Portion Sizes For Weight Loss

Eating the right portion sizes is important for weight loss.  Understanding the proper portions is a learning process and can be challenging at first.

People tend to eat all of what is served to them on their plates. Because of this mindset, it's important to only fill your plate with the proper portions of the various food groups.

With some small changes in the way you eat and think of as “food portions” can get you eating healthier and losing weight.



Making Changes

While it's near impossible to measure every morsel that passes your lips, you can make changes to ensure you are eating healthier with the proper portion sizes.

Start by measuring your foods and beverages when you can until you get a feel for the right portions. It is a super-sized world out there, and most people are surprised to find that their idea of a single serving is actually two or even three. So measuring when you can is critical to changing your mindset of what is the correct amount for each food group.

If you are into bells and whistles, there are food scales that are pre-programmed with nutritional information, as well as scales that will keep a running total of your daily food and nutrient intake for you. However, the only tools you really need are a simple and inexpensive food scale, dry and liquid measuring cups, and learning how to read food labels.

Understanding Portion Sizes

We often relate a serving size to the amount of a particular food that is put on our plates like at restaurants. Unfortunately this gives us a distorted view of what true portion sizes are for that food item.

Portions served to us are in most cases more than a true serving size.  This makes food portion control more difficult. We also do not often measure our foods even when at home and “guess” at what a ½ cup is or 1 serving of a food item.  This again is usually a misleading view of a true portion size if you have never had some visual to measure against.

Unless you have some method to visualize your portions or take the time to physically measure all your food items, then you are risking eating more than the true portion size and will be consuming more calories than you are expecting. 

Measuring is a great way to get a feel for a real serving size and helps you learn food portion control.  However, you can get a general idea of a portion size if you have something to relate to the serving size. Use the list below as a general rule of thumb when placing portions on your plate.

visual food portion sizes
  • A woman's fist or the size of a baseball equals one serving of vegetables or fruit.

  • A rounded handful is about 1/2 cup of cooked rice or pasta.

  • The size of a deck of cards is approximately 3 ounces of meat, which is a typical serving size.

  • A golf ball or the size of a large egg is about 1/4 cup of nuts.

  • A computer mouse is about the size of a small potato.

Measuring is still the best way to ensure you have the right portion size. Once you have measured your foods for awhile you will get a better feel for the right serving sizes. If you are unsure if you have the right size, try putting less on your plate and then if you are still hungry, then go for a second “half” portion to play it safe.

USDA Portion Sizes

The US Government food pyramid is no longer. It has been replaced with the "MyPlate" icon. According to the "MyPlate" there are six food groups which should make up your daily meals. These groups include grains, vegetables, fruits, oils, milk and proteins. Vegetables should take up the largest portion of the plate. The proper food portion sizes you need for each of these groups will depend on your age, gender and level of activity.

Use the links below to go to the specific food group or just scroll through the page.

Grain Portion Sizes

Foods in this group are made from wheat, rice, cornmeal, oats and any other cereal grain is part of the grain food group. Typical foods made from these grains include pastas, breads, cereals, tortillas and grits just to name a few.

grains portion sizes

These foods are made with either whole grains or refined (processed) grains. When selecting your portion sizes from the grains group you should aim to make them whole grains versus processed.

The less processing the more nutrients you will get from your foods. During the processing of grains, valuable nutrients are removed like dietary fiber, iron and many B vitamins.
