Weight-loss medications called GLP-1s are gaining traction, but experts caution about their long-term effects. Dr. John Lewis, a nutrition specialist and professor, shares some valuable insights.
What are GLP-1s and How Do They Work?
GLP-1, or glucagon-like peptide-1, helps the body release insulin. Drugs that mimic GLP-1 can boost insulin production after meals, slow down digestion, and help you feel full longer. By curbing hunger, they can aid weight loss, especially for those who find it hard to control their eating.
What Are the Long-Term Risks?
These drugs are relatively new, with the first one approved in 2014. This means we don’t yet fully understand their long-term effects. Some concerns include:
- Slowed digestion, which might affect gut health.
- Possible muscle loss, making it harder to burn calories over time.
- Reports of vision issues and unknown interactions with other medications, like antidepressants.
How Do GLP-1s Affect Weight Management?
Dr. Lewis points out that while GLP-1s can offer quick results, they may lead people to ignore deeper issues like unhealthy habits. If lifestyle changes in diet and exercise aren’t made, weight can come back after stopping the medication.
What Should You Consider Before Using GLP-1s?
Before starting on GLP-1s, it’s crucial to think about the potential risks. Dr. Lewis encourages tackling the root causes of weight gain—like diet and exercise—instead of relying solely on medication.
According to recent studies, about 40% of adults in the U.S. are considered obese, and medications like GLP-1s are seen as a quick fix by many. However, experts emphasize that true weight management requires comprehensive lifestyle changes.
Understanding GLP-1s is important. They might help you lose weight, but they should be part of a broader approach to health, focusing on nutrition and active living. Always consult with a healthcare professional before making changes to your health regimen.
