Ensure you eat enough protein by May Simpkin

Do you eat enough protein? Here’s 7 signs you may have overlooked

Protein is not only important but crucial for our health and indeed, the clue is in the name…the word protein originates from the Greek word “protos”, which means “first”. Ensuring you eat enough protein should be first and foremost when making your meal choices.

With so much attention on avoiding carbs and reducing fats, that leaves protein as a main food group to focus on. Amongst bodybuilders, sports enthusiasts and personal trainers, high protein diets are the norm with many adding protein powder supplements to an already protein-rich diet. It is often hailed as the key to weight loss and diets like Atkins, Dukan and Paleo advocate eating proteins such as meat, fish, eggs, nuts and cheese in large amounts.

However, with recent trends where many are avoiding meat, this can often inadvertently lead to eating few protein foods. As a nutritionist, whilst supporting you to achieve your health goals, my focus is always on what the body needs to ensure your health. If you don’t eat enough protein, your health and body will suffer.

It is difficult to over estimate the importance of ensuring adequate protein in the diet.

However, there is a lot of confusion as to how much protein you actually need and indeed, what foods are protein foods?

Whilst we may be aware of the non-vegan protein choices like meat, fish, chicken and eggs; knowing which vegetarian or plant-based options are available can be confusing. As a result, you may not eat enough protein if you’re following a more plant-based way of eating.


Protein is an important component of every cell in the body and it is an important building block for hair, skin and nails as well as muscle and cartilage. It is, therefore, crucial for tissue and muscle repair and a resulting deficiency if you do not eat enough protein will compromise the efficiency of this process. You also need protein to produce enzymes, hormones and neurotransmitters.

In terms of symptoms, food cravings, muscle/joint pain, poor hair/skin/nail, slow healing, prone to sickness/being ill, brain fog are all signs of potential lack of protein in the body.

But first, let’s take a look at how you can calculate how much protein you need?

According to government guidelines, your protein consumption should be 0.8g per kilogram of body weight.

For an average sedentary woman, this is around 46g of protein per day (56g for men). It is worth noting that this is a minimum daily average and should be considered a starting point; your protein requirement will be based on your personal health goals and lifestyle. Factors such as activity levels, age, muscle mass and current health status must all be considered.


How does this differ if you are sedentary or exercise a lot?


Protein consumption according to government guidelines

·      0.8g/kg of body weight

An average healthy adult with a sedentary lifestyle can aim a little higher to ensure adequate intake.

·      1.0g/kg of body weight

If you exercise regularly, your body will need more protein but it will depend upon the type of exercise.
You need protein to allow your body to repair and rebuild muscle so you will need to increase your protein intake a little.

·      1.1-1.6g/kg of body weight

However, if you’re very active and focusing on resistance training for around an hour a day, you will need to increase your protein.

·      1.2-2.0g/kg of body weight

Studies show that protein can help to increase your metabolic rate and therefore can help with weight loss.
If you’re aiming for weight loss and training/exercising around 3 times per week, increase your protein intake

·      1.2-1.5g/kg of body weight

Endurance athletes will need to ensure a higher intake of protein

·      1.3-1.6g/kg of body weight


With this in mind, if you don’t eat enough protein, your body will suffer and become aware of any compromise in these body functions can be a reasonable indicator of whether you are eating enough protein.

So, whether you’re a meat-eater, a vegan or a vegetarian, look out for these simple signs to know if you’re getting enough protein.

7 signs you’ll notice if you don’t eat enough protein

  1. Food Cravings

    Protein slows down the release of sugars into the bloodstream and therefore helps to ensure blood sugars are balanced. A low protein, high carb diet will release sugars quickly into the bloodstream. Once insulin is released to remove these sugars, cravings will kick in as blood sugars quickly drop.

  2. Muscle/joint pain

    If you don’t eat enough protein, your body will have no choice but to break down muscle to ensure its needs. This will result in weakened muscle tone, reduced muscle mass and weak joint support. Without enough protein, your body will also take longer to recover following injury.

