Porridge is a popular breakfast option.

It's quick to prepare and truly versatile.

Today, for taste and extra nutrients we threw in carefully weighed  ingredients:

porridge 30 g

semi skimmed milk 150 ml

linseeds 10 g

walnuts 25 g

12 green grapes 

half a medium banana

It was delicious and nutritious, but check out the calories.

When working with weight loss clients we often come across a belief that eating small meals more frequently is better for fat loss.

Although there are observational studies that show correlation between 'eating less and often' and lower BMI, waist circumference and decreased obesity risk, it doesn't mean that eating bigger meals less often will make you gain fat.

Studies are showing, time and time again, that for weight loss regimes based on calorie deficit, it makes no difference whether you eat 3, 6 or 1 meal per day.

As long as you are in a calorie deficit you will lose weight regardless.

Take it as great news. PrimalX nutrition advice is based on evidence and flexible dieting principles.

We will never burden you with dramatic habit changes, unrealistic expectations and goals, or advice that's not supported by evidence.

We find effective methods and solutions that support your goals and work for You.

Water has many important functions in the human body. 

💧 aids digestion, 

💧 aids nutrient absorption,

💧 dissolves and transports substances,

💧 helps remove waste, 

💧 aids immunity,

💧 protects and lubricates tissue,

💧 regulates body temperature,

💧 aids healthy brain function and more.

It is no surprise then that the human body reacts adversely to dehydration resulting in symptoms such as:

⚠️ thirst

⚠️ lethargy

⚠️ tiredness

⚠️ dizziness

⚠️ light-headedness

⚠️ headaches

⚠️ decrease in cognitive function

⚠️ dry lips, mouth, and eyes

If you are experiencing any of these unpleasant symptoms, you might be dehydrated. Check our previous post for some solutions

Maintaining healthy hydration
 
For optimal health, better performance during training and to avoid the unpleasant symptoms of dehydration, it is important to maintain sufficient day-to-day hydration.
 
Here are a few tips to keep hydrated:

Carry a bottle of water and drink throughout the day- simple as it sounds, it often gets neglected as it is not at the top of our priority list. It is an easy change you can make today to improve your health, so try it.

If, like many, you don’t enjoy drinking plain water, no problem. Try adding some fruit or sugar free squashes. You can also opt for more palatable herbal/fruit teas, sugar free sodas or sports drinks.

If you really struggle to drink enough of water frequently then you could try oral rehydration products and drinks that promote fluid retention and maintenance of fluid balance long-term such as: milk, orange juice or sports drinks. These drinks can be calorific, so if you are on a weight loss programme, make sure to keep track of calories.

Fluid intake from foods counts, so eat more foods with high water content such as fruit, vegetables, soups and stews. Yum!

  For dehydration symptoms keep an eye out for our next post.

With the human body consisting of 50-70% of water, no wonder that the sufficient liquid intake is a major health factor. 
 
Did you know that an average person leading a rather sedentary life excretes roughly 2.7 litres of water per day? That amount changes under different conditions and on an individual basis, but it is a useful reference point.
 
Daily fluid balance is, in the simplest terms, the balance between fluid losses and fluid gains.
 
We lose fluid mainly through sweat, urine, and respiration and we gain it through drink, food, and metabolism.
 
For optimal health and performance during exercise it is important to maintain daily fluid balance.
 
Keep an eye out on our next hydration post on maintaining healthy hydration.

There is more protein in broccoli than in steak... the truth behind the myth

To some extent this statement is true for broccoli has 9g protein per 100 kcal whilst ribeye steak for example has 7g protein per 100 kcal.
HOWEVER :) :) :) :) To get 20g protein from broccoli you would need to consume 770g which is equal to circa 20 servings of broccoli.
By the same token, to get 20g protein you need to eat 160g of ribeye steak.

Suddenly we arrive at a more realistic comparison between the two protein sources: there is 2.6g protein per 100g of broccoli and 12.5g protein per 100g of ribeye steak.

