Despite the glut of modern-day innovations to aid weight loss, from “toning” sandals to iPhone apps, it still boils down to calories in versus calories out, or burned. But studies show dramatic calorie restriction isn’t realistic for achieving and sustaining a healthy weight. Instead, make small, doable choices that favor good nutrition over empty calories. “If you cut just 100 calories a day with some smart food swaps, you could trim off 10 pounds in a year—and improve the nutritional quality of your diet,” says Lisa R. Young, RD, PhD, author of The Portion Teller Plan (Crown Archetype, 2005).
Try these simple tricks.
Old habit: Eating cereal for breakfast
New trick: Add a hard-boiled egg
People who ate eggs for breakfast took in about 400 fewer calories over a 24-hour period than did those who consumed a carbohydrate-rich breakfast with the same number of calories, in a 2010 University of Connecticut study. The carb eaters also had much higher blood levels of ghrelin, a hunger-stimulating hormone. Nutritionally, eggs offer vitamins A, B12, and D; selenium; and lutein, an antioxidant thought to protect eye health. Other good proteins to add, says Young: yogurt, nut butters, and smoked salmon. And remember, when choosing cereals, aim for at least 3 grams of fiber per serving.
Old habit: Slathering mayonnaise on sandwiches
New trick: Switch to whole-grain mustard
A tablespoon of most light or regular mayo brands contains 50–100 calories, respectively; the same amount of mustard has about 10. Bonus: Mustard seeds are a good source of antioxidant selenium, which may safeguard against skin cancer.
Old habit: Marinating meats in oil-based sauces
New trick: Try spice rubs Calorie-free spice and herb rubs pump up meats’ flavor and cut out about 100 oily marinade calories. “Turmeric, cayenne, and oregano all pack a serious antioxidant wallop,” says Young. And capsaicin, a phytochemical in chili powder and cayenne, can reduce hunger and calorie intake at a meal, studies suggest. Alter traditional marinade recipes to include less oil and more low-calorie vinegar, citrus, and other fruit juices, which may also reduce char-based carcinogens in well-done grilled meats.
Old habit: Baking muffins with butter or oil
New trick: Use mostly fruit or vegetable purées instead
If your recipe calls for 1 cup butter, you’re adding more than 1,600 calories and lots of saturated fat. Try swapping naturally rich, sweet purées (applesauce, pumpkin, banana, or sweet potato) for half or two-thirds of the total called-for fats and sweeteners. “Not only does this reduce baked-goods’ calorie density but you get an extra dose of antioxidants and filling fiber,” says Barbara Rolls, PhD, nutrition professor at Penn State University and author of The Volumetrics Eating Plan (HarperCollins, 2007). Plus, you’ll end up eating more nutrient-rich fruits and vegetables.
Old habit: Using sour cream for dips, baked potatoes, and enchiladas
New trick: Substitute reduced-fat Greek yogurt
Plain, reduced-fat Greek yogurt is just as rich and velvety as full-fat sour cream, but has a third fewer calories and eight times less saturated fat. “You also get twice as much protein to help reduce hunger and plenty of gut-friendly bacteria that may improve digestion and immunity,” says Young. Greek yogurt can also stand in for mayonnaise in tuna, egg, and potato salads.
