Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study compared the metabolic response to three different eating windows (morning fast,12pm-8pm; evening fast, 8am-4pm; control, 8am-8pm).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Humans have evolved as a diurnal species, internally governed by the circadian system, which dictates our hormone regulation. 'Chrononutrition' is a sub-discipline which combines food timing with circadian physiology. The most popular method of time-restricted feeding in the UK is to skip breakfast. However, data from several meta-analysis have shown that skipping breakfast is associated with weight gain and insulin resistance, likely due to eating later into the evening/night and therefore, out of sync with our circadian rhythm. Recent research has shown that skipping dinner (evening fasting) has improved markers of cardio-metabolic health in clinical populations, although these are typically from longer-term studies. Despite these promising findings, it is not yet known whether these findings are population specific.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Evening Fasting

Participants will undertake acute evening fasting (feeding between 8am-4pm)

Group Type EXPERIMENTAL

Evening Fasting

Intervention Type BEHAVIORAL

Participants will undertake acute evening fasting (feeding between 8am-4pm) for one day. After which they will attend the laboratory, 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.

Control

Participants will undertake an acute standard western feeding pattern (feeding between 8am-8pm).

Group Type EXPERIMENTAL

Control

Intervention Type BEHAVIORAL

Participants will undertake an acute standard western feeding pattern (feeding between 8am-8pm). After which, participants will visit the laboratory the following day, after 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.

Morning Fasting

Participants will undertake an acute morning fasting trial (feeding between 12pm-8pm).

Group Type EXPERIMENTAL

Morning Fasting

Intervention Type BEHAVIORAL

Participants will undertake an acute morning fasting trial (feeding between 12pm-8pm). After which, participants will visit the laboratory the following day, after 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.
