- Calculate the daily calories needed for a 150-pound person if s/he sleeps 8 hours, sits 10 hours, stands 3 hours, walks 2 hours, and swims 1 hour in each 24-hour period.A 25 year old male athlete who weighs 75 kg and is 178 cm tall consumes 3200 kcal's/day. His daily physical activity level would be considered heavy. Based on this information, what is his predicted daily energy expenditure? With his current diet and activity level, is he in positive, negative, or neutral energy balance?The information of Subject A is as follows Gender Age Height WeightFemale 28 160cm 153lb (a) Define basal metabolism. Estimate the Basal Metabolic Rate (BMR) of Subject A (state how you estimate it). (b) Calculate the Body mass index (BMI) of Subject A. What is the weight classification of Subject A? Based on the BMI calculated, give detailed recommendations for this subject to become healthier and explain. (c) Subject A chose to have stir-fried beef & spinach for her lunch to increase the iron intake and thus lower the risk of iron deficiency. Suggest why she will choose this dish? (Support the answer with data). Explain if there is any difference between the iron source in beef and spinach.
- Calculate the Basal Metabolic Rate (BMR) for a 29 year old female who weighs 57 Kg, 167 cm tall and leads a sedentary lifestyleA 45 year old Jenny wanted to determine if she is taking enough food to gain weight. She currently weighs 55kg and takes in 2,000kcal per day. The following are her activities: (1) sleep for 7 hours (2) running for 2 hours with an estimated energy expenditure of 4.5kcal/min (3) working for 10 hours with an average energy expenditure of 3.5kcal/min, and (4) rest for the remaining time with an estimated time of 1.5kcal/min.Briefly describe weight/body mass gain and weight/body mass loss in terms of energy balance.
- MN is a 20-year-old male. He consumes an average of 11 g of fiber daily. Calculate the percentage of RDA/AI for fiber provided in his typical diet.A 38-year-old female weighing 170lbs with a height of 5’3” and has a light activity consumes 2, 500 kcal per day. Compute his caloric requirement using IBW. Is she eating enough for her caloric needs?Some causes of weight gain in adults include slow metabolism, increased food intake or reduced activity. Discuss two factors that may contribute to each cause.
- Define basal metabolic rate and discuss factors that can decrease or increase it.CW is a 22-year-old female. She consumes an average of 750 mg/d calcium and 9 micrograms/day vitamin D daily as part of her typical diet. Calculate the percentage of RDA/AI for calcium and vitamin D provided in her typical diet.Endurance athletes sometimes follow the exercise-and-diet plan described here: 7 days before an event, do exhaustive exercises so as to all but deplete glycogen stores. For the next 2 to 3 days, consume few carbohydrates and do moderate- to low- intensity exercises. Finally, 3 to 4 days before the event, consume a diet rich in carbohydrates. Explain the benefits of this regime.
