On today's edition of Beyond BMI, I'll be discussing weight plateaus. This is something that our patients are very familiar with. Sometimes, they're happy with their weight when they plateau; sometimes, they're not. A weight plateau is simply a state of equilibrium.
There's a common adage that the last 5 lb are the hardest. When people decrease their calorie intake and increase their activity — as we instruct our patients to do to lose weight — the body starts to fight back because it believes this is a famine state. Our bodies feel that we are running around the jungle looking for food to help us survive a perceived famine state.
The body does a few things to help us keep weight on, and this is what leads to the frustration of not being able to lose those last 5 lb. The first thing that happens in this process, which is called metabolic adaptation, is that when someone loses weight, the body naturally increases appetite signals from the brain, so the person becomes hungrier. Satiety signals from the stomach also decrease, so they feel more hungry and less full. And finally, stable fat cells form to allow the person to seek out more food without losing weight. This eventually leads the patient to regain weight, or they may plateau at a weight they're not happy with.
I'm sure you've seen many studies looking at weight plateaus and the amount of weight loss people are able to achieve with diet, exercise, and behavior change alone vs the same lifestyle modifications plus medication. Studies show that patients who are taking anti-obesity medications achieve far more weight loss than do those who are not taking medications. The reason is related to the different mechanisms of action of the anti-obesity medications. Patients taking these medications are able to tolerate a lower caloric intake for a longer period of time, thus they're able to burn more fat cells and lose more weight. Some medications perform this by decreasing appetite signals, so patients can continue to eat a small number of calories. Some medications affect the stability of fat cells. Some medications also increase satiety signals, so patients can move beyond that degree of metabolic adaptation and get beyond their previous plateau.
What can we do for patients who are frustrated with their weight plateau? I recommend taking a dive into their daily routine. Find out how many calories they are eating. Find out how much exercise they are doing and see whether there's any room to reorganize the day or change their meals to create a caloric deficit. Are they eating things that are not filling enough, so they can't get to the next meal without having a snack in between? We are looking at the quality of the meals as well and making sure there's an adequate amount of protein and fiber in their meals to help with those increased appetite signals. We should also make sure these patients are getting adequate fluid intake.
These are all strategies that can help our patients try to get beyond their weight plateaus.
If the patient meets criteria for anti-obesity medication, which means a body mass index (BMI) of 27-29 with a weight-related comorbidity or BMI ≥ 30 with or without a comorbidity, you may want to consider anti-obesity medication to help that patient get beyond the plateau.
Plateaus will occur as a natural process because of the appetite signaling and hormonal changes that occur when patients lose weight from any modality. It's important that we work with our patients to determine whether their weight plateau is due to metabolic adaptation. If they aren't meeting their goals and they have weight-related comorbidities, we can use other available modalities to help those patients continue to lose weight. Of course, whenever we are prescribing a medication, we need to make sure that it is safe for the patient and the patient is on board with the potential side effects and risks. And we should always make sure our patients know we are their advocates in their weight journey.
