Temporal Eating Patterns and Metabolic Health (TIME-MET)
Obesity and its related health problem, like fatty liver disease and type 2 diabetes, are major health problems worldwide and can lead to serious illness and reduced quality of life. Most advice focuses on eating fewer calories and increasing physical activity, but new research suggests that when we eat may also matter. Late meals can disrupt blood sugar control, how the body processes fat, and hormone balance. However, it is not fully understand how meal timing affects people who may be more at-risk. For example new mothers face disrupted sleep, which can lead to eating later in the day. People with fatty liver disease may have eating patterns that unintentionally worsen their condition.
To explore this, the study will include the following groups;
- First-time mothers in early motherhood, and women who do not have children.
- People with fatty liver disease along with people of similar age, sex, and weight who do not have the condition.
The aim of the study is to compare meal timing habits between these groups. All participants will complete a 3-day diet diary and a questionnaire about eating habits, sleep, lifestyle, and daily routines. Some participants may opt to complete an optional body composition check using a mobile app. A smaller subset of volunteers will take part in additional assessment, including a fasting blood sample, basic measurements (such as height, weight, and waist size), a body scan to measure fat and muscle. They will also wear a small device to track their blood sugar and another to monitor sleep and activity for 14 days. This study will increase the current understanding on how eating patterns and daily routines differ in these groups, and may help improve future advice on healthy lifestyles.

Adults with MASLD
Adults aged 18-80 with a confirmed self-reported diagnosis of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), irrespective of disease stage, enrolled to examine the role of temporal eating patterns and metabolic health.
