[Updated] Longevity Medicine Beyond the Messenger
Originally published November 4, 2025. Updated February 2026. As clinicians and scientists, we often engage with ideas, frameworks, and data that are communicated through books, podcasts, or public figures. It is critical to be clear about where our professional endorsement begins and ends. This article reflects a review of the scientific concepts presented in Outlive: The Science and Art of Longevity. It does not represent support for, or alignment with, the personal actions or conduct of Dr. Peter Attia. Recent reporting has raised serious ethical concerns, and I want to state clearly that I do not condone or excuse any…

What Are Peptides and Why Is Everyone Talking About Them?
In keeping with the latest viral TikTok trends, I couldn’t help but notice the surge of content tagged with #peptides. This isn’t simply encouragement to eat more protein-rich foods like meat, fish, or eggs. Instead, the conversation has shifted toward pills, powders, tinctures, and even injections of various peptides, many of which were never covered in my dietetics training. Naturally, that raised questions. If we’re not talking about the peptides that come from whole foods, what exactly are people taking? I dug into the literature to better understand what peptides are, how they’re being used, and what we actually know…

Is Full-Fat Dairy Back on the Table?
I’d be lying if I said the thought of drinking milk didn’t make my stomach grumble, and not in a good way. Admittedly, I’m one of the growing number of Americans who has mostly phased dairy out of my routine (for the comfort of myself and those around me; if you know, you know). But that doesn’t mean I haven’t noticed the rising trend of full-fat dairy products popping up on store shelves and social feeds. After what feels like decades of low-fat everything, including yogurt, dips, buttery spreads, and salad dressings, we seem to have come full circle, welcoming…

The Weight of the Nation: Insights from the Global Health Data Exchange
A recent article published in The Lancet highlights the concerning status of overweight and obesity in the United States, providing a stark look at the trajectory of this public health crisis. Not only are the numbers projected to rise, but the data also underscores a troubling reality: efforts to combat overweight and obesity over the past 30 years have been largely ineffective. I’m no public health expert, but this clearly calls for a critical reassessment of current strategies and the adoption of a more comprehensive approach. Could this study be the wake-up call we need? Study Overview and Data Analysis…

Are “Forever Chemicals” Really Forever?
I’d be lying if I said I thought much about the chemicals in my food or cookware. If they’re on the market in the U.S., they must be safe, right? But now, with a toddler at home, I feel a strong obligation to consider these health concerns—especially regarding PFAS, or per- and polyfluoroalkyl substances. What are these “forever chemicals”? How do they end up in my food? Should I be worried, and what can I realistically do? If you’ve had similar questions, let’s take a closer look at some of these recent health claims and explore practical strategies to reduce…

Macronutrients and Aging
A recent study revealed that macronutrients, particularly protein intake during midlife, are linked to enhanced brain function in older age. This underscores the long-term impact of dietary choices on cognitive health and reinforces the importance of a balanced diet throughout the lifespan. How do Macronutrients Affect Brain Health? Carbohydrate, fat, and protein play distinct roles in promoting overall brain health. Carbohydrate is broken down into glucose, which serves as the brain’s primary fuel source. Opting for complex carbs like whole grains, fruits, and vegetables ensures a steady energy supply, supporting optimal cognitive function. Individuals transitioning to a lower-carb diet may…

Misconceptions About Immune Health
Our immune health is closely linked to our body’s capacity to fend off germs and bacteria. A robust immune system can effectively shield us from foreign invaders. Chronic illnesses, stress, specific medications, and life stage transitions (such as pregnancy) can compromise our immune health, rendering us more susceptible to common viral infections. Diabetes and Immune Health Diabetes can weaken the immune system, increasing the risk of infections and impairing wound healing. High blood sugars interfere with immune cell function, leading to a higher susceptibility to bacterial, viral, and fungal infections. Chronic inflammation in diabetes further compromises immune health. Proper management,…

Behavior Change and New Habits
As the new year begins, many people start new diets to improve their health. After a month or so, they often feel frustrated and find it tough to stick to these eating behaviors. This can lead to a sense of wanting to give up, even though they haven’t given themselves enough time to develop these new routines. How Long Does it Take to Form New Habits? The speed at which new habits form hinges on our willingness to embrace change. Initially, we assess how our actions align with our short and long-term health objectives. We weigh the advantages of maintaining…

Prenatal Vitamins Beyond Pregnancy
I am frequently asked about prenatal vitamins by my pre- and postpartum clients. Both the American College of Obstetrics and Gynecology (ACOG) and the Academy of Nutrition and Dietetics (AND) recommend using prenatal vitamins during preconception, throughout pregnancy, and during lactation—whether nursing or pumping. Occasionally, I encounter clients who continue taking prenatal vitamins long after their baby has weaned. I caution against this practice because our nutritional needs are distinct during pregnancy. Instead, I recommend considering either a multivitamin or supplementing with specific nutrients as needed. What are Prenatal Vitamins? Prenatal vitamins are tailored to meet the unique needs of…
