Diet or exercise for


weight loss?


If you are trying to lose weight through diet or exercise you have made the right decision. Being overweight is the result of an energy imbalance. The maths is easy: If the energy put into your body exceeds the energy you expend and this leads to excess kilograms. In theory the solution is easy too, eat less and exercise more but how do you know if you’re getting the balance right?

Here’s what you need to know:

  • Everybody has a slightly different estimated daily energy requirement, measured in kilojoules (or calories).
  • If you exceed your estimated daily energy requirement you will gain weight.
  • We have 100% control over the ‘energy in’ half of the equation. This is the food and drinks you have each day
  • We have around 15-30% control of the ‘energy out’ half of the equation. This depends on the frequency, intensity, time and type of exercise you do
  • Therefore the most effective weight loss plan is to combine exercise with a healthy diet that does not exceed you estimated daily energy requirement.
  • Your estimated daily energy requirement is calculated according to your age, sex, weight, height and activity level
  • For example a 30 year old female weighing 65kg who exercises for 60mins, 3 times per week would have an estimated daily energy requirement of approximately 8700kJ/day

 Being a healthy weight, keeping active and eating a healthy diet will help you to achieve good health throughout life and will reduce your risk of obesity, heart disease and diabetes. Equally importantly being a healthy weight, exercising and eating a wide variety of nutritious foods will help to increase your energy levels and keeps you feeling and looking good.  

Have you got the balance right?
