Question

45 year old

Weight 202 lb

Skinfold analysis indicates 24% of his weight is fat, if he wants to decrease his body fat to 17% what is his target body weight, assuming he maintains the same lean body mass?

Answer 1

To determine the target body weight, we need to calculate the current fat mass and lean body mass. The target body weight is then found using the equation: Target Body Weight = Current Lean Body Mass / (1 - Desired Body Fat Percentage / 100).

Step-by-step explanation:

To calculate the target body weight, we need to determine the current fat mass and lean body mass.

Given that the weight is 202 lb and the body fat percentage is 24%, the current fat mass can be calculated as follows:

Current Fat Mass = Weight * (Body Fat Percentage / 100) = 202 lb * (24 / 100) = 48.48 lb

The current lean body mass can be calculated as the difference between the weight and the current fat mass:

Current Lean Body Mass = Weight - Current Fat Mass = 202 lb - 48.48 lb = 153.52 lb

Now, to find the target body weight with a desired body fat percentage of 17% while maintaining the same lean body mass, we can use the following equation:

Target Body Weight = Current Lean Body Mass / (1 - Desired Body Fat Percentage / 100) = 153.52 lb / (1 - 17 / 100) = 185.57 lb

Therefore, the target body weight is approximately 185.57 lb.
