Mary wishes to lose 5 pounds before her vacation in approximately 5 weeks. Her average consumption is 2100 kcal per day. Assuming her physical activity levels remain unchanged, she should reduce her energy intake to kcal per day.

1600 kcal/day.

Explanation:

3500 kcal = 1lb

To lose 1lb per week, you'd need to cut 500 kcal per day from your current kcal intake.

For mary, 2100kcal - 500kcal = 1600kcal per day.

At this rate, she would lose 1lb per week - if she wants to lose 5 pounds before her vacation 5 weeks from now, this would be the correct caloric intake.

i think it's the first one because doctors aren't the ones who get rid of the old needles. most of them time it's not even doctors who give you shots, it's nurses.
