The goal of a weight-loss program should be a real change in body composition (fat loss), achieved through a sustained negative energy balance, not the meaningless initial water-weight drop.
Detail
A focus on weight loss is partially responsible for the proliferation of low-calorie diets. Clients assume that weight loss equals fat loss and so are pleased with the initial large weight loss achieved on most of these programs. It is important to teach clients that this initial weight loss is meaningless, since it is mostly water lost as glycogen stores are used for energy.
A real change in body composition signifying fat loss should be the goal of a weight-loss program. Fat is lost by creating a negative energy balance, where clients expend more energy than they consume. Instead of focusing on a quick fix that produces only short-term weight loss, a client must learn to cultivate eating and exercising habits that lead to slow but steady fat loss that can be maintained for a lifetime. Success should be measured not only in pounds but also in terms of lifelong behavior change.

- Fat is lost by creating a negative energy balance (expend > consume).
- Aim for slow, steady, maintainable fat loss.
- Measure success in lifelong behavior change, not only pounds.
