• The initial health and lifestyle survey will take up to ~40 minutes. 
  • Each of the diet and activity surveys asking you to report what you ate/drank and your activities for the previous day will take 20-40 minutes.  The time it takes will depend on how many things you have to report.  The surveys will likely get easier to complete after the first one, as you get more familiar with the survey tools. 
  • The final set of diet and activity surveys that ask you about what you usually eat and drink and your activities over the past year will each take 45-60 minutes to complete – this is because the surveys are trying to capture a much longer timeframe, but will help fill important gaps in information that the past-day surveys might’ve missed.
