Our Philosophy - Evidence-Based
Our Philosophy

Evidence-Based Weight Management

Your Weight & Life MD team is committed to using evidence-based therapies to treat all weight concerns, whether it’s excess weight and obesity or inadequately low weight. The full spectrum of medical, behavioral, nutritional, genetic, environmental and physical fitness aspects is explored. These therapies are scientifically and medically proven options that follow treatment guidelines of nationally recognized medical societies as well as explore cutting edge solutions grounded in published scientific medical research.

Our medical approach differentiates us from commercial franchise weight loss programs and “miracle weight loss” solutions as it is not only comprehensive, personalized and innovative but also deeply anchored in scientific evidence.

A Holistic Touch

There is more than one reason why Dr. Pietrzykowska chose the name Weight & Life MD. Your weight concerns and your life are intertwined and connected. Your weight cannot be effectively managed without a thorough understanding of you as a whole person as well as the aspects of your life that may affect your weight.

We strive to help you reach your weight goal to enable you to live the life you want for yourself—a better, healthier, more fulfilling life. We also believe the changes you will undergo will not only have a positive effect on your health and life, but will also become an integral part of it.

As weight management professionals, we do not just treat your weight. Our goal is to understand you—your body, mind and social environment. This is the foundation of our holistic approach to weight management.

A Personalized Plan for a Healthy Life

If you are seeking weight loss:

  • Your plan will consist of an active weight loss phase, a transition phase and a maintenance phase. During your active weight loss phase, you will be seen weekly, medically monitored and your plan adjusted and modified depending on your overall progress and needs.
  • Appropriate nutritional guidance, behavioral changes and a personalized exercise plan will form the core of your plan. Instead of adhering to one rigid weight loss plan, our recommendations are individualized and optimized based on your progress.
  • Our nutritional treatment options vary from physician supervised calorie restricted diets including VLCDs (Very Low Calorie Diets), LCDs (low calorie diets) to a variety of diets with different macronutrient compositions specifically adjusted to your needs and your medical conditions (eg. Low carb, Low fat, Mediterranean, vegan, vegetarian, dairy free, gluten free, etc…)
  • We will recommend the use of weight loss medications whenever medically appropriate.

If you are seeking weight gain:

  • A thorough medical evaluation will be performed focusing on the medical condition causing your malnutrition and the nutritional deficiencies resulting from it.
  • The core of your therapy will consist of a personalized nutrition prescription along with the diagnosis and treatment of any deficits in vitamins, minerals and other essential nutrients resulting from your medical condition.

Cosmetic Options
Cosmetic Options

Non-invasive cosmetic weight loss

We are bringing you the latest technology in non-invasive, non-surgical, painless weight loss by offering FDA approved, laser-based cosmetic Body Contouring.

  • What is Laser Body Contouring?: It’s “inch reduction” using cold laser and targeting areas of your body like hips, thighs, tummy, etc…
  • How is it done?: We use the FDA approved Zerona device that has a long track of success and safety. Cold laser beams (no heat) are used to target areas where “inch reduction” is needed.
  • How long does it take?: Each single treatment lasts 40 minutes. A minimum of 6 sessions is generally recommended.
  • How does it work?: During these very relaxing and painless treatments, fat cell membranes become leaky and allow for their fat content to leave the cell, enter the extracellular areas and subsequently get absorbed and transported through the lymphatic system. A sensitive healthy lifestyle will allow for maintenance of the results indefinitely. Please follow this link for more information

You may consider laser weight loss if:

  • You do not want to undergo surgery and general anesthesia to lose inches in localized areas of your body.
  • After losing weight, you find that certain areas of your body seem resistant despite overall weight loss.
  • You’d like to improve your physical appearance for cosmetic reasons.
  • You’d like to boost the weight loss you are already attaining through all the medical, nutritional, behavioral and exercise-based methods we offer.

Is laser weight loss the right solution for you? Call 609-882-1686 to find out!

Your Doctor

Nadia B. Pietrzykowska, MD, FACP
Doctor Nadia B. Pietrzykowska
Dr. Pietrzykowska is the founder of Weight & Life MD and the Medical Director of the Clinic. She is a physician Residency-trained and Board Certified in Internal Medicine, and Fellowship trained and Board certified in both Obesity Medicine and Nutrition. She became a Fellow of the American College of Physicians thanks to her valuable contributions to the field of medicine.

Dr. Pietrzykowska is passionate about obesity and nutrition issues and believes that a healthy lifestyle is the foundation of health and well-being. She also understands that the road to healthy weight is often a journey with ups and downs that requires support and guidance.

Her involvement in helping individuals affected by excess weight goes beyond medical practice. In prior years, she developed a weight counseling program at a local Clinic that was designed to help some of the underprivileged urban population. This was received with much enthusiasm by both patients and physicians.

She benevolently collaborates with the Obesity Action Coalition, a national non-profit organization “dedicated to improving the lives of individuals affected by obesity” by regularly contributing to their Education Committee. This ongoing relationship resulted in multiple articles written by Dr. Pietrzykowska and featured in Your Weight Matters Magazine. She also speaks at their Annual National Convention.

Dr. Pietrzykowska is also involved with the scientific community through contributions to medical journals and other publications, active membership in multiple medical societies and attendance as well as presentations at scientific conferences.

“Dr. Pietrzykowska is one of the most compassionate, caring, and committed Obesity Medicine/ Nutrition Physicians I know. Her commitment to her patients and her passion for nutrition, weight management, and wellness are refreshing and invigorating. I wouldn’t think twice about sending my family and friends to Nadia…..

