When you eat may matter almost as much as what you eat. A population-based study of over 7,000 Spanish adults published in the International Journal of Behavioral Nutrition and Physical Activity found that a later time of first meal was associated with a higher BMI, while a longer overnight fasting duration was associated with a lower BMI. These associations held after adjusting for total calorie intake, Mediterranean diet adherence, sleep quality, and physical activity, meaning the timing effect was independent of diet quality and calories. The relationship was particularly strong in premenopausal women, and a five-year longitudinal follow-up confirmed the pattern. Notably, the benefit of extended overnight fasting was most pronounced for people who had their first meal after 8:30 a.m., suggesting that late-eating patterns carry the most metabolic disruption and have the most to gain from shifting earlier. Meal timing is an underappreciated lever, and it's free. If you're working on weight management, shifting your first meal earlier and extending the gap between dinner and breakfast are practical starting points worth trying.

If you spend most of your day sitting and you're wondering where to start with your health, this study offers a direct and encouraging answer: walk. A large prospective analysis of over 72,000 UK adults published in the British Journal of Sports Medicine found that 9,000 to 10,500 daily steps was associated with the lowest risk of all-cause mortality and cardiovascular disease, independent of how much time participants spent sitting. What's most notable for anyone with a sedentary lifestyle is that people who sat the most (more than 10.5 hours per day) got a stronger mortality benefit from accumulating those same steps, compared to those who sat less. Even 4,000 to 4,500 steps per day was associated with roughly half the maximum benefit, so you don't have to hit 10,000 steps for it to matter. I've argued for years that the single most important thing a sedentary person can do is start walking. It doesn't have to be a formal exercise program or a major commitment. Walking provides substantial benefits on its own, and for many people it also builds the motivation to do more from there.

How many of these did you eat this week? • Liver • Kidney • Heart • Bone marrow • Spleen For 99.9% of people... the answer is ZERO. Because people are eating more calories than ever, yet starving for actual nutrients. Just look at beef liver – a single ounce contains more vitamin A than 10 cups of carrots. And it's in the retinol form your body can actually use, not the plant beta-carotene that converts at rates as low as 3% in many people. The answer lies in what we're MISSING, not what we're adding. Our ancestors didn't obsess over nutrition labels… But they instinctively ate in a way that provided complete nourishment – consuming the WHOLE animal, especially the nutrient-dense organs. These organs contain unique compounds that often don't exist in meaningful amounts in muscle meat or plants. For example, beef heart contains 30-40 times more CoQ10 than muscle meat – a critical compound for cellular energy production that naturally declines as we age. No plant food contains meaningful amounts of this vital nutrient. Organs aren't a fad.

I’ve seen A LOT of discussion on peptides recently. This is a broad topic with lots of different classes of peptides. There are lots of nuances involved in this new modality but I'll share a few thoughts. I want to preface this by saying that we DO peptide therapy at the office. However, we we do it proper care, follow up and caution. We go case by case and determine if you need it or not. There are a lot of people talking about the benefits of peptides and these molecules are being hailed as a fountain of youth. While I do appreciate the unique benefits that peptides can have, I’m also concerned about side effects that I do not see being discussed and long term issues that we do not fully understand at this point. - Peptides are synthetic signaling molecules -- most require injection because your gut destroys them (however, we use liposomal, sublingual peptides that bypass the gut and do not require injection). - For people trapped in severe obesity or metabolic dysfunction, GLP-1s can be a genuine lifeline -- breaking a cycle that diet alone couldn’t crack and reducing cardiovascular risk. - The science of incretin signaling, driven by GLP-1s, has taught us more about satiety than anything in the last 50 years - Some peptides like BPC-157 show real promise for acute injury recovery in animal models -- but the human evidence is almost nonexistent - The trade-offs are real: up to 40% of weight lost on GLP-1s may be muscle, stopping means rapid regain, and the drug class is escalating -- from single to dual to triple receptor agonists -- each more potent, each less understood long-term - BPC-157 and TB-500 ("the Wolverine stack") promote blood vessel growth through the same pathway active in half of all human cancers. Almost zero human data - Growth hormone secretagogues can worsen insulin resistance and elevate cancer-linked IGF-1 - Melanotan crosses the blood-brain barrier and has been linked to melanoma in case reports - The biggest concern: these drugs treat the symptom without addressing the root cause -- and none of them replace what food, sunlight, sleep, and movement can do.

Most research on vitamin D and dementia has looked at people already in their 60s or 70s. A new study from the Framingham Heart Study, published in Neurology Open Access, asked a more consequential question: does your vitamin D level in your 30s and 40s affect your risk of Alzheimer's disease decades later? Among 793 dementia-free adults with an average age of 39, those with higher blood vitamin D levels showed significantly less accumulation of tau on brain scans conducted an average of 16 years later. Tau is a protein that misfolds and builds up in the brain in Alzheimer's disease, and it tends to accumulate in the brain's memory regions well before symptoms appear. The biology behind the link is plausible: the memory centers of the brain are packed with vitamin D receptors, and low vitamin D appears to trigger a chain reaction that accelerates abnormal tau buildup. This adds to an overwhelming body of evidence on vitamin D's importance for long-term brain health and reinforces the value of monitoring your levels before problems emerge. Optimum blood level should be around 70-80.
