Although it is known that obesity is an issue of energy balance, the components of energy expenditure seem to be inter-related in complex non-additive ways. The aim of this study is to explore the downstream impacts of exercise on short term changes in both expenditure and energy intake. The primary question the investigators are asking is whether moderate to high intensity exercise influences the basal energy expenditure and\u002For energy intake\u002Fmacronutrient preference in young adult males? (A similar study will be performed on females in a different registration). The investigators will use a specially designed feeding table to measure energy intake and macronutrient intake, which is easy to quantify intake compensation. Basal metabolism will be measured by hood indirect calorimetry. The investigators will explore the factors that influence the level of compensation in expenditure and intake, in particular body composition. Participants will be asked to come to the lab after 10 hours fast for body composition tests including Dual Energy X-ray Absorptiometry(DXA), Magnetic Resonance Image(MRI) and Bioelectrical Impedance Analysis(BIA). They will then be asked (not) to do 30 minutes of moderate-to-vigorous exercise after an energy-limiting breakfast, during which metabolic rate levels and changes in dietary composition will be recorded by gas exchange and standardized buffet. In addition, participants' subjective hunger and preferences will also be recorded by questionnaires. Venous blood will be collected to measure metabolic and hormone factors, blood glucose will be measured by Continuous Blood Glucose Monitor (CGM).",[62,63,29,64],"Energy Expenditure","Exercise","Food Preferences",[66,67,64],"Energy compensation","Energy balance","RECRUITING","2025-08-11",{"date":71,"type":40},"2025-08-15",{"date":73,"type":40},"2024-05-20",{"date":75,"type":22},"2025-12-30",{"name":77,"class":47},"Shenzhen Institutes of Advanced Technology ,Chinese Academy of Sciences",1,{"id":80,"slug":81,"hasResults":11,"nctId":82,"briefTitle":83,"officialTitle":84,"acronym":4,"eligibilityCriteria":85,"healthyVolunteers":16,"sex":86,"minAge":18,"maxAge":87,"enrollmentInfo":88,"targetDuration":4,"studyType":23,"phases":90,"briefSummary":91,"conditions":92,"keywords":94,"overallStatus":68,"whyStopped":4,"lastUpdateSubmitDate":99,"lastUpdatePostDateStruct":100,"startDateStruct":102,"completionDateStruct":104,"leadSponsor":106,"locationsCount":78},"100590361","effects-of-different-timing-of-bodyweight-high-intensity-exercise-on-human-behaviours-100590361","NCT06966414","Effects of Different Timing of Bodyweight High-intensity Exercise on Human Behaviours","Effects of Bodyweight High-intensity Exercise at Different Times of Day on 72-hour Eating Behaviours and Physical Activity in Physically Inactive Adults","Inclusion Criteria:\n\n* Aged between 20 and 50 years, with a BMI ranging from 19 to 27 kg\u002Fm².\n* Classified as having \"low\" physical activity levels (750 Metabolic Equivalents \u002F week) according to the International Physical Activity Questionnaire (IPAQ).\n* Engaged in moderate-intensity exercise for no more than 3 days per week and less than 30 minutes per session in the 3 months preceding the study.\n* Maintained a stable body weight (± 3 kg) during the 3 months prior to the main experiment.\n* Not taking any medications, supplements, or vitamins that might affect food intake, appetite, physical activity, weight loss, or metabolism.\n* Free from cardiovascular and metabolic diseases.\n* Not pregnant or planning to become pregnant.\n* Not currently on a diet or undergoing any specific dietary interventions (e.g., intermittent fasting, ketogenic diet).\n* No injuries or surgical wounds preventing physical activity.\n* Regular sleep patterns, averaging 7-9 hours per night, with no shift work.\n* No habits of heavy alcohol consumption or smoking.\n\nExclusion Criteria:\n\n* Personal history of\u002Fexisting diabetes, cardiovascular disease, metabolic disease or dyslipidaemia.\n* Taking medications that may influence lipid or carbohydrate metabolism or immune system function.\n* Unable to take part in exercise for any reason (e.g., injury or disability) or a positive response to any questions on the Physical Activity Readiness questionnaire (PAR-Q).","ALL","50 Years",{"count":89,"type":22},20,[25],"The purpose of this project is to investigate the effects of exercise at different times of day on 72-hour eating behaviour, physical activity and sedentary behaviour in physically inactive adults.",[28,29,93],"Sedentary Behavior",[95,96,97,98],"Timing of exercise","Morning exercise","Evening exercise","Behavioural compensation","2025-05-07",{"date":101,"type":40},"2025-05-11",{"date":103,"type":40},"2025-04-30",{"date":105,"type":22},"2026-04-24",{"name":46,"class":47},{"id":108,"slug":109,"hasResults":11,"nctId":110,"briefTitle":111,"officialTitle":112,"acronym":4,"eligibilityCriteria":113,"healthyVolunteers":16,"sex":114,"minAge":55,"maxAge":115,"enrollmentInfo":116,"targetDuration":4,"studyType":23,"phases":118,"briefSummary":119,"conditions":120,"keywords":4,"overallStatus":68,"whyStopped":4,"lastUpdateSubmitDate":123,"lastUpdatePostDateStruct":124,"startDateStruct":126,"completionDateStruct":128,"leadSponsor":130,"locationsCount":78},"100586196","hypoxia-appetite-and-energy-intake-in-young-female-adults-100586196","NCT06912230","Hypoxia, Appetite, and Energy Intake in Young Female Adults","Appetite and Energy Intake in Young Female Adults During and After Simulated High-Altitude","Inclusion Criteria:\n\n* English or French speaking\n* Ability to provide informed consent\n\nExclusion Criteria:\n\n* History or evidence of chronic disease\n* Current use of hypolipemic medication\n* Current use of hormonal contraceptives\n* Current use of antidepressants\n* Current use of anticoagulants\n* Ongoing smoking status\n* Experiencing pregnancy, puerperium, or irregular menstrual cycles","FEMALE","30 Years",{"count":117,"type":22},10,[25],"The goal of this clinical trial is to investigate the effects of acute passive continuous hypoxemia (simulated high-altitude at rest) on appetite and energy intake in healthy young female adults.

Traditional methods, like food diaries, rely on self-reporting of individuals, and suffer from poor accuracy and recall bias.\n\nAims: This project aims to identify physiological biomarkers related to food and energy intake, which may be used to develop an objective tool to estimate individuals' food intake in future. Eating behaviours are accompanied by significant physiological changes such as skin temperature, blood oxygen saturation, pulse rate etc. The investigators intend to investigate whether monitoring these physiological changes can help us estimate eating behaviour, such as meal size, eating speed, and duration of meals.\n\nStudy design: Ten healthy adults will be invited for two study visits at NIHR Imperial Clinical Research Facility. Each visit will last for approximately 2 hr. They will consume a high- and low-calorie meal designed by nutritional researchers in a randomised order. During eating events, the investigators will track their physiological changes via a bedside monitor and wearable sensors. Blood samples will be taken from participants to measure their glycaemic response. Associations between energy load, glycaemic response, and physiological changes will be investigated.
