Awards & highlights


This trial will see if changing when you eat protein affects how your body uses food for energy, and if it reduces snack cravings.

Who is the study for?
This trial is for adults with a BMI < 25 or between 30-34.5, who are generally healthy and have not had significant weight changes recently. Women of childbearing age must use birth control and have regular cycles. Participants should eat normal amounts of protein and maintain consistent activity levels.Check my eligibility
What is being tested?
The study investigates how the timing of protein intake affects energy metabolism and the desire to snack. It compares two patterns: even distribution of protein throughout the day versus a high-protein breakfast with less at other meals.See study design
What are the potential side effects?
Since this trial involves dietary adjustments rather than medication, side effects may include changes in digestion or appetite but are expected to be minimal.
