Inclusion criteria

Inclusion criteria: -20-45 years -Written declaration of consent -Men -Non-smoker -No chronic drug treatment -BMI 25-30 kg/m2

Exclusion criteria

Exclusion criteria: - Female subjects, due to the effect of cycle-related fluctuations on satiety hormones - Smoker - Current participation in another intervention study - Diseases affecting nutrient absorption, digestive function, metabolism or excretion - Acute infectious diseases - Chronic illnesses according to medical history (e.g. hepatitis B and C, diabetes mellitus) - Gastrointestinal complaints - History of diverticulosis, constipation - Intolerance or allergy to any component of the intervention

Design outcomes

Primary

MeasureTime frame
Determination of the subjects' subjective feeling of hunger before and after administration of the hydrolysates in each intervention arm by using visual analogue scales.

Secondary

MeasureTime frame
- Determination of the subjects' energy intake with a subsequent ad libitum breakfast by using optiDiet in each intervention arm - Examination of gastric emptying with the aid of a 13C-Na-acetate breath test in each intervention arm - Determination of blood plasma concentrations of the hormones ghrelin, serotonin, GLP 1, CCK, insulin, and plasma glucose in each intervention arm - Sensory test to determine the individual bitter threshold value by using questionnaires
