The Role of Medicine in Achieving and Sustaining a Healthy Body Mass
The CDC’s latest numbers classify approximately 42 percent of Americans as obese, and over two-thirds of American adults qualify as either obese or overweight. Living with excess weight heightens people’s risk for debilitating and chronic but otherwise preventable conditions like stroke, type 2 diabetes, heart disease, and certain cancers.
With new weight-loss drugs like Ozempic and Wegovy on the rise, many are wondering if these medications live up to their hype and can even help end the obesity epidemic. Sergio Padron, founder and CEO of online healthcare and weight-loss support company MD Exam, believes they can — up to a point.
“It’s important to approach these medications with a thorough understanding of what they can and can’t do,” Padron says. “Magic pills for weight loss don’t exist.”
The importance of achieving a healthy body mass
According to Padron, achieving and sustaining a healthy body mass is key to good health. To obtain your body mass index (BMI), online calculators like this one from the National Heart, Lung, and Blood Institute ask for your height and weight, run them through the standard formula, and generate your score. The last step is to find this number in the standardized ranges considered underweight, normal weight, overweight, or obese.
“Many healthcare professionals use the body mass index (BMI) for a quick approximation of most people’s health,” he explains. “All you need is the patient’s weight and height, and you can calculate this number.”
There are exceptions, however. “In particular, bodybuilders and other athletes can generate results that make it seem like they aren’t healthy, when in fact they’re in excellent condition,” Padron explains. “That’s because BMI doesn’t consider muscle mass, and muscle is more dense than fat. In addition, BMI doesn’t account for visceral fat being more dangerous than fat deposits elsewhere in the body.”
That’s why Padron cautions people not to make snap judgments based on BMI alone and to seek a more comprehensive view from healthcare professionals. “Factors like body composition, blood markers, and lifestyle need to be considered,” he explains, “which is one of the many reasons why we only offer individualized care at MD Exam.”
If your BMI falls in the overweight or obese categories, then it’s time to make a change. “Unfortunately, excess body weight means you could be developing major health problems that you otherwise wouldn’t,” Padron says. “Being overweight has also been associated with depression. In my experience, it can have a negative impact on self-esteem and even lead to the development of eating disorders.”
Luckily, groundbreaking new drugs have become available to help people recover their quality of life.
How Ozempic and Wegovy can help
According to Padron, pharmaceutical solutions like Ozempic and Wegovy can help most people achieve and sustain a healthy body mass. These medications reduce appetite and increase feelings of fullness, thereby enabling people to regulate their consumption better.
“One of the most important things our patients report is that they’re no longer tormented by cravings,” Padron says. “They find it easier to avoid overeating in the first place.”
In addition, Ozempic and Wegovy have been shown to decrease visceral fat — the dangerous kind of fat deposits. “The idea is to optimize health and well-being, not just lose weight,” Padron says. “We want to make sure you lose the right pounds. When you lose visceral fat and keep muscle, you are heading in the right direction and your body composition improves.”
In some rare cases, however, Ozempic and Wegovy aren’t effective. “Luckily, other interventions can be effective in those cases, such as Tirzepatide or classic weight-loss drugs,” Padron says.
Yet Padron emphasizes that weight-loss drugs alone are insufficient to achieve and sustain a healthy body mass.
Personalized, comprehensive support
“Just taking a pill won’t make pounds disappear,” Padron says. “To lose weight, it’s necessary to get real about your lifestyle and actually change your habits. If you haven’t been exercising, for instance, then it’s time to start getting up a little earlier and going for a morning walk. If you haven’t been eating well, then it’s time to stop buying soda and junk food.”
Easier said than done? “We know it’s hard,” Padron says. “That’s why our program takes support seriously. Our medical staff works with patients one-on-one to develop treatment plans that will work for them. We also provide coaching and connect patients to each other for mutual support and accountability. MD Exam is a community. People make friends for life on our platform.”
Obtaining a healthy body mass often leads to increased energy levels, improved mobility, and reduced joint pain. It can also help control chronic conditions like high blood pressure and sleep apnea, as well as forestall the development of preventable diseases. If that isn’t already enough, it can also boost patients’ self-confidence and mental health.
