Professional Metabolic & Longevity Testing in Central Alabama
You can’t build an effective wellness plan on assumptions. That’s why every LetsLose wellness journey starts with measurable data about how your body is functioning today.
Our in-clinic metabolic and longevity testing gives you and your health coach a clear, accurate picture of your metabolism, your body composition, and the markers that matter most for long-term health. It replaces guesswork and generic starting points with a baseline you can build a plan around.
Metabolic & Longevity Testing FAQs
Metabolic testing measures how your body uses energy at rest and during activity. At LetsLose, we use tools like PNOĒ breath analysis and InBody body composition scans to get a detailed, accurate picture of your metabolism, rather than relying on generic formulas based on age, height, and weight alone.
A PNOĒ test is a breath analysis that measures your resting metabolic rate, VO2 max, and how efficiently your body converts oxygen into energy. It provides one of the most accurate pictures available of how your metabolism functions, information that generic calculators simply cannot capture.
An InBody scan measures your body composition in detail, including muscle mass, fat mass, water levels, and visceral fat. Unlike a standard scale, it shows you what your weight is actually made of, which is essential information for building an effective wellness or weight loss plan.
Metabolic age compares how efficiently your body functions to typical results for your age group. A metabolic age higher than your actual age can be a sign that your metabolism needs support, while a lower metabolic age often reflects strong overall health. It’s one of the clearest, most motivating indicators we can offer patients.
Most patients are asked to avoid eating, intense exercise, and caffeine for a few hours before testing to ensure accurate results. Our team will walk you through any specific preparation needed based on which tests are part of your visit.
