Outcome Measures

Primary Outcomes (4)

  • Glycaemic control (Baseline)

    A metabolic assessment lasting 3.5 hours will take place following a standardised, laboratory-based meal. The investigators will be taking periodic capillary and venous blood samples to measure post-prandial glucose and insulin, which together comprise 'glycaemic control'.

    3.5 hours following the standardised breakfast meal on day 1.

  • Glycaemic control (Post intervention)

    A metabolic assessment lasting 3.5 hours will take place following a standardised, laboratory-based meal. The investigators will be taking periodic capillary and venous blood samples to measure post-prandial glucose and insulin, which together comprise 'glycaemic control'.

    3.5 hours following the standardised breakfast meal on day 4.

  • Energy Intake (Kilocalories)

    Energy intake will be measured both during lab and outside of the laboratory when the participants are free-living. During lab, energy intake will be measured through ad-libitum feeding buffet where 20 minutes will be permitted to eat as much or as little as they desire, until 'comfortably full and satisfied', followed by post-feeding measurement of the remaining food. Outside of laboratory feeding will also be monitored through food diary's and weighing any investigator issued meals.

    Day 1 to day 4.

  • Energy expenditure

    Energy expenditure will be measured via a chest-worn device (Actiheart) which combines heart rate and accelerometry to gauge calories expended.

    Day 1 to day 4.

Secondary Outcomes (6)

  • Cortisol awakening response

    Five samples will be collected by the participant within the first hour of waking on day 5.

  • Visual Analogue Scale for Subjective Ratings of Appetite

    Every 2 hours between 8am-10pm from day 1 to day 4.

  • Acylated Ghrelin (appetite hormone)

    3.5 hours following the standardised breakfast meal on day 1 and day 4.

  • PYY (appetite hormone)

    3.5 hours following the standardised breakfast meal on day 1 and day 4.

  • Carbohydrate oxidation

    During laboratory visits on day 1 and day 4 [baseline, 60min, 120min, 180min]

  • +1 more secondary outcomes

Study Arms (2)

Extended Evening Fasting

EXPERIMENTAL

Participants will eat between 8am-4pm

Behavioral: Extended Evening Fasting

Control

ACTIVE COMPARATOR

Participants will eat between 8am-8pm

Behavioral: Control

Interventions

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.

Extended Evening Fasting
ControlBEHAVIORAL

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.
