Nadia B. Pietrzykowska, MD, FACP

Obesity Medicine, Physician Nutrition and Aesthetics Specialist

Founder and President of Weight & Life MD, LLC

Dr. Nadia B. Pietrzykowska is a renowned practicing physician board-certified in Obesity Medicine, Medical Nutrition and Internal Medicine, and a Master Certified Aesthetics Specialist. She is also an author, lecturer, teacher and entrepreneur.



     We provide you with a personalized, medically-supervised treatment of obesity and related medical conditions, by implementing the latest medical guidelines and research in the field of weight management in addition to lifestyle improvement to ensure that your weight loss is permanent and you can become a happier, healthier person overall.

     It doesn't matter whether you want to make your first attempt successful, you've tried multiple diets in the past, or are regaining weight after surgery - we have a plan for you.

     In our Clinic you will meet passionate, highly trained professionals who will go out of their way to help you achieve your goals. We provide everything you need for successful and long-lasting weight loss: personalized nutrition plans, behavior change support, physical activity coaching and weight loss medications prescribed by a specialist.

     One-on-one sessions with our doctors are stress-free and centered around our patients, with a focus on your needs and preferences. Our goal is a seamless partnership with you, for a lifetime of success in maintaining your optimal weight and health.  We offer in-office and telemedicine appointments in several states.

     The metabolism of each individual is different. It is important to measure it precisely in order to design an optimal weight loss plan. In our clinic we don't guess your metabolism, we measure it using state-of-the art machinery! This is done directly and with great precision.
The test is not only painless and quick but is also quite powerful.
     Our Physician Nutrition Specialist will measure, analyze and explain to you your specific basic metabolic rate, the number of calories your body needs to maintain all basic physiological functions, and a safe calorie deficit for healthy weight loss. Measuring your metabolism directly will help us design a successful weight loss plan, tailored just for you.

     Weight loss should not mean muscle loss. And it doesn't - in our clinic. We use a state-of-the art, fast and non-invasive body composition analysis device to determine the amount of muscle, fat and water in each part of your body. This allows us to design optimal nutrition and exercise plans, so you lose fat tissue while maintaining your muscles.
     Our Medical Exercise Specialist can even design exercise plans specifically for gaining muscle mass. To track progress, we recommend repeating our body composition test periodically to precisely determine your losses and gains.



     Have you read about new weight loss medications recently and want to see if they are right for you? Or are you skeptical? You need a board-certified Obesity Medicine Specialist trained in proper use of weight loss medications to answer these and any other questions you might have.
     Pharmacotherapy should be done in a very personal manner. Only a trained specialist, just like ours, knows exactly how to prescribe any of the several FDA-approved weight loss medications available currently on the market, and tailor them to your needs if necessary.

     Proper nutrition is a staple of successful weight loss. With hundreds of different diets, each claiming to be the best, it is hard to know what to do. Should I use organic, probiotic, gluten-free food? Are meal replacements OK? How about a ketogenic diet? Does it make sense to follow a paleo diet if I'm not living in a cave anymore?


     Our Physician Nutrition Specialist will answer all of your questions, and evaluate and treat potential nutritional disturbances related to chronic diseases of the gut as well as other chronic and acute disease states. We will achieve success together by creating a plan just for you, and guiding you closely throughout your weight loss.


     Can you lose weight just by restricting your calories? Yes, you can. However, you’ll likely quickly regain that weight unless you make important behavioral changes. Changes in behavior are essential for maintaining successful weight loss, but of course, each person is different.


     Our Behavioral Change Specialist will first help you understand the specific reasons underlying that unwanted, excessive weight. Then, by implementing principles of positive psychology and strengths-based coaching, we will foster your self-improvement and development of healthier habits. Successful weight loss in our clinic means adjusting your lifestyle as a whole and helping you becoming a happier you.


     Can you name 3 benefits of  regular exercise? We’ll give you 10: it strengthens your heart, clears arteries, stabilizes blood pressure, strengthens the lungs, reduces blood sugar, improves your blood lipid profile, strengthens bones and joints, prevents several cancers, increases energy and lessens depression. You can have these benefits at any age. Isn't it great? And yet, it is still difficult to keep a regular physical activity routine in our busy lives.
    Our Medical Exercise Specialist will help you stay motivated and on target. Regardless whether you hate exercising, or maybe you’re a “gym rat” but got injured, or love exercising but have physical limitations - we will help you. No matter the situation, we will create your personalized, physical activity plan with achievable goals based on our principles of healthy fitness, so you can get all of the benefits of regular exercise.

During this informational session with our Health Coach done over the phone, you and we will assess whether our Clinic is the right fit for you. We’re here to listen and you are here to share your concerns, medical problems, prior weight loss attempts, and lifestyle goals. You will also learn from us what we offer to make your weight loss journey a success story. If you decide, as many do, to join our Clinic, you will next book a visit to evaluate your metabolism and your body composition (booking fee of $175 will apply). We will also send you some forms to fill out to determine how better we can help you, scripts for blood work and for EKG, and provide you with an access to our exclusive app.

TEST DAY ($175)

During the Test Day you come to the Clinic and we perform two non-invasive, painless tests using state-of-the art machines to determine both, your body composition and your metabolism. This appointment can be scheduled even for the day right after your Orientation depending on availability. At the end of the Test Day appointment we will schedule you for the Initial Medical Visit, during which you will meet Dr. Nadia (booking fee of $175 will apply).


After receiving the results of all of your tests including your blood test and EKG Dr. Nadia is ready to meet you. During this telemedicine visit (via the Weight & Life MD app) Dr. Nadia will perform your physical evaluation, behavior readiness assessment, nutritional assessment, body composition and metabolism analysis; will discuss medications and the use of meal replacements; will create a treatment plan just for you. This is when your weight loss begins!

We provide the most comprehensive weight loss plans. After the Initial Medical Visit kick starts your journey, there are several plans for you to choose from.
