Study Arms:
- UK dietary guideline diet (Type: EXPERIMENTAL): A 4-day diet (food and beverage provision for 3 meals and 2 snacks) will be provided along with an eating plan (time of each meal / snack). The experimental diet will meet UK dietary guidelines for fiber, salt, sugar, saturated fat, fruit and vegetable intake. Energy (calorie) requirements for each participant will be calculated from age, sex and weight of the participant. The diet will be consumed across 3 consecutive night shifts.
- Shift worker diet (Type: OTHER): A 4-day diet (food and beverage provision for 3 meals and 2 snacks) will be provided along with an eating plan (time of each meal / snack). Typical 'shift diet' based on previous research investigating what UK night workers eat. The 'shift diet' will contain \~15% energy from added sugar, 15g fiber, 2.5 portions fruit/vegetable, no whole grains. Required energy intake (calories) for each day to maintain their current body weight. Energy (calorie) requirements for each participant will be calculated from age, sex and weight of the participant.The diet will be consumed across 3 consecutive night shifts.
