HFW is built for long-term metabolic optimization.
Most patients work with us through a structured longevity membership model that includes:
There’s a reason your body isn’t responding. Stop guessing and find out what it is.
You want to know why, and a plan that fits your biology instead of a generic diet.
When a GLP-1 or another metabolic therapy is clinically appropriate, it is one part of a wider strategy. Appetite suppression on its own tends to cost muscle and leaves nothing in place for afterward. HFW pairs the medication with a protein target, resistance training, body composition tracking, metabolic monitoring, coaching, and a maintenance plan that is decided before you start, so what happens when the medication stops is part of the plan, not an afterthought.
Medication access is not guaranteed. Whether any therapy is appropriate for you remains a clinical decision, subject to review and to the requirements that apply where you live.

No waiting rooms, no referrals, and no "come back in six months."
A free telehealth call with an advanced care clinician to review your symptoms, goals, health history, and prior weight-loss efforts, and to decide whether HFW is the right fit and what to test first.
Testing establishes where you actually are: fasting insulin and glucose, HbA1c and lipids, a full thyroid panel, hormone patterns, inflammation, nutrient status, and body composition, selected because the result would change the plan. An advanced care clinician interprets it alongside your symptoms and goals and builds a prioritized plan. See the tests →
The contributors your results point to are addressed first or alongside, in a deliberate order. When medication is clinically appropriate, it is selected for your response and your labs and adjusted through monitoring, not left on autopilot.
Progress is measured in body composition, strength, and metabolic markers, not weight alone. Members retest with TruHealth each quarter with a scheduled clinician review, so the plan keeps following your results into maintenance. See membership →
Progress is read across all of these, reviewed with you as the plan progresses.
A full thyroid panel means TSH, free T3, free T4, reverse T3, and thyroid antibodies, not TSH alone.

Where medication fits
When a GLP-1 or another metabolic therapy is clinically appropriate, it is one part of a wider strategy. On its own, appetite suppression tends to cost you muscle and leaves nothing in place for afterwards. These are the things HFW works on alongside it.
Protein and nutrition quality
Appetite suppression without adequate protein is how people lose the wrong kind of weight.
Resistance training
Muscle is metabolically active tissue. Protecting it is part of the plan, not an afterthought.
Lean mass and body composition
We track what the weight is made of, not only what the scale says.
Metabolic monitoring
Glucose, insulin, lipids, liver and thyroid markers, reviewed as the plan progresses.
Accountability
Habit and nutrition coaching, because knowing what to do and doing it are different problems.
Maintenance and discontinuation
A plan for what happens if and when the medication stops. Decided in advance, not improvised later.
Medication access is not guaranteed. Whether any therapy is appropriate for you remains a clinical decision, subject to review and to the requirements that apply where you live.
What sets HFW weight loss care apart
Body composition, not just body weight
The scale cannot tell you whether you are losing fat or losing muscle. HFW tracks body composition so your plan protects lean mass and strength while fat comes down.
Personalized dosing
When medication is part of the plan, the dose is not one-size-fits-all. It is selected for your response, your goals, and your labs, then adjusted through monitoring rather than left on autopilot.
Accountability and habit coaching
A plan only works if it gets implemented. Structured coaching supports habits, nutrition, and training between visits, with regular check-ins so progress does not depend on motivation alone.
Bone density and strength as you age
Poorly managed weight loss can cost bone and muscle, and that matters more with every decade. Your plan is built to protect both, not just to lower a number.
It all starts with testing
Before any plan, HFW establishes a baseline: metabolic markers, body composition, and the context that determines what your plan should actually contain. Testing before guessing.
We do not just help you lose weight. We find out why your body is holding onto it.

It’s been a blessing working with Dr. Landi and his entire team! After getting my test results, Dr. Landi walked me through a number of helpful steps to restore my health. He is very knowledgeable and uses an in-depth functional medicine approach in addressing health concerns. Bernadette is also very kind and thoughtful and I enjoy the interpersonal connection I have built with all of them.

I have been working with Dr Landi for several months now. He is extremely knowledgeable, attentive and responsive. He actually listens which is rare in medicine these days. I’m excited to see what the results are from my protocol in a couple of months. Highly recommend his practice if you’re looking into functional medicine.
Lauren Griffith
Dr. Landi is highly knowledgeable and skilled in the field of functional medicine, but he also possesses a genuine empathy and compassion that is so often lacking in the traditional healthcare system. Dr. Landi connects to each of his patients on a personal level, works with you every step of the way, and makes you feel supported while navigating challenging health obstacles.

I found out about the practice of Functional Dr’e last year and realized this is what I need! Finding Dr Landi so close to home was awesome. We appreciated his candor, knowledge and engaging personality. He exuded caring and interest in me and my situation. I feel he had repeatedly gone the extra mile for me so our collaboration is successful.

