Leptin & Ghrelin: The Sneaky Hormones Sabotaging Your Hunger After Bariatric Surgery
May 05, 2025
The Rewrite Lifestyle Center helps individuals overcome food addiction, emotional eating, and stress eating through expert bariatric nutrition, mindset coaching, and sustainable healthy habits for long-term weight loss success.

 

After bariatric surgery, most people focus on macros, supplements, and hitting protein goals—but few talk about the real drivers of hunger and fullness: your hormones. Specifically, leptin and ghrelin—the ultimate frenemies in your post-op life.

Let’s break them down:

  • Leptin: The “I’m full” hormone that signals your brain to stop eating.

  • Ghrelin: The “FEED ME NOW” gremlin that screams for food—even when you just ate.

In a healthy system, they work together beautifully. But after surgery—and years of yo-yo dieting or eating ultra-processed foods—that system gets hijacked.

 

🎯 What Happens to Leptin & Ghrelin After Surgery?

  1. Ghrelin levels drop post-op, especially after procedures like the gastric sleeve, which reduces the stomach's ghrelin-producing area. That’s why many bariatric patients don’t feel hungry at first.

  2. Leptin sensitivity stays broken. Decades of sugar crashes, binge cycles, and starvation diets mess with your body’s ability to hear leptin’s "you’re full" message.

  3. Processed foods post-op = hormonal chaos. Yes, even the "healthy" stuff labeled high protein can confuse your system, making you feel constantly unsatisfied.

🍽️ Why Ultra-Processed “Health” Foods Keep You Hungry

Let’s be real: most protein bars and “fit” snacks are just candy bars in disguise.

  • Artificial sweeteners

  • Seed oils

  • Sugar alcohols

  • Zero actual nutrients

These foods don’t nourish your body—they stimulate cravings. In fact, many of these snacks are chemically engineered to override your fullness signals and keep you eating.

They’re tested not for how nutritious they are, but for how fast and how much people eat. That’s addiction science—not nutrition.

 

🥑 Whole Foods = Hormonal Reset

You didn’t go through bariatric surgery just to be tricked by your hormones.

Shifting to a whole foods-based diet can help:

💪 Stabilize ghrelin and leptin levels
📆 Support real hunger cues
🚫 Reduce cravings and “dopamine hits” from junk foods
🙌 Create peace between your body and your plate

Foods like lean proteins, fiber-rich veggies, and healthy fats help your hormones work for you, not against you.

⟳ From Willpower to Hormonal Wisdom

Shenelle and her team have big hearts and are truly here to help people. In a little while over a week I'm down 5 pounds just by cutting out the ultra processed protein snacks and artificial sweeteners. She is the real deal and won't steer you wrong!

Danaye Henken

I found Shenelle and the Rewrite just after my 1 year sleeveiversary. I was training for my first marathon taking guidance from a nutritionist who is also a runner but knew nothing about life after bariatric surgery. I had regained 16lbs in the span of about a month and was miserable. I started Shenelle a program and INSTANTLY felt like I was home. The community, the support and the program. It was hard work, but the kind that’s rewarding because it changes your life. In 4 months I went from 188lbs to 149lbs and I’m about to run my SECOND marathon. I’m stronger physically but also mentally. After being in this community for a while, Shenelle offered me the opportunity to give back to the same people who helped me. I’m proud to say I’m one of the coaches here now. Sharing my story and helping people on their journey to living their best life.

Kathleen Sloan Holdsworth

I was struggling from 25 lb regain 7 years post surgery. My weight-loss team abandoned me and offered me zero help. I was afraid I would put on all the weight I lost (98 lbs) if I didn't find help.
I joined Bariatric Rewrite and learned new techniques for someone years out from my surgery. The peer support and community is a huge portion of what I need to keep me on track. There is a no excuses attitude with the program. I need that to  keep honest with myself and the scale.
I recommend the Rewrite for anyone on the surgical journey. It is essential for learning how your new body works and how to maintain the progress one obtains with WLS. I lost the regain and feel great, once again.

Rita Hernandez

If you have had or are planning to have bariatric surgery then you’re in the right place. Since I joined 10 months ago I found the support I needed to be successful. I’m down 100 pounds in 11 months post surgery and I could not have done it without the Bariatric Rewrite Academy, my coaches Shenelle and Seda and all the community. Thank you!
 

