Part I: Monitoring Biomarkers to Reverse Aging: Part II, Diet, CR & Fasting: Part III: Exercise, Protein Part IV: Optimize Nutrients Through Diet Part V: Inhibit CD38 to Optimize NAD Part VI: […]
In the video below, Steve Hill from Lifespan.io and I talk about findings from a recent paper (https://content.iospress.com/articles/journal-of-alzheimers-disease/jad200306) that supports a role for the gut microbiome on Alxheimer’s disease. Check it out!
Meta-analysis for the association between HDL with all-cause mortality risk has identified HDL levels 55 – 60 mg/dL range as optimal. However, that data includes subjects up to 85y-in the video, I present data for 85y – 115yr olds that additionally suggests HDL in the 55 – 60 mg/dL range […]
Animal products, including meat, cheese, and eggs contain carnitine and choline, metabolites that are converted by gut bacteria into TMA, which is then converted by the liver into TMAO. Plasma levels of TMAO are associated with an increased risk of disease and death, so should we limit intake of these […]
A reduced mortality risk and an increased lifespan has been reported for people who have APOE2 alleles, when compared with APOE3 or APOE4, but beyond associations, data for lifespan in APOE-expressing mice was recently reported, evidence that supports a causative role for APOE on longevity.
My latest blood test results are in-how’s my biological age? In the video I discuss my dietary approach prior to my latest blood test, the blood test results, and my plan to improve them with diet going forward.
Calorie restriction (CR) is well known to extend average and maximal lifespan in a variety of animal models, but what about in people? In this video, I present evidence showing that CR slows biological aging, which suggests that CR will positively affect lifespan in people.
After going on Joe Rogan’s podcast, Paul Saladino, MD, posted his show notes, which included his blood test results. Based on that data, is his biological age optimal while on a carnivore diet?
Sleep changes during aging may impact Alzheimer’s disease risk, and with the goal of minimizing that risk, can sleep, in particular, levels of deep sleep, be optimized?
11 epigenetic clocks have been published since 2011, but which is best for predicting aging and age-related disease? In this video, I present findings from a recent publication, “Underlying features of epigenetic aging clocks in vitro and in vivo”, that compared data for 11 epigenetic clocks, and derived a new […]
Here’s a podcast that was recorded with WildHealth, enjoy!
Cooking foods at temperatures higher than boiling produces advanced glycation end (AGE) products, which induce insulin resistance and inflammation, and shorten lifespan in mice. Similar data exists in humans for the effect of dietary AGE products on insulin resistance and inflammation, and a higher dietary AGE product intake is associated […]
Germ-free mice (animals don’t have a microbiome) live longer than microbiome-containing mice, but it’s impractical for people to live in a bubble for their entire lifespan. As a more practical approach, which microbiome-derived factors impact lifespan, and can they be modified? Dietary supplementation with acarbose increases lifespan, and one reason […]
The incidence of fungi bloodstream infections increases during aging-is that a potential explanation for the presence of fungi in the brains of Alzheimer’s disease patients? Rapamycin is a known antifungal-is it effective against fungi that are found in the blood and brain?
Maximal lifespan in calorie restricted (CR) mice can range from 45 – 55 months. In this video, I present data for 3 studies on rapamycin-can it beat CR for maximal lifespan?
On my latest blood test (August 2015), my total cholesterol was 127 mg/dL-is that value optimal for health and longevity? Based on data for 1,104,294 men younger than 60y (median age, 40y) that were followed for up to 14 years (Fulks et al. 2009), my 127 mg/dL value (1 – 2.4%) […]
In order to slow aging, it’s important to know how circulating biomarkers change during aging, and how these biomarkers are associated with risk of death for all causes. In this video, I discuss blood test data for the oldest old, including centenarians (100 – 104y), semi-centenarians (105 – 109y), and […]
LPS increases during aging, which may explain the age-related increase for CD38 and decreased NAD+. LPS is decreased on a calorie restricted diet, but what else can reduce it? In this video, I present evidence for intestinal alkaline phosphatase’s (IAP) role on LPS, and posit that interventions that increase IAP […]
My latest blood test results are in-how’s my biological age? In the video I discuss my dietary approach prior to my latest blood test, the blood test results, and my plan to improve them going forward.
