Help us train a new privacy conscious wearable device called HabitSense! With your help, we can work together to advance health research for those affected by health-damaging lifestyle habits! Interested participants will visit our lab, take home and wear our device, keep a daily food and drink log and participate in short calls with a dietitian. Participants are expected to be available for seven weeks and wear the device for four full alternating weeks. Who can participate? Individuals aged 18 and above Individuals with a BMI of 18.5 and above (our survey tool will calculate this for you) Individuals who live in the Chicago metropolitan area Individuals who can speak, read, and write in English Individuals who own a smartphone and have access to a computer in the home We cannot promise any benefits to you or others from your taking part in this research. Participation is voluntary. Participants are paid up to $370 for following all study procedures. Participants may conclude their involvement in the study at any point in time without penalty and will be paid a prorated amount for their participation.
