In his new book, Ozempic: Risks, Benefits, and Natural Alternatives to GLP-1 Weight-Loss Drugs, Dr. Michael Greger, M.D., FACLM, explores the rapidly rising popularity of GLP-1 receptor agonists like Ozempic for weight loss. These medications, while promising, come with both potential benefits and serious risks. Approved for weight loss just four years ago, Ozempic has been widely adopted by those struggling with obesity. However, since it can take a decade to fully understand a new drug’s long-term effects (and potentially even longer to remove a dangerous drug from the market), it’s wise to approach with caution. This post unpacks the nuances of Ozempic’s benefits, risks, and natural alternatives highlighted in Dr. Greger’s work, providing a thorough look at whether this medication may be worth the gamble for some individuals.
How GLP-1 Receptor Agonists Work
Ozempic belongs to a class of drugs known as GLP-1 receptor agonists, which mimic the action of the hormone GLP-1 (glucagon-like peptide-1) in the body. GLP-1 regulates blood sugar, reduces appetite, and enhances feelings of fullness, leading to reduced caloric intake. This appetite-regulating mechanism can contribute to weight loss, and studies show that most users need to lose around 10% of their total body weight over the first year, leading to improved markers for blood pressure, blood sugar, and cardiovascular health. However, for those who see minimal weight loss or plateau before reaching this benchmark, the benefits may not outweigh the risks.
Plateauing: When Weight Loss Stalls
Ozempic's weight-loss effects generally plateau after about a year. Researchers found that around a loss of 34 pounds, the weight loss plateaued. For individuals who achieve a meaningful reduction of 10% in body weight, continued use can help sustain health improvements. However, for those who see only minimal weight loss, the risks of prolonged use may outweigh the limited benefits. Many users start using Ozempic while classified as obese and, despite some weight loss, remain within this category, often with added muscle loss. This minimal progress can actually increase health risks, leaving users more vulnerable to issues like metabolic decline and weakened physical resilience compared to when they started.
Risks of Ozempic and GLP-1 Agonists
Dr. Greger underscores multiple risks tied to GLP-1 receptor agonists, especially for those achieving limited weight loss benefits. Here’s a closer look at the primary concerns and their associated percentages:
Pancreatic Risks Research suggests a 58% increased risk of pancreatitis among GLP-1 agonist users, along with heightened risk for pancreatic cancer. This drug class can cause pancreatic abnormalities such as enlargement, dysplasia (abnormal cell development), and even small tumors. Long-term users, therefore, require careful monitoring for these potential issues.
Gastrointestinal Side Effects Nausea, vomiting, and diarrhea affect nearly 40% of users, especially during the initial weeks of treatment. In some cases, severe dehydration can result, leading to hospital visits and posing additional health risks.
Gallbladder Issues Ozempic and similar medications are linked to a 34% increased risk of gallbladder-related issues, such as gallstones and inflammation. These conditions may require surgical intervention if they become serious or recurring, adding further potential complications for long-term users.
Muscle and Bone Loss
Rapid weight loss with GLP-1 agonists often includes a reduction in muscle and bone mass, with studies indicating a 15-20% loss of lean mass in some cases. This can lower metabolic rate, reduce physical strength, and increase the risk for fractures or osteoporosis over time, particularly concerning for older adults or those with pre-existing bone density issues.
These statistics underscore the importance of considering both the benefits and risks of GLP-1 agonists, especially for individuals who experience minimal weight loss or other health gains while using these medications.
Risks of Prolonged Obesity
Increased Cardiovascular Risk Obesity raises the risk of heart disease and stroke by up to 64%. The presence of excess body fat often leads to elevated blood pressure, high cholesterol, and additional strain on the cardiovascular system. Achieving a 10% weight reduction can help lower these risks significantly.
Diabetes and Metabolic Syndrome Excess weight is the primary driver of Type 2 diabetes, increasing the risk by as much as 85%. Weight loss can improve insulin sensitivity, helping to reduce the risk of developing diabetes or better manage existing conditions.
Joint Issues and Inflammation With obesity, there is a 35% higher risk of developing arthritis and other joint issues due to excess weight and systemic inflammation. Reducing body weight can alleviate joint strain and improve overall mobility, particularly for those with osteoarthritis.