“Our patients experience an incredible feeling of accomplishment and empowerment,” Padron says. “Losing weight can be truly transformative. I can’t tell you how many people have told me their whole outlook on life has become more positive.”
For Padron, helping people lose weight is its own reward. “I love watching people shed their depression and come back to life,” he says. “This is the most rewarding work I can imagine.”

Kat Marie Alvarez: Where Innovation Meets Regulation
Regulation is often thought of as a limitation, yet in healthcare, it also serves as a foundation for building models that endure. For Kat Marie Alvarez, Founder and CEO of KATALYST & CO, the framework of rules established by agencies like CMS (Centers for Medicare and Medicaid) and the OIG ( office of the Inspector General) create opportunities to design systems that are compliant, ethical, and transformative. Her approach demonstrates that regulation can be a platform for innovation when it is interpreted with both technical rigor and vision.
Kat’s 25-year career reflects this philosophy. A former nurse who advanced into executive leadership and strategy, she has led $2.7B+ P&L operations, advised on over $5B in healthcare transactions, and guided value based organizations including Innovacare, Cano Health, WellMed, Centene, and Humana through periods of exponential scaling. Her perspective combines clinical, financial, and regulatory experience, giving her a unique ability to design structures that support integrity and accountability while driving measurable outcomes.
Turning Statutes into Strategy
For Kat, regulation serves as a framework for building smarter and more ethical models. She interprets CMS guidance and OIG rules as levers for innovation, using them to advance integrity and accountability. With the CMS V28 risk adjustment model, Alvarez refined coding practices, strengthened clinical documentation, and structured risk frameworks that reward accuracy and elevate standards of care. In addressing RADV audits, she crafted strategies that protect stakeholders while keeping patient outcomes at the forefront. She aligns compliance, cost, and care in equal measure. Her current work as a contributor to the CMS IDea Challenge, an initiative focused on strengthening the foundation of trust in our system, further echoes her commitment to advancing regulations in ways that unlock innovation while safeguarding the integrity of care.
Her interpretive approach brings discipline and vision to every challenge. She engages stakeholders to redesign workflows that meet regulatory requirements and enhance the patient experience. Each policy becomes a mechanism to strengthen accountability and operational precision, shaping a system that is both compliant and humane.
Innovation Built Within Boundaries
At KATALYST & CO, this interpretive approach is carried into every project. Kat has integrated predictive analytics and AI-driven tools into care models, with safeguards that ensure interventions remain clinician-led and ethically sound. For example, AI flags in chronic disease management are connected to human-led actions that improve patient care. The result is a model that benefits from technology while preserving accountability and clinical integrity.
Staffing and infrastructure provide another example of her philosophy in action. By leveraging offshore BPO operations in Latin America, Asia, and Eastern Europe, KATALYST & CO extends capacity for health plans and providers. These expansions are carefully designed to meet data security, licensure, and jurisdictional requirements, ensuring that global reach is paired with local compliance. It is a system that balances scale with responsibility.
The Art of Influence Through Alignment
Kat often describes her role as translating complexity into clarity. Whether she is working with payers, providers, or investors, she builds consensus by grounding ambitious strategies in the language of statute. Value-based care models, utilization management programs, and clinical frameworks are designed to prove compliant ROI for stakeholders while maintaining patient focus.
Her approach begins with people. In integrations, partnerships, and platform builds, she respects legacy strengths, listens to frontline voices, and creates systems that are not only efficient but also trusted. This ensures that compliance does not feel like restriction, but like a structure that supports innovation and adoption.
Redefining the Future of Compliance and Care
KATALYST & CO is scaling with $10M in initial funding, expanded international operations, and a growing advisory portfolio. Under Kat’s leadership, the firm is showing how regulation can be a foundation for both innovation and durability. She demonstrates that lasting progress in healthcare is achieved by leaders who know how to design systems that are bold, ethical, and deeply human.
By approaching regulation as a guide rather than a limitation, Kat Alvarez is building models that prove compliance and innovation can move forward together. Her formula ensures that the future of healthcare is shaped not only by ambition, but also by trust and responsibility.
