Design outcomes

Primary

Measure	Time frame
Our main outcome measurement is the difference in protein intake (g) during the 2-day ad libitum-phase following the two interventions.	—

Secondary

Measure	Time frame
Our secondary outome measurements are: • The difference in energy intake during the 2-day ad libitum-phase following the two interventions; • The difference in subjective appetite ratings during the low protein diet and the high protein diet; • The difference between the two interventions on different aspects of food liking and wanting measured with an Food Preference Questionnaire; • The difference in systolic blood pressure following the low protein diet and the high protein diet.	—
