Weight reduction is an issue that many people struggle with worldwide. Because of the influence of media people have been made to believe that there is an ideal weight. This is not strictly true. What is more important is to be healthy. A medical person can check your weight compared to your height and then tell you if you need to lose or gain weight or remain the same. This measurement is called a body mass index.
If after measurement of your BMI you are either overweight or even obese, your health care provider can come u with a routine that can help you lose weight in health way. It is important to note that weight loss is not just the physical but there is a large mental component that helps you to maintain the weight loss. This includes things like diet change, lifestyle change exercise etc.
Therefore in answer to your question, before you embark on weight loss please get your BMI checked so that you can even have a target weight that you are aiming at instead of just blanket weight loss.
