It’s time to learn how to portion control!

There are all sorts of “tips” and “tricks” out there, but today we’re going to show you the best method.

What makes me so confident?

For many of our Online Coaching clients, we create portion control strategies for weight loss that don’t suck. Today, we’ll share them with you too!

Here’s what we’ll cover:

Let’s do this thang!

What Are 5 Methods for Portion Control?

This photo shows a LEGO in front of his food chart, where he determines portion sizes.

As you might know from our “How to lose weight” guide, the key to sustainable weight loss is getting ourselves to consume fewer calories in a way that doesn’t make us miserable. 

Because our brains and bodies are complicated emotional disasters, there are some tips and tricks we can implement to protect us from…ourselves.

4 Strategies for Portion Control:

  1. Use smaller plates. Folks will often eat what’s placed in front of them, so using smaller dinnerware has been shown to help people eat less.[1]
  2. Drink a glass of water before your meal. If you chug a glass of water 30 minutes before you plan on eating, the H20 will take up some room in your stomach. This might help you eat less.[2]
  3. Take it slow. It can take about 20 minutes for your body to come around to the fact that it’s full, so slowing down your meals can help you eat less.[3]
  4. Use a food journal. Recording everything you eat and drink is a great way to become aware of portions, which can help you control them.[4] In fact, one of the first missions we have Nerd Fitness Prime members complete is creating a food journal. 

All of these methods will work to some extent, and they’re good to keep in mind and also practice.

However, nothing will get more consistent results than actually learning the number of calories in the food you eat (Portion Control Tip #5)!

This is our number one recommendation for how to lose weight

A gif from the Simpsons that says "interesting."

Study[4] after study[5] after study[6] shows that our bodies obey the laws of thermodynamics and that in order to lose weight, we need to burn more calories than we consume regularly.

  • When you consume more calories than you burn, your body tends to store those extra calories as fat (weight gain).
  • When you burn more calories than you consume, your body will pull from fat stores for energy (weight loss).

However, as we point out in our Calories In, Calories Out guide, determining your exact “calories in” can be a real pain. Not only that, but many people with certain personality traits can become neurotic about tracking every single calorie. They worry if they go 1 calorie over their daily allotment. 

So, what’s a nerd to do? 

Unless you’re going to weigh out all your food (something I’ve done before) and be militant about tracking, is it possible to “track” your food with a high level of accuracy without having it take over your life?

The answer: yes, by getting darn good at estimating! 

Portion Sizes: How to Portion Control (The Best Method)

A plate that that contains a portion of protein, healthy carb, veggies/fruit, and unsweetened drink.

You already carry with you the best method for portion control.

Your hands!

This gif shows the Terminator looking at his hand, who realistically doesn't have to worry about portion control.

Even if you have robot hands.

We’re going to use them to build a healthy plate, as shown above.

The “Nerd Fitness Healthy Plate” was originally published in our Guide to Healthy Eating, which was inspired by our friends over at Precision Nutrition

We’re not going to worry about being exact. 

It’s really hard to be precise anyway.[7]

However, using your hands as a tool for portion control provides a “good enough” strategy that can help your food intake:

This graph shows servings sizes for protein, vegetables, carbohydrates, and fats, based off the size of your hand.

As you can see, we’re going to focus our portion control strategy on:

  • Protein
  • Vegetables (technically carbs, but important enough to deserve their own category)
  • Carbohydrates (think starches and fruit)
  • Fat

Each macronutrient will correspond to an area of your hand, to give you a sense of what a proper portion size should be. 

We’ve learned that using your hand as a guide is the most helpful strategy for portion control:

  • You might not always have access to small plates.
  • You might forget to drink water before each meal.
  • You might have a short lunch break without the luxury of eating slowly.
  • You might grow tired of logging all your food intake.

However, having an intuitive sense of what foods should be eaten in what portions will help you level up your healthy eating.

When in doubt, match the food in front of you to your hand and carry on.

Let’s break this down a little by talking about protein and veggies. 

What is the Correct Portion Size Part 1: Protein and Vegetables

The above video is taken from Nerd Fitness Prime, as part of our NF Kitchen series.

In it, Coach Lauren and Justin discuss the two most important parts of every meal: 

  • Protein
  • Vegetables

Here’s something that might seem counterintuitive: our #1 recommendation for portion control isn’t about limiting food. Instead, make sure you get a proper serving of protein and vegetables every time you sit down to eat.

In other words, when you begin your healthy eating journey, don’t even worry about nixing any specific food. Just make sure you are leaving plenty of room for protein and vegetables.

A serving of protein is about the size and thickness of your palm:

A serving of protein should be about the size of your palm, like so.

Protein can come from any number of sources, including:

  • Meat (steak, bison, pork).
  • Fowl (chicken, turkey, duck).
  • Eggs![8]
  • Fish and shellfish (salmon, tuna, shrimp).
  • Legumes (black beans, chickpeas).

