It is a precision-driven lifestyle transformation built to improve healthspan, metabolic function, strength, and long-term resilience.
Why We Rely on Metrics
Most programs rely on subjective measurements like the number on a scale. While that observations can be helpful, it lacks the precision and reliability needed to guide long-term success. At Healthspan Longevity, we take a different approach. We use validated, objective diagnostics to measure what truly drives sustainable fat loss and health improvement. We begin with a detailed baseline assessment that includes comprehensive blood biomarker testing, a DEXA scan for full body composition and bone density, and a resting metabolic rate test. These tools provide a complete picture of your metabolic function, muscle-to-fat ratio, inflammation status, cardiovascular risk, hormonal balance, and caloric needs. Rather than making assumptions or general recommendations, we use these gold-standard tests to design a plan that fits your physiology exactly. And we don’t stop there. We repeat these assessments at regular intervals, so we can track how your body is responding and refine your strategy in real time. This level of insight allows us to focus on what truly matters: reducing visceral fat, preserving and building lean muscle, improving insulin sensitivity, and supporting long-term metabolic health. It is not just about how much weight you lose, it’s about changing the internal markers that reflect genuine, lasting health improvement. This is how we deliver better outcomes, not just temporary results.
What We Test and Why: Personalized Data to Drive Your Results
Fasting Insulin
This test measures how much insulin your body produces to keep blood sugar in check. High insulin even with normal glucose can signal insulin resistance, which makes fat loss more difficult and increases the risk of prediabetes. Lowering fasting insulin is one of the most important metabolic changes we track.
HbA1c (with eAG)
HbA1c shows your average blood sugar levels over the past 2–3 months. It helps identify early signs of glucose dysregulation and is a critical marker for long-term metabolic health. We use this alongside insulin to assess how your body handles carbohydrates and whether you’re at risk for insulin resistance.
Comprehensive Metabolic Panel (CMP)
This panel includes glucose, liver enzymes, kidney function, and electrolytes. It gives a snapshot of overall organ health and internal balance, which is important when adjusting nutrition or training.
Lipid Panel with Total Cholesterol/HDL Ratio
Assesses total cholesterol, LDL, HDL, and triglycerides. While not as specific as apolipoproteins, this provides a useful overview of cardiovascular health and can reflect dietary patterns.
Apolipoprotein Evaluation (ApoB, ApoA1, Lp[a])
These are the most advanced lipid markers available:
-
ApoB counts the number of atherogenic (plaque-building) particles key to assessing cardiovascular risk
-
ApoA1 reflects protective HDL function
-
Lp(a) identifies inherited cardiovascular risk that is not influenced by lifestyle. Important for long-term health planning.
High-Sensitivity CRP (hsCRP)
This is a sensitive marker of low-grade inflammation, which can interfere with weight loss, recovery, and metabolic health. Reducing hsCRP over time is a sign of systemic improvement and is influenced by better diet, sleep, and strength training.
Vitamin D (25-OH Total)
Supports insulin sensitivity, muscle strength, immune health, and mood. Deficiency is common and may limit fat loss, impair recovery, and increase inflammation. We optimize levels through nutrition and sun exposure, we only recommend supplementation when clinically necessary.
Vitamin B12
Critical for energy production, red blood cell formation, nerve function, and cognitive health. Low B12 can cause fatigue, slow metabolism, and impair focus. Especially important in clients with dietary restrictions or absorption issues.
TSH (Thyroid Stimulating Hormone)
Indicates how well the brain is signaling the thyroid. A basic screening tool for thyroid function, which affects metabolic rate and energy levels.
Free T4 and Free T3
-
Free T4 shows how much thyroid hormone your body produces.
-
Free T3 is the active form that regulates metabolism, energy, and fat burning.
Together with TSH, these provide a full view of thyroid health, which is essential when clients report fatigue, plateaued weight loss, or mood issues.
This panel gives us the most accurate and actionable data available to build your personalized plan. Each test is selected not just to screen for disease, but to fine-tune your nutrition, exercise, recovery, and longevity strategy.
