Quizplus · Accepted Answer

A reduction or energy expenditure of 3,500 calories (kcal) will result in a weight loss of 1 lb (0.45 kg). To lose 20 lb (9 kg), the client needs to reduce intake by a total of 70,000 kcal (3500 kcal x 20 lb [9 kg] = 70,000 kcal). Over a period of 16 weeks, this would require a daily reduction of: 625 kcal (70,000 kcal / [16 weeks x 7 days] = 625 kcal/day) Adding an exercise regimen to the client's daily routine would facilitate additional weight loss and/or reduce the need for severe caloric restriction. (Option A) Reducing intake by 450 kcal/day over 16 weeks would result in a weight loss of 14.5 lb (6.5 kg). (Option C) Reducing intake by 860 kcal/day over 16 weeks would result in a weight loss of 27.5 lb (12.4 kg). (Option D) Reducing intake by 1000 kcal/day over 16 weeks would result in a weight loss of 32 lb (14.5 kg). Educational objective: A reduction or energy expenditure of 3500 calories (kcal) will result in a weight loss of 1 lb.
