Question

  Pete's doctor has advised him to change his diet in order to lose 15 pounds at a rate of about 1/2 pound a week. To accomplish the weight loss, Pete must 
    A. eat slowly and skip at least one meal per day.B. eat snacks whenever he's hungry, rather than three full meals per day.C. decrease his calorie intake by about 500 calories per week.D. decrease his calorie intake by 250 calories a day. 

Answer 1

I think it might be C because a 3500 calories is one pound so if he wants to lose 15 pounds half of 3500 is 1750 so if he'd be in a diet of 500 calories intake a day that would accomplish his task or even make it expanded and lose even more weight depending on what he eats.