Not a meat-eater? Read our massive plant-based guide!

A serving of veggies is about the size of your fist:

A serving of veggies should be the size of your first (or greater).

Here’s a quick, non-complete list of veggies that can fill half your plate:

  • Broccoli
  • Broccolini
  • Cauliflower
  • Spinach
  • Kale
  • Spaghetti squash
  • Brussels sprouts
  • Zucchini
  • Cucumber
  • Carrots
  • Onion
  • Asparagus

When it comes to learning portion control, start by making sure you eat enough protein and vegetables.

How much?

As we discuss in our protein guide, when building a plate aim for the following amount of protein:

  • Dudes: 1-2 servings (6-8 oz or about 170-228 g): two palms
  • Dudettes: 1 serving (3-4 oz or about 85-114 g): 1 palm.

For vegetables, in practice you can probably eat as much as you can stomach (the fiber will likely slow you down), but aim for about 2 fist fulls at most meals, or about half your plate.[9]

Here’s why you should prioritize protein and vegetables if you’re struggling with portion control:

  • Protein. Eating enough protein will assist your health as you age.[10]Plenty of protein will also help you retain and grow muscle.[11] Plus, prioritizing protein will help you stay full and satiated between meals.[12]
  • Vegetables. Veggies are both high in nutrients and low in calories, which makes them ideal for a healthy plate. Plus, the fiber will not only help your health, it’ll also keep your indoor plumbing in proper order.[13]

In the video that kicks off this section, Coach Justin makes a great point: aim for a little better than you are today.

Meaning if you don’t really plan your meals at all, start by having ONE meal include a good protein source and some veggies.

So maybe you make chicken stir-fry this week. 

Once you have that win under your belt, you can aim for doing a little bit more next week (TWO meals that include protein and veggies).

We’ll close out today’s guide with some more ideas on how to get going.

Before we get there, we need to talk about what else can go into your healthy plate. 

What is the Correct Portion Size Part 2: Carbs and Fats

After making room on your plate for protein and vegetables, what’s next?

As Coach Lauren and Justin mention in the Nerd Fitness Prime video above, it’s time to include some healthy carbohydrates and fats!

Depending on what fitness camp you find yourself in and your history of “dieting,” eating carbs and fats might make you nervous. 

But as Coach Lauren points out, they have a purpose on our healthy plate! You just need to portion them out correctly.

A serving of carbohydrates is about two hands cupped together:

Showing you a serving of carbs

If it’s uncooked, it’s about half the size, so one cupped hand.

Examples of healthy carbohydrates:

You also want to make sure you’re including healthy fat in your diet too.

Fat is actually the most calorically dense macronutrient, so comparatively it’ll take up less room on your hand.

Here is a serving of fat, roughly the size of your thumb!

A serving of fat should be about your thumb!

Healthy fat can be found in foods like:

  • Avocado 
  • Almonds 
  • Walnuts
  • Macadamia nuts
  • Olive oil
  • Almond butter 
  • Peanut butter

The reason people call it “healthy” is because the fat is unsaturated, although science has recently come around on saturated fat too in the correct amounts.[14]

We cover this in detail in our Guide to the Keto Diet.

Saturated fats can come from things like:

  1. Whole milk
  2. Full-fat dairy
  3. Coconut oil
  4. Grass-fed butter
  5. Lard
  6. Fatty cuts of meat

When it comes to portion control, we need to pay close attention to carbohydrates and fats, because this is where people have the tendency to overeat. 

However, that doesn’t mean we want to completely ditch both food groups either. 

A scene from the Princess Bride where the grandpa says "wait."

Here’s why you need to eat these two macronutrients:

  • Carbohydrates. Did you know fiber is a type of carbohydrate? Yep. As we mentioned earlier, you need plenty of fiber for good health.[15] Carbs are also a great source of quick energy, especially fruit.[16] 
  • Fats. Some nutrients like Vitamin A are fat-soluble, meaning they are best absorbed alongside some fat.[17]Fat will also help you feel full, which can help with overall portion control for the day.[18] While a little goes a long way, you wouldn’t want a “zero fat” diet.[19]

Just be careful here.

When we analyze the diets of our coaching clients who can’t seem to lose weight, it’s almost always because they are overeating carbs or fats.

If you find yourself in this group, take a look at your hand the next time you sit down to eat:

  • How much pasta are you serving yourself? It should fit within your cupped hands.
  • How much olive oil did you place on your salad? It should be about the size of your thumb or a tablespoon. 
  • How big is your serving of peanut butter, REALLY? One serving, a tablespoon, is about the size of a walnut:

This photo shows a serving of peanut butter, which is about the size of the walnut next to it.

Remember: you don’t have to get this perfect. You just need to be pretty good most of the time.

