I confess that the title of this post is stretching the truth somewhat but I needed to get your attention, you can lose weight at about a kilogram a week and you can eat the same amount as long as it's low carb and healthy.

I wrote this blog after managing to lose some weight after being told to do so by my Doctor, ok I was only 8Kg above my ideal weight and It wasn’t as difficult as I thought.

This blog gives some tips on what worked for me.

Why Shoud I Lose Weight?

Most of us reach a time in their lives when overeating and over indulgence becomes the norm, we become less active and our weight begins to spiral out of control. 

With weight gain comes a greater risk of developing high blood pressure and heart disease, just by reducing your weight by 5% and being more active you can reduce your chance of developing type 2 diabeties by 50%. 

This blog will show you how to get your lifestyle back on track and set the foundations of a healthy future in just five easy steps.

Step One – Learn the Basics of the Science of Nutrition

Low Carb Diets

Way back in the dawn of time humanity scratched an existence off the surface of the planet, all that we ate was what we could forage and what we could hunt and catch.  This expended a lot of energy in finding food and also took more energy to digest particulary before the discovery of fire.

Then came the first farmers, they cultivated their crops to make flour for bread and grew and cooked vegetables and thus began the Age of the Carbohydrate or carb. 

Carbs are easy to digest and we get a lot of energy out of them, which is why they are a bad thing to eat when trying to control your diet.  

Carbs are so nutritious that when we eat them they produce an insulin response which converts glucose from our bloodstream into a starch called glycogen which if an excess exists is converted into body fat.

If we restrict our intake of carbs our bodies begin to stop storing energy from food into fat reserves and you lose weight. 

Our ancestors consumed a lot of protein in the form of lean meat again this was harder to digest and combined with a low carb intake of salad vegetables meant they had lower risk of diabetes or cardio vascular disease.

So in order for you to have a low carb primal diet all you have to do is ditch the chips, bread, cakes, biscuits and other yummy sugary fatty food in favour of eggs, lean meat, poultry, salad, fish and cheese.

Step Two – Find the Time to Exercise

In this hectic twenty four seven digital age we are transported effortlessly to our destination by cars, elevators and travelators.  Our primal predecessors walked, ran, swam or canoed from a to b (antelope to bison). 

In order to recapture some natural fitness and to burn some calories away we need to get active, but you’ll be relieved to know that this doesn’t mean getting clad in day glow lycra we just need to incorporate some moderate low impact exercise into our lifestyle. 

Try walking to work if you live close, if not walk to a station or bus stop, try to walk fast so you are slightly out of breath as little as thirty minutes of brisk walking is enough to have a positive health benefit.  If you work in an office try using the stairs when possible, one trick you could try is instead of using the bathroom on the same floor use one on another floor and use the stairs. 

Step Three – Change Your Diet

Foods to avoid Foods to Keep
  • Bread
  • Chips
  • Breaded Chicken
  • Cakes
  • Biscuit’s
  • Beer
  • Pasta
  • Rice
  • Potatoes


  • Salad
  • Lean Meat
  • Chicken
  • Tomatoes
  • Garlic
  • Eggs
  • Cheese
  • Fish
  • Tomatoes
  • Olive Oil
  • Water

Keeping to the above needn’t be hard work just substitute what you can’t have with what you can.

Another important factor is when you eat, all too often we skip breakfast, have a light lunch at our desks and eat a lot in the evenings when we are the most inactive and least able to burn it off.

You should eat more at breakfast and during the day and little in the evenings, this way we are able to burn off more of our calorific intake.  If you are unable to adjust your eating pattern take a brisk evening walk.

Step Four – Setting Milestones

Realistically it is safe to lose a Kilogram a week, any more and you would be putting your health at risk.

Setting a target of five kilograms in five weeks is realistic but you may be easily disappointed, whatever you do share your weight loss aims with colleagues, friends and family and write an affirmation to yourself in your diary or office calendar.

My own target was to lose 8Kg which may not sound like much but try to visualise your goal in terms of 2 Litre bottles of water, imagine how heavy just one is to carry back from the store.  That 2 Litre bottle weighs 2 Kilograms, all of a sudden my target became four bottles. 

Imagine how much easier life would become without carrying around all that extra weight.

Step Five – Maintaining and Reviewing

Download a weight recording app for your smart phone and use it to keep track of progress, don’t be disheartened if your weight fluctuates from day to day as long as the overall trend is downwards you’ll be singing when you’re winning.

When you recover an element of fitness then your body will be better equipped to burn calories consumed even when resting. 

Set a target weight within your ideal BMI (Body Mass Index) and continue eating healthily when you get there, soon old habits will die hard and instead of reaching for the pizza you would rather be reaching for the salad bowl.
