Eat Smaller Meals More Often
"Instead of three big meals per day, try eating smaller meals more often. This can keep you free of the bloated feeling that often follows large meals (think Thanksgiving). Eating more frequently can also help control blood sugar and manage hunger.
So go for five to six small meals each day, but make sure the quantity of food and calories are proportionate to your needs. To create a daily meal plan that includes the recommended amounts of all major nutrients, visit the U.S. Department of Agriculture's MyPlate web site."
This is a super helpful tip for wanting to keep a flat tummy!
I've done this for as long as I can remember.
