How Wegovy Helps People Take Weight Off and Keep It Off


Recent findings from the longest clinical trial to date on the weight-loss drug Wegovy (semaglutide) reveal promising results. Over a period of four years, participants experienced sustained weight loss and notable cardiovascular benefits. This article delves into the study’s outcomes, the mechanisms behind the drug’s effects, and its potential implications for treating obesity and heart disease.

Semaglutide is a medication belonging to a class of drugs known as GLP-1 receptor agonists. It is commonly prescribed for weight management and has been found to have significant effects on blood sugar levels, making it beneficial for people with type 2 diabetes.

The SELECT Trial

The SELECT trial, a pivotal study published in Nature Medicine, included over 17,000 adults with obesity or overweight who did not have diabetes. Participants received once-weekly injections of semaglutide and were monitored over four years to assess weight loss and cardiovascular outcomes.

Participants in the SELECT trial lost an average of 10.2% of their body weight over four years. Notably, weight loss continued for about 65 weeks before stabilizing.

  • Highest Dose Group: 68% of participants lost at least 5% of their body weight.
  • Placebo Group: Only 21% achieved a similar weight loss.
  • Significant Weight Loss: 23% of those on semaglutide lost at least 15% of their body weight, compared to just 1.7% in the placebo group.

These results are particularly impressive given that the SELECT trial did not include structured diet and exercise interventions, which were part of earlier studies showing higher weight loss percentages.

Beyond weight loss, semaglutide demonstrated significant cardiovascular benefits. Participants experienced a reduction in the risk of major cardiovascular events such as heart attack, stroke, and cardiovascular-related death.

The drug’s positive impact on heart health was observed even among those who did not achieve significant weight loss. This suggests that semaglutide’s benefits extend beyond mere weight reduction.

Mechanisms Behind Semaglutide’s Effects

Semaglutide’s effects are attributed to its ability to regulate appetite and enhance insulin sensitivity. It improves blood sugar control and reduces inflammation, which are critical factors in managing obesity and preventing cardiovascular diseases.

GLP-1 receptor agonists like semaglutide work by mimicking the effects of the natural hormone GLP-1, which increases insulin secretion, slows gastric emptying, and reduces appetite. These actions collectively contribute to weight loss and improved metabolic health.

The most common side effects reported in the SELECT trial were gastrointestinal issues, such as nausea and diarrhea, which typically occurred during the initial dose adjustment period. These side effects were manageable and led to a lower withdrawal rate from the trial.

The rate of serious adverse events was lower in the semaglutide group (33%) compared to the placebo group (36%), mainly due to fewer major cardiovascular events. However, an increased incidence of gallstones was noted among semaglutide users, a known side effect of the drug.

Long-Term Treatment Potential

The sustained benefits of semaglutide highlight its potential as a long-term treatment option for obesity. Given the chronic nature of obesity, semaglutide could be considered similar to medications for conditions like diabetes or hypertension, requiring ongoing management.

The high cost of semaglutide (approximately $1,349 per month) poses a challenge for accessibility. However, its demonstrated benefits in reducing cardiovascular complications could incentivize insurers to provide broader coverage, potentially lowering overall healthcare costs related to obesity and heart disease.

Further research is needed to explore the full extent of semaglutide’s benefits, particularly in individuals without obesity who have had previous cardiovascular events. Understanding the precise mechanisms by which semaglutide improves heart health will also be crucial for optimizing its use.

The SELECT trial underscores the effectiveness of Wegovy (semaglutide) in achieving sustained weight loss and significant cardiovascular benefits over a four-year period. These findings offer hope for individuals struggling with obesity and highlight the potential for semaglutide to play a crucial role in long-term weight management and heart health. Continued research and improved accessibility will be key to maximizing the impact of this promising medication.

They can assess your risk factors for certain diseases, offer guidance on lifestyle changes, and prescribe medications or treatments to manage any existing conditions.

Furthermore, routine checkups can help you establish a strong relationship with your healthcare provider. Over time, they will get to know your medical history, preferences, and concerns, allowing them to provide more personalized and effective care. This can lead to better communication, trust, and ultimately, better health outcomes.

Another advantage of routine checkups is that they can help you stay up to date on vaccinations and screenings. Vaccinations are crucial for preventing serious infectious diseases, while screenings such as Pap smears, mammograms, and colonoscopies can help detect cancer at an early stage when it is most treatable.

In conclusion, routine checkups are an essential component of maintaining good health and well-being. They offer numerous advantages, including early detection of health problems, personalized guidance on lifestyle changes, and improved communication with your healthcare provider. By prioritizing regular visits to your healthcare provider, you can stay on top of your health and ensure a longer, healthier life.

The Mediterranean Diet: Reducing Mortality Risk in American Women


The Mediterranean diet is widely known for its health benefits, supported by numerous studies across various populations. However, long-term data on its effects, especially among U.S. women, has been limited. A recent study by researchers from Brigham and Women’s Hospital provides new insights, revealing that a higher intake of the Mediterranean diet correlates with a 23% lower risk of all-cause mortality among American women. This diet not only reduces overall mortality but also shows benefits in reducing cancer and cardiovascular mortality.

The study, published in JAMA, followed over 25,000 initially healthy U.S. women for up to 25 years. Researchers found that participants who adhered more closely to the Mediterranean diet experienced significant reductions in mortality risk. The diet’s positive effects were linked to changes in several biological pathways, including metabolism, inflammation, and insulin resistance.

