To lose weight, you need to burn more calories than you consume. But how do you know the amount of calories your portions contain? Measuring accurate portion sizes is key to succeed with your daily calorie intake goal.

Why accuracy is important – Calorie intake example

A typically healthy breakfast consisting of greek yoghurt, walnuts, raspberries, and honey can vary widely in calories depending on your portion.

Let’s say you put one cup of greek yogurt in a bowl, top it with a handful of walnuts, half a cup of raspberries and a teaspoon of honey. That will make an excellent breakfast consisting of 342 kcal, 10g protein, 21g carbs, and 24g fat.

But what happens if you accidentally serve yourself one and a half cups of greek yogurt (which can often happen when pouring it over into a bowl), misinterpret what a handful really is and grab as many walnuts as you can in one hand, and pour honey without measuring? Then you easily hit a 627 kcal breakfast which was not at all what you intended. Measuring and tracking food with a calorie intake calculator app is a great way to be in control of your weight loss.

How to measure your calorie intake

1. Use a food scale for accurate calorie intake counting

A food scale is the most accurate way to measure your calorie intake. Place your breakfast bowl directly on to your scale to measure the amount of yoghurt, oats, fruit, honey or whatever you choose to eat, or weigh ingredients before cooking. This way you make sure to not use more food and calories than you were planning for that certain meal.

You don’t have to use a food scale forever. After a while, you’ll learn by heart approximately how much foods weigh and whether they’re calorie dense or not.

2. Use your hand

If you don’t have access to a food scale and you want to know what a typical serving size is, try this simple method.

Typical serving sizes for:

  • Carbs – The same size as 1 cupped hand
  • Protein – The same size as 1 palm
  • Fat – The same size as 1 thumb
  • Vegetables – The same size as 1 fist

When logging the correct amount of food in your calorie diary, you’ll understand what food to eat more of and what food to avoid. You’ll also see how much more you can eat after exercising and whether your eating habits are balanced or not.

Do you need a calorie intake app?

If you’re one of those people who claims to always eat healthy, workout a lot, yet doesn’t lose weight (and have no medical conditions behind it), chances are you’re in big need of a calorie intake app. Healthy food can be calorie dense and zero calorie food can be unhealthy – it doesn’t always go hand in hand. The trick here is portion control and to prioritization of the foods you’re eating.

5 out of 5 stars

This app is so much more than just counting calories, it also keeps in mind carbs, protein and fat while creating a personalized plan for you. The quiz at the beginning was so accurate and I’ve been eating so much better even after a couple days. Never thought I would be able to do it.

5 out of 5 stars

This app has helped me gain muscle and lose fat. It can be a little tricky at first, but once you get the hang of it, you will find yourself reaching your goals faster and with more ease. One of the only fitness apps I’ve kept using

5 out of 5 stars

This is the best app I’ve tried so far - including Weight Watchers and My Fitness Pal. It finds EVERYTHING. The insights are so helpful and have made me more conscious of what I’m eating. The recipes look great, interface is intuitive and user-friendly. I just upgraded to Premium and excited to keep using this app!
