Micronutrients are one of the major nutrients the body needs alongside macronutrients. However, the body needs smaller amounts compared. They consist of vitamins and minerals, which all play an important role in staying healthy and improving your performance when training. When performing strenuous exercise, it is essential that higher amounts of micronutrients are consumed due the them being lost throughout training.



Calories are a unit of measurement and therefore, they tell us how much energy is in a certain food or drink. If we don’t use as many calories as we take in, our body stores the remaining as fat. Any movement or bodily function our body makes burns calories. To maintain a certain weight, we must intake the same number of calories we burn. Exercising burns a lot of calories; it is essential enough calories are consumed to allow us to maintain bodily functions and stay alive. On the other hand, when trying to lose weight it is essential that more calories are burnt than consumed, this is known as a calorie deficit.



Macronutrients, also known as Macros, are nutrients that the body requires in large amounts daily to function adequately. There are three macronutrients; Protein, Carbohydrates and Fats.


Healthy Fats

The fitness food keyword fat is one you may hear often.  Fats have a bad reputation and people assume that eating fats will make you gain weight. While this is true to an extent, ensuring your body consumes the right amount of healthy fats is essential to anyone looking to workout. The body uses fat as energy and therefore, consuming enough allows bodily functions to happen efficiently and keep us moving.

Healthy fats are those that are less calorically dense as other fats. These healthy fats are known as Polyunsaturated fats found in foods such as sunflower oil, some nuts and seeds. Monounsaturated fats found in olive oil, avocados and nuts; and Omega Fatty acids which are found in fatty fish such as salmon and nuts such as walnuts. When it comes to losing weight, cutting these fats out of your diet should not be considered and these beneficial fats have shown to cut belly fat, reduce cravings and reduce inflammation.

Proteins are amino acids that make up every cell in our body and no bodily function can happen without it. It is essential that you consume the right amount of protein to stay healthy and reach fitness goals. Protein enables the body to heal more efficiently, therefore after a hard session at the gym, it allows the body to recover. This means that it’s not just for those looking to grow giant muscles. It is also essential that those looking to lose weight also consume enough protein, when the body isn’t consuming enough it will begin to pull fuel from other areas of the body such as bones, organs and the heart.

When you take part in any physical activity, your muscles are being worked to the point where the fibres that they’re made up of tear. This tearing is essential to making them bigger and stronger.


Whey Protein

Not all proteins are the same and some provide better quality sources than others. Milk contains two proteins Whey and Casein. Through a separation process, Whey can be isolated from the milk. This is because Whey provides a high amount of essential amino acids that can be absorbed quickly by the body. Once separated from milk, it goes through various processes to be sold as a protein powder; this includes adding flavours to make it delicious. Whey protein can be used by gym goers and those looking to lose weight as it is a convenient way to add more protein to your diet.

The main role of carbohydrates is to provide energy to the body, it should be its main source of energy when living a balanced healthy life. When exercising it is essential that it is consumed to provide the brain and muscles with enough energy to increase overall performance and prevent fatigue.

Carbohydrates can be found in 3 forms; sugar, starch and fibre. Starchy foods are those found containing plants such as rice, potatoes, bread and pasta and are the most essential when relating to the gym and a healthy diet.

Carbohydrates are stored as Glycogen within the body in stores. If these stores are not fuelled before a workout then it will result in feeling tired and sick during the workout. However, any unused glycogen will be converted into fat for long term storage of energy. Because of this, carbs have been portrayed as being bad for anyone who is looking to lose weight. However, if you ensure you take part in enough physical activity to burn the amount of carbohydrates consumed then carbohydrates can allow you to feel awake and alert and will not make you gain weight.
