Question

which plan is safe and includes all the necessary parts to completely address the issues involved with improving your body composition?
a. andy wants to increase his lean muscle mass. he is not worried about his bmi because it is in the normal range. he will lift weights five times a week at the maximum intensity possible.
b. mark wants to decrease his bmi, so he will exercise for 60 minutes five days a week. he will monitor his strength training using a workout log and plans to eat six, well - balanced, 300 - calorie meals a day.
c. lisa wants to increase her bmi, so she plans to go running for 60 minutes five days a week. she also plans to eat six, protein - rich meals a day that are about 300 calories each.
d. rachel wants to slim down for a big pool party that is coming up next weekend. she is going to exercise for 60 minutes a day. she also plans to reduce her caloric intake to 600 calories a day by eating diet bars.

Explanation:

• Option A: Only focuses on maximum intensity weightlifting without addressing nutrition, which is critical for lean muscle gain, and ignores potential overtraining risks.
• Option B: Combines regular exercise, strength training tracking, and balanced, controlled-calorie meals. This addresses both activity and nutrition safely for healthy body composition change (lowering BMI via fat loss while preserving muscle).
• Option C: Running (cardio) paired with high protein intake is not ideal for increasing BMI, as running burns significant calories and may not support healthy weight/muscle gain effectively.
• Option D: A 600-calorie daily intake is dangerously low, leading to muscle loss, nutrient deficiencies, and is an unsustainable, unsafe crash diet.
