Charlene has a bmi of 29; therefore, she wants to change her body composition. which plan would be best for her? a. she should exercise 60 minutes a day, eat six small meals that equal less than 2,000 calories, and make sure to get plenty of rest. b.she should run 30 minutes a day, eat balanced meals that contain about 1,000 calories each, and sleep about six hours a night. c.she should lift weights 45 minutes a day, eat 4,000 calories a day, and sleep at least 10 hours a night. d.she should do cardiovascular exercises, eat six small meals that altogether equal 1,000 calories, and sleep about eight hours a night.

A. She should exercise 60 minutes a day, eat six small meals that equal less than 2,000 calories, and make sure to get plenty of rest. A healthy BMI for a woman is in the range of 18.5 to 24.9, so I assume that Charlene wants to lose weight while remaining healthy. No matter what the diet, or exercise plan is, the only way to lose weight is to expend more calories than you consume. Exercise helps increase your muscle tone and increase your calorie consumption at the same time. So let's look at the options and see what makes sense and what doesn't. A. She should exercise 60 minutes a day, eat six small meals that equal less than 2,000 calories, and make sure to get plenty of rest. * This looks like a reasonable plan. Exercise will increase her calorie consumption and keep her fit. It takes on average 2000 calories for a woman to maintain her weight, so taking less will cause her to lose weight. And the weight loss should be fairly modest per week. Overall, this looks like a good and healthy plan. So it's the correct choice. B. She should run 30 minutes a day, eat balanced meals that contain about 1,000 calories each, and sleep about six hours a night. * Assuming breakfast, lunch, and dinner, that's 3000 calories a day. Since 2000 calories a day is what the average woman takes to maintain her weight, Charlene will definitely change her body composition with this plan. But in the wrong direction. So this is a bad choice. C. She should lift weights 45 minutes a day, eat 4,000 calories a day, and sleep at least 10 hours a night. * 4000 calories a day is quite a bit and she wants to lose weight, not gain it. So this is definitely a wrong choice. D. She should do cardiovascular exercises, eat six small meals that altogether equal 1,000 calories, and sleep about eight hours a night. * This plan works to lose weight, but to lose a single pound, it takes a woman about 1500 calories. And since a maintenance diet is 2000 calories per day, she's losing 7000 calories per week, or almost 5 pounds per week. A healthy rate of weight loss is a more modest 1 to 2 pounds per week. This plan is too excessive and therefore wrong.
