How to eyeball your portion sizes without counting calories

When we’re trying to lose weight one of the first things we do, is control our portion sizes. Some people do this by cutting out complete food groups (e.g. take carbs off the menu), while others may become very particular by weighing and measuring everything before they put it in their mouth.


Of course, portion sizes are a factor when it comes to weight loss, especially as too much of some foods can mean a calorie intake that leads to weight gain, rather than weight loss. But cutting out food groups, being obsessed with counting calories, or measuring and weighing food is not the best approach.


What happens when you restrict food or count calories


Cutting food groups puts your body at risk of nutritional deficiencies, which can compromise your immune system, and prevent your body from functioning properly, therefore making it harder for you to lose weight. It also sets you up for emotional and binge eating, which will cause you to sabotage your weight loss efforts. To fully understand why food restriction backfires, read our blog Why food restriction, food rules and diets are making you overweight.


The other problem about weighing, measuring and counting calories is that this only perpetuates dieting behaviours like perfectionism and the diet mindset, which keep you trapped in the dieting cycle, and prevents you from losing weight. To fully understand how diets impact you, be sure you read How diets steal your health and happiness.


However, there is a better way to control your portions without the stress and without the need to carry scales and a set of measuring cups around with you, where ever you go, or even opening a calorie-counting app.


However, before we show you how to eyeball your portion sizes, let’s take a look at what kinds of foods you should be eating for healthy, sustainable weight loss that will improve the way you look, feel and function.


Foods for healthy weight loss


We have already written a blog that outlines foods that help you lose weight, so we’re not going to rehash that here. To find out what they are and why they help, read The 14 best foods to lose weight.


But for the purposes of illustrating how to measure portion sizes without calorie counting, it’s important that we understand the basic foods that help with weight loss. These are:


  • Proteins
  • Vegetables
  • Carbohydrates
  • Healthy fats.


A better way to gauge your portion sizes


One thing that many diet plans have in common is that they require you to measure or weigh your food, or even do complicated maths trying to calculate the caloric intake of certain foods. Even those apps that calculate the number of calories in your meal require you to know how much you’re eating (e.g. you need to weigh and measure). This just makes weight loss more complicated and stressful than it needs to be.


A much simpler way to gauge portion sizes that doesn’t involve time-wasting measuring and counting is to use your hand. Studies have shown that using the hand model as a guide to portion sizes can be useful.(1)


Here’s how it works.


Your fist


A closed fist = approximately 1 cup


The front of your closed fist = approximately ½ cup


Your hand

A cupped hand = approximately 1 cup


Your palm


Your palm = 1 serving size of protein


Your thumb


From the tip of your thumb to the base of your thumb = about 1 tablespoon


Your fingertip


Your fingertip = 1 teaspoon


How big should my portion size be?


Obviously how much you need to eat depends on a number of factors, including your sex, height, weight and your body transformation goals. So, the information below is a general guide only.




Protein keeps you full for longer, helps you build muscle (which helps you lose weight), and will help you recover effectively from your training. Good sources of protein include lean meat and poultry, and fish and seafood, eggs and legumes.


Men should aim for 2 palms of protein, while women should aim for 1-2 (depending upon their goals).




Vegetables are your best friend when it comes to weight loss. Not only are they low in calories, they help keep you full and provide you with energy (yes, they are a source of carbohydrate), and essential vitamins and minerals. When it comes to veggies, the more colour the better. Unfortunately, most Australians fail to eat the recommended 5 serves of vegetables each day.


It’s very difficult to eat too many vegetables so aim for 2 fistfuls at most meals.




While our body needs carbohydrates to function properly, we don’t need as much as most people think. Most people’s meal plates are primarily made up of carbohydrate which is usually too much.


Men should aim for 2 cupped hands while women should aim for 1 cupped hand (depending on their goals).


Healthy fats


Consuming healthy fats is just as important for weight loss, as eating protein and vegetables. Omega-3 fats (found in oily fish, flaxseeds and flaxseed oil) are particularly important as they reduce inflammation which can lead to unwanted weight gain, and a host of chronic illnesses. Other good sources of fat include olive oil, avocado, nuts and nut butters. Quantities you should aim for include:


  • Olive or flaxseed oil = between 1 fingertip and 1 thumb
  • Flaxseed = 1 thumb
  • Nuts or avocado = 1 handful


Once you get the hang of it, this method of eyeballing your portion sizes will help you manage your portions without the hassle of counting, weighing or measuring. It’s also a great way to keep your portions in check when you’re eating out.


Stop counting calories and start losing weight
