Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Does a protein-rich liquid meal result in less satiety and therefore higher ad libitum energy intake at the next meal than an isocaloric oatmeal with the same macronutrient ratio?
* Is the consumption of a protein-rich liquid meal as a beverage in addition to an ad libitum oatmeal less compensated within the meal and at the next meal and provides thus a higher ad libitum energy intake than an isovolumetric noncaloric soft drink in addition to an ad libitum oatmeal?
Researchers will compare a protein-rich liquid meal to an isocaloric oatmeal with matched macronutrient composition to answer the first question. Researchers will compare a protein-rich liquid meal + oatmeal to a noncaloric softdrink (water with sucralose and flavoring) + oatmeal to answer the second question.
Participants will:
* spend 4 intervention days in a metabolic chamber (whole room indirect calorimeter)
* consume pre-definied preloads for breakfast and ad libitum lunch meals on 4 intervention days

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
isocaloric preload
In this arm of the study, participants receive two different isocaloric preloads for breakfast, one as a liquid meal and one as oatmeal.
liquid meal
An isocaloric amount (500 kcal) of a commercially available liquid meal with a matched macronutrient composition is consumed. After 5 hours, lunch is eaten ad libitum.
semi-solid meal
An isocaloric amount (500 kcal) of a commercially available semi-solid oatmeal with a matched macronutrient composition is consumed. After 5 hours, lunch is eaten ad libitum.
ad libitum preload
In this arm of the study, participants are given two different isovolumetric drinks as a preload in addition to an ad libitum oatmeal breakfast. One drink is a liquid meal, the other is a non-caloric soft drink (water, sucralose, flavour).
caloric drink + semi-solid meal
A predefined amount of a caloric drink (= liquid meal) together with an ad libitum amount of a semi-solid meal is consumed. After 5 hours, lunch is eaten ad libitum.
non-caloric drink + semi-solid meal
A predefined amount of a non-caloric drink (= water, sucralose, flavor) together with an ad libitum amount of a semi-solid meal is consumed. After 5 hours, lunch is eaten ad libitum.