Vitamin K is found in 2 predominant forms, Vitamin K1 (phylloquinone), found almost exclusively in green leafy vegetables, and Vitamin K2 (Menaquinone), found in fermented foods, organ meats, meat, butter and eggs. In the data below (Juanola-Falgarona et al. 2014), we see that Vitamin K1 (phylloquinone) is negatively associated with […]
NR and NMN are popular ways to try to boost levels of NAD+, but that approach hasn’t worked every time in human studies. One reason for that may involve CD38, which degrades both NR and NMN. With the goal of boosting NAD+ levels during aging, why does CD38 increase with […]
Blood urea nitrogen (BUN) is one of the 19 variables found on the biological age calculator, aging.ai. It measures the amount of nitrogen, as contained in urea (i.e., blood urea nitrogen, BUN) in your blood. The reference range for BUN is 5 – 20 mg/dL, but within that range, what’s […]
Consistent exercise training would seem like the obvious choice to reduce resting heart rate (RHR) and to increase heart rate variability (HRV). Are there other factors that can impact these variables? Body weight and daily calorie intake may affect RHR and HRV, and in the video I present 700+ days […]
To determine what’s optimal for resting heart rate and heart rate variability, I review the published literature for how they change during aging, and what’s associated with mortality risk. Also included are my data over the past ~2 years, to see how I compare against the literature.
In an earlier video, I presented data for total cholesterol (TC) levels in blood in terms of changes during aging and all-cause mortality risk. I’ve measured TC 25 times in the past 5 years, and in this video, I present that data, and my approach to optimize it. https://www.youtube.com/watch?v=PBv_hXwUqHM&feature=emb_logo
How much Vitamin C (ascorbic acid) is optimal for health? To answer this question, I’ll examine the association between circulating levels of Vitamin C with all-cause mortality risk. Then, which dietary Vitamin C intake corresponds to optimal plasma levels? Let’s have a look! A variety of studies have investigated associations […]
An adequate daily intake of Vitamin K1 is 120 and 90 micrograms/day for males and females, respectively, but are those amounts optimal for health? In this video, I present evidence that consuming more than 1000 micrograms of Vitamin K1/day may be optimal.
Many interventions have been reported to increase NAD levels, but dietary components that can impact NAD levels are less discussed. Here, I highlight the ability of two dietary components, apigenin and quercetin to increase NAD, and report the foods that contain these metabolites.
Wearing a mask, washing our hands, and social distancing are commonly recommended to slow the spread of SARS-CoV-2 infection. But, what about diet? In this video, I discuss the hypothesis that hesperidin, a metabolite found in lemons, oranges, and peppermint leaves, may contribute to the prevention and treatment of COVID-19. […]
In this video, I discuss data for 6 blood test measurements since 2018 that show a Phenotypic (Biological) Age that is ~14 years than my current age (47y). https://youtu.be/85t8vmIgR6s
What are the blood biomarkers of a centenarian, and is there room for improvement? Find out in the video below! https://www.youtube.com/watch?v=XhCUuxhxmpg
How does the gut microbiome and its metabolic products affect muscle mass, muscle composition, and physical function? In this presentation, I review the evidence, then I present recent data from our group.
Here’s a video clip about my latest Biological Age measurement!