  3. Poor hair/skin/nail health

    As these are all made up of protein, a lack of protein will manifest itself here in the first instance. Lacklustre or thinning hair, weak or brittle nails, nail ridges and dry, flaky skin are all initial indicators of lack of protein, as the body is unable to regenerate the cells efficiently to replace dead cells.

  4. Poor immune health

    Getting sick often is an indicator of poor immune health and can be as a result of lack of proteins, as immune cells are all made up of protein. Without enough protein, they cannot repair and multiply quickly enough to combat bugs and germs. Ensuring you eat enough protein will guard against this.

  5. Brain fog

    Neurotransmitters such as Serotonin and Dopamine are all made up of proteins. A lack of protein can lead to low mood, poor concentration and reduced mental alertness. These symptoms can also be exacerbated with similar symptoms of poor blood sugar balance if you do not eat enough protein.

  6. Poor sleep

    Without enough protein, hormone production is compromised and as such these imbalances will ultimately affect sleep quality and disrupt your night’s sleep. Tryptophan, an essential amino acid helps to induce sleep; eating a little protein around bedtime can help to improve sleep quality.

  7. Stress

    The release of stress hormones can increase muscle and tissue breakdown and it is important to note that this can be either physical stress (from over-exercising) or emotional stress.


Here’s the protein you should be eating:

Eating first class proteins will provide all the essential amino acids that your body needs to function properly. In nutrition terms, the word “essential” means it must come from the diet; in other words, your body cannot make these.

If you’re a meat-eater

Animal proteins are “complete” proteins as they contain all these essential amino acids, whereas plant proteins are not all complete an will need to be combined to ensure an intake of all the essential amino acids. Foods that provide all 8 essential amino acids include meat, fish, chicken, eggs and dairy as well as whole grains like quinoa and brown rice.

As a vegetarian

Eating eggs and dairy (and fish if you’re a pescatarian) will be a good source of first-class protein alongside wholegrains to ensure variety in food choices. It is worth noting that whilst grains do contain all of these essential amino acids, they are in varying amounts and therefore combining these foods in reasonable quantities will ensure adequate intake of each.

As a vegan

It is essential to ensure protein from a variety of sources mixing, for example, soy foods and grains or beans/pulses at each meal, otherwise, it is more difficult to ensure adequate intake of the essential amino acids the body needs. Combine sources like whole grains, beans/pulses such as chickpeas and lentils with soybeans, nuts and seeds will provide varied amino acids for optimal health.

Should you be eating protein at every meal?

Eating good quality protein at each meal will ensure the body has access to sufficient protein – throughout the day – for its needs. As protein is a complex nutrient, it will require more energy to break down and can, therefore, boost your metabolic rate, helping with weight loss.


Should you be eating protein if you want to lose weight?

As a complex nutrient, protein takes longer to break down and process during digestion and thus there is the additional benefit of helping you to feel fuller for longer, curbing cravings and reducing appetite. This is all helpful if you’re trying to lose weight.

How about if you exercise?

If you’re exercising, you will be using this protein to build muscle. In fact, the only way to build muscle is through exercise, not by eating more protein. Thus you will need to ensure good protein and athletes need to be more focused, as they will need more protein to build muscle.

A 2018 review confirms that there is good evidence to suggest that eating protein pre and/or post workout helps significantly with muscle building. It has also been shown that protein intake immediately after exercise (within 1 hour) plays an important role in ensuring optimal recovery and generally optimising physical performance.


If you eat enough protein at one meal, will it carry over for the day?

Whilst it is important to eat enough protein for the body to function well, eating too much protein doesn’t necessarily ensure that the body will benefit from this extra protein. The body will only use what it needs and it will continue to do so throughout the day, using the amount it needs from each meal and discarding the remaining protein.

Research has shown that eating your protein spread out throughout the day is more effective when building muscle than eating the majority in the evening meal.

Thus, eating good quality protein at each meal will ensure the body has access to sufficient protein throughout the day for its needs.

Why is it important to get different sources?

The body relies on the eight essential amino acids for function and these must come from the diet. From these, the body can make up the remaining proteins to make up 22 in total.  Consuming a variety of protein foods will ensure a good combination of these essential amino acids.
