Understanding Set Point Theory and Bariatric Surgery

alexis • July 16, 2024

When it comes to losing weight, many people find themselves stuck in a frustrating cycle of shedding pounds only to gain them back again. One reason for this could be something called the “set point” theory. This idea suggests that our bodies have a certain weight range they naturally try to maintain, much like how a thermostat works to keep your home at a comfortable temperature.

What is Set Point Theory?

Think of your body as having an internal weight “thermostat.” This set point is determined by factors like your genes, metabolism, and hormones. When you lose weight, your body might respond by slowing down your metabolism and making you feel hungrier, all in an effort to return to that set point. Your body is essentially fighting to get back to what it thinks is its normal weight.

Bariatric Surgery: A Helping Hand

For those with severe obesity, diet and exercise might not be enough to break free from their set point. That’s where bariatric surgery comes in. This type of surgery changes the way your digestive system works, helping you lose a significant amount of weight and keep it off.

How Bariatric Surgery Works

  1. Hormonal Changes:  Procedures like gastric bypass can reduce the production of hunger hormones. This means you feel less hungry and can eat less without feeling deprived.
  2. Metabolic Boost:  After surgery, your body often becomes more efficient at using insulin, which helps control blood sugar levels and can boost your metabolism. This makes it easier to maintain a lower weight.
  3. Lifestyle Update:  Surgery is just the beginning. It’s a powerful tool that helps kickstart weight loss, but patients also need to commit to healthy eating and regular exercise. These lifestyle changes are crucial for long-term success.

Why It Works

The combination of hormonal changes, a faster metabolism, and new eating habits can help reset your body’s set point to a healthier range. Bariatric surgery can help with this, making it easier to lose weight and keep it off. Understanding how set point theory and bariatric surgery work together can be the first step toward lasting change.

How Bariatric Surgery May Reset the Body’s Weight Set Point

Bariatric surgery can help reset the body’s weight set point by making several changes:

  1. Hormones : Reduces hunger hormones and increases fullness hormones.
  2. Brain Signals : Changes how the brain controls hunger and fullness.
  3. Gut Health : Improves gut bacteria that help with weight loss.
  4. Metabolism : Increases the number of calories burned and improves how the body handles sugar.
  5. Eating Habits : Reduces cravings and changes food preferences.
  6. Stomach Size : Makes the stomach smaller, so you feel full sooner.
  7. Long-Term Changes : Keeps these changes over time to help maintain weight loss.

Differences in Set Point Changes Among Types of Bariatric Surgery

Each type of surgery affects weight set points differently based on how they change hormone levels, stomach size, and long-term weight management outcomes.

Gastric Bypass :

  • Alters gut hormones more significantly.
  • Increases calorie burning.
  • Often leads to more rapid weight loss compared to other types.

Sleeve Gastrectomy :

  • Reduces the size of the stomach.
  • Decreases hunger hormone (ghrelin) production.
These differences show why it’s important to personalize treatments to fit each person’s weight goals.

In many cases, there’s more to weight gain than just overeating. Obesity can result from underlying psychological issues that, if left untreated, can spiral to the point of seriously impacting quality of life. At over 500 pounds, Dennis R. was not able to enjoy life to the fullest. He isolated himself, despite having a supportive network and a job he is passionate about. Dennis shares his story of redemption, overcoming addiction and how his obesity was brought on by mental stress a lifetime in the making, in hopes of inspiring others. Dennis’s story is not an overnight success and his journey proves one’s discipline and persistence gives great results. Dennis’s family moved around a lot when he was a child. He was born in New Mexico, moved to Alaska as a toddler, and landed in Arkansas during high school. “I felt like a fish out of water,” describes Dennis. “Talk about culture shock, going from Alaska to the deep South. It was hard to make friends and I coped with that by eating an entire pizza daily after school. I gained over 100 pounds during my junior and senior year. My favorite sport was basketball, but the coaches said I was too heavy to play. I turned to football and played on the offensive line, earning a spot on my college team and eventually playing semi-pro ball.” Dennis traces his weight gain back to 1990. “The stress of moving from Alaska to Arkansas was really what kick-started the gaining for me, but I continued to make poor life choices in other areas as well as my diet. I eventually failed out of college, which only added to the emotional stress,” laments Dennis. “My weight was getting really out of control, so I tried diets like NutriSystem but as soon as I stopped them, the weight would come back and then some. I would lose up to 70 pounds and then gain it all right back.” Dennis was dealing with life-threatening medical conditions as his weight crept past 500 pounds. “I could hardly walk. I was constantly going to the hospital with swelling in my legs, chest pains, and cellulitis. I was taking multiple medications for diabetes and blood pressure,” Dennis says. “My coping mechanisms were consumption. I dealt with alcoholism and drug addiction by getting sober in 2006, but I never dealt with my food addiction and it was slowly killing me.” Dennis reached his breaking point in 2018. “I was sick and tired of being sick and tired. If I left the house, strangers would come up to me out of the blue and recommend weight loss surgery. It was embarrassing having to buy two seats on an airplane and buy size 7X shirts,” Dennis says. “I knew I needed surgery and as was the case with overcoming my addictions, I knew I had to be persistent and just do it. I looked at two bariatric practices in Alaska, and Anchorage Bariatrics really struck me as the place I needed to go. They have a great website and everything I read about them made me feel comfortable. I booked an appointment and was so glad I took that first step! The Anchorage Bariatrics staff are so friendly. Erika, Kristi and Tim are so supportive and understanding. Erika walked me through the whole process, the diet I would follow pre- and post-surgery, and answered all my questions. I love Anchorage Bariatrics. They feel like family.” In his first consultation with Anchorage Bariatrics, Dr. Clark told Dennis that he had to lose weight before surgery. A determined Dennis lost 43 pounds before his next appointment and Dr. Clark was impressed and approved surgery. Today, Dennis exercises daily. He walks during his lunch breaks and walks his dogs more, sometimes racking up six miles on a weekend. He says he thinks about his meal plan and makes sure he has everything he needs to prepare healthy meals. At only five months into his journey, Dennis has lost over 100 pounds; gone from a 56” elastic waistband to a 48; dropped three shirt sizes; doesn’t have to get a seatbelt extension on an airplane any more; and went canoeing for the first time since 1990! He is also weaning off his other medications and feels blessed not having to go to the ER all the time. “I used to isolate, I never wanted to go out of the house and be seen, I never wanted to talk to anyone, and I had very low self-esteem. Now, I go out to restaurants and go out in public and I don’t mind it. I have more energy now than I ever had,” shares Dennis. “The new stomach pouch created by my sleeve gastrectomy is a tool, not a cure all. I’ve learned that food is not everything. It used to be such a big deal for me, but now it isn’t all-consuming. I’m learning how to live and eat sensibly and it feels amazing,” Dennis says. “I’m grateful for all of the support from Anchorage Bariatrics, especially the psychological team, and I look forward to losing the next 100 pounds. You’ll hear from me again next year and you bet I’ll be at my goal weight. Nothing can stop me now!”

Since her Roux-en-Y gastric bypass procedure, Jennifer, an associate broker for a real estate company, has lost a total of 142 pounds. Jennifer shared, “While my childhood was average, during my teen and adult years, I yo-yoed over and over again with my weight. Diets worked initially, but I would hit a roadblock and once I would stall out for so long and didn’t see a difference, it was hard to stay motivated and I’d fall right back into the same issues.” Jennifer tried Weight Watchers and was successful for a while, but she could never prioritize working out.
