A Patient Asks a Nurse Which Weight-Loss Diet Is Most

A patient asks a nurse which weight-loss diet is most effective. Which response by the nurse is appropriate?

A) "Low-fat diets are best for weight loss, because fat has a higher concentration of calories than proteins and carbohydrates."
B) "Most diets don't work very well for long-term maintenance, so you should ask your provider about medications to lose weight."
C) "You should be able to lose 30 to 40 pounds in the first 6 months of an effective weight-loss diet."
D) "You should select a diet that you are more likely to adhere to for a prolonged period."
