Protein Intake – How much should you be eating?

Protein Intake – How much should you be eating?

You probably already know that protein is one of the three macronutrients that we find in the foods we eat. Carbohydrates and fat are the other two. Protein is typically thought of as the ‘muscle builder’, and of the three macronutrients, protein requires the most amount of energy to digest. So, if we’re looking to get stronger and burn more calories, more protein must be better, right? Well, maybe up to a certain point. But too much of any macronutrient can certainly throw our bodies out of whack and cause us to hold on to excess body fat. So what exactly is the optimal protein intake for our bodies when we want to look and feel our best?

Why do we need Protein?

Proteins are biomolecules made up of multiple molecules called amino acids that have all been linked together. Proteins help make up the majority of certain tissues, like organs and muscle and even your hormones. They help our cells do the work they need to do to grow and survive through their important roles as enzymes. Proteins have other important cellular functions too, like helping to transport important molecules and sending signals between cells and tissues in the body.


Here’s a quick summary of some cool facts about protein:

  • Protein has the highest thermic effect of food, which is a fancy way of saying that it uses the most energy to digest.
  • Protein intake supports lean muscle retention when your goal is to lose body fat and promotes muscle growth when you’re trying to get stronger. (Yes, you can have both at the same time!)
  • Protein is made up of amino acids, which are essential for the building of muscle in the gym and the repairing of muscle on recovery days. The creation of protein from these amino acid building blocks is referred to as protein synthesis.
  • Protein intake keeps your body healthy, strong and in a constant state of repair and renewal so you can bounce back from any tough physical challenge thrown your way.


Where do we get Protein from?

Eating protein provides essential amino acids to our nutrition; essential building blocks that our bodies are not able to produce on their own. Essential amino acids can be found in animal or plant protein sources but it can be more challenging for people who are on plant-based or vegan diets to get a sufficient quantity of these amino acids (for those following a plant-based diet check out our comprehensive guide to Vegan protein sources).

Almost all foods contain some protein. For instance, a tablespoon of peanut butter contains about 3g of protein, 1 cup of spinach contains about 2g of protein and the average sweet potato has about 4g of protein. Typically, when we’re thinking of foods that are high in protein or protein dominant, we usually think of meat, fish & seafood, dairy (milk, yogurt, cheese), eggs and protein powder. Animal based protein sources are often considered to be “better” or “healthier” because they are complete proteins, meaning that in each serving they provide all of the essential amino acids.


Recommended Protein Intake

On the low end, the recommended dietary allowance (RDA) for protein is 0.8 grams per 2 pounds of body weight, or generally, 46g daily for women and 56g daily for men. However, this recommendation is merely the minimum recommended amount you need to consume to prevent harmful nutrient deficiency, not the appropriate amount you should be eating to promote lean muscle mass and increased metabolism.

So, how do we know the right amount of protein to eat to reach our goals, and is there such a thing as ‘too much’?


Tried and tested Protein Needs

At Own Your Eating, we’ve found that 1g of protein per pound of lean body mass at your goal weight tends to be a good proportion for performance and physique benefits. For women, that works out to about 0.8g per pound, and for men, about 0.9g per pound of your goal weight. So, for example, a woman with a 130 lb goal weight should calculate her protein at 104g (130*0.8); while a man with a goal weight of 180 lbs. should calculate his protein at 162g (180*0.9).

While this may sound like a lot of protein to begin with, you’ll start to realize that there are quick and easy ways to ensure you meet your protein needs for the day.

Here’s some handy tips to get you started:


Is too much Protein bad for you?

Despite many purporting that too much protein can cause kidney damage & other harmful effects, a 2016 study determined that there were no harmful effects on measures of blood lipids as well as liver & kidney function. During the study the participants (14 resistance trained men) consumed more than 3 times the normal recommendation of 0.8g / kg a day. This also increased their overall caloric intake but it did not cause an increase in fat mass. So, it would seem that a high protein diet is not only not harmful, but does not cause additional weight gain. Keep in mind the subjects were consuming three times the normal recommended quantity which is still not a hugely significant intake in my opinion. For example, take someone who weighs 55kg (121lbs), the typical recommended minimum intake would be 44g of protein daily. This is a very low intake, the bare minimum in my opinion. If that person is to triple their intake, that would mean a daily intake of protein of 132g. This is not, in my opinion again, an excessive intake of protein for someone weighing 55kg or 121lbs. I imagine, like all things, there is a point at which an excessive protein intake is no longer beneficial, however it would seem that any potential symptoms would be individualized.

How much Protein do YOU need?

What’s the magic number, you ask? Well, everybody is different, so your optimal protein intake may be more or less than your buddy’s, but this is one of those times where there can definitely be “too much of a good thing”! If you’re not sure whether your macros are appropriately balanced then I definitely recommend having your numbers checked or working directly with a coach.
