For optimal results, you’ll need to wear your clear aligners 22 hours a day. Since you have to take out your aligners to eat, this only leaves you with a total of two hours to eat throughout the day. Having limited time to eat may result in you eating less frequently and in smaller quantities.
If you notice yourself losing an alarming amount of weight, Dr. Sheehan recommends setting aside specific times to eat and consuming nutrient-rich meals or protein shakes during these times.