Most often overlooked on a standard blood test are the mean corpuscular volume (MCW) and Red Blood Cell Distribution Width (RDW). How do they change during aging, and what’s associated with all-cause mortality risk? Also, with the goal of optimizing MCV and RDW, how does my diet correlate with these […]
In this relatively short clip, I talk about how serum levels of creatinine change during aging, what levels are associated with risk of death for all causes, and I show my own data for 15+ years! https://www.youtube.com/watch?v=PK6oBMMasFU
Interestingly, we recorded this as I was recovering from a respiratory infection. Was it SARS-CoV-2, or influenza? I’ll know later this week! https://www.bisu.bio/biohacking-to-100-longevity-lessons-from-15-years-of-self-tracking-ft-michael-lustgarten-phd/
In the first 45 minutes, discuss each of the biomarkers contained within Levine’s Biological Age calculator, Phenotypic Age. After that, I answer questions from the audience and we discuss all things related to aging. https://www.youtube.com/watch?v=8hs2n7U7J-k&t=30s
Here’s a recent podcast that was recorded with Julian Hayes II at Optimal Health for Busy Entrepreneurs: https://theartoffitnessandlife.com/episode20/ Enjoy!
CD8+ T cells are a subset of lymphocytes that play a major role in antiviral defense (Kulinski et al. 2013). However, recently published evidence shows reduced levels of circulating CD8+ T cells in people infected with SARS-CoV-2 (Zheng et al. 2020, Wang et al. 2020; HC= healthy controls, NCP = patients with COVID-19 […]
There are a few ways that we can fight the novel coronavirus (SARS-CoV-2). Clinical trials aimed at vaccination have recently begun, and at the earliest, could be available within 6-18 months. Similarly, drugs aimed at inhibiting, blocking, or reducing viral replication, including remdesevir and hydoxychloroquine are entering clinical trials, but […]
Here’s my latest academic publication! https://link.springer.com/article/10.1007/s12603-020-1344-1
Exactly 1 month ago, my first biological age measurement of 2020 was 32.75y (https://michaellustgarten.com/2020/02/14/biological-age-32-75y-chronological-age-47y-first-2020-measurement/). When considering that my chronological age is 47y, that’s a 14 year improvement, but I wasn’t (and still aren’t) satisfied. When I sent my blood for analysis, I was battling a mild upper respiratory infection (cough, […]
In terms of all-cause mortality risk, is the reference range for circulating triglycerides (TG, <150 mg/dL) optimal? A meta-analysis of 38 studies in 360,556 subjects with a median age of 48y and a 12-year follow-up reported lowest all-cause mortality risk for subjects with TG values less than 90 mg/dL (equivalent to ~1 […]
Measurement of biological age with Levine’s Phenotypic Age calculator is strongly correlated with chronological age (r=0.94; see https://michaellustgarten.com/2019/09/09/quantifying-biological-age/). In 2019, I measured all 9 of its analytes 3 times, with biological age readings of 35.39y, 35.58y, and 31.3y, for an average 2019 biological age of 34.09y (see https://michaellustgarten.com/2019/11/01/biological-age-31-3y-chronological-age-46y/). That’s 12 […]
How’s my progress on the road to achieving a resting heart rate (RHR) as close to 40 beats per minute (bpm) as possible? Shown below is my RHR data for August 2018-Jan 2019, which corresponds to the 6-month period after I started tracking RHR. When compared with that period, am […]
A meta-analysis of 10 studies, including 80,139 subjects was recently published that shows a significantly reduced risk of death for all causes in association with higher total dietary fiber intakes (35-39g/day), when compared with lower fiber (Reynolds et al. 2019): Should we supplement with fiber, or get it from […]
Here’s a link to a recent interview, https://biohackstack.com/posts/michael-lustgarten/?fbclid=IwAR059Jf6eT4SyvsqTxHaSir2hQuXKjV5R6kLg-7Df1Kc4c7ZKM6Tw-0qRwY Including: How (and why) did you get involved in research in aging and the human microbiome? How did you get started in health optimization / quantified-self? What are your thoughts on biological age testing? Which tests (epigenetic, blood biomarkers, telomere, etc) and […]
In an earlier post (https://michaellustgarten.com/2019/09/15/drink-green-tea-reduce-and-all-cause-mortality-risk/), I reported that green tea consumption is associated with reduced risk of death for all causes. Now, there’s more recent data! Drinking more than 1 cup of green tea per day is associated with reduced all-cause mortality risk in a pooled analysis of 8 studies […]