Mary Parton-Bultmann

I have been with Bariatric re-write for over a year and it has been life-changing. I am a revision patient and never had support following surgery. I have learned how to fuel my body appropriately. I have also been able to address my food addiction in a safe, caring and knowledgeable community.. I’ve lost 172 pounds with Bariatric re-write guiding me and educating me and never abandoning me in the process. If you’re looking for real support following bariatric surgery, using a GLP-1, or just trying to wrap your head around how to fuel your body appropriately. Bariatric re-write is where it’s at.

Nicki Mitchell

Joining the Bariatric Rewrite has been a game changer. You have 24/7 access to community support. These folks know what your going through! There is so much education, support, and just great people. All positive and well worth it!

Colleen Myers

The academy has made such a difference in my life. I started my journey with Bariatric Rewrite last august pre-op. Shenelle guided me through a pre-op diet, supported me when I got my surgery date and helped me navigate the post surgery eating. She continues to be supportive as I continue my struggle as food addiction. The group chat is supportive when you run into different situations related to weight loss or about something about being a food addiction. I’m so grateful for the program and how it had changed my life!

Even though I have been with The Rewrite program for a few weeks, I made the best choice ever! I have been thinking about going back and forth for a while and I am glad I am here. The amount of support and knowledge I am learning about the food I have been eating and how to be able to control my food addiction is such a powerful experience. It's rough but like Shenelle and Danaye says it gets tough at first but it will get easier!

I have been with Shenelle and Seda for less than a month and have lost 9 pounds. I love the support and resources provided!

Ashley Dean

I started working with Shenelle and Danaye just three weeks ago, and I've already lost 12 pounds! Shenelle has completely shifted my understanding of food—she breaks down how your body actually processes whole, nutritious foods versus the junk we often consume. It's eye-opening!

What truly sets Shenelle apart is the time and attention she dedicates to each of her clients. She doesn’t just offer advice; she supports us every step of the way, guiding us toward success with honesty and integrity. There’s no sugar-coating, just real talk and practical advice. She makes the tough parts of life and health feel fun and empowering. Raw-dogging life with Shenelle isn’t just a catchphrase—it’s a lifestyle. If you're looking for someone who will give it to you straight and help you thrive, she's the one to work with!

Amanda Caldwell

There isn't enough good to say about this company. I joined the Acadamy in Nov 2023 and I will be a life long member. I have learned so much from Shenelle Coplien; she really motivated me to care about myself and to take back control of my life and health from my addictions. I will never be able to thank her enough. I encourage anyone who is struggling with their health and/or food addictions to take a chance and see what Bariatric Rewrite can teach you.

Jessica Newcomb

I joined the Bariatric Rewrite about a month ago. I had surgery 5 years ago and never got to my goal. I was regaining weight pretty quickly until I found Shenelle. In a month I’ve lost over 10 pounds after I was coached and taught how to deal with my food addiction. This community is amazing and keeps me accountable. The only regret I have is I didn’t have this community 5 years ago!

Lauren Mozuch

I don't even know where to begin. The Rewrite has been absolutely life changing for me. I started with them several weeks prior to VSG surgery and started making changes before my pre-op diet. Through this whole journey I have felt armed with information and totally supported. I would recommend the rewrite lifestyle center to anyone struggling before during or after a weight loss journey of any kind. Whether is facing your food addiction or struggling to get in water and protein, or just finding out who you are after weightloss. The rewrite has your back.❤️

Mary Bolen Doyle

I signed with the Bariatric Rewrite 5mo ago thinking I couldn't lose weight. Turns out I just needed the guidance and support I found there. I've learned to deal with my messes up relationship with food and am now down 31lbs!

Billie Burhite

You know when something lands in your lap and it changes your life? That is exactly what Shenelle and The Rewrite did for me! I went from being a very confused bariatric patient to someone who was taught how to live a life without fear and anxiety. I eat a whole foods diet, I have eliminated all artificial sweeteners and I have won the battle with cravings. Well that's kind of a lie... The only thing that I crave are fresh, juicy, crunchy and healthy fruits and vegetables. My food addiction monster is under control and I am winning!

I not only hit my goal of 150 but I have continued to lose and my next goal is 132!

Thank you Shenelle for the giving me the tools to live my new amazing life!!!
