Body Composition & Resting Metabolic Rate Testing

Understanding your body composition and metabolism helps us tailor a plan you can sustain. We use testing to set protein targets, guide calorie ranges, and shape training—so you protect lean mass and feel your best.

Key Takeaways

• Testing turns guesses into personalized targets (protein, calorie range, training focus).
• We aim to protect lean mass—especially during weight loss and GLP-1 treatment.
• Most people re-test every 8–12 weeks to track trends, not chase one number.

What We Measure

• Body Composition (estimated body fat %, lean mass, total body water)
• Resting Metabolic Rate (RMR) — your baseline energy needs at rest
• Waist circumference & vitals, as indicated

How We Measure (Methods)

• Body Composition: We use a state of the art Inbody scan, which provides a noninvasive measurement of muscle mass, body fat and water content. We avoid Bioelectrical impedance analysis (BIA) for some implanted electronic devices—tell your clinician.
• RMR: Our In Body scan calculates resting metabolic rate.

Preparation (Maximize Accuracy)

• Be well-hydrated and empty your bladder before for body composition testing.
• Avoid strenuous exercise, large meals, alcohol, and sauna within several hours.
• For RMR, arrive rested; avoid caffeine/nicotine for several hours; limit talking/movement before thetest.
• Tell us about implanted devices

When to Test & Re-Test

• Baseline: during your initial evaluation
• Follow-up: body composition and RMR every 8–12 weeks.

How Results Shape Your Plan

• Protein: Set daily targets to support muscle and satiety (g/kg and per-meal goals).
• Calories: Use RMR + activity to define a flexible range, not a rigid number.
• Training: Balance progressive resistance (maintain/build lean mass) with aerobic work forcardiometabolic health.
• Medication alignment: If you’re using GLP-1s or other therapies, we tune protein, hydration, mealtiming, and training to protect lean mass and tolerance.

We’ll review your report together and translate numbers into simple daily actions for meals, movement,and sleep.

Case Snapshots

• Plateau Buster: After 10 lbs lost, Sarah’s RMR + training review showed under-recovery. We added 2–3 full-body strength days, bumped protein, and anchored sleep—progress resumed.
• GLP-1 Lean-Mass Guard: Mike on a GLP-1 added two protein-forward meals and brief resistance circuits; lean mass stabilized while body fat fell.

Question

Is testing safe with a pacemaker or implant?

+
+
Answer

We avoid BIA with certain implanted devices. Tell your clinician; we’ll use an alternative method.

Question

Do I need to fast?

+
+
Answer

For RMR, avoid caffeine; for body composition, avoid large meals 3-4 hours beforetesting. We’ll give specific instructions.

Question

Will this tell me exactly how many calories to eat?

+
+
Answer

All calories are not the same. We focus more on healthy nutrition that is satisfying and meets your metabolic needs for overall health.

Question

What if my results seem low/high?

+
+
Answer

Hydration, sleep, and recent activity can influence readings. That’s why prep matters—and why we look at trends over time.
