Nearly 44% of adults in Cardiff aged 16-64 have a healthy weight, above the Wales average. Although Cardiff is doing relatively well in this area this leaves the majority of people overweight, obese or underweight. Obesity decreases life expectancy by up to nine years and causes insulin insensitivity, which is an important risk factor in chronic diseases such as diabetes, heart disease, high blood pressure and stroke. Being underweight can compromise your immune system and cause fragile bones in later life.
