Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Resting Metabolic Rate | up to 5 hours | Metabolic cart measurement difference before and after intervention |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Satiety by Visual Analog Scale (hunger, fullness, prospective food intake and satisfaction) | Baseline to 4 hours | Difference in area under the curve from baseline of the Mean Visual Analog. Each question on the scale ranges from 0 to 100 mm. The two ends of the scale are anchored by the highest and lowest values (e.g. the hungriest I have ever been to no hunger at all). Some questions have high values on the right and others have high values on the left. Each question (hunger, fullness, prospective food intake and satisfaction) is a sub-scale. Each sub-scale is scored separately. |
| Food Intake | 1 hour after intervention | Meal with unlimited portions |
