There are two main types of diabetes.
Type 1 is often developed at a young age and people with type 1 diabetes need insulin injections.
Type 2 often used to be known as late onset diabetes and was more common amongst older people and amongst middle-aged and older people who are overweight and obese.
Along with the increase in the number of obese children, the number of teenagers developing type 2 diabetes has increased dramatically.
Your chance of developing type 2 diabetes rises steeply with increased body fatness. (80% of type 2 diabetics are overweight or obese at time of diagnosis).
Weight management through diet and exercise can significantly delay/reduce the risk of developing type 2 diabetes. One study found that combining weight loss of 7 kilos or a stone, along with 150 minutes a week of physical activity, reduced the number of obese people developing type 2 diabetes by 58%.
For people who are already have diabetes, being overweight increases their chance of developing serious complications.
Even if you are happy with your weight, taking regular exercise will improve your health. If you are a diabetic or have a family history of diabetes it will be even more effective in protecting your health. (If you are a diabetic you should seek advice from your GP or diabetic specialist nurse, before starting a new exercise programme).
