Hard-Boiled Eggs + Sriracha Sauce
To improve thyroid function — the gland manages growth and metabolism — look no further than a low-calorie, low-fat hard-boiled egg, suggests registered dietitian Amy Shapiro. If you like spice, drizzle your snack with sriracha sauce. “It contains capsaicin, a compound found in chile peppers that helps burn calories and fat,” says Karen Ansel, MS, co-author of The Calendar Diet.
Turkey Jerky + Mustard
An ounce of turkey jerky has 10 grams of protein but only about 60 calories, which makes the fat-free snack a good thing to stash in your desk or to eat on the go, says Ansel. Since protein is digested more slowly than fat or carbs, it keeps you feeling full longer. Mustard’s a low-cal, high-flavor topper.
