a healthy population. Furthermore, the investigators will be monitoring subjective appetite, energy intake and expenditure to assess whether there is any short-term adaptation to a specific feeding window.

Extended Evening Fasting
Participants will eat between 8am-4pm
Extended Evening Fasting
Participants will undertake 4 days of extended evening fasting (feeding between 8am-4pm). The participants will visit the laboratory on day 1, following a 16 h fast, where baseline measures will be taken and the response to a standardised meal will take place. The participant will also have an opportunity to feed ad-libitum before they leave the laboratory. The participant will continue to adhere to the feeding window on day 2 and day 3, although this will be in free-living conditions. On day 4, the participant will arrive back to the lab for post-intervention assessment, identical in format to day 1 with a metabolic assessment and energy intake assessment via a ad-libitum meal.
Control
Participants will eat between 8am-8pm
Control
Participants will undertake 4 days of a standard western feeding pattern (feeding between 8am-8pm). The participants will visit the laboratory on day 1, following a 12 h fast, where baseline measures will be taken and the response to a standardised meal will take place. The participant will also have an opportunity to feed ad-libitum before they leave the laboratory. The participant will continue to adhere to the feeding window on day 2 and day 3, although this will be in free-living conditions. On day 4, the participant will arrive back to the lab for post-intervention assessment, identical in format to day 1 with a metabolic assessment and energy intake assessment via a ad-libitum meal.
