Cookies as big as frisbees. Muffins the size of flower pots. Bowls of pasta so deep, your fork can barely find the bottom. One reason people's waistlines have expanded over the past few decades is because food portions have too.
People today eat way more than they used to — and way more than they need to. This means that they're constantly taking in more calories than their bodies can burn. Unfortunately, lots of us don't realize that we're eating too much because we've become so used to seeing (and eating!) large portions.
Portion sizes began to increase in the 1980s and have been ballooning ever since. Take bagels, for example: 20 years ago, the average bagel had a 3-inch diameter and 140 calories. Today, bagels often have a 6-inch diameter and 350 calories. One bagel that size actually contains half a person's recommended number of grain servings for an entire day!
The price of such overabundance is high. It's common knowledge that people who consistently overeat are likely to become overweight. But they also risk getting a number of medical problems, including high blood pressure, high cholesterol, type 2 diabetes, bone and joint problems, breathing and sleeping problems, and even depression. Later in life, people who overeat are at greater risk for heart disease, heart failure, and stroke.
It's easy to understand why the food industry tends to serve way more food than is necessary: Customers love to feel like they're getting the best value for their money! But the value meal is no deal when it triples our calories and sets the stage for health problems.
So what can you do to take back control? A good place to start is knowing about two things that can help you eat smart: serving sizes and recommended amounts of different foods.
Look at the label on any product package and you'll see a nutrition information section that gives a serving size for that food. Contrary to popular belief, this serving size is not telling you the amount you should be eating. It's simply a guide to help you see how many calories and nutrients — as well as how much fat, sugar, and salt — you get from eating a specific quantity of that food.
Sometimes the serving size on a package will be a lot less than you are used to eating. In some cases, like vegetables, it's perfectly OK (and even a good idea) to eat more than the serving size listed on the package.
But when it comes to foods that are high in calories, sugar, or fat, the serving size can alert you that you may be getting more than is healthy. Let's say you buy a 20-ounce bottle of soda and drink the whole thing at once. If the label shows the serving size is 8 ounces, not only did you have 2½ servings, you also had 2½ times the listed calories as well as 2½ times the sugar.
Serving sizes tell you how much nutrition you're getting from a particular food. They don't tell you which foods you need to stay healthy, though. That's where the U.S. Department of Agriculture's MyPlate comes in.
MyPlate is divided into four sections with dairy on the side to represent the five food groups:
There's a website, ChooseMyPlate.gov, that offers guidelines to help people figure out how much of these foods they should eat based on age, gender, and activity level. [Please note: By clicking on this link, you will be leaving our site.]
Once we know the types of foods and quantities we should be eating, it's easier to figure out how much of that heaping plate of food our bodies actually need as opposed to how much they want. Instead of going along with what your school cafeteria or favorite restaurant puts on your plate, you can take control by eating only the amount you need.
Serving sizes on food labels and recommended amounts on the ChooseMyPlate site are usually given in grams, ounces, or cups. Of course, most of us don't carry around food scales and measuring cups. So how can we translate those amounts into quantities we can relate to? That's where the following visual cues come in. (Just be warned: Some might seem small, especially to recovering super-sizers!)
One easy way to size up portions if you don't have any measurements is to use your hand as a guide:
Another great way to visualize appropriate portions is to use the concept of the "divided plate." Think of your plate as divided into four equal sections. Use one of the top quarters for protein. Use the other top quarter for starch, preferably a whole grain. Then fill the bottom half with veggies (or a combination of vegetables and fruit). None of the foods should overlap — or be piled high! Not only will dividing your plate like this help you keep portions under control, it can also help you to balance your meals.
Being aware of realistic portion sizes and using the "divided plate" concept can help you avoid overeating. But sometimes these visual cues can be hard — especially when foods are difficult to measure, like a sandwich. It can also be hard to estimate foods like chips and cookies that you might eat right out of the bag.
More tips for portion control:
Most important, make it a habit to let your stomach rather than your eyes tell you when you're done with a meal. The key to maintaining a healthy weight is to listen to your body's natural signals about when it's hungry and when it's full. Sometimes these signals can be confused by constant overeating or constant dieting, which is why it pays to watch portion sizes and make smart food choices.
