GLP-1 Receptor Agonists: A Possible Solution When Diet and Exercise Are Just Not Enough
The mantra “eat less and exercise more” proves ineffective, and even counterproductive, for many of us battling chronic weight problems, PCOS and complications of obesity.
While weight loss medication has been around for a very longtime, few have succeeded in promoting healthy, long-term weight management.
There are several new classes of weight loss medications currently in use but by far the new generation of hormone-based weight management medications, which mimic a hormone called glucagon-like peptide-1 (GLP-1), and is secreted in the gut and targets receptors throughout the body and brain, show great promise in providing an effective option between restrictive dieting and weight loss surgery.
But what are GLP-1 agonists?
GLP-1 receptor agonists mimic a protein that our intestines make when we consume food. When we eat, this GLP-1 protein sends the brain the “I’m full and satisfied” signal. GLP-1 also slows down the speed at which food exits the stomach which can help us eat less and also think less about food. We can feel not only full but also satisfied with smaller portions.
Here is an overview of the 2 ways GLP-1 receptor agonists can help with weight:
By making the stomach empty slower – we can feel satisfied and happy with smaller portions. This helps us eat less and attain the calorie deficit we need for weight loss.
By signaling the brain that our tummies are full, we will naturally have a decreased appetite and less cravings without all the side effects of traditional appetite suppressants that cause insomnia, tremors, and agitation. The GLP-1 helps us maintain more consistent food choices that can align with our body’s individualized dietary and nutritional needs.
Does it really work?
Yes! For example, the GLP-1 medication Wegovy, in addition to healthy lifestyle modifications, helped study participants lose 15 percent of their body weight on average. And more than half the people who used Wegovy lost more than 15 percent of their starting weight. That’s about 45 lbs. for a 300-pound patient and up to five times of the average weight loss achieved with diet and exercise alone!
Who should take a GLP-1 Receptor Agonist?
Anyone who has a BMI over 30 or BMI over 27 with associated co-morbidites like hypertension, insulin resistance, or cardiovascular disease and has failed diet and exercise to achieve a healthier weight. GLP-1 Receptor Agonist can even be a healthier option than traditional weight loss medication. For example, in people with chronic obesity and cardiovascular complications, GLP-1 receptor agonists are preferred to amphetamine-based therapies like phentermine, which can worsen hypertension, increase heart rate, cause anxiety, and insomnia.
Who should NOT take a GLP-1 Receptor Agonist?
Do not take a GLP-1 if:
What about insurance?
While this medication can be expensive, many health plans will cover a portion of GLP-1 medications. There are now a number of brands available for those who qualify and those brands offer various savings coupons too! Check out their websites:
