In reality, it is actually different for every individual and is dependent on health, body fat content and distribution, musculature, age, activity, metabolism, and a host of other factors that are not simple to measure accurately. For these reasons, you and your physician or dietitian must decide what your ideal weight should be. You probably have an idea what that weight is. Start conservatively. And if you reach your target weight and still feel you need to trim off additional weight, you always have option to set a new target goal."
