From my own experience eating 6 meals a day, makes you more hungry and crave more food and its harder to maintain.
Try 3-4 meals.
Snacking on nuts at night if you need to, to tide you over till the morning

Eat bigger but less meals.
Do not think about eating healthier snacks, but trying to quit snacking in between meals would be a better solution.
Otherwise nuts or berries are nice
