Eat sweets at the end of the meal, instead of on their own as a snack

Having dessert after a balanced meal allows you to get the benefit of the nutrients in the meal to stabilize your blood sugar from the sweets. When dessert is 'attached' to a meal, it signals doneness, so it's less likely to trigger a bunch of mindless snacking. On the other hand, eating sweets as a snack on an empty stomach should be avoided since the body will absorb it faster and lead to a bigger blood sugar spike-and a bigger crash hours later.
