Meeting your calorie target


How can you meet your daily calorie target? One approach — probably the most accurate — is to add up the number of calories per serving of all the foods that you eat, and then plan your menus accordingly. You can buy books that list calories per serving for many foods. In addition, the nutrition labels on all packaged foods and beverages provide calories per serving information. Make a point of reading the labels of the foods and drinks you use, noting the number of calories and the serving sizes. Many recipes published in cookbooks, newspapers, and magazines provide similar information.

If you hate counting calories, a different approach is to restrict how much and how often you eat, and to eat meals that are low in calories. Indeed, dietary guidelines issued by the American Heart Association stress common sense in choosing your foods rather than focusing strictly on numbers, such as total calories or calories from fat. Whichever method you choose, research shows that a regular eating schedule — with meals and snacks planned for certain times each day — makes for the most successful approach. The same applies after you have lost weight and want to keep it off. Sticking with an eating schedule increases your chance of maintaining your new weight.

What determines your metabolic rate?

Total metabolism is the rate at which you use energy (measured in calories) when you're exercising or doing anything else (including sleeping). Resting energy expenditure is the rate at which you burn calories when you are not being physically active. Resting energy expenditure varies from person to person and is affected by your age, sex, genetic makeup, psychological state, and level of physical activity. For example, pregnancy and illness both tend to increase resting energy usage. Both total metabolism and resting energy expenditure influence your weight by affecting how many calories you burn in the course of a day.

Some people focus on reducing the fat in their eating plan because, at 9 calories per gram, fat by weight contains more than twice as many calories as carbohydrates or proteins (4 calories per gram). By substituting lean cuts of meat for fatty ones, avoiding high-fat packaged foods and snacks, and refraining from fat-rich products such as butter, mayonnaise, and salad dressings, you can cut out dozens or even hundreds of calories per day. On the other hand, many people mistakenly think that cutting fat always means cutting calories. Some fat-free foods actually contain more calories than the regular versions because manufacturers use extra sugar to make up for the flavor lost in removing the fat. Moreover, low-fat or nonfat foods are not low-calorie if you consume them in large quantities.

Here are some guidelines to follow when straight calorie counting is impractical.

  • Eat foods that are filling and low in calories. That means meals and snacks made with whole grains, such as brown rice, whole-wheat bread, and oatmeal, as well as legumes, such as lentils and other beans.

  • When you eat meat, cut out fat and cut down portion sizes. Choose lean cuts of meat and modest amounts — about 3½ or 4 ounces per serving.

  • Avoid fried foods. Frying foods adds fat and calories. For stovetop cooking, it's better either to stir-fry foods in nonstick pans lightly coated with a cooking-oil spray or to braise them in broth or wine. Baking, broiling, and roasting add no extra fat to your meals.

  • Use low-fat or nonfat dairy foods. Milk, yogurt, and cheese are good sources of protein and calcium, but the whole-milk versions of these dairy products are very high in fat.

  • Avoid fast foods. Hamburgers, chicken nuggets, French fries, and other fast-food meals and snacks tend to promote weight gain for two reasons. First, they are high in fat, calories, or both. Second, the "value meals" are often excessively large and tempt you to overeat.

  • Avoid high-fat and high-carbohydrate snacks. Both types of snacks are high in calories. Even snacks labeled "low-fat" are often high in calories because they contain large amounts of sugars and other carbohydrates.

  • Watch what you drink. Regular sodas, fruit juices, and, especially, alcoholic beverages are high in calories (see "Calories from drinks").

  • Eat scheduled meals and snacks. It may seem that skipping meals or cutting out snacks is a smart way to cut out calories, but doing either of these things can work against you. You need to eat regularly, even when you're on a diet. If you don't, you'll feel so hungry that you may give up in frustration.

One weight-loss method

If you are moderately overweight but not obese, here's one way to tip the energy balance in your favor.

If you are moderately active:

  1. Multiply your weight by 15 to get the number of calories that you need each day to maintain your weight. For example, if you weigh 200 pounds, 200 × 15 = 3,000 weight-maintenance calories.

  2. To lose 1 pound each week, you have to consume 500 fewer calories a day. Thus, for the above example, 3,000 – 500 = 2,500 calories per day.

If you are sedentary:

  1. Follow the steps above, plus

  2. Get 30 minutes of moderate to vigorous activity on most days. Activity of this intensity and duration will burn 150–250 calories a day.
