Super Slimming Foods
Oats are another terrific source of metabolism-boosting resistant starch, with 4.6 grams in a half-cup serving. And they’re particularly good for your waistline when cooked: in a recent Nutrition Journal study, participants who ate 220 calories of hot oatmeal for breakfast reported less hunger later in the day than those who ate cold oat cereal.
Like lemons, oranges are low in calories but contain plenty of fiber, helping you to feel full throughout the day and consume less overall. In fact, in a list of the most filling foods compiled by Australian researchers, oranges ranked the highest among fruits.
From January to April, keep your eyes peeled for blood oranges, a darker-hued winter variety of the citrus that contains a full day’s worth of vitamin C as well as high levels of the disease-fighting antioxidant anthocyanin.
Your favorite childhood snack is good for your grown-up self, too. Because peanut butter is a great source of protein and healthy fats, it can curb hunger and keep you feeling full long after you’re finished eating. Having small snacks during the day that include a lean protein such as peanut butter with complex carbs (like an apple or banana) can also help keep your metabolism running smoothly.
Another reason to indulge: Research suggests that eating peanut butter as part of a healthy diet could benefit your heart and maybe even lengthen your life. Just be sure to carefully read the nutrition labels on the jar and choose a brand that doesn’t have any added sugar and contains only peanuts and salt.
Pearl barley is a type of barley that has been polished to remove the hull and outer bran layer, which helps it cook more quickly. Another great source of fiber and slimming resistant starch (nearly 2 grams per half-cup serving), pearl barley helps increase feelings of satiety.
