A person with a tiny portion of food on a big plate.

We have started to realize portion and serving are used synonymously by most people. Unfortunately, that is incorrect. The more research we did, the more we learned we had to tighten up our definition of portion and serving sizes. We realized that as we tightened up our definitions, that serving size as a measurement was problematic. In this post, we will explain what we found and why it is a self-fulfilling problem.

Digging Right In

There is a difference between a portion and a serving even though many people consider them the same. However, they are not synonymous and that fallacy can cause many people to overeat.  We will abbreviate the AHA site here:


  • A portion is the amount of something you eat that aligns with your personal dietary needs and goals.
  • A serving is the amount of something that is suggested as commonly consumed by everyone based on the USDA’s Nutrition label.

Seems simple? How much you choose to eat vs what the suggested amount is for an item but unfortunately, it isn’t simple. Packaging, marketing, and labeling are focused on serving size and not portion size. Even the AHA will interchange the two in their writing which re-enforces the challenges of the meaning of a serving size. 

Why Does That Matter?

That messaging leads many of us on low-calorie budgets to have frustrating choices between over-consumption or wasted food. Why is that? The reason that is a challenge is that serving sizes are not tied to what we need for our DRI

According to the FDA: By law, serving sizes must be based on the amounts of foods and beverages that people are actually eating, not what they should be eating.

As people’s consumption changes, the serving size changes with it. As the serving size changes, the packaging may need to change with it. According to the FDA, this leads to overconsumption. For example, we used to drink 8 oz of soda. We now, as a population, usually consume 12. How did that happen? 

The best way to answer that is by understanding marketing, eating trends, human motivation, economies of scale, availability of products, business, affluence, health trends, etc. We feel that is outside of the scope of this post. While we feel there is a salient thread that runs through this topic, it is only a set of hunches. For now, knowing the correlation between serving size and population generalizations should be enough to make us think about stopping using serving as a size.

Portions over Servings FTW

One of the most challenging things is learning what the portion size of something is vs the serving size. If you are like us, it is a letdown to see how much less a portion of something is than its serving size. There is a silver lining to less is more we will get to. Right now, let’s talk about how to reset your visual expectations. 

A big challenge when moving from serving size is defining what it looks like so you can recognize it. What irks us is most times that information and visual representation come with opinions on ‘healthy’ alternatives. Yes, we all want to be healthy but change isn’t so simple as snapping our fingers. 

The reason it irks us is the fact that we are already taking something away when we go from servings to portions. We know through experiences that not everyone can change everything at once. To us, this is one of the reasons people who want to reduce their body size may fail to change or ride a diet rollercoaster. I know I can lose weight and eat fried chicken. Whether what we eat is healthy or not is open to interpretation but I know I didn’t cheat on my goals by doing it. 

Let us climb down from our little soap box and get back to the visualizing portion sizes which is much more helpful. We found a good way to visualize portions from the British Heart Foundation which is based on a specific calorie per day calorie budget. No matter what your goal is, this gives you a great visual guide. Eating more, eating less, eating healthy or not, here is a visual of a portion based on a calorie count. You can do the math for your needs.

With Every Cloud

Ah, yes, the benefits of knowledge. By using portion over serving size, we can more accurately buy food. Looking at your plate in a restaurant you can decide how much you need and take home. For us, this increased knowledge has had a direct impact on our food and restaurant budget. It has also made it much easier to stay on a calorie budget as we package our food accordingly. 

When we know what a portion is to us, we can buy it in bulk and then portion it into containers. This is why vacuum sealing became important to us. Restaurant meals now also generally produce a second take-home meal. If the single serving size is too big of a portion, say a 20 oz bottle of soda, we opt for something smaller. 

Wrapping Up

In this post, we discussed why we tightened up our terminology around portions and servings. Serving Size is a terrible way to understand what you need to eat for your body goals. You are essentially tying yourself to the rest of the general population’s eating habits. Not only are you tied to it, but you are adding to it by positive reinforcements as a buyer in the market. You do you is always what we preach. We believe it is hard for you to do you if you are tied to everyone else’s body goals and calorie needs.