Even just consciously thinking about if your portion sizes are under or over is a great start.

And as long as you are consistent with your measuring techniques, then you can adjust your portions based on your progress!  

You might also find some special plates or containers helpful when serving yourself. 

How to Use Portion Control Containers and Plates

One hack Coach Justin uses is simple Tupperware containers to portion control his meals:

Justin holds up the container he uses to portion control his meal.

You can also use some glass containers too if you want to get fancy:

Here Coach Justin holds up his meal, held in a portion control container.

Don’t stress about finding the perfect container that exactly holds each macronutrient you need.

The point here is that you have a quick frame of reference for portion sizes:

  • The largest portion of the container: vegetables go here.
  • The two smaller portions: are for your protein and carbs.
  • The small little holder: your fats go here.

Again, don’t stress if your container doesn’t fit this description exactly. We’re all working off estimates here, so let’s focus on the big picture.

These are some cool glass containers if you’re looking for something to buy.

How to Control Portion Sizes When Eating Out

This photo shows a LEGO looking at a dog, who probably wants a portion-controlled taco.

An area of concern when attempting to portion control is dining out.

It seems like restaurants serve you twice the amount of food that you need.

Here’s what Coach Justin does in the situation: ask for a to-go box as soon as you place your order.

Yeah, it’s a little weird, but as soon as you get your food, place half of it in the container.

Boom! An extra meal for later. 

Since this adorable dog portion controls, he's walking home with his meal for later.

Another thing to consider: restaurants want you to leave feeling full.

They often do this by piling on the carbs. Think extra bread, lots of rice, plenty of pasta, etc.

So it might make sense to split these portions in two, and you’re set for lunch the next day.

Also, if you get hungry after eating only half your meal, no problem. Just eat the other half. Even if you’re still at the restaurant.

The point is to consciously think about how much you’re eating. A break halfway through can be used as a decision tree: 

Should I keep eating?

This question alone can help with portion control.

One last thing: we know eating out at restaurants is often a family or friend-bonding experience, so we’d prefer you ENJOY the night. Food is more than just calories. 

Just plan for it! If you eat a really large dinner for a celebration, eat slightly smaller portions for the next day or so and your body will be right back on track. 

How to Portion Control for Weight Loss (Next Steps)

In the video above, Coach Lauren and Justin walk you through eating a Nerd Fitness Healthy Plate IRL (In Real Life).

It’s all well and good to build a healthy plate at home, but…

  • What if you’re at a restaurant? 
  • What if you need to order a sandwich?
  • How about pizza?

Here are some tips from the Coaches for portion control IRL:

#1) How to Portion Control a Sandwich

The trick here is to pack in as many vegetables as you can. Yeah, you’re probably not going to get two fist fulls in, but you can squeeze in a lot of spinach, onion, sauerkraut, and tomato (yeah, it’s technically a fruit, whatevs) on your sandwich. 

  • Your carbs can be some type of whole-grain bread (you can do an open-face sandwich if you want to limit this). 
  • Your protein can come from some turkey. 
  • Your fat can be a little avocado. 

This is a gif of an avocado


You now have a turkey sandwich that matches our healthy plate strategy.

#2) How to Portion Control Chili or Soup

This can be a little tougher when everything is mixed together.

If you’re making it yourself, perhaps you measure out your hand portions as you cook.

  • Put a palm-size portion of ground beef in.
  • Your vegetables can be onion, garlic, and tomatoes (again a fruit, but who cares).
  • Your carbs can be pinto and/or kidney beans.
  • Your fat can be a little bit of cheese sprinkled on top.

Sure, maybe you’re doing less than two fistfuls of vegetables, and more than a cupped hand of carbs (beans).

It doesn’t matter. Again, the point is you’re putting a little thought into proper portions.

If you’re eating out and ordering soup or chili, maybe just think of the end product in mind:

“After portioning everything out, it should be about two fistfuls of food. So that’s what I’ll eat. Everything else I’ll take home.”

#3) How to Portion Control Pizza

This is a little trickier because pizza is mostly bread (carbs).

But Coach Justin has a solution for this.

First, he eats something he’s proud of, like a salad. 

Then he portions out his pizza, which if he uses his hand strategy, would be about two slices:

Justin holds up his hands, to show how he portion controls foods like pizza.

Is it perfect?


Does it help Coach Justin reach his goals and allow him to still enjoy life?


So experiment a little by creating some rough guidelines, see how you feel, and course-correct as you go.

Remember, any step you take on leveling up your nutrition is great.

Wayne is stoked that he made his small change for weight loss.

If you don’t know where to start, I actually recommend you begin by not worrying about what to take OFF your plate, but instead what to add! 

Make sure every meal you eat has a healthy protein source and a vegetable. Once you have that dialed in, THEN you can worry about portion controlling your carbs and fat.
