Understanding Macros And How To Use Them

By the end of this article (blog) you will be able to understand what macronutrients are and how to use them in your daily life.

Macronutrients or 'Macros' are a group of nutrients that are found in food that give us energy. The three macronutrients are;




No matter what training plan, lifestyle or diet you have, all three are essential in our diets for a healthy, happy life.

So when someone is tracking their macros, what it means is they are counting the grams of protein fats and carbohydrates in their diet.

This will be based on a calculation of their overall caloric intake ( how many calories they are able to have in a day ) and the way they split their macros. There is no one size fits all approach with this, as every persons genetic make up will be slightly different. However there is an acceptable macronutrient distribution range (AMDR)

45–65% of your daily calories from carbs,

20–35% from fats

10–35% from protein.

Every body is slightly different in which percentage works for them and for many it is a case of trial and error.

Though a large percent of us will already have a high carbohydrate diet and this does not mean it is a bad thing. Unless you're on a specific diet such as keto and depending on what types of carbohydrates you are having such as simple or complex.

However it is important that we do not neglect any of our macros as it can lead to many issues.

So it is important you understand the benefits of each macronutrients and what it does to your body on a cellular level.

.Fiber is also a carbohydrate that aids in digestion, helps you feel full, and keeps blood cholesterol levels in check.

A carbohydrate-deficient diet may cause headaches, fatigue, weakness, difficulty concentrating, nausea, constipation, bad breath and vitamin and mineral deficiencies.

You want to mainly focus on having complex Carbohydrates as they have longer sugar molecules, which takes longer to break down and supplies a steady flow of energy which reduces a sudden spike in insulin which decrease the risk of becoming insulin resistant.

Complex carbohydrate are things such as whole grains, beans and vegtables

Simple carbohydrates are things such as highly processed foods, fruit juice and foods where sugar or corn syrups, glucose fructose and sucrose have been added.

The guided daily recommend amount of protein is 46grams for women and 56 grams for men. However this is a guideline for the average person, so it is not tailored to the individual. Many factors need to be taken into account such as; age, training intensity, genetic make up the list goes on. which is why working out your macros is a great way to Taylor your diet for your specific needs.

some sources of protein are salmon, tofu , chicken eggs and dairy products. Note that it is always best to get high quality products to ensure high quality protein and trying to stay away from substitutes such as protein bars and other highly processed foods with added protein such as cereal and sticking to the more natural sources where possible.


  • helps the body absorb vital nutrients

  • helps give you energy

  • supports cell growth

  • keeps cholesterol and blood pressure under control

There are two type of Fats which are saturated and unsaturated

Saturated fats are primarily found in animal products such as beef, pork, chicken and high fatty dairy foods. it can also be found in butter cream cheese and highly processed baked good such as cakes and biscuits. The concern with these fats are that they produce more bad cholesterol which can form plaque in the arteries and increase risk of stroke or cardiovascular disease.

unsaturated fats have many health benefits and can be broken down in to two categories monounsaturated fats and polyunsaturated fats.

Good fats come mainly from vegetables, nuts, seeds, and fish. They differ from saturated fats by having fewer hydrogen atoms bonded to their carbon chains. Healthy fats are liquid at room temperature, not solid.

Good fats help keep the brain healthy as well as lowering bad cholesterol. The association between healthy fats and healthier brains may be related to inflammation as diets high in saturated fats appear to raise inflammation.