Increased Cancer Risk Obesity increases the risk for certain cancers, including a 30% higher risk for colon cancer, a 20-40% increase in breast cancer risk (especially in postmenopausal women), and a 90% increase in liver cancer risk. Maintaining a healthy weight can lower these cancer risks, making weight management an essential strategy for cancer prevention.
Achieving a 10% weight loss can help mitigate many of these risks, making Ozempic a potentially valuable option for those who meet this target. However, for those who do not reach a significant weight loss, the side effects associated with Ozempic—including risks of pancreatitis, muscle loss, and other adverse effects—may not be justified.
Natural Alternatives: Can We Mimic GLP-1 Effects Without Drugs?
For individuals hesitant to use GLP-1 agonists, Dr. Greger suggests lifestyle strategies that offer similar weight-loss benefits without medication. These natural alternatives have been shown to aid satiety, reduce cravings, and improve metabolic health. Here’s a look at some proven approaches:
Chewing Food Extensively Research shows that chewing food more thoroughly—aiming for around 40 chews per bite—can trigger earlier satiety signals. This mindful practice lets your digestive system communicate with your brain, releasing satiety hormones like GLP-1 in response to slower eating, helping you feel full with less food.
Incorporating Cinnamon and Other Spices Cinnamon, along with spices like turmeric, cumin, and coriander, offers natural appetite-regulating effects. These spices are known for their anti-inflammatory properties and blood sugar-regulating capabilities, which help curb hunger and prevent energy crashes.
Cinnamon enhances insulin sensitivity and stabilizes blood glucose.
Turmeric’s active compound, curcumin, reduces inflammation linked to obesity and may improve fat metabolism.
Cumin aids digestion and has been shown in studies to reduce body fat.
Using Vinegar for Satiety Vinegar, especially apple cider vinegar, has been shown to improve blood sugar response and increase satiety. It slows the stomach’s emptying rate, leading to a steady release of glucose and helping curb hunger for hours post-meal. Adding vinegar to water or using it in salad dressings can enhance satiety naturally.
Eating Fiber-Rich Foods Foods high in fiber, such as beans, vegetables, whole grains, and fruits, help boost satiety and regulate appetite. Fiber-rich diets also support gut health by promoting beneficial strains linked to reduced cravings and improved metabolic function.
Adopting a Plant-Based, Whole-Food Diet
A plant-based diet rich in whole foods like vegetables, legumes, and grains encourages natural appetite regulation and healthy weight management. This diet type supports gut health and promotes a balanced microbiome, creating a foundation for long-term satiety and weight control without artificial suppression.
Is Ozempic Worth the Risks?
For individuals who achieve a 10% reduction in total body weight, Ozempic may indeed be worth the risks given the health improvements tied to that level of weight loss. However, for those with minimal weight loss, the drug’s potential for pancreatic complications, muscle loss, and gastrointestinal distress may not justify the benefits.
Lifestyle interventions like mindful chewing, fiber-rich foods, and a plant-based diet can provide similar satiety effects and support sustainable weight management without the risk of long-term side effects. Dr. Greger emphasizes that these natural approaches promote health holistically, with long-term benefits to blood sugar, cholesterol, and gut health.
Disclaimer
Ozempic has been approved for weight loss for only four years, and it takes around 10 years to observe the full effects and safety profile of any new drug. As with any medication, especially those with recent approval, approach use with caution and consult your healthcare provider for guidance. Prioritizing safety is crucial, as it can take years to fully understand a drug’s risks and benefits.
My thoughts
As a CPT-SNS-LBS, I always advocate for a holistic approach to weight management through diet, exercise, and sustainable lifestyle changes. Supplements and weight-loss drugs often promise quick results, but in reality, they rarely deliver lasting benefits or address the root causes of weight gain and have horrible side effects. I understand the unique challenges and pressures that come with weight loss, and I know firsthand that it takes time, patience, and consistent effort, regardless of the path chosen. So before making any decision, be informed about the potential risks and long-term effects. Whatever route you decide, I'm here to provide support and guidance to help you reach your health and wellness goals in the best possible way.
