 +===== Findings ===== 
 +  
 +Most participants were satisfied with the self-tracking devices, although the usage of the devices declined over time. Usage of the weight scale stabilized after 3 months of self-tracking.\\  
 +The Pulse activity tracker gave some technical problems, like a short battery life, and was therefore replaced until 6 months after the start of the study in at least 30 participants. Thereafter, no replacement was possible due to a restricted availability of the tracker.\\  
 +About 40% of the participants indicated to have changed their eating habits, and 60% indicated to have increased their physical activity behavior.\\  
 +On average, the participants lost 2 kg after 4 months, which was remained after 12 months. An increase in self-regulation capabilities (goal-orientation after 4 months and decision-making after 12 months) explained this weight loss, next to intention to change weight and self-weighing frequency.\\
