Nutrition

Learning more about nutrition in Raleigh is a vital component of patients’ post-bariatric-surgery health. Bariatric surgery results in changes in the volume of food intake and, in some cases, the absorption as well. While this positively affects weight, it can also lead to a decrease in nutrient intake. To address this, the patient must adopt a new diet that provides the essential nutrition the body needs to stay healthy and function properly.

Nutrition Plans

At Rex UNC Health Care Bariatric Specialists, we provide comprehensive nutrition plans for our patients. This allows us to ensure patient health and safety and long-lasting results long after the surgery itself is complete. Our dedicated staff of registered dietitians are ready to assist you with:

  • Pre-surgery diets
  • Post-surgery diets
  • Meal planning
  • Grocery store tours (virtual)
  • Post-surgery vitamins
  • Post-surgery protein

Combine Rex UNC Health Care Bariatric Specialists’ staged bariatric eating nutrition plan with a suitable exercise regimen to keep your weight loss on track after bariatric surgery. You’ll start on clear liquids the same day as surgery. Once you are home you will advance to full liquids (protein shakes, cream soups, Greek yogurt for 14 days. You will begin taking vitamins in the first week. On day 14 you can start a puree diet for 14 days; advance to a soft diet within a few more weeks, and then gradually reintroduce solid foods.

BARIATRIC SURGERY DIET

Gain the most from your surgery, and head off complications such as nausea, by learning to:

  • Eat slowly (30-45 minutes for a full meal).
  • Chew fully (at least 30 times per bite).
  • Take smaller bites.
  • Avoid drinking for 30 minutes before or after eating.
  • Pay attention to signs of fullness, such as pressure just below your ribs or heartburn. Overeating even a little can trigger vomiting.
  • Get used to measuring your food, and wait a few minutes before you finish eating to decide whether you’re satisfied.
  • Turn to our registered dietitians for ongoing nutrition counseling.

DINING OUT

Feel comfortable eating out with friends and family, but take charge of what you order. Plan ahead and research restaurants’ menus whenever possible. This will allow you to ensure that healthy options are available, giving you the chance to search for those options at your own pace. Don’t be afraid to ask questions or request exceptions that are not on the menu, including:

  • Smaller portions, shared entrees or children’s menu sizes
  • Sauces or dressings on the side, added sparingly or not at all
  • Non-fat or low-fat options

HOLIDAY EATING CHOICES

Stay focused on your meal plan during the holiday season, when more food options (especially less-healthy choices) are available at social events, parties and celebrations. Eat before you attend a holiday gathering to protect yourself against overeating once you get there. Enjoy the company of your family and friends away from the food buffet.

Learn the benefits of snacking, the basic steps for planning your snacks, and try some creative low-calorie recipes that taste good and satisfy your hunger.

AVOID CERTAIN FOODS

Eat foods high in protein and nutrients—especially foods included in our bariatric recipes. Stay away from foods that may be hard to tolerate, including:

  • Bran
  • Bread
  • Carbonated beverages
  • Coconut
  • Corn and legumes
  • Dairy
  • Dried fruit
  • Fried foods
  • Pasta
  • Skins from fresh fruit
  • Sugary foods

Replace desserts with fresh fruit, and give up alcohol. Sugary desserts create glucose spikes in the blood. In response, the body creates more insulin, which causes fat cells to take in more calories, causing weight gain. High sugar intake also results in a resistance to the hormone that signals the feeling of fullness. This is self-perpetuating because eating desserts creates a higher tolerance over time, resulting in the need for more of a sugar hit every time. Alcohol contains a lot of empty calories. It also causes the body to concentrate its energy on trying to burn those calories instead of fat and carbohydrate calories. And because alcohol activates neurons associated with the feeling of starving, it causes increased food intake, particularly high-fat high-salt foods. Alcohol increases galanin, a neuropeptide that also encourages food intake. Additionally, the cortisol spikes from alcohol cause the body to store more fat. When possible, choose foods that are broiled, grilled, baked, steamed or poached, rather than fried. Try to avoid vegetables and meats cooked with fats. Fried food can add a lot of calories, which can cause a nutritional imbalance.

BARIATRIC VITAMINS

Follow your care team’s instructions on taking vitamin and mineral supplements. You’ll need these for the rest of your life to help your altered stomach absorb all the nutrients your body needs. Patients primarily need to take multivitamins, capsulated B vitamins, calcium, vitamin D3, and iron. These are essential for prevention of common health complications after bariatric surgery. These health risks include anemia (B12 and iron deficiency), neurological complications (potentially related to a deficiency in vitamin B1), compromised bone integrity (lack of calcium), and kidney issues (due to changes in vitamin D absorption).

Dr. Lindsay Sharpe is the best. His bed side manner is extraordinarily exceptional. He listens to your concerns. His recommendation for the best surgical procedure is geniune and authentically honest. He is detailed oriented ensuring that patients are fully informed and understand the before, during, and after care required; as well as, any risks that could occur, which is typical for any type surgery performed. His professionalism, bedside manner, and dedication to a healthier "you" is outstanding and award winning. He is truly a gifted and talented medical doctor. I feel a higher power than I brought him into my medical journey. Dr. Sharpe my prayers for you are that God continues to keep his hands upon you and bless you beyond your greatest expectations!❤️🙏🏽❤️

Dr. Sharp is amazing! The staff are friendly and very knowledgeable! He takes time to explain and answer any questions… only thing I would change would be the difficulty of getting someone on the phone. I usually result to online scheduling or messaging.

