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 609-631-9400 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.

Insurance Plans
Insurance Plans

What are the costs?

We participate with several health insurance plans. This differentiates us from commercial weight management programs and most other weight loss programs that generally only offer “out of pocket” options.

This said, coverage for obesity treatment varies between plans and even between policies within the same health plan.

If you are interested in joining our Program after attending your initial consultation with Dr. Pietrzykowska, we will discuss with you the extent of coverage offered by your specific plan.

How much weight will I lose?

This will depend on the aggressiveness of your plan, your metabolic rate, the amount of excess weight that you have and other physiological and behavioral factors. On average, our patients lose 20-30% of their initial weight but results can vary between individuals.

How fast will I lose weight?

This varies between individuals but both our patients and Dr. Pietrzykowska tend to prefer more aggressive weight loss plans, if medically appropriate to help you achieve as much weight loss as possible.

Are these plans safe?

All patients are very closely medically supervised. We match plans to your specific needs and medical conditions.

The weight loss phase is divided in 12 week blocks of weekly visits, what does this mean?

It means that every weight loss block lasts 12 weeks. We feel that this is enough time to achieve some meaningful weight loss in a manageable amount of time. After each block is complete, another block maybe started if medically appropriate and necessary.

Do I have to come weekly?

Yes. There are many reasons why this is necessary, both medically and behaviorally. We understand that you might be absent due to a vacation and will make an exception, but frequent absences will result in dismissal for the Program.

Are there any group classes?

No. All your visits are 1:1, with either the Doctor or a Counselor. In our individualized approach, we believe that these personalized visits allow us to optimize patient treatment and success.

What are the costs?

They will depend on the extent of coverage by your Health Plan. This will be discussed with you after your initial consultation with the Doctor and before you join our Program. Thus far, we have been successful in having the majority of patients obtain significant coverage through their health Plans.

Will I have a hard time with my plan?

Most patients are surprised as to how much easier this is than they anticipated. We understand that a good and successful plan is one you can adhere to. We keep that in mind at all times.

How is patient satisfaction with their journey?

Most of our referrals are from current or past patients and include their family, friends and coworkers. In addition, many area Doctors, both PCPs and specialists, have been referring their patients to us as they have seen them succeed with weight  loss and significantly improve or even reverse weight related medical conditions.

“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….. She is that good!”


James Zervios

Obesity Action Coalition
“The Obesity Action Coalition (OAC) has greatly enjoyed working with Dr. Pietrzykowska.

Together, we continue to develop a personalized plan to help me achieve success. Additionally, the office staff is friendly and helpful. I would recommend Weight & Life MD to any family member or friend seeking assistance with dietary needs and weight loss.”
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
“Dr. Pietrzykowska helped me resolve my eating bad habits and reduce my carbs , sugars and weight. Highly recommend.”
“Over the past 6 months Dr. Nadia has been working with me on weight challenges, she provides a scientific based approach, practical solutions related to changing your eating habits & lifestyle. She educates you on how to re-train your mind to ensure the development of a healthy lifestyle that will sustain your weight & health goals. 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.”
Stacy Whitehead
“Meeting Dr. Nadia was the answer to my prayers. I had struggled with weight loss as long as I can remember. It is because of her knowledge and wisdom, infused with the realities & struggles of daily life, that she was able to successfully help me reach my goals. In eight months, I lost 50 pounds! It was an amazing transformation for me. I can’t thank her and her staff enough!”
Irina Babayeva
“Over the past 3 months Dr. Nadia has been working with me on weight challenges. I had struggled with weight loss all my life, I have a prediabetes condition and stress eating. In 3 months, I lost 30 pounds! It was a great change for me.”
Denise Angel
“Dr. Nadia is very professional and compassionate for her patients. The program works and is highly recommended.”
Lou Schimenti
“I have just reached week 12 at Weight & Life and I lost 29 pounds so far. The plan is very easy to follow. Dr, Nadia is great, she keeps you on track. What I like about it is the food plan is simple and designed to you, after a couple of weeks you start an exercise program and you get weekly reading assignments to keep you focused. Seriously, if I can do it any one can do it. I still have a ways to go to reach my ultimate goal, but I feel better already.”
Patricia Rando
“I am so grateful to Dr. Nadia and her team! In the past, I ate well and exercised but my weight wouldn’t budge. The program set up by Dr. Nadia transformed my body! In addition to weight loss, I feel great and am off all medications. I received counseling, support, encouragement, and knowledge. I highly recommend Weight & Life!”
Anonymous-70 lbs lost without surgery
“I never would have thought that I could lose all this weight and maintain it. Dr. Nadia and her staff worked with me every step of the way. She pushed when it was needed and slowed down when my body was not cooperating. She kept adjusting my plan to allow me to lose more. She does not give up but also knows when it’s time to take a break even if I did not like it. She knew it was better for me and she was right. In all, I have turned my life around, my self-esteem and my medical problems. I lost 30% of my body! 70 lbs! I learned so much! Yes, it’s work but it pays off and I have learned so much about food and myself. I am so glad my doctor referred me to Dr. Nadia, otherwise I would still be my old miserable self.”
