Summary

This study aims to explore how early time-restricted eating (eTRE) - where all daily meals are eaten within a specific time window - affects health and quality of life in adults. The researchers will compare results between adults with mild, well-controlled asthma and adults without asthma (the control group). Participants can continue to eat their normal food; only the timing of meals will change.

Detailed description

During the study, participants will be asked to: * Follow an early time-restricted eating schedule for one week and their usual eating schedule for another week while keeping to their usual diet and physical activity. * Attend four visits to the research facility on campus. * Provide saliva, blood, and urine samples for health marker analysis. * Complete breathing tests (spirometry and FeNO) to measure lung function. * Complete short questionnaires about physical activity and quality of life. * Take part in a short interview about their asthma symptoms and quality of life. * Keep a brief food diary each week. * Provide details of any medications they currently take.
