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 for both male and female, 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. Calculating your daily calorie intake with Lifesum also helps you choose proper, filling meals which will ensure a healthy weight loss journey.

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 to determine how much to eat.

Typical serving sizes for an adult man or woman:

  • 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 in-app calorie diary on your iPhone or Android, 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 prioritization of the foods you’re eating. Lifesum is available in App Store and Google Play and will calculate the amount of calories you should consume per day in order to lose weight, be healthy or build strength.

Much easier to use, love the interface and how it has recipes and keeps me on plan. I upgraded to the full version, no regrets! I’ve tried many apps and in my opinion this one is the simplest to use and guides my choices!

I started using the app on a Monday and tracking my food and being super honest. It’s Thursday and I’ve already lost 3 lbs. I’m so so so happy and will continue using it throughout weight loss journey. It’s really user friendly as well!
