Final answer:
To lose 1.5 lbs per week, a client must create a weekly caloric deficit of 5250 calories, or 750 calories per day, by either consuming fewer calories or increasing physical activity.
Step-by-step explanation:
To lose 1.5 lbs per week, a client needs to create a caloric deficit of 5250 calories per week (since losing 1 lb requires a deficit of 3500 calories). This equates to a daily caloric reduction of 750 calories (5250 calories divided by 7 days).
It's important to consider that the actual calories required can vary based on individual metabolic rates, activity levels, and body composition. Creating a calorie deficit can be achieved by either reducing the number of calories consumed or by increasing physical activity. It is recommended to approach weight loss by combining a reduced-calorie diet with an increase in exercise to promote health and sustainable weight loss.
