Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Net whole-body protein synthesis | 0, 2, 5, 10, 15, 20, 30, 40, 50, 60, 90, 120, 150, 180, 210, 225, 240, 260, 280, 300, 320, 340, 360 ± 5 min | Change in whole-body protein synthesis rate after intake of meal |
| Secondary | Group differences in state of mood as measured by the Hospital Anxiety and Depression Scale (HADS), | Postabsorptive state during 3 hours and change after feeding on study day 1 and the change from day 2 and day 3 (obese only) | a fourteen item self-assessment scale. Seven of the items related to anxiety and seven relate to depression. Each item on the questionnaire is scored from 0-3 and this means that a person can score between 0 (no symptoms) and 21 (severe symptoms) for either anxiety or depression. |
| Secondary | Executive Function-Adolescent/Adult Sensory Profile (ASP): | Postabsorptive state during 3 hours and change after feeding on study day 1 and the change from day 2 and day 3 (obese only) | a standardized self-questionnaire that generates an individualized profile of sensory processing across four quadrants: low registration, sensation seeking, sensory sensitivity, and sensation avoiding. |
| Secondary | Group differences in quality of life as measured by Short Form (36) Health Survey (SF36) | Postabsorptive state during 3 hours and change after feeding on study day 1 and the change from day 2 and day 3 (obese only) | self administered questionnaire that measures each of the following eight health concepts: Physical Functioning (PF); Role-Physical (RP); Bodily Pain (BP); General Health (GH); Vitality (VT); Social Functioning (SF); Role-Emotional (RE); Mental Health (MH) as well as a reported Health Transition item (HT). |
| Secondary | Group differences in activity as measured by Physical Activity Scale for the Elderly (PASE) | Postabsorptive state during 3 hours and change after feeding on study day 1 and the change from day 2 and day 3 (obese only) | questionnaire is intended for use in an elderly population and focuses on 3 types of activities: leisure time activities, household activities and work-related activities. |
| Secondary | Group differences in attention and executive functions as measured by Stroop Color-Word Test (SCWT), | Postabsorptive state during 3 hours and change after feeding on study day 1 and the change from day 2 and day 3 (obese only) | a word page with words printed in black ink, a color page with blocks printed in color, and a color-word page where the color and the word do not match. The examinee reads the words or names the ink colors as quickly as possible within a time limit. Measures selective attention and inhibitory control. The total time in seconds was reported for each trial. |
| Secondary | Group differences in state of mood as measured by the Profile of Mood State (POMS) | Postabsorptive state during 3 hours and change after feeding on study day 1 and the change from day 2 and day 3 (obese only) | A psychological distress scale to measure mood disturbance in 6 domains - fatigue-inertia, vigor-activity, tension-anxiety, depression-dejection, anger-hostility, and confusion-bewilderment. Healthy populations take 3 to 7 minutes to complete, and others may take up a bit longer. |
| Secondary | Group differences in learning and memory as measured by Controlled Oral Word Association Test (COWAT), | Postabsorptive state during 3 hours and change after feeding on study day 1 and the change from day 2 and day 3 (obese only) | Controlled Oral Word Association Test (COWAT): The examinee is required to say as many words as they can think of in one minute that begin with a given letter of the alphabet. The task contains three trials. Measures phonetic verbal fluency. The raw score (total and mean words recorded across the three trials) was reported. |
| Secondary | Group differences in learning and memory as measured by Auditory Verbal Learning Test (AVLT) | Postabsorptive state during 3 hours and change after feeding on study day 1 and the change from day 2 and day 3 (obese only) | Auditory Verbal Learning Test (AVLT): a verbal episodic memory test that evaluates a wide diversity of functions: short-term auditory-verbal memory, rate of learning, retention and recognition of information. |
| Secondary | Group differences in attention and executive functions as measured by PASAT | Postabsorptive state during 3 hours and change after feeding on study day 1 and the change from day 2 and day 3 (obese only) | a measure of cognitive function that assesses auditory information processing speed and flexibility, as well as calculation ability. |
