  • What is the InBody Challenge?

    The InBody Challenge scoring system is designed to provide participants with an easy way of tracking changes in body composition over time and reward them for making positive changes.

    Rather than focusing solely on weight loss, the goal of this competition system is to reward individuals who improve their overall body composition by increasing their muscle mass and/or losing overall fat mass. The scoring system is devised to make the competition fair to all participants. By judging the amount of change (in lean or fat) in comparison to their starting level, this will allow all participants to be judged in a consistent fashion. It also allows people with dramatically different body compositions to participate and compete against each other in the same competition.

    To illustrate this, take a look at the two example subjects below. Subject A represents a lean, athletic body type whereas Subject B represents a heavyset, sedentary adult male.

    Because Subject B has more starting Fat Mass than Subject A, it may be much easier for Subject B to lose body weight, which would put Subject A at a distinct disadvantage in a more straightforward weight loss competition. To compensate for any starting advantages, the InBody Challenge will choose a winner based on how significant the changes in body composition are for that specific individual and NOT take into account pure weight loss. For example, if both Subjects A and B were to lose 10 pounds of body fat, they would effectively be tied in terms of pounds of weight loss. However, by taking into account the percentage of change relative to their starting points, Subject A made a much more significant change in his body composition. See below:

    Subject A would be rewarded for creating a greater change in body fat (40% vs 15.4%), even though the total loss in body fat was the same for both. However, weight loss is affected by changes in both body fat and Lean Body Mass/muscle. How do changes in muscle affect the results of the competition? Let’s assume Subject A focused on building muscle and gained 5lbs of LBM (Lean Body Mass), while Subject B's priority was losing as much body weight as possible and unintentionally lost 5lbs of LBM:
    Because Subject A gained 5 pounds of LBM (positive change), this would offset the 10 pounds of fat loss for an overall net weight loss of 5 pounds. On the other hand, Subject B lost 5 pounds of LBM (negative change), adding to the 10 pounds of fat loss for a net weight loss of 15 pounds. To determine a winner, the Excel file will add the percentage of LBM change with the percentage of Fat Mass change to determine overall direction and amount of overall net change:
    Despite only losing 5 pounds of body weight vs. Subject B’s 15 pounds of weight loss, Subject A would still win by a wide margin for showing the most positive change in overall body composition. The actual amount of change in overall weight is not important. What is important is the amount of change in body composition relative to an individual's starting point.

    The formulas used for the InBody Challenge will be determined by using the Lean to Fat Ratio
    1. (LBM beginning – LBM End) / Beginning LBM
    2. (Fat End – Fat Beginning) / Beginning Fat

    *You may download the InBody Challenge Calculator under the Resources tab for a copy of the Calculator. . Note: not all circumstances can be automatically calculated.
    *Change in Body Weight is not considered for this competition

By joining this challenge, you agree to compete and be judged by the Lean to Fat Ratio, regardless of your complaints or opinions about the “unfairness” of any participant’s gender, age, body type or physical condition. The purpose of this event is to encourage participants to maintain good mental and physical health and is NOT a gambling event.

    By VOLUNTARILY signing up for the InBody Challenge, you certify that you are physically fit and have not been advised to not participate by a qualified medical professional.
