Invisalign diet is one of the most effective weight loss diet out there. While there is no diet restriction during Invisalign treatment, the invisible aligners need to be taken off before a meal. Proper brushing and flossing is required before you put your aligners back in. For people who have a snacking habit, it deters them from munching a handful of m&m’s throughout the day. Although there is no research data out there suggesting that Invisalign promotes weight loss, just imagine the hassle having to brush and floss every time you snack on something. Most people give up their snacking habit because it simply doesn’t worth the trouble.
