Retatrutide may become one of the most powerful weight-loss medications ever studied, but more mechanisms do not automatically mean better medicine. Dr. Kathryn Retzler’s take is cautious: do not rush, respect the physiology, and remember that weight loss still needs a clinical system around it.

New research adds to a growing body of evidence that movement, sleep, and less sedentary time are central to brain health. Dementia prevention is not about one supplement or one scan. It is about reducing cumulative risk across the systems that keep the brain resilient.

Some products are marketed as natural, plant-based, or alcohol alternatives, but that does not mean they are safe. Feel Free is a useful example of why supplement marketing needs clinical context, especially when products affect the brain, nervous system, mood, pain, sleep, or dependence pathways.

Birding is more than a quiet hobby. New brain imaging research suggests that expert birders may develop measurable differences in brain regions involved in attention, visual processing, memory, and object recognition. The finding does not prove that birdwatching prevents dementia, but it supports something longevity medicine has long recognized: the brain is shaped by how we use it.

Thyroid peroxidase antibodies can help identify autoimmune thyroid activity, most commonly Hashimoto’s thyroiditis. But a positive TPO antibody test does not automatically mean the thyroid is failing, and a high antibody number is not treated the same way as abnormal thyroid hormone levels. In longevity medicine, TPO antibodies are most useful when interpreted alongside TSH, free T4, free T3, symptoms, family history, pregnancy context, thyroid medication use, and the broader immune and metabolic picture.

Peptides are not one thing. Some are FDA-approved medications with specific indications. Others are compounded, investigational, or marketed as anti-aging injections despite limited safety and outcome data. The distinction matters.

Molecular hydrogen is biologically interesting, and early research suggests possible effects on oxidative stress, inflammation, metabolism, and recovery. But “miracle molecule” claims that promise to reverse aging or chronic disease have moved far ahead of the evidence.

After losing my black German Shepherd, Onyx, to hemangiosarcoma, I found myself thinking about what dogs really do for our health. The science suggests pet ownership, especially dog ownership, may be associated with longer life and lower cardiovascular risk. But the deeper truth is not just about walking more steps. It is about routine, connection, purpose, grief, and the way an animal can become part of our nervous system.

Skin care is not just about looking younger. In longevity medicine, skin reflects UV exposure, collagen remodeling, inflammation, hormones, metabolic health, barrier function, and cancer risk.

Some people experience real symptoms they attribute to Wi-Fi, phones, smart meters, or household electronics. But the scientific question is whether everyday EMF exposure is the cause. In longevity medicine, the answer requires physiology, not fear marketing.

AI-generated health pages, fake doctor accounts, anonymous symptom groups, and miracle wellness funnels are becoming harder to distinguish from real medical guidance. Here is how patients can protect themselves online without becoming cynical, fearful, or disconnected from real care.

Some people with mast-cell symptoms wonder whether Wi-Fi, phones, smart meters, or other electromagnetic fields are triggering their reactions. The biology is plausible enough to study, but the human evidence is not strong enough to call everyday EMF exposure a proven cause of MCAS.
