Table 5 Types of text messages

• Tips (i.e. Going grocery shopping today? Don’t go if you’re hungry!)

• Reminders (i.e. Read the flyer about the Dutch food guide again. What’s your focus this week?)

• Educational facts (i.e. Did you know that cleaning the house is also a moment of exercise? You can burn up to 140 calories in an hour!)

• Motivational messages (i.e. Are you not completely satisfied with your diet today? Tomorrow is new day, don’t give up!)

• Knowledge based (i.e. Do you know the second step in writing a thought record?)