DEXA Scan for Body Composition
Rather than focusing on weight alone, we use DEXA scanning to assess fat mass, lean muscle mass, bone density and visceral adiposity the deep abdominal fat most strongly linked to metabolic dysfunction and cardiovascular risk. DEXA is widely recognized in clinical research as the gold standard for body composition analysis because it offers a level of precision and repeatability that other methods simply cannot match.
Unlike a scale, which tells you nothing about the quality of your weight, DEXA gives us a clear breakdown of how much fat you carry, how much muscle you have, and where those tissues are distributed. This is essential for designing a program that supports fat loss while preserving or even increasing lean muscle. Losing weight on the scale could mean you are losing water, muscle, or fat but only DEXA can tell us exactly what is changing.
DEXA also provides a reliable measure of visceral fat, the type of fat stored around internal organs. High levels of visceral fat are associated with insulin resistance, chronic inflammation, and increased risk for heart disease and type 2 diabetes. By tracking changes in visceral adiposity, we can directly monitor improvements in metabolic health that go far beyond simple appearance or weight-based metrics.
Over time, repeated DEXA scans allow us to objectively track your progress and make informed adjustments to your exercise and nutrition strategy. This ensures that every step of your transformation is driven by real data, not guesswork or surface-level observations.
Multiple clinical trials confirm the superiority of DEXA over other body composition tools. For example, a randomized study published in the Journal of Clinical Densitometry found that DEXA allows for more accurate tracking of lean mass gain during resistance training, which is critical for long-term metabolic and functional health.
Resting Metabolic Rate (RMR) Testing
Understanding your Resting Metabolic Rate (RMR) gives us the foundation to determine how many calories your body naturally burns at rest each day. This is not a guess or a generic estimate based on age or height it is a measured value that reflects your true baseline metabolism.
Many people unintentionally eat too little or too much because they rely on online calculators or standardized calorie formulas that do not account for their individual metabolic rate. This can lead to stalled progress, fatigue, or even metabolic adaptation where the body downregulates energy expenditure.
By measuring RMR with a gold-standard indirect calorimetry device, we provide you with a precise caloric target that informs your nutrition strategy. This allows us to design a plan that aligns with your metabolic needs, avoids under fueling, and supports sustainable fat loss without compromising energy or lean muscle.
Studies have shown that using individualized RMR data improves the precision of dietary interventions and enhances weight loss outcomes. For example, a randomized controlled trial published in Obesity (2017) found that participants who used measured RMR to guide calorie intake achieved significantly greater fat loss compared to those using predictive equations. Another RCT in Nutrition Journal (2014) reported that tailoring energy prescriptions based on measured metabolic rate resulted in more consistent weight loss and reduced metabolic adaptation.
A 2020 study in Nutrition & Metabolism found that RMR-guided caloric planning led to significantly better fat loss and preserved lean mass compared to standardized calorie prescriptions. Knowing your baseline metabolism avoids the pitfall of under fueling, which can lead to muscle loss and a drop in energy expenditure.
At Healthspan Longevity, we use this level of precision to build programs that are not only more effective but also sustainable.
Personalized Nutrition
Our NASM Certified Nutritionist designs your personalized nutrition plan using the most complete picture of your physiology available. This includes your blood biomarkers, body composition from DEXA, and your unique caloric requirements from RMR testing. This means every recommendation you receive is tailored specifically to your metabolic profile, nutrient needs, and body composition goals.
We emphasize whole, fiber-rich, minimally processed foods, guided by the NOVA food classification system, which is widely used in nutritional science to distinguish between unprocessed, processed, and ultra-processed foods. A growing body of randomized controlled trials shows that diets higher in minimally processed, whole foods are associated with better blood sugar regulation, improved lipid profiles, reduced inflammation, and greater long-term weight stability. For example, a 2019 NIH-funded RCT published in Cell Metabolism found that participants who ate ultra-processed foods consumed over 500 more calories per day and gained significantly more weight than those who ate minimally processed foods, despite identical macronutrient composition.
