You wouldn't expect your car to run properly unless you maintained it the right way. It's not something you pay attention to just once a year, but if you regularly put the right kind of fuel in it, drive it correctly, keep it clean and get on top on any small problems straightaway, then it's going to run successfully.
It's the same with maintaining a healthy weight. You need to make the change from a dieting mindset - a panic reaction leading to short-term, often drastic, and usually unsuccessful action - to a weight maintenance mindset. This is a proactive, long term strategy, where you need to actively work day-to-day to keep yourself within your healthy weight range. You look after your car to ensure it doesn't break down - do the same for yourself.
Before starting any weight loss or exercise plan you must consult a medical professional.