The metabolic baseline most weight loss programs skip. Fasting insulin and glucose together show insulin resistance that a glucose reading alone misses. The full thyroid panel covers TSH, free T3, free T4, reverse T3, and thyroid antibodies. Ordered through a local lab and billed separately by the laboratory; recent usable results are reviewed first rather than repeated.
105+ epigenetic biomarkers across nineteen systems, from one at-home blood spot, including nutrient status, inflammation, and metabolic and hormone patterns. It is the baseline membership is built on and the test that is repeated each quarter to show whether the plan is working.
TruHealth plus TruAge in one combined review: what to correct now, and the trajectory you are working against, with system-level scoring that shows whether metabolic health is the system under the most strain.
DUTCH ($650) when hormone production, metabolism, and cortisol rhythm would change the plan. GI-MAP ($813) when bloating, inflammation, or stalled progress points at the gut. Metabolomix+ ($729) when nutrient deficits and cellular energy are part of the fatigue. Each is chosen by your clinician, not ordered by default.
The introductory clinician call is $0. When a GLP-1 or another metabolic therapy is appropriate, it is quoted individually after evaluation, because what you are paying for is a managed, personalized plan: the therapy for a defined duration plus follow-up clinician consultations, standard shipping and supplies, and clinical oversight, not the price of a vial.
Longevity Membership members and Functional Medicine Corrective Program patients receive 15% preferred pricing on eligible GLP-1 and peptide protocol packages. Conventional bloodwork is billed separately by the laboratory. HFW is self-pay; HSA and FSA cards are accepted.
Most weight loss ends when the program ends. Membership is for people ready to make a commitment to healthy aging, or to longer-term corrective care and health optimization: quarterly retesting, a clinician who adjusts the plan as your results change, and coaching all year, with 15% preferred pricing on eligible GLP-1 protocol packages. Not every plan has to be a membership; focused care visits are available too.
Begins after a separate $450 initial TruHealth assessment, which includes a 60 to 90 minute clinician review. Bloodwork, medications, and treatments are purchased separately.

Short answers to what people ask before booking.
Most weight loss programs optimize for the number on the scale. HFW optimizes for metabolic health and body composition. That means looking at glucose regulation, insulin resistance, lipids, inflammation, hormone context, lean mass, and strength, not just weight. Medication may be one tool in the plan. It is not the plan. Nutrition, adequate protein, resistance training, sleep, accountability, monitoring, and a maintenance strategy are built in from the start.
A GLP-1 may be considered for an appropriate patient after clinical evaluation. It is not guaranteed, and it is not offered as a standalone product. An advanced care clinician reviews your history, metabolic context, risks, goals, and what is available in your state before any medication decision. Availability also depends on clinician authorization, pharmacy requirements, and the specific therapy involved.
HFW does not currently offer semaglutide. HFW evaluates appropriate metabolic options and prioritizes a plan built around metabolic health, lean mass preservation, nutrition, training, monitoring, and sustainable maintenance rather than appetite suppression alone.
No. Many patients make meaningful progress through metabolic evaluation, nutrition, resistance training, sleep, stress and habit work, and correcting contributors identified through testing. Medication is considered when it is clinically appropriate for that individual, not as the default starting point.
The introductory clinician call is $0. Medication and protocol packages are quoted individually after clinical evaluation, because a package price reflects the therapy for a defined duration plus follow-up clinician consultations, standard shipping, standard supplies, and clinical oversight, not the price of a vial. Longevity Membership members and Functional Medicine Corrective Program patients receive 15% off eligible GLP-1 and peptide protocol packages. Conventional bloodwork is billed separately by the laboratory.
Because losing weight and improving health are not always the same thing. If the scale drops while strength and lean mass disappear, the plan needs another metric. Lean mass supports metabolic rate, glucose handling, strength, function, and long-term independence. HFW tracks body composition, strength, and metabolic markers alongside weight so that progress means something durable.
Rapid weight loss of any kind can include lean mass, which is why HFW builds the plan around protecting it. That means adequate protein and total nutrition, progressive resistance training, a measured rather than fastest-possible rate of loss, symptom tracking, and monitoring body composition rather than weight alone. This is a general education point, not individual medical advice.
Clinician-selected testing may include glucose regulation and insulin resistance markers, lipids and lipoproteins, inflammatory markers, thyroid and hormone-related markers, nutrient status, body composition, and blood pressure. TruHealth is frequently used to establish a baseline and to measure change over time. Testing is selected because the result can change a decision, not because it is available.
It is a common and reasonable question. A standard panel may not include markers relevant to insulin resistance, thyroid function in detail, hormone patterns, inflammation, or nutrient status, and a value inside a population reference range is not automatically optimal for you. HFW starts by reviewing what has already been done, then selects testing that could actually change the plan.
Hormone patterns can be one contributor among several to body composition, appetite, energy, sleep, and how a person responds to nutrition and training. They are not the whole explanation, and a hormone result is interpreted alongside symptoms, timing, history, and metabolic context rather than treated as the single answer.
Not necessarily. HFW’s goal is to give you the best reasonable opportunity to maintain progress without unnecessary permanent medication reliance, which is why nutrition, strength, habits, and a maintenance or transition plan are part of the program from the beginning. HFW does not guarantee that every patient can discontinue medication. Some people may need continued treatment or another maintenance strategy, and that decision is clinical.
Your clinician reviews response, body composition, metabolic markers, and how sustainable your current plan is, then builds a maintenance or transition strategy appropriate to you. This is where a lot of weight loss programs end and where HFW’s model is designed to continue, through ongoing monitoring and plan adjustment.
There is no standard dose that fits everyone. When medication is clinically appropriate, your advanced care clinician selects a starting dose based on your history, labs, and goals, then adjusts it based on your response, tolerance, and progress. Dosing decisions are made through monitoring, not set once and forgotten. Medication access is not guaranteed, and every continuation decision remains a clinical one.
Structured check-ins between clinical visits that support nutrition, training, sleep, and follow-through. The goal is implementation. A plan that is not implemented does not change your metabolic health, so coaching is treated as part of the care, not an extra.
Rapid or poorly supported weight loss can cost bone and muscle along with fat, and both are harder to rebuild as you get older. HFW builds plans that prioritize adequate protein, resistance training, and monitoring so that losing weight supports long-term strength and function instead of undermining it.
