What formula is used to calculate Target Body Weight (TBW)?

The target body weight (TBW) is calculated using the formula TBW = FFM / (1 - (desired BF%/100)), where FFM stands for fat-free mass. This formula is grounded in the principle of understanding the relationship between total body weight, fat mass, and fat-free mass.

To determine TBW, it is essential to know the individual's fat-free mass and the desired body fat percentage. The desired body fat percentage (BF%) is converted to a decimal by dividing it by 100, and then this value is subtracted from one to yield the proportion of weight that will be composed of fat-free mass in the target body weight. By dividing the fat-free mass (which remains constant) by this proportion, we can accurately estimate the total target body weight while achieving the desired body fat percentage.

Using this formula ensures that the calculation reflects the individual's goal in terms of body composition, guiding effective weight management strategies. This method is particularly useful as it accounts for the individual's lean body mass, providing a more tailored target relevant to their specific health and fitness objectives.
