How does junk food contribute to our obesity epidemic?

Obesity is a global problem defined by the World Health Organisation (WHO) as an abnormal or excessive fat accumulation that can have a negative impact on health.

So, what role does junk food really play in this problem?

WHO state the most fundamental cause of obesity is when there is "an energy imbalance between calories consumed and the amount expended".

Junk food is high in calories but low in nutritional value. It often contains high amounts of sugar and fat without providing many minerals, vitamins or nutrients that are essential to good health.

However, more and more people are opting to eat junk food as it appeals to our base needs. Why? Junk food is able to stimulate the reward system in our brain, which means we are primed to consume more of it. Your body releases "feel-good" chemicals when you eat these foods, so it's no wonder they have increased in popularity!

In order to reduce your risk of obesity, it is essential to reduce your intake of these unhealthy processed foods and replace them with fruit, vegetables, legumes, whole grains and nuts.

Excess sugar and fat can accumulate in your body causing weight gain. This has other affects on your body - it can increase your risk of developing type 2 diabetes, heart disease and arthritis.

Doing a 28 day detox program can help get you on the right path towards leading a better lifestyle. You may lose weight afterwards and feel generally happier and healthier. Plus, you can learn to get pleasure from eating healthier treats and wean your body from its sugar and fat addiction.

In addition to this, it is important to exercise if you want to reach or maintain a healthy body mass index (BMI). You must work off the energy you have eaten in order to maintain a steady and healthy weight. BMI is the measurement generally used to calculate obesity and it calculated by dividing your weight in kilograms by your height in metres squared. A BMI between 18.5 to 24.9 is healthy.
