Tips for Eating Out

Tips for Eating Out

• Ask for nutrition information (for example, calories, saturated fat, and sodium) before you order when eating out.
• Choose foods that are steamed, broiled, baked, roasted, poached, or stir-fried, but not deep-fat fried.
• Share food, such as a main dish or dessert, with your dining partner.
• Take part of the food home with you and refrigerate immediately. You may want to ask for a take-home container when the meal arrives. Spoon half the meal into it, so you're more likely to eat only what's left on your plate.
• Request your meal to be served without gravy, sauces, butter or margarine.
• Ask for salad dressing on the side, and use only small amounts of full-fat dressings.

Avoid 'Fad' Diets

Avoid 'Fad' Diets

The cabbage soup diet, the low-carbohydrate and high-protein diet, and other so-called "fad" diets are fundamentally different from federal nutrition dietary guidelines and are not recommended for losing weight.

Fad diets usually overemphasize one particular food or type of food, contradicting the guidelines for good nutrition, which recommend eating a variety of foods from the Food Guide Pyramid. These diets may work at first because they cut calories, but they rarely have a permanent effect.

A high-protein diet is one fad diet that has remained popular over the years. "High-protein items may also be high in fat," says Robert Eckel, M.D., professor of medicine at the University of Colorado Health Sciences Center in Denver. High-fat diets can raise blood cholesterol levels, which increases a person's risk for heart disease and certain cancers.

High-protein diets force the kidneys to try to get rid of the excess waste products of protein and fat, called ketones. A buildup of ketones in the blood (called ketosis) can cause the body to produce high levels of uric acid, which is a risk factor for gout (a painful swelling of the joints) and kidney stones. Ketosis can be especially risky for people with diabetes because it can speed the progression of diabetic renal disease, says Eckel.

"It's important for the public to understand that no scientific evidence supports the claim that high-protein diets enable people to maintain their initial weight loss," says Eckel. "In general, quick weight-loss diets don't work for most people."

Worth the Effort

"Losing weight requires major lifestyle changes, including diet and nutrition, exercise, behavior modification, and--when appropriate--intervention with drug therapy," says Judith S. Stern, Sc.D., professor of nutrition and internal medicine at the University of California, Davis, and vice president of the American Obesity Association. "But it is always worth making the effort to improve your health."

Beware of Unproven Claims

Some dietary supplement makers claim their products work for weight loss. These products are not approved by the FDA before they are marketed. Under existing laws, manufacturers have the responsibility for ensuring that their dietary supplement products are safe and effective.

Many weight-loss products claim to be "natural" or "herbal," but this does not necessarily mean that they're safe. These ingredients may interact with drugs or may be dangerous for people with certain medical conditions. If you are unsure about a product's claims or the safety of any weight-loss product, check with your doctor before using it.

Over-the-Counter Drugs

Until recently, weight-control drugs containing the active ingredient phenylpropanolamine (also used as a nasal decongestant) were available over-the-counter (OTC). However, based on evidence linking this ingredient to an increased risk of bleeding in the brain (hemorrhagic stroke), the FDA asked drug manufacturers to discontinue marketing products containing phenylpropanolamine. In addition, the FDA issued a public health advisory in November 2000, warning consumers to stop using products containing this ingredient.

The FDA is proposing to classify phenylpropanolamine as "not generally recognized as safe" and is proceeding with regulatory actions that will likely remove this ingredient from the market. Although cough-cold products were reformulated using other nasal decongestant ingredients, there is no currently available active ingredient that is generally recognized as safe and effective for use in an OTC weight-control drug product.

Prescription Weight-Loss Drugs

For obese people who have difficulty losing weight through diet and exercise alone, there are a number of FDA-approved prescription drugs that may help. "On average, individuals who use weight-loss drugs lose about 5 percent to 10 percent of their original weight, though some will lose less and some more," says the FDA's Colman.

All of the prescription weight-loss drugs work by suppressing the appetite except for Xenical (orlistat). Approved by the FDA in 1999, Xenical is the first in a new class of anti-obesity drugs known as lipase inhibitors. Lipase is the enzyme that breaks down dietary fat for use by the body. Xenical interferes with lipase function, decreasing dietary fat absorption by 30 percent. Because the undigested fats are not absorbed, fewer calories are available to the body. This may help in controlling weight. The main side effects of Xenical are cramping, diarrhea, flatulence, intestinal discomfort, and leakage of oily stool.

Meridia (sibutramine), approved by the FDA in 1997, increases the levels of certain brain chemicals that help reduce appetite. Because it may increase blood pressure and heart rate, Meridia should not be used by people with uncontrolled high blood pressure, a history of heart disease, congestive heart failure, irregular heartbeat, or stroke. Other common side effects of Meridia include headache, dry mouth, constipation and insomnia.

Other anti-obesity prescription drugs that were approved by the FDA many years ago based on very short-term, limited data include: Bontril (phendimetrazine tartrate), Desoxyn (methamphetamine) and Ionamin and Adipex-P (phentermine). They are "speed"-like drugs that should not be used by people with heart disease, high blood pressure, an overactive thyroid gland, or glaucoma. These drugs are approved only for short-term use, such as a few weeks.

"There is no magic pill for obesity," says David Orloff, M.D., director of the FDA's Division of Metabolic and Endocrine Drug Products. "The best effect you're going to get is with a concerted long-term regimen of diet and exercise. If you choose to take a drug along with this effort, it may provide additional help."

Prescription weight-loss drugs are approved only for those with a BMI of 30 and above, or 27 and above if they have other risk factors, such as high blood pressure or diabetes.

People should contact a doctor before using any kind of drug, including a weight-loss drug.

Increasing Physical Activity

Most health experts recommend a combination of a reduced-calorie diet and increased physical activity for weight loss.

In addition to helping to control weight, physical activity decreases the risk of dying from coronary heart disease and reduces the risk of developing diabetes, hypertension, and certain cancers. Researchers also have found that daily physical activity may help a person lose weight by partially lessening the slow-down in metabolism that occurs during weight loss.

Exercise does not have to be strenuous to be beneficial. And some studies show that short sessions of exercise several times a day are just as effective at burning calories and improving health as one long session.

To lose weight and to maintain a healthy weight after weight loss, many adults will likely need to do more than 30 minutes of moderate to intensive physical activity daily.
