Weight Loss & Dieting
On this Page
Experts agree that the best way to reach a healthy weight is
to follow a sensible eating plan and engage in regular physical activity.
Weight-loss programs should encourage healthy behaviors that help you lose
weight and that you can maintain over time. Safe and effective weight-loss
programs should include:
-
Healthy eating plans that reduce calories but do not rule out specific
foods or food groups
-
Regular physical activity and/or exercise instruction
-
Tips on healthy behavior changes that also consider your cultural needs
-
Slow and steady weight loss of about ¾ to 2 pounds per week and not
more than 3 pounds per week (weight loss may be faster at the start of
a program)
-
Medical care if you are planning to lose weight by following a special
formula diet, such as a very-low-calorie diet
-
A plan to keep the weight off after you have lost it

Fact: Fad diets are not the best way to lose weight and keep it off. Fad
diets often promise quick weight loss or tell you to cut certain foods out
of your diet. You may lose weight at first on one of these diets. But diets
that strictly limit calories or food choices are hard to follow. Most people
quickly get tired of them and regain any lost weight.
Fad diets may be unhealthy because they may not provide all of the nutrients
your body needs. Also, losing weight at a very rapid rate (more than 3 pounds
a week after the first couple weeks) may increase your risk for developing
gallstones (clusters of solid material in the gallbladder that can be painful).
Diets that provide less than 800 calories per day also could result in heart
rhythm abnormalities, which can be fatal.
Tip: Research suggests that losing ½ to 2 pounds a week by making healthy
food choices, eating moderate portions, and building physical activity into
your daily life is the best way to lose weight and keep it off. By adopting
healthy eating and physical activity habits, you may also lower your risk
for developing type 2 diabetes, heart disease, and high blood pressure.
Fact: The long-term health effects of a high-protein/low-carbohydrate diet
are unknown. But getting most of your daily calories from high-protein foods
like meat, eggs, and cheese is not a balanced eating plan. You may be eating
too much fat and cholesterol, which may raise heart disease risk. You may
be eating too few fruits, vegetables, and whole grains, which may lead to
constipation due to lack of dietary fiber. Following a high-protein/low-carbohydrate
diet may also make you feel nauseous, tired, and weak.
Eating fewer than 130 grams of carbohydrate a day can lead to the buildup
of ketones (partially broken-down fats) in your blood. A buildup of ketones
in your blood (called ketosis) can cause your 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 may be especially risky for pregnant women
and people with diabetes or kidney disease.
Tip: High-protein/low-carbohydrate diets are often low in calories because
food choices are strictly limited, so they may cause short-term weight loss.
But a reduced-calorie eating plan that includes recommended amounts of carbohydrate,
protein, and fat will also allow you to lose weight. By following a balanced
eating plan, you will not have to stop eating whole classes of foods, such
as whole grains, fruits, and vegetables—and miss the key nutrients
they contain. You may also find it easier to stick with a diet or eating
plan that includes a greater variety of foods.
Fact: Many foods high in starch, like bread, rice, pasta, cereals, beans,
fruits, and some vegetables (like potatoes and yams) are low in fat and calories.
They become high in fat and calories when eaten in large portion sizes or
when covered with high-fat toppings like butter, sour cream, or mayonnaise.
Foods high in starch (also called complex carbohydrates) are an important
source of energy for your body.
Tip: The Dietary Guidelines for Americans recommends eating 6 to 11 servings
a day, depending on your calorie needs, from the bread, cereal, rice, and
pasta group—even when trying to lose weight. Pay attention to your
serving sizes—one serving is equal to 1 slice of bread, 1 ounce of
ready-to-eat cereal, or ½ cup of pasta, rice, or cooked cereal. Try to avoid
high-fat toppings and choose whole grains, like whole wheat bread, brown
rice, oatmeal, and bran cereal. Choose other starchy foods that are high
in dietary fiber too, like beans, peas, and vegetables.
Fact: No foods can burn fat. Some foods with caffeine may speed up your
metabolism (the way your body uses energy, or calories) for a short time,
but they do not cause weight loss.
Tip: The best way to lose weight is to cut back on the number of calories
you eat and be more physically active.
Fact: A weight-loss product that claims to be “natural” or “herbal” is
not necessarily safe. These products are not usually scientifically tested
to prove that they are safe or that they work. For example, herbal products
containing ephedra (now banned by the U.S. Government) have caused serious
health problems and even death. Newer products that claim to be ephedra-free
are not necessarily danger-free, because they may contain ingredients similar
to ephedra.
Tip: Talk with your health care provider before using any weight-loss product.
Some natural or herbal weight-loss products can be harmful.

