Keywords
GLP-1 Receptor Agonists
A class of medications that mimic the effects of a naturally occurring hormone called GLP-1, which regulates blood sugar and appetite. These drugs are used to treat type 2 diabetes and obesity.
Ozempic and Wegovy
Brand names for GLP-1 receptor agonists used for weight loss. Ozempic is approved for type 2 diabetes, while Wegovy is specifically approved for obesity.
Treat and Reduce Obesity Act
A proposed legislation that aims to improve access to obesity treatment by expanding Medicare coverage for weight loss medications and providing support services for patients.
Food Noise
A term used to describe the constant exposure to food cues and marketing messages that can make it difficult to maintain a healthy diet and manage weight.
Heterogeneity of Obesity
The concept that obesity is a complex and multifaceted disease with a wide range of contributing factors, making it difficult to treat with a one-size-fits-all approach.
Compounded Medications
Medications that are prepared by pharmacists using individual ingredients, rather than being manufactured by pharmaceutical companies. Compounded medications are not subject to the same regulatory oversight as FDA-approved drugs.
Q&A
What are the potential reasons for the recent decline in obesity rates in the U.S.?
While the CDC's survey doesn't pinpoint a single cause, experts suggest that the advent of weight loss drugs like Ozempic and Wegovy could be a contributing factor. Other potential factors include increased physical activity during the pandemic and changes in dietary habits.
How do GLP-1 drugs work to promote weight loss?
GLP-1 drugs act on the hypothalamus in the brain, upregulating the anorexygenic pathway (which tells us to eat less and store less) and downregulating the orexigenic pathway (which tells us to eat more and store more). This leads to reduced appetite and increased fat burning.
What are the challenges associated with accessing weight loss drugs?
The high cost of these medications is a major barrier to access, particularly for individuals on Medicare or with limited insurance coverage. Drug shortages and the lack of coverage by many insurance companies further complicate the situation.
What are the arguments for and against recognizing obesity as a chronic disease?
Recognizing obesity as a chronic disease can help reduce stigma and shift the focus from personal responsibility to a more holistic understanding of the disease. However, some argue that this could lead to over-reliance on medication and a lack of focus on lifestyle changes.
What advice would you give to someone considering weight loss drugs?
It's important to consult with a qualified healthcare provider who is knowledgeable about these medications and can assess your individual needs and risks. Discuss your insurance coverage and explore alternative treatment options if necessary.
Show Notes
The adult obesity rate fell to about 40 percent in 2023, down from 41.9 percent in 2020, according to the latest National Health and Nutrition Examination Survey from the CDC.
While the study doesn't pinpoint one sole reason for the change, the timing coincides with the rise of a new class of drugs targeting diabetes and weight loss, like Ozempic and Wegovy.
As part of our series In Good Health, we discuss these new medications and the falling rate of obesity.
