Body composition testing gives you a starting map: how much of your weight is muscle, fat, and water, and how that changes over time. At Elysian Institute in Bigfork, MT, InBody testing is available as part of our weight-loss testing package for clients who want that level of detail alongside their plan.

What Does the InBody Data Actually Show?
An InBody scan breaks your weight into segments instead of one number on a scale, and those segments can look very different from person to person.
Muscle, Fat, and Water by the Numbers
It reports muscle mass by limb, visceral fat, total body water, and a basal metabolic rate estimate, all in about five minutes. Two clients who weigh the same can have very different results underneath, and the scan helps provide additional context about their body composition. Clients at our biohacking longevity clinic in Bigfork, MT, often note this segment-by-segment detail as the part that surprises them most.
Why the Explanation Matters as Much as the Scan
For clients enrolled in our weight-loss testing package, results are reviewed with them either by Katelyn Mahlum, APRN, FNP-C, or by our fitness director, Ashton Freeman, rather than handed over as a printout with no context. Looking at muscle mass, body fat, and hydration together helps clients understand what their numbers mean. A 2024 study found that the InBody 770 multi-frequency BIA system achieved an intraclass correlation coefficient (ICC) of 0.999 or higher for whole-body water and mass measurements across five laboratory visits, demonstrating highly consistent repeat scans under controlled conditions. To support consistent measurements, we ask clients to follow simple pre-scan guidelines, including avoiding strenuous exercise and fasting beforehand.
How Does Retesting Help Track Progress Over Time?
A single scan is a snapshot; the pattern across several visits shows how those numbers move.
Retesting on a Few-Week Cycle
Clients in our weight-loss testing package can retest every few weeks to track how their body-composition measurements change over time. For a broader look at how these pieces connect for Bigfork clients, our post on professional performance wellness center services in Montana covers how IV and IM support pair with testing. Results are shared with clients for their own awareness and are not used to change their treatment protocol.

How This Differs From a Standard Membership
This is also where our health optimization clinic model differs from a typical Bigfork gym membership: recovery modalities, IV and IM support, and testing are each available on their own, so clients can choose the combination that fits their goals instead of a fixed package everyone receives. Since IV and IM support are medical therapies, adding either to a plan means a short intake with our nurse practitioner first; the InBody scan itself doesn’t require one. Clients in the weight-loss testing package who retest regularly often say it helps them stay motivated, because they can see the numbers move.
For clients in our weight-loss testing package, retesting provides a way to track changes in body-composition measurements over time. A single scan can establish a baseline, while a second scan a few weeks later can provide a clearer picture of how those measurements have changed. The results are shared with clients for their own awareness and are not used to modify their treatment protocol.
