Every visit, without exception
Four things that are true of every visit
Care by an OB/GYN
Every procedure at Oshun is reviewed and led by a board-certified Obstetrician and Gynaecologist. Dr. Rockhead is a physician first — the same one who treats women's health on the other side of his practice.
30 years caring for women
Three decades as a practicing OB/GYN at Amadeo Medical Group, the parent clinical practice. Every Metabolic Testing plan is reviewed by a physician who has cared for women through pregnancy, surgery, perimenopause, and post-natal recovery.
Written plan first
Every Metabolic Testing patient leaves consultation with a written plan: areas, technique, timing, recovery, cost. Returning patients refine the same plan rather than starting from scratch every visit.
Conservative, considered
Oshun's approach favours conservative, considered care over aggressive intervention. Decisions are made in conversation with you, options are presented in plain language, and consent is informed at every step.
Treatment Details
Every fact about your first visit, in plain language.
Most first-time patients arrive with the same set of unspoken questions. They are answered below in the order most people think them — from "how much will I need" to "what if I'm pregnant."

01Metabolic Testing 101
The procedure itself.
Metabolic testing measures resting metabolic rate (RMR) by indirect calorimetry and body composition by bioelectrical impedance (BIA) or DEXA. Used to calibrate nutrition planning and track changes over time.
How long it's been around
Indirect calorimetry has been the clinical gold standard for RMR since the early 20th century.
What we treat with it
Workup of weight-management plateaus, assessment of caloric needs for nutrition planning, baseline in medical weight loss programs, body-composition monitoring.
The honest version
Why metabolic testing sometimes disappoints.
Metabolic testing disappoints when results aren't used to inform planning, when results are interpreted in isolation, or when patients expect a hidden "slow metabolism".
Most people's RMR is within normal range. Patients hoping the test will reveal a clinically slow metabolism are usually disappointed — weight resistance is more often about behavioural patterns, hormonal context, and muscle-mass loss.
Where metabolic testing genuinely helps is in calibrating caloric targets. Knowing your actual RMR gives a starting point better than guessing.
At Oshun, we don't run that model. Metabolic Testing here is physician-led from consultation through follow-up, with a written plan in your hands and a follow-up visit on the calendar before you leave.
02Medical Leadership
The same physician, from first question to final follow-up.
Metabolic testing at Oshun is interpreted by Dr. Rockhead in context with your medical history, weight history, and hormonal status. Clinical interpretation makes the number actionable.

Dr. Charles Rockhead
Medical Director · Board-Certified OB/GYN · 30+ years of practice
Dr. Charles Rockhead is a board-certified Obstetrician and Gynaecologist with more than thirty years of practice in Kingston. He is the Medical Director of Oshun Cosmetic Services and the founding physician of Amadeo Medical Group, the parent clinical practice.
A Metabolic Testing visit at Oshun follows a clear sequence — from consultation through the procedure itself through follow-up. Here is what happens, step by step.
i.
Consultation
Before any Metabolic Testing is scheduled, you meet Dr. Rockhead in person at 9 Devon Road. He reviews your medical history, examines you as appropriate, and explains the options — including the option not to proceed. You leave with a clear written plan and a quote.
ii.
Preparation
Fasting 4–5 hours before RMR. No exercise 12 hours. No caffeine the morning of. Comfortable clothing without metal underwiring for BIA.
iii.
The metabolic test
After fasting and resting requirements are confirmed, you lie comfortably while breathing into a mouthpiece for 15–20 minutes; the device measures oxygen consumption to calculate RMR. BIA body composition follows. Results discussed before you leave.
iv.
Recovery & follow-up
Resume normal activities. Use the report as a baseline for nutrition and training planning. Repeat every 3–6 months when tracking change.
How much you'll need
Single test, repeated every 3–6 months when tracking change.
Will it hurt?
Non-invasive. RMR requires lying still and breathing into a mouthpiece for 15–20 minutes.
How long the visit takes
30–60 minutes.
Time off after
No downtime.
04Results & aftercare
Recovery and follow-up.
Same-day results with written interpretation discussed at the visit.

05Is Metabolic Testing right for you
Who gets the most out of Metabolic Testing at Oshun.
Who should not have Metabolic Testing
Pregnancy (BIA generally avoided), implanted electronic devices (BIA), inability to breathe through a mouthpiece (RMR).

Weight loss plateau
Workup of weight-loss plateau
