A client is attempting to lose 10 pounds. In order to lose 1.5 pounds per week, she will have to reduce her caloric intake per day by how many calories?

A deficit of 350 kcal/day equals only 2,450 kcal/week, which would result in a loss of approximately 0.7 pounds per week, not 1.5.

A deficit of 500 kcal/day equals 3,500 kcal/week, which targets exactly 1 pound per week, not 1.5 pounds.

One pound of fat is equivalent to approximately 3,500 kcal. To lose 1.5 pounds per week, the total weekly deficit must be 1.5 x 3,500 = 5,250 kcal. Dividing by 7 days yields a required daily deficit of 750 kcal.

A deficit of 1,000 kcal/day equals 7,000 kcal/week, which targets 2 pounds per week, exceeding the 1.5-pound goal.