S A Hofmann

“No one was more pleased and surprised than I that I was able to lose so much weight in a few months without any chemical help. This was entirely due to the fact that Dr. Nadia described how to achieve weight loss, mostly by portion control and adding more variety to my meals.

I have tried 6 or 7 different weight loss programs, some worked, some did not, but this Weight & Life MD program works!

Thank you, Dr. Nadia”

Lorie Cafiero-Rende
“People struggle with weight for many reasons, I’ve struggled with weight most of my adult life for one reason or another. Over the last year, my husband was diagnosed with lung cancer. So my health issues were not a priority, I needed to focus on him and what I could do to make his quality of life better for the time we had together. Unfortunately, it wasn’t long after my husband was diagnosed that he passed away. But it was after he passed that I realized that I needed to focus on myself and my health. I have a 12 year old daughter and I needed to take care of myself so I can be around to raise her. I wasn’t eating healthy nor was I exercising and this was all taking a toll on my body both physically and mentally. A very good friend of mine told me about Dr. Nadia’s program and how successful it was for her, so I decided to go for the consultation. I have to be honest, I was a bit apprehensive at first and my fear was that I would be starving, but I thought let me go and see what it’s all about. First and foremost, I have to let you know that Dr. Nadia is wonderful, she makes you feel confortable, she explains everything to you and doesn’t rush you through your appointment; all your questions are answered. After my initial bloodwork, no surprise, all my levels were high. I was borderline diabetic, my cholesterol and blood pressure were high and my BMI was off the charts. I made a decision to go forward with the plan, and never looked back…I need to be honest, the first week was hard. Your body needs to get acclimated but as time goes by, your body adjusts, the hunger dissipates and the weight begins to drop. As each week went by, I began to feel less hungry and had more energy. A few weeks into the program, Dr. Nadia requested new bloodwork and I was pleasantly surprised as all my levels had dropped. As I continue to lose weight, they continue to drop. I started a regular exercise routine and each week not only did I see weight loss but I felt amazing. I was starting to feel like my old self again and my family and friends started to see a difference in me. To date, I’ve lost 31 lbs. I am still a work in progress but I’m focused and I know I’ll achieve my goal this time because I know that life is short and very precious and we must not put off what we can do today until tomorrow because we don’t know if tomorrow is guaranteed. So why not start feeling and looking your best today!”
Suzette Seda
“Almost a year ago I nervously meet Dr. Pietrzykowska and her staff after dealing with hyperglycemia and fainting twice in six months. My weight was not too bad however, after losing my Grandmother and three of her sisters to diabetes, I decided to take control of my destiny and make some changes. Just kept reminding myself that if I lost any more control it would mean sickness and insulin the rest of my life. From the moment that I walked into the office, Dr. Pietrzykowska and the entire crew welcomed me and put my concerns to ease. Dr. Pietrzykowska took the time to examine me and learn not only about my eating habits and lifestyle but, about my family. She got to know me as a person not just a number. With each session, she takes the time you need as an individual. If you happen to need more coaching any particular week she shows her dedication and takes the time, whatever the cost to her. Her main concern is that you leave feeling comfortable with your choices and goals. Today, I have lost about 32 pounds and my sugar is completely normal. Most importantly, I have learned the tools that I need to make the right choices and I am proud of the fact that I took control and made a difference. I actually did not eat horribly, I just needed some expertise on the right balance between carbs, protein and fats. Together, Dr. P and I worked on a diet and solution that got results within three months of my fist appointment with her. All about adapting healthy choices to match my lifestyle.”
Lewis Gran

She actively listens to your questions at every visit, responds to your questions with solutions that make sense. Dr. Nadia and her entire staff are always very welcoming and positive.”
Cathy P.
“Dr. Nadia is a great doctor. She is very knowledgeable about the latest scientific research on weight loss and related medical conditions. She is understanding of the struggles and frustrations those trying to lose weight go through, while helping them commit to making the necessary lifestyle changes. I have recommended many family members and friends to Dr. Nadia and many of them have benefited from her practice also. Her office staff is kind and organized and they are always on time with appointments.”
Nicole M.
“I worked with Dr. Nadia for 6 months and she has helped me reach my weight loss goals. After having bariatric surgery in 2005 and losing 70lbs, I hit a plateau. Dr. Nadia ordered comprehensive blood work before prescribing any medication or weight loss plan. Knowing she was very knowledgeable of how to treat a post bariatric surgery patients made me feel extremely comfortable with the quality of care I was receiving. Dr. Nadia helped me figure out my triggers and barriers, while allowing me to set goals for myself. Never did I feel like I was depriving myself. I absolutely love the fact that I could still have my favor snack each day. I am back in the gym and I am down 31 pounds. But most of all, I feel better than I have felt I a long time. I am so thankful to Dr. Nadia for her medical, nutritional, and emotional support.”
Rebecca Neil
“Dr. Pietrzykowska is a conscientious professional who truly cares for my health and personally works with me to help me grow and learn to gain control over my own eating habits. Following her program has guaranteed success for me in my weight loss.”
“Dr. Pietrzykowska’s program for weight loss is an easy program to follow that triggers my body to lose weight, teaches me to retrain my brain and listen to my body, and enables me to be in control of my life again.”
“Dr. Pietrzykowska is refreshingly honest with you. Her knowledge and dedication will help you if you listen. I only wish I found out earlier about her. I have my life back, I feel and look great and I am helping my entire family learn what I have.”