We do not promote restriction or elimination diets that are difficult to maintain or nutritionally imbalanced. Instead, we guide you toward nutrient-dense meals that are satisfying, sustainable, and designed to optimize metabolic health. The goal is not to deprive, but to nourish supporting fat loss, muscle gain, hormone balance, and energy regulation through real food that fits your life.
Your plan will also evolve with your results. As your biomarkers, RMR, and body composition change over time, your nutrition guidance will adapt accordingly. This dynamic, personalized strategy supports consistency, progress, and long-term healthspan improvement.
Sleep Optimization
Sleep is a cornerstone of metabolic health and plays a critical role in fat regulation, hormone balance, cognitive performance, and recovery. At Healthspan Longevity, our sleep protocols are led by Dr. Chelsea Perry, Diplomate of the American Board of Dental Sleep Medicine, who brings advanced clinical expertise in identifying and addressing sleep-related breathing disorders, circadian rhythm disruption, and poor sleep quality.
Many individuals struggle with weight loss or metabolic dysfunction not because of what they eat or how they move, but because their sleep is fragmented, shallow, or misaligned with their biological clock. Sleep apnea, even in its mild form, is known to impair insulin sensitivity, elevate cortisol levels, and disrupt appetite-regulating hormones such as leptin and ghrelin. These changes can drive fat storage, increase cravings, and reduce energy levels making it harder to sustain a healthy routine.
Randomized controlled trials consistently support the role of sleep in metabolic health. For example, a study published in Annals of Internal Medicine found that participants restricted to 5.5 hours of sleep per night lost significantly more lean mass and retained more fat than those sleeping 8.5 hours, even when following the same calorie-restricted diet. Another RCT published in Diabetes Care showed that improving sleep duration and quality led to better insulin sensitivity and glucose tolerance in overweight individuals.
Our approach includes comprehensive screening for sleep apnea, individualized recommendations to enhance sleep architecture, and behavioral strategies to align your sleep with your circadian biology. This ensures your body can fully recover, regulate hormones effectively, and perform optimally both mentally and metabolically.
At Healthspan Longevity, we treat sleep not as an afterthought, but as a central pillar of your long-term success.
Exercise Guidance
While we strongly support structured movement and strength training, we do not present exercise as a primary method for weight loss. The scientific literature is clear: while exercise offers profound benefits for health, its effect on fat loss is often overstated, particularly when used in isolation. A landmark 2016 study published in Current Biology demonstrated that beyond a certain point, the human body compensates for increased physical activity by reducing energy expenditure in other physiological systems. This adaptive response limits the net calorie deficit and challenges the long-held belief that more movement always equals more weight loss.
At Healthspan Longevity, we use exercise not as a calorie-burning strategy, but as a tool for enhancing body composition, strength, resilience, and long-term metabolic function. Our movement plans are built around data from your DEXA scan and RMR test, allowing us to prioritize muscle maintenance and growth. Preserving lean mass is essential during fat loss and is one of the most predictive factors for long-term metabolic health.
Exercise also plays a critical role in regulating blood sugar, improving insulin sensitivity, and reducing inflammation all core elements of a successful healthspan-focused program. Beyond the physical, regular movement improves mood, reduces anxiety, enhances sleep quality, and supports cognitive function. These benefits are well documented in randomized controlled trials, including a 2021 meta-analysis in The Lancet Psychiatry which found that physical activity significantly reduces symptoms of depression and stress, both of which are often barriers to maintaining healthy habits.
Our programs integrate strength training, mobility work, and cardiovascular conditioning in a balanced, individualized manner. Each session is designed to complement your nutritional intake, recovery capacity, and health goals not to exhaust or punish the body for calories consumed. This shift in philosophy allows our clients to develop a positive, sustainable relationship with movement while achieving real physiological change.
At Healthspan Longevity, we position exercise as a foundational component of your vitality, not a weight-loss shortcut. The goal is not just to move more, but to move with purpose, supported by your data and aligned with your long-term healthspan.
