Maintaining a healthy weight isn’t just good for your physical health. It plays a vital part in your mental well-being too. If you’re overweight, you’re more likely to suffer medical conditions such as Coronary heart disease, Type 2 diabetes, and certain cancers, including breast and bowel. You are also more likely to suffer a stroke and a heart attack than others of the same age. There is strong evidence that weight issues are also linked to depression.