Dr sharp is the best . He did my surgery on October 17th 2022 and ever since then I’ve been doing great . He always explains things to me listening to my questions and concerns . He always makes me feel at ease no matter the situation even when I feel I’m doing terrible even though I’m not he always makes encouraging me and saying how proud I should be of myself and how proud he is of me and how great I’m doing. I honestly used to dread going to the dr and getting weighed on the scale now I look forward to when I have to go see Dr sharp and his team they are always so awesome and always patient with me . I lost over 100 lbs since he did my surgery and still working to lose more I’d give Rex bariatric more then five stars if I could . I’d recommend them to anyone looking into bariatric surgery go see Dr Lindsey sharp he is awesome and you won’t regret it . I’m looking forward to to my upcoming appointment with him

I had my gastric sleeve surgery with Dr. Dustin Bermúdez at UNC Rex on July 1st 2025, but my journey with him and his team started back in October 2024. Since then, my life has completely transformed—I’ve lost 150 pounds already & still working out to keep losing more & achieve my goal weight. I feel happier and healthier than ever. Best decision I’ve made! Dr. Bermúdez has been incredible throughout the entire process. He guided me every step of the way, providing the best tools and support to help me achieve not just weight loss, but also a true reconciliation with myself. His professionalism, care, and dedication are unmatched. I also want to thank all the nurses and medical staff who made this surgery such a success. A special thanks to Nurse Natasha (navigator nurse) & Miss Lauren Hawley (nutritionist), both were always attentive and supportive during my entire process. I am deeply grateful to Dr. Bermúdez and the entire UNC Rex Bariatric team for changing my life.

Fantastic experience all around! Dr. Bermudez was kind, professional, and explained more in 5 minutes than Wayne Memorial Hospital did in 9 days.

Truthfully it's complicated. Nobody goes into surgery cuz of the heart. It's either the money or they want to cut I get it. Communication from the front office and the doctors at the time of the appointment. Phone calls messaging on point, accurate five stars. Prompt, professional and always have the answers and seemingly the solutions. But I'm five surgeries deep & finding that the problem is a constant loop of endless surgeries. Got advice from a third party doctor who quickly reviewed my history but is not a specialist in this field. I scheduled a second opinion with Duke bariatrics later this month and will update according. Again customer service is great and I still have hope, I'm wondering if I'm in too deep And unfortunately my body picked a short straw, or if something was missed or inaccurately performed or whatever down the line. I'll be honest because of the prompt response and amazing customer service and addressing all my concerns including after hours and the complicated patient I've been. I feel guilty about seeking a second opinion but after the doctor explained it in simple terms (four surgeries at the time. Almost a month fresh on my 5th) deserves a second opinion no matter what.) Will update after the review, I understand nobody is 100% perfect and beyond the amount of surgeries and complications including loss of work, income etc. I will say five stars for communication, listening, addressing and seemingly finding a solution. Hopefully I am cracked and that assumption and the second opinion confirms it.

If I could give more stars I would! When I tell you DR. Crisp is THE BEST.... I swear by it!!! I was a bit skeptical at first because I couldn't find any reviews on him! However, from day 1 he made me feel comfortable, answered all my questions and explained the bariatric process throughly.Once my check list was completed I was in surgery 2 weeks later and let me tell you, this recovery has been AMAZING! I have heard horror stories about recovery but DR. Crisp and his team are magic!Thankyou Rex for this awesome experience !

I read a review with 2 stars, about malnutrition not enough protein, well my review will stress the importance of the whole process, and the importance the WHOLE staff stresses on post op. Rex Bariactrics is a whole process on food, supplements, exercise, mental health and overall wellness. This is the most comprehensive surgery process and the staff is top notch. I was over 280 pounds and after a year I am now 160 pounds. I did and continue to do exactly what the professionals have taught me. I have never felt so well and physically in the best shape I have ever been. Who was my surgeon- Dr. Bermudez. Dr. Bermudez and his staff are beyond exceptional. I cannot express in words how grateful, thankful and blessed I am to have had Dr. Bermudez has my surgeon, advocate and healthcare professional. His staff is equally amazingly supportive and knowledgeable. I had planned on this surgery years ago and had an inner gut feeling about other surgeons and never proceeded. I could not be where I am today without the jump start and help with Dr. Bermudez staff. Even after a year if I ever contact the office I get a response immediately with correct correspondence. Happy New Year to Dr. Bermudez and his staff, I am forever grateful to have you in my life.

Review for Rex Bariatrics I have been a patient at Rex Bariatrics, and my experience has been very positive overall. My first impression during check-in and waiting was average, but the technician who took my visuals stood out for being incredibly sweet and sincere. Before meeting the bariatric surgeon, they provide an informative video explaining the procedures they offer, which helps set expectations. My first impression of Dr. Sharp was that he was straightforward and efficient. While they see many patients and time is managed carefully, I never felt rushed. Visiting Rex Bariatrics feels similar to going to the dentist—you already have a problem and are there to fix it. Dr. Sharp gets straight to the point, discussing the procedure you are considering and addressing any risks, which are explained thoroughly in the video. Ultimately, I chose Dr. Sharp to perform my surgery, and I am glad I did. They also provide mandatory nutritional and psychological classes to help with the transition to a healthier lifestyle, which I found invaluable. Trust me, you’ll appreciate the support and guidance they offer. My experience at Rex Hospital was also excellent. The staff were friendly and caring. I stayed overnight for observation and was discharged 24 hours later with everything I needed for recovery. Of course, they make sure you’re ready before discharging you, even if it takes longer. I would highly recommend Rex Bariatrics and Dr. Sharp to my friends. Thank you to the entire team for helping me through this journey!

Dr. Sharpe is truly a sweet guy! He cares about his patiences, and works hard to help them. Not to mention the staff, they're all so sweet, walking into the office and seeing all of them smile makes me happy. (Even when I drive through Raleigh 🤣🤣) Thank you all so much!
