Portion sizes are the key to losing and maintaining your weight. Nowadays portion sizes have increased significantly, especially in restaurants and with processed, pre-packaged foods which aim to give you more food for your dollar. Learning about what an actual portion size looks like, as well as learning to read a food label, can be helpful in discerning the amount of food you should be eating throughout your day. You may consider starting a food diary to keep track of the amount and types of foods you eat each day.
In the beginning, it may be helpful to actually measure out your portions for each meal using measuring cups and spoons, and a small kitchen scale, but there are also common household items that you could use to get an idea of a proper portion (see list below). The “plate model” can also be a useful guide, with the idea that you fill half of your plate with fresh or cooked vegetables or fruit while limiting your proteins and starches to one quarter each. You can even purchase plates that mark off sections for each portion.
For times when you are in a hurry or on the go, pre-portioning foods ahead of time can be helpful. For example, at the beginning of each week, you could make plastic baggies of the appropriate portions of nuts, baby carrots and celery, cheese cubes and crackers, or cereal to use as snacks throughout the week.
Remember to be aware of the amount of condiments and dressings you are using as well, as the calories in these can really add up. Portion sizes for alcohol and other caloric beverages should also be taken into account. The recommended serving of alcohol is 1 drink per day for women and 2 drinks per day for men. One drink is equal to 5 oz. of wine, 12 oz. of beer or 1.5 oz. of distilled alcohol. Each of these provides about 100 calories or more so watch your intake when watching your weight. Mixed drinks typically provide even more calories per serving.
Once you have a good idea of what an appropriate portion size is for different types of foods, you will find it easier to estimate your portions when eating out. Generally restaurants serve at least double the amount of an appropriate portion, so divide your entrée in half and take home the rest, share with a friend, or go with an appetizer portion instead. When purchasing food or drinks with a food label, it is always important to first look at the serving size. More often than not, there is more than one serving in the product.
At first you may be surprised by how small a portion really is. But do not worry; you can eat multiple portions of each food group throughout the day. Focus on eating slowly and enjoying each bite of food. When having dinner, make your plate and put the rest away immediately so you won’t be tempted to have seconds. Serving your meals on smaller plates is a visual trick that will help you get used to the appropriate portion sizes.
The Food Guide Pyramid (http://www.mypyramid.gov/) can help you figure out the daily number of servings of each food group you should be eating for a balanced diet.Here are examples of appropriate portion sizes for each group:

- 1 slice of bread, ½ English muffin, 6” inch tortilla
- 1 cup of cereal
Vegetables
