Weight Reduction Formula

There’s a massive campaign to encourage weight loss in obese individuals. Health and nutrition advocates often encourage people to change diets or exersize in order to lose weight. This has led to a variety of unhealthy dieting, fasting and weight loss surgery. None of this has proven completely effective. In fact, 90% of people who diet wind up back at the weight they started, sometimes heavier. However, correlations between premature death and many health-related diseases have been found among obese individuals (although many argue that there are just as many health-related problems among those with alledgedly ideal weights, and that nutritionists do not appropriately consider the individuals lifestyle and exersize habits before pointing the finger at overweight). What do you think?
Maybe my question is unclear: What I mean is, why do we advocate WEIGHT LOSS per se, as opposed to simply healthy living/eating? Do you think a person who is physically active and eats healthily is still at risk if they are not losing weight?
