Metabolic Testing & Body Composition Analysis (BIA) in Princeton, NJ

If you’ve been “doing everything right” but still struggling to lose weight, your metabolism—not your motivation—may be the missing link. At Sleep & Wellness Medical Associates in Princeton, NJ, Dr. Mahmood Siddique provides detailed metabolic testing and bioimpedance (BIA) body composition analysis to measure what truly matters beneath the scale.

Root-Cause Metabolic Analysis by Dr. Siddique

Our testing goes far beyond weighing you.

It tells you:

  • How much fat vs. muscle your body holds
  • How well your metabolism is functioning
  • Whether you may have hormonal or metabolic imbalances
  • How efficiently your body responds to food, exercise, and GLP-1 medications
  • What’s preventing you from losing weight or keeping it off
  • With over 30 years of clinical expertise, Dr. Siddique blends modern metabolic medicine + functional, holistic insights to help you make sense of your body and finally move toward real, sustainable results.

BIA Body Composition Analysis

How the BIA Scan Works

Our professional bioimpedance scanner uses safe, low-frequency electrical signals to give a detailed picture of your metabolic health.

  • Fat mass
  • Muscle tissue
  • Bone density trends
  • Water distribution
  • Cell health
  • Metabolic function

The Test Is:

  • ✔ Fast (about 5 minutes)
  • ✔ Non-invasive
  • ✔ Completely painless
  • ✔ Performed fully in-house

Your results are reviewed directly with Dr. Siddique or a clinical specialist, so you clearly understand what your body needs next.

Why Metabolic Testing Matters for Real Weight Loss

Most weight loss plans guess. We measure.

These insights reveal why your body hasn’t been responding—and what needs to change.

Part of a Holistic Functional Medicine Approach

Dr. Siddique believes in addressing root causes, not symptoms

Your metabolic testing is combined with:

  • Body Fat Percentage — Learn whether you’re holding more fat than optimal.
  • Visceral Fat Levels — Deep abdominal fat linked to inflammation and hormonal imbalance.
  • Muscle Mass & Lean Tissue — Protects your metabolism and prevents weight regain.
  • Hydration & Water Balance — Essential for fat burning, energy, and hormone function.
  • Basal Metabolic Rate (BMR) — Your real calorie-burning speed at rest.
  • Metabolic Age — How your body performs vs. your actual age.

This gives a complete metabolic picture not just an isolated data point.
