Ramadan and Energy Expenditure Study
This trial is active, not recruiting.
|Condition||energy expenditure during ramadan fasting|
|Sponsor||Imperial College London Diabetes Centre|
|Start date||June 2015|
|End date||June 2016|
|Trial size||45 participants|
|Trial identifier||NCT02696421, IREC 022|
Ramadan fasting entails abstinence from eating and drinking between dawn and sunset. During this month major changes in meal times and patterns, sleeping times and activity occur. Starvation is known to lead to a compensatory reduction in energy expenditure. However, the Ramadan fast is not synonymous with starvation as it involves intermittent periods of fasting followed by gorging. People who fast during Ramadan feel less energetic. However, little is known about the effects of this religious practice on energy metabolism. .
The aim of this study is to assess energy dynamics before and/or after and during Ramadan fasting in non-obese participants. Resting metabolic rate (RMR), thermic effect of food (TEF), active energy expenditure (AEE) and total energy expenditure (TEE) in free-living conditions will be measured . Indirect calorimetry will be used to assess RMR and TEF, doubly labeled water will be used to measure TEE and activity monitors will measure physical activity. In addition, body composition analysis will be performed by bio-electrical impedance. Blood sample will be taken to exclude medical factors affecting energy metabolism.
