Metabolic Testing in Lansing, MI
Health Built on Real Numbers
Metabolic health is the operating system underneath energy, weight, training, and recovery — and it can be measured. Serving Okemos, East Lansing, and Lansing, MI.
Schedule an AppointmentMetabolic functioning is the clinical focus area Dr. Janet Eng uses for everything operating below the visible surface of health — how your body produces energy, burns fuel at rest, responds to exertion, and stores what it does not use. Metabolic testing in Lansing, MI lives inside this focus area as the measurement piece: a structured way to get an actual resting metabolic rate in Okemos or a body composition snapshot, rather than reasoning from how clothes fit.
Dr. Eng approaches the work as data, not vibe. She is a board-certified emergency physician with thirty-plus years of clinical experience, fellowship-trained in medical toxicology, with continued training through the University of South Florida Morsani Personalized Medicine Course, A4M, AMMG, IFM, Frequency Specific Microcurrent, and My Injection Training, and currently participating in the AMSKU Ultrasound Fellowship. Patients arrive with questions about fatigue, weight that will not move, athletic plateaus, or longevity goals — and metabolic measurements give her something concrete to anchor the rest of the work to.

How We Measure Metabolic Health
Each measurement gives Dr. Eng an objective number to anchor your plan to — rather than reasoning from how clothes fit or how you feel on a given day.
Resting Metabolic Rate Testing
A direct measurement of how many calories your body burns at rest — the baseline number most nutrition and weight plans are missing.
Body Composition Testing
Clinical-grade measurement of fat mass, lean muscle, and bone — an objective baseline that makes every plan trackable.
Neuronova
Vibration-based neuromodulation — an 80 Hz pulse up the spine designed to support nervous-system regulation, focus, and calm.
How Care Works Here
Most plans here start with a question, not a procedure. The measurements feed back into calorie targets for nutritional changes, training zones for any aerobic work Dr. Eng prescribes, and follow-up tracking that revisits the same markers months later. Patients pursuing a resting metabolic rate session in Okemos typically arrive as part of a longevity plan, a SuperHuman Protocol cycle, or a focused effort to break a weight plateau. Where the numbers land determines what changes next — the data shapes the plan, the plan does not pretend to know what the data has not measured.
Questions About Metabolic Functioning
It is the clinical focus area that covers how your body produces and uses energy — across rest, exertion, recovery, and storage. Practically, it sits underneath the questions patients actually arrive with: why am I tired, why will this weight not move, why has my training plateaued, how is my long-term trajectory looking. The category is broader than any single test.
Feeling is real but slow and reactive. Metabolic measurements give Dr. Eng something to anchor decisions against — an actual resting calorie burn rather than an online calculator, an actual body composition rather than a scale reading. Without that anchor, plans tend to drift on inference.
Three patient profiles benefit most. Adults pursuing longevity who want a structured starting line. Athletes whose subjective effort no longer matches their results. And patients tracking metabolic health Lansing-area providers have not yet measured directly — where the numbers often surface the bottleneck the rest of a plan was missing.
Dr. Eng connects the numbers to the actual work — training intensities, nutritional targets, recovery cadence, supplementation choices. The data is a starting point for decisions across the rest of a functional medicine plan, not a one-time report. It also gives follow-up visits a way to measure whether the plan is doing what it was designed to do.
