In June 2015 the first version of the integrated SPLENDID system (chewing sensor, Mandometer and activity meter) was tested at Wageningen University (the Netherlands). In total, 22 young overweight adults (i.e. 19 females and 3 males) participated. Average age was 22.9 years old and mean BMI 28.0 kg/m2. During two days the participants were told to perform daily-life activities, while their eating- and physical activity behavior was monitored by the SPLENDID system. They started at 11.00 by answer a questionnaire and after that they started to wear the SPLENDID sensors and had lunch. During the afternoon the participants had to perform four physical activities and eat three snacks and drinks at set times. For the physical activities the participants would choose from ten activities, which ranged from walk to vacuum clean and play ball to sit down inside. The snacks consisted of a variety of fruit, cookies and candy. At the end of the afternoon the participants had dinner. On both days they had a main dish consisting of a potato-, vegetable- and meat-component, and a dessert. Finally the participants took of the SPLENDID system and answer a final questionnaire. Furthermore, throughout the test the participants recorded their food consumption and physical activities in diaries. The collected data is now analyzed at the Aristotle University of Thessaloniki (Greece).
