What the study is about

Effective nutrition strategies for combatting and/or preventing obesity still need to be identified. This has been the case despite the numerous and different approaches that have been taken. Potential targets for combatting/preventing obesity have been identified, but long-term solutions have not emerged. This study uses time restricted feeding to study the role of dietary protein in obesity prevention and/or treatment. The objectives are to determine the role of skeletal muscle mass as a driver of energy-sensing mechanisms and peripheral signals that regulate appetite and energy intake in overweight and obese adults and to determine the effects of protein timing on muscle mass to regulate appetite and energy intake in overweight and obese adults.

Being studied: Whey protein supplement; Ketogenic aid; Control group - time restricted feeding only

Conditions: Overweight; Obesity