20g protein = 770g broccoli = 216 kcal

20g protein = 160g ribeye steak = 321 kcal

Energy Balance is an ongoing and a very dynamic balancing act between the kcal we take in from foods and drinks vs the kcal we burn through our activities.
Energy balance and weight management

If energy in and energy out are equal then you maintain weight

If energy in is greater than energy out then you gain weight

If energy in is less than energy out then you have weight loss

The concept is that simple, but like with anything in life, not that easy in practice. If you are struggling to maintain, lose or gain weight, don't hesitate to get in touch and ask for our help.
We'll work with you to get to the bottom of the issue and tailor a solution FOR YOU.

Why does fat get such a bad reputation?
Maybe because fats have the highest kcal value of all the macronutrients with 9 calories per gram.
Maybe because in the 80’s they got us to believe that all fats make us fat and are the source of all evil. Or maybe it is all those common misconceptions and the lack of understanding of good fats and the important role they are playing in our daily diet.
In fact, good fats are essential to life and here are a few reasons why you should think twice before going low fat.
UNDERSTANDING FATS- unsaturated fats
Unsaturated fats consist of monounsaturated fats (the Omega 9 that increases good and decreases bad cholesterol) such as olive oil, avocado, pecans or almonds, and polyunsaturated fats (the Omega 3 that is anti-inflammatory and the Omega 6 that is pro-inflammatory) such as flax seed, fish, h**p or canola oil.
UNDERSTANDING FATS- benefits
1. Help us maintain a healthy immune system
2. Help produce recovery hormones
3. Help us absorb certain vitamins
4. Help in production of Testosterone /Oestrogen
5. Help Body composition, mood, and libido


UNDERSTANDING FATS -Saturated fats
Believe it or not, saturated fats such as butter, animal fats or coconut oil , are not bad unless you decide to eat a pound of butter every day ( not advisable). You can enjoy these fats as part of a balanced diet and in moderation

UNDERSTANDING FATS- bad fats
Not all fats are made equal. Margarines, fried foods, pastries, and highly processed snack foods all fall under the trans fatty acids category and are pretty bad for you. Those are primarily manufactured by men/women and can lead to weight gain and increase the risk of cardiovascular disease. You should definitely avoid these in your diet!

Fats are an important macronutrient that our body utilises as an energy source and to absorb fat soluble vitamins such as D, E, K and A. Essential fatty acids support brain development and functions, help control inflammation and promote healthy hair and skin.



Dietary fats is a vast subject and we'll share some important facts with you over time, so keep an eye out!

For now here are some fat sources with kcal values that you better keep in mind if you're kcal counting. 1 gram of fat equals 9 kcal!

If you are a gym member, especially in a gym that specialises in programmed fitness training, then you might have heard about training different energy systems. But, do you know what they are and what it all actually means?

Let us start with the aerobic energy system today. In lay terms this means training with oxygen. Aerobic system is responsible for the energy production necessary to sustain everyday life, longer lasting activities as well as recovery from higher intensity training.

The aerobic system is highly adaptable and efficient. When trained effectively, it improves performance, muscle endurance, recovery, and longevity, as it has highly beneficial impact on the cardiovascular health and function.
Aerobic training involves sustaining a steady pace/effort for longer and should lead to cardiovascular and skeletal muscle adaptations.

Like with any training, it depends on your current fitness level and should be prescribed accordingly.

Understanding the total daily energy expenditure and the lingo behind it. :)

On average a person utilises roughly 70% of total energy expenditure to support basic functions such as respiration or brain functions. This is called the basic metabolic rate (BMR).

A further 15% is taken up by physical activity other than exercising such as cleaning, walking, gardening etc known as the non-exercise activity thermogenesis (NEAT).

10% is used to digest, convert and absorb food functions termed thermic effect of feeding (TEF). Which leaves merely 5% for the exercise energy expenditure (EEE).
