Basics of Nutrition

If you want to lose weight effectively you really need to know the basics of nutrition to understand what your body needs, how much and when.

In my last post I discussed the basic points of weight loss with you and I hope you found it informative. Below is a link to that post if you missed it and would like to read it before this one, as I am going to go a little more in-depth and it is always better to start with the basics and work your way up (especially for me!)

You may have seen a motivational quote floating around which reads:

You can’t out train a bad diet 

Don't Give Up

This quote is so true!


You can exercise as much as you like but if you are not eating right then you may as well give up on your weight loss journey or your fitness journey.

But that is not what I want you to do!

Don’t Give Up!

You may not even realise that you are not eating well, you may have been passed information on a diet by someone or seen in on facebook or pinterest and went for it blindly, hoping and wishing that it would work.

I’ve heard of a lot of these; the apple diet, the grapefruit diet and the maple syrup diet to name a few.

Healthy eating made easy

Most of those ‘fad’ diets are not good for you, they can even cause harm in some cases and they are certainly not a good idea if you want long term weight loss or you want to improve your fitness.

As I mentioned in my last post you need to work with your body and not against it, and it becomes much easier if you understand what your body needs.

Okay then, let’s get started!

Why is good nutrition important?

Nutrition is so important because it is the most basic of your body’s needs.

You need food to grow, to repair and to maintain your body.
Good nutrition carries with it the following benefits:

  • Provides you with the energy you need to live your daily life.
  • Helps your body to stay within a healthy weight range.
  • Helps to delay the aging process of your body.
  • Helps your body to fight disease.
  • Helps to keep your teeth and gums healthy.

Nutrition also:

  • Helps to prevent many diseases.
  • Improves your physical fitness and endurance.
  • Improves your mental well-being.
  • Helps your concentration.
  • Helps to lift your mood.

If you do not have good nutrition, you won’t get all the benefits listed above.

Do you suffer from Malnutrition?

You may think when I mention that word that it only applies to third world countries but in actual fact, malnutrition is a worldwide problem in both undeveloped and developed countries alike.

Malnutrition is split up into two categories:


Under-nutrition is where a person is not absorbing or consuming enough nutrients to cover their energy or growth needs or to keep their immune system maintained.


Over-nutrition is where a person consumes or absorbs too much of certain nutrients, particularly the macronutrients being protein, carbohydrates and fats.

So you could be suffering from malnutrition and not even know it, even if you are overweight. If you are lacking in the nutrients your body needs, you are suffering from malnutrition.

What are the Essential Nutrients your body needs?

What Are the essential nutrients your body needs_

Your body needs certain essential nutrients for you to live and these are the following:

  • Water
  • Proteins
  • Carbohydrates
  • Fats
  • Vitamins
  • Minerals
  • Fibre

Your body needs all of these in certain amounts in order to function properly. These certain amounts are subject to change depending on your age, sex, as well as if you are pregnant, are suffering from an illness or if you are injured.

Why do you need water?

You need water to live, you need water for your body to function and many more reasons! I have a whole separate post about drinking water so I am not going to repeat it all here, just read the following post:
