Every day you walk down the street it is becoming more and more apparent that the average person is becoming larger and this trend has escalated over recent years. Why are they getting fatter? Here are some reasons...

Being overweight, or obese, has now moved from a social nuisance and domestic embarrassment to an official disease. The American Heart Association has announced obesity is a major risk for heart disease.

Obesity itself has become a major and dangerous epidemic. More than 70% of US adults are overweight and that figure is rapidly increasing.

What do most people do to rid their body of unwanted fat? They diet! Dieting is now a trillion dollar industry and just about every month a new diet is announced. If you do have weight problems how do you find a diet that is safe, effective and sustainable?

What you do is try to find a diet that includes a variety of foods that you can live with comfortably. You have to take a long-term view and include plenty of exercise. A good diet is one that supplies all of the essential vitamins and minerals, and is not high in fat or protein.

Research on people, who have successfully lost a lot of weight and kept it off long term, shows that the vast majority succeeded by consuming a low fat diet high in fibre coupled with strength training and cardiovascular activity.

Be wary of diets that

Ban a specific food group

Promise a quick fix

Replace a balanced meal with a drink or a snack bar

Make recommendations based on single studies

Make recommendations to help sell a single product

Excess weight does not appear overnight and nor will it disappear overnight! In fact the faster you lose weight, the more likely you are to pile the pounds back on.

These nutrients include carbohydrates, proteins and fat and are all present in the food we eat on a daily basis.

The foods containing these nutrients are cereals, legumes, nuts, vegetables, fruits, milk products and flesh foods (fish, meat and poultry).

We need all these nutrients to live and thrive and since we receive them through the food we eat, our food must be well balanced and in the proper proportions. Food is a fuel; the body requires this fuel for energy, which is measured in fats, carbohydrate and protein.

Each of these nutrients provides different amounts of energy and these are measured in calories.

Nutrient Calories per Gram

Carbohydrate 4

Protein 4

Fat 9

Let's look at carbohydrates first, carbohydrates supply energy for our body, they provide fibre for the prevention of disease and taste and texture to food. They are found in cereals, potatoes, fruits and vegetables.

They come in two basic forms, simple and complex. Simple carbs are easily identified by their taste and are sweet. Complex carbs, such as potatoes are pleasant to the taste buds, but are not sweet.

They are then divided into two groups, high fibre and low fibre.
