If you are taking Semaglutide or Tirzepatide — or considering a GLP-1 weight loss programme — you have probably spent time watching the number on your scale. But that number tells you almost nothing useful.
A scale measures total weight. It cannot tell you whether you are losing fat, muscle, or water. It cannot tell you whether your visceral fat — the dangerous fat surrounding your organs — is decreasing. It cannot tell you whether your metabolism is slowing down as you lose weight.
The InBody 970S can tell you all of this. In 45 seconds.
At Sleep & Wellness Medical Associates in Princeton NJ, every GLP-1 weight loss patient begins with an InBody 970S scan — and repeats it at every session throughout their 12-week programme. Here is why that changes everything.
What Is an InBody Scan?
The InBody 970S is a medical-grade body composition analyser. It uses bioelectrical impedance analysis (BIA) — sending a safe, imperceptible electrical signal through your body via eight contact points on your hands and feet.
As the signal passes through different types of tissue, it encounters different levels of resistance. Muscle, fat, and water all conduct electricity differently. The device uses this information to calculate your body composition with a high degree of precision — taking 30 separate impedance measurements across six frequencies and five body segments.
The result is a detailed printout showing:
- Skeletal muscle mass — total and by body segment
- Body fat mass — total and by body segment
- Visceral fat level — the fat surrounding your organs
- Total body water — broken into intracellular and extracellular
- Basal metabolic rate — the calories your body burns at rest
- Lean body mass — segmental analysis across five areas
All of this, in approximately 45 seconds, with 99% result reproducibility.
Why Does This Matter for GLP-1 Weight Loss?
GLP-1 medications like Semaglutide (Wegovy, Ozempic) and Tirzepatide (Mounjaro, Zepbound) are highly effective at reducing body weight. Clinical trials consistently show 15–20% body weight reduction with sustained physician-supervised treatment.
But weight loss is not the same as fat loss. During any significant calorie deficit — including one induced by GLP-1 medications — the body can lose both fat and lean muscle mass.
Muscle loss is a serious concern for several reasons. It slows your metabolism, making long-term weight maintenance harder. It reduces functional strength and physical capacity. And it can create a body composition that looks similar on the scale but feels and performs very differently.
The InBody 970S makes the invisible visible. When Dr. Siddique reviews your scan results at each session, he can see exactly what has changed since your last visit — not just your total weight, but the ratio of fat to muscle, the distribution across your body segments, and whether your visceral fat is responding to treatment.
How InBody Scanning Changes Your Programme
At our Princeton NJ clinic, InBody 970S data directly informs three things:
1. GLP-1 Dosage Adjustments
If your scan shows rapid muscle loss alongside fat loss, Dr. Siddique can adjust your dosage, your nutrition guidance, or recommend complementary treatments to protect lean mass. If your fat loss is progressing well and muscle is being preserved, the current plan continues.
2. Nutrition Planning
Knowing your basal metabolic rate — the calories your body burns at rest — allows for nutrition guidance that is calibrated to your actual metabolism, not a generic formula based on height and weight.
3. Complementary Treatment Decisions
For patients who have achieved significant fat loss and notice skin laxity or residual areas of concern, InBody data helps determine whether and when body contouring treatments such as Morpheus8 or BodyTite would be appropriate.
InBody 970S vs a Regular Scale — the Difference in Practice
Consider two patients who have both lost 20 pounds over three months on Semaglutide.
Patient A’s InBody scan shows they have lost 18 pounds of fat and 2 pounds of muscle. Their visceral fat has decreased significantly. Their basal metabolic rate is stable. This is an excellent result.
Patient B’s scan shows they have lost 12 pounds of fat and 8 pounds of muscle. Their visceral fat has decreased modestly. Their basal metabolic rate has dropped noticeably. This result needs intervention — a dosage review, a nutrition adjustment, and possibly the addition of a muscle-preservation protocol.
Without the InBody 970S, both patients look identical on the scale. With it, their programmes can be managed completely differently.
What to Expect from Your InBody 970S Scan
The scan itself is simple. You remove your shoes and socks, stand on the device’s foot electrodes, and hold the hand electrodes at your sides. A mild electrical current — completely imperceptible — passes through your body. The device takes approximately 45 seconds to complete its 30 measurements.
You should avoid eating, drinking, or exercising for two to four hours before your scan for the most accurate results. Hydration levels affect BIA readings, so consistency in your pre-scan routine helps ensure your results are comparable over time.
Your results print immediately after the scan and are reviewed with you by Dr. Siddique at your appointment.
The InBody 970S at Sleep & Wellness Medical Associates Princeton NJ
The InBody 970S scan is included at every session throughout your 12-week weight loss programme at our clinic. It is not an add-on or an additional cost — it is the foundation of how we build and monitor every personalised programme.
We use it at your initial consultation to establish your baseline. We use it at every session to track your progress. And we use the data it provides to ensure that the weight you are losing is the weight you want to lose — fat, not muscle.
If you are considering a GLP-1 weight loss programme in Princeton NJ, or if you are already on Semaglutide or Tirzepatide and want more precise monitoring of your progress, we would be glad to speak with you.
