Portion control is essential for taking off weight and keeping it off. Even healthy foods like nuts and whole grains when eaten in mass quantities will pack on the pounds, so make sure to measure your food every day. Doing a little meal prep like making a week's worth of overnight oats is one way to ensure you stick to a healthy portion size. When eating dinner at home, serve yourself an appropriate-size portion and then put away the rest so you won't be tempted to go back for seconds. And don't feel compelled to be a member of the clean-plate club. Eat slowly and listen to your body — if you're full after eating two-thirds of your meal, put the rest away for tomorrow's lunch.
