Oatmeal Fibre-rich oatmeal is a great option for breakfast because it's filling, so you won't indulge in a muffin or bagel by midmorning. It's also full of fibre, which can help regulate your digestion. Opt for plain oatmeal since the flavoured brands can be full of sugar; jazz it up yourself with fresh berries and nuts. Try it: Make this delicious oatmeal twist that uses coconut water or this chocolate peanut butter oatmeal that will satisfy your sweet tooth. Image Source: POPSUGAR Photography / Benjamin Stone
