Any advice that we give is based on the information you have given us. You should always follow advice you have been given by a health professional.
While you don’t currently have a long term health problem it is important that you take action to reduce your risk of future problems. As you have said you have lost weight over the last year it looks like you have already started.
You have said that you haven’t really tried to lose weight before – if you have not been trying to lose weight it is important for you to speak to your GP. You may find that you need more specialist help to lose weight.