Understanding the Mediterranean Diet

The Mediterranean diet is primarily plant-based and includes a variety of nuts, seeds, fruits, vegetables, whole grains, and legumes. Olive oil, especially extra virgin, is the main source of fat. The diet also features moderate consumption of fish, poultry, dairy, eggs, and alcohol, while limiting the intake of meats, sweets, and processed foods. This diverse and balanced approach is believed to contribute significantly to its health benefits.

The researchers evaluated approximately 40 biomarkers to understand the biological changes associated with the Mediterranean diet. They found that biomarkers related to metabolism and inflammation made the largest contributions to reduced mortality risk. Other significant factors included triglyceride-rich lipoproteins, adiposity (body fat), and insulin resistance. Additional pathways involving branched-chain amino acids, high-density lipoproteins (HDL), low-density lipoproteins (LDL), glycemic measures, and hypertension also played roles, albeit to a lesser extent.

Implications for Public Health

The findings underscore the potential of the Mediterranean diet to improve public health by reducing the risk of metabolic diseases and related mortality. Dr. Shafqat Ahmad, lead author of the study, highlighted that even modest changes in established risk factors can yield substantial long-term benefits. This suggests that encouraging healthier dietary habits could significantly reduce overall mortality rates.

While the study provides valuable insights, it has some limitations. The participants were predominantly non-Hispanic, white, middle-aged, and older well-educated female health professionals. Additionally, the study relied on self-reported data, such as food frequency questionnaires and measures of height, weight, and blood pressure. Despite these limitations, the large scale and long follow-up period strengthen the study’s findings.

As the Mediterranean diet concept has gained popularity, it has been adapted in various countries and cultures. Dr. Mora noted that public health policies should promote the healthful attributes of the Mediterranean diet while discouraging unhealthy adaptations.

The Mediterranean diet offers significant health benefits, particularly in reducing all-cause mortality, cancer mortality, and cardiovascular mortality among American women. By understanding the biological mechanisms involved, this study provides a foundation for promoting healthier dietary habits. Encouraging adherence to the Mediterranean diet could lead to substantial improvements in public health and longevity.

In summary, the Mediterranean diet is more than just a dietary choice; it is a pathway to longer and healthier lives. As research continues to uncover the mechanisms behind its benefits, the importance of this diet in public health strategies becomes increasingly clear.

Fatherhood and Heart Health: Risks and Protective Factors


Heart disease is the leading cause of death among men, and recent research indicates that being a father may increase the risk of poor heart health later in life. A study by scientists at Northwestern University and Ann & Robert H. Lurie Children’s Hospital of Chicago examined the cardiovascular health of 2,814 men aged 45 to 84, revealing that fathers tend to have worse heart health compared to nonfathers.

Researchers evaluated participants based on several health indicators, including diet, physical activity, smoking habits, weight, blood pressure, and levels of lipids and glucose in their blood. The study found that fathers had poorer scores in these areas, suggesting that the added responsibilities and stress of fatherhood may hinder men from maintaining healthy lifestyles.

Insights from the Study

Dr. John James Parker, the study’s corresponding author, emphasized the need to view fathers as a unique population and to track their health outcomes as they transition into fatherhood. Cardiovascular health is crucial as it involves modifiable behaviors and factors, making it possible to improve through targeted interventions. 

Interestingly, despite having worse heart health, fathers in the study had lower rates of death compared to nonfathers. This paradox may be explained by the robust social support systems that fathers often have, including family members who help them manage their health. Additionally, fathers reported lower rates of depressive symptoms, which could contribute to their lower mortality rates.

The Impact of Race and Age

The study included a diverse group of men who self-identified as Black, Chinese, Hispanic, or White. Notably, Black fathers had lower age-adjusted death rates compared to Black nonfathers, suggesting that fatherhood might have protective health benefits for Black men. Further research into this association could have significant public health implications.

Men who became fathers at younger ages (25 years old and younger), particularly Black and Hispanic men, showed worse heart health and higher death rates. Younger fathers may face challenges such as financial instability, less mature decision-making, and lower-paying jobs with fewer benefits, making it harder to prioritize their health.

Public Health Implications

Dr. Parker highlighted the importance of considering fathers’ health in public health interventions. While there are many programs focused on young mothers, young fathers often lack similar support. Given that most men in the U.S. are fathers, understanding the health impacts of fatherhood is crucial for improving the overall health of families.

The study also found a higher smoking rate among fathers, which is surprising given that many fathers quit smoking upon having children. This could indicate that fathers might quit smoking initially but resume the habit later due to increased stress. Addressing smoking rates among fathers is important since smoking is a leading cause of preventable death and can negatively impact family health.

The study used the American Heart Association’s Life’s Essential 8 scores (excluding sleep) to define cardiovascular health and categorized men as fathers or nonfathers based on their responses in interviews. The findings underscore the need for targeted health interventions for fathers, particularly young fathers and fathers of color, to improve their cardiovascular health and, by extension, the health of their families.

To improve family health, it is essential to consider the interconnected health relationships among mothers, fathers, other caregivers, and children. By focusing on the unique health challenges faced by fathers, especially in the context of their role within the family, public health initiatives can better support the overall well-being of communities.