Fact: To lose weight, you need to use more calories than you eat. It is
possible to eat any kind of food you want and lose weight. You need to limit
the number of calories you eat every day and/or increase your daily physical
activity. Portion control is the key. Try eating smaller amounts of food
and choosing foods that are low in calories.
Tip: When trying to lose weight, you can still eat your favorite foods—as
long as you pay attention to the total number of calories that you eat.
Fact: A low-fat or nonfat food is often lower in calories than the same
size portion of the full-fat product. But many processed low-fat or nonfat
foods have just as many calories as the full-fat version of the same food
or even more calories. They may contain added sugar, flour, or starch thickeners
to improve flavor and texture after fat is removed. These ingredients add
calories.
Fact: Fast foods can be part of a healthy weight-loss program with a little
bit of know-how.
Tip: Avoid supersize combo meals, or split one with a friend. Sip on water
or nonfat milk instead of soda. Choose salads and grilled foods, like a grilled
chicken breast sandwich or small hamburger. Try a “fresco” taco
(with salsa instead of cheese or sauce) at taco stands. Fried foods, like
French fries and fried chicken, are high in fat and calories, so order them
only once in a while, order a small portion, or split an order with a friend.
Also, use only small amounts of high-fat, high-calorie toppings, like regular
mayonnaise, salad dressings, bacon, and cheese.
Fact: Studies show that people who skip breakfast and eat fewer times during
the day tend to be heavier than people who eat a healthy breakfast and eat
four or five times a day. This may be because people who skip meals tend
to feel hungrier later on, and eat more than they normally would. It may
also be that eating many small meals throughout the day helps people control
their appetites.
Fact: It does not matter what time of day you eat. It is what and how much
you eat and how much physical activity you do during the whole day that determines
whether you gain, lose, or maintain your weight. No matter when you eat,
your body will store extra calories as fat.
Tip: If you want to have a snack before bedtime, think first about how many
calories you have eaten that day. And try to avoid snacking in front of the
TV at night it may be easier to overeat when you are distracted by the television.

Fact: Lifting weights or doing strengthening activities like push-ups and
crunches on a regular basis can actually help you maintain or lose weight.
These activities can help you build muscle, and muscle burns more calories
than body fat. So if you have more muscle, you burn more calories—even
sitting still. Doing strengthening activities 2 or 3 days a week will not “bulk
you up.” Only intense strength training, combined with a certain genetic
background, can build very large muscles.
Tip: In addition to doing at least 30 minutes of moderate-intensity physical
activity (like walking 2 miles in 30 minutes) on most days of the week, try
to do strengthening activities 2 to 3 days a week. You can lift weights,
use large rubber bands (resistance bands), do push-ups or sit-ups, or do
household or garden tasks that make you lift or dig.

Fact: In small amounts, nuts can be part of a healthy weight-loss program.
Nuts are high in calories and fat. However, most nuts contain healthy fats
that do not clog arteries. Nuts are also good sources of protein, dietary
fiber, and minerals including magnesium and copper.
Tip: Enjoy small portions of nuts. One-third cup of mixed nuts has about
270 calories.
Fact: Eating lean meat in small amounts can be part of a healthy weight-loss
plan. Red meat, pork, chicken, and fish contain some cholesterol and saturated
fat (the least healthy kind of fat). They also contain healthy nutrients
like protein, iron, and zinc.
Tip: Choose cuts of meat that are lower in fat and trim all visible fat.
Lower fat meats include pork tenderloin and beef round steak, tenderloin,
sirloin tip, flank steak, and extra lean ground beef. Also, pay attention
to portion size. One serving is 2 to 3 ounces of cooked meat—about
the size of a deck of cards.
Fact: Low-fat and nonfat milk, yogurt, and cheese are just as nutritious
as whole milk dairy products, but they are lower in fat and calories. Dairy
products have many nutrients your body needs. They offer protein to build
muscles and help organs work properly, and calcium to strengthen bones. Most
milks and some yogurts are fortified with vitamin D to help your body use
calcium.
Tip: The Dietary Guidelines for Americans recommend that people aged 9 to
18 and over age 50 have three servings of milk, yogurt, and cheese a day.
Adults aged 19 to 49 need two servings a day, even when trying to lose weight.
A serving is equal to 1 cup of milk or yogurt, 1½ ounces of natural cheese
such as cheddar, or 2 ounces of processed cheese such as American. Choose
low-fat or nonfat dairy products including milk, yogurt, cheese, and ice
cream.
If you cannot digest lactose (the sugar found in dairy products), choose
low-lactose or lactose-free dairy products, or other foods and beverages
that offer calcium and vitamin D (listed below).
Fact: Research shows that people who follow a vegetarian eating plan, on
average, eat fewer calories and less fat than non-vegetarians. They also
tend to have lower body weights relative to their heights than non-vegetarians.
Choosing a vegetarian eating plan with a low fat content may be helpful for
weight loss. But vegetarians—like non-vegetarians—can make food
choices that contribute to weight gain, like eating large amounts of high-fat,
high-calorie foods or foods with little or no nutritional value.
Vegetarian diets should be as carefully planned as non-vegetarian diets
to make sure they are balanced. Nutrients that non-vegetarians normally get
from animal products, but that are not always found in a vegetarian eating
plan, are iron, calcium, vitamin D, vitamin B12, zinc, and protein.
Tip: Choose a vegetarian eating plan that is low in fat and that provides
all of the nutrients your body needs. Food and beverage sources of nutrients
that may be lacking in a vegetarian diet are listed below.
-
Iron: cashews, spinach, lentils, garbanzo beans, fortified
bread or cereal
-
Calcium: dairy products, fortified soy-based beverages
or fruit juices, tofu made with calcium sulfate, collard greens, kale,
broccoli
-
Vitamin D: fortified foods and beverages including milk,
soy-based beverages, fruit juices, or cereal
-
Vitamin B12: eggs, dairy products, fortified cereal or
soy-based beverages, tempeh, miso (tempeh and miso are foods made from
soybeans)
-
Zinc: whole grains (especially the germ and bran of the
grain), nuts, tofu, leafy vegetables (spinach, cabbage, lettuce)
-
Protein: eggs, dairy products, beans, peas, nuts, seeds,
tofu, tempeh, soy-based burgers.
