About This Quiz

There is a lot of dieting misinformation out there, but this quiz, formulated with facts from the National Institute of Health, could help you take weight off and keep it off.

Skipping meals is a good way to lose weight.

Your body needs a certain amount of calories and nutrients each day in order to work properly. If you skip meals during the day, you will more likely make up for the missing calories by snacking or eating more at the next meal.


Eating after 8 p.m. causes weight gain.

It doesn't matter what time of the day you eat, it's how much you eat during the whole day and how much exercise you get that make you gain or lose weight.


Certain foods, like grapefruit, celery or cabbage soup, can burn fat and make you lose weight.

No food 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.


Nuts are fattening and you shouldn't eat them if you want to lose weight.

Although high in calories and fat, most (but not all) types of nuts have low amounts of saturated fat. Saturated fat is the kind of fat that can lead to high blood cholesterol levels and increase the risk of heart disease.


Becoming a vegetarian means you are sure to lose weight and be healthier.

Vegetarian diets can be healthy because they are often lower in saturated fat and cholesterol and higher in fiber. Choosing a vegetarian diet with low-fat content can be helpful for weight loss. But vegetarians -- like non-vegetarians -- can also make poor food choices, like eating large amounts of junk (nutritionally-empty) foods.


Fresh fruits and vegetables are more nutritious than frozen or canned.

Most fruits and vegetables (produce) are naturally low in fat and calories. Frozen and canned fruits and vegetables can be just as nutritious as fresh.


Starches are fattening and should be limited when trying to lose weight.

Potatoes, rice, pasta, bread, beans and some vegetables (like squash, yams, sweet potatoes, turnips, beets and carrots) are rich in complex carbohydrates (also called starch). Starch is an important source of energy for your body. Foods high in starch become high in fat and calories when you eat them with large amounts of sauces, cheeses and other high-fat toppings.
