Just in case you haven’t switched over to following the new blog at Pillar PC here’s a link to the newest post.
As many of you know, Trinity Direct Primary Care is changing. I’ve emailed about this several times over the last couple months. Here’s a recap and an update.
Trinity Direct Primary Care (TDPC) is separating from its parent company. The partners of Trinity Medical Associates (TMA), PC have decided to grow in a direction that requires TDPC to be disconnected from TMA. This brings a great opportunity for me and Dr. Hone. We continue to feel led by God to stay within the direct primary care model of practice. It has benefited both our patients and our own lives tremendously.
Therefore, we are individually purchasing out our practices and will soon begin independent operations and ownership. I am continuing at my current location and changing the practice name from Trinity Medical Associates of Hardin Valley to operate under the name Pillar Primary Care, PLLC. You can find information on my practice and the story behind that name at my new website www.pillarpc.com. Lainy and Kristen are continuing on here and I’ve added two new clinical staff, Marci and Mary. Carly is also remaining in her nutritional counseling role. Dr. Hone and I plan to continue to work in a mutually supportive manner the exact nature of which has not been finalized. She is also still finalizing the information on her new location and practice changes but from what I’ve seen so far it’s pretty exciting. We will announce those as soon as the details are settled.
With a new practice name some of our contact points will change but most stay the same. Our office address remains the same as does our office phone numbers. Feel free to call us at 865-244-1800 or fax at 865-444-6002 anytime if we can help.
My new email address is email@example.com. Lainy can be reached at firstname.lastname@example.org. Our nursing staff of Kristen and Mary will share the email email@example.com so that they are always available for your emails as needed. Marci Wood, FNP, our new advanced practice nurse practitioner, is available at firstname.lastname@example.org. The old email addresses will auto respond with this information if you accidentally email them.
Marci and Mary staff the clinic on Thursdays so that patients can be seen five days a week. I expect us to need them here more days of the week too as we continue to run a monthly waiting list of new patients that would like to join the program. I have also been approached by another large local organization looking to offer DPC for their employees. The DPC trend is exploding!
Lastly, the new Pillar Primary Care Facebook page is www.facebook.com/pillarpc.
On Call Contact
One change that is both challenging and rewarding is the change of after hours coverage. Once the official separation date is set (it has not been fixed yet as there is a lot of legal work that must be done to disentangle 13 years of joint ownership for me) I will no longer participate in the Trinity call rotation. Therefore, as much as I am able, I will be on call for my patients every day. Generally, I’ll be able to respond to patients who contact me before 5pm each scheduled work day. After 5pm, I’ll follow up the next business day for non-urgent issues and as soon as possible for other issues. Many of you know I respond to non-urgent emails after hours already. That’s likely to continue, but I’m trying to have good boundaries for my work and home lives. Since I really love what I do, it’s a challenge, but my first love remains my family and time with them.
As much as I love my work, it’s simply not possible for one person to be available 24/7. Many of my hobbies take me outside of cell phone range for a time, so there may be circumstances in which I’m not available and patients will need to seek care outside of the membership program in order to address their need in a timely manner. As we grow and add more clinical staff, I expect these circumstance to be even more uncommon. For now and in the future, feel free to contact the office at 865-244-1800 to be directed to the best option for your care either during or after scheduled work hours.
As to vacation, I will continue to take a few weeks each year away with my family. These will most often coincide with Knox County school’s Fall and Spring Breaks and two weeks in the summer. After the separation from Trinity Medical Associates, the walk in clinic will not be available as part of membership services when I’m out of the office. It remains, in my opinion, the best walk in clinic in the region and patients are welcome to seek care there at a very affordable cash rate or utilize their insurance, but it will not be covered by the membership program.
I hope all these shifts, changes, and improvements fill you with the same sense of excitement as they do me. I’m very thankful to the support of my patients over the years and God’s clear provision and guidance to build this program. Please feel free to contact me directly with questions.
What can’t you get at Walmart?
Apparently nothing. The retail giant has begun opening retail medical clinics in major metropolitan areas with the expectation that more Americans are going to need access to primary care services.
The retailers see 10,000 baby boomers aging into Medicare coverage each dayWalmart’s First Healthcare Super Center Opens
To their credit they do offer a more transparent pricing scheme for services with an asterisk disclaimer stating that the final price of services is dependent on what services are rendered. Certainly the list of labs prices I’ve seen offers standard labs at 4-5x their wholesale price. These are labs we offer free in our practice, by the way.
Additionally, they limit their services to patients older than 18 months of age. That’s pretty typical of retail clinics. I’m sorry/not-sorry for my sarcasm, but retail clinics want to help but only if it’s easy. They aren’t there to actually develop a long term relationship with a patient who needs care over the various seasons of their life. Retail clinics are the definition of vending machine medicine.
Given what I’ve personally experienced trying to get routine medications filled at Walmart, I’m not excited about the prospect of my mother having to get her Medicare annual wellness exams done there. For the sake of all those patients who need a skilled physician to walk with them through the difficult moments of their lives, I hope my pessimism is proven wrong.
Posted below are two reports generated from the Freestyle Libre LibreView website. They show the average relative change in my blood glucose with each meal of the day. The first report was during the high carb, standard American diet experiment in July. The second report is from the nutritional ketosis diet I just blogged about and am still following. I think it is readily apparent the differences. In the high carb diet I would jump 20-30 mg/dL every time I ate and I averaged 30-80 gms of carbs per meal at least. With nutritional ketosis the glucose changed less than 10 mg/dL with each meal and I only averaged 6gms of carbs per meal.
Over the last week I’ve documented my progress into nutritional ketosis through a ketogenic diet. Yesterday, I added intermittent fasting to that process. Here are the results.
As most of you know, I have advocated for low carb high fat nutrition to reverse metabolic disease since I began practicing it myself in 1999. My understanding of this powerful tool has grown both with my personal experience of it and with the growing body of literature helping to explain the nuances we should all understand. Over the last three years intermittent fasting (IF) has come into it’s own in large part due to the influence of Jason Fung, MD author of The Obesity Code and The Diabetes Code, both books I highly recommend to my patients. I have adopted IF as a personal routine over the last year and have found it extraordinarily powerful at improving my health and well-being.
There are many different ways to undertake fasting ranging from time restricted eating (TRE) to prolonged fasts. TRE is simply not eating for about 12 hours in every 24 hour cycle such as not eating after dinner until breakfast the next day roughly 12 hours apart (8pm to 8am). Most studies don’t consider this true fasting as many of the genes and benefits of fasting are not measurable until one reaches 14-16 hours of fasting.
Intermittent fasting therefore is usually anything lasting 16 hours or longer with the remaining hours used as an opportunity to feed. A 16:8 protocol is nothing after dinner at 8pm until noon the next day. A 20:4 protocol is nothing between 8pm and 4pm the next day. I recommend many of my patients undertake a 24 hour fast weekly or every fourth day depending on the goal. Again, I stress, please don’t undertake this without talking to me first as many times patients need their medications reduced or altered to avoid being over treated during the fasted state.
Yesterday I undertook a 24 hour fast which ended up lasting 27 hours due to the timing of my dinner meals on Monday and Tuesday. Monday night I ate a quick meal of roasted chicken, blueberries, and macadamia nuts then went to exercise around 5:30pm. I didn’t eat again until Tuesday night at 8:30pm. Tuesday’s dinner of 1/2 of chicken, an avocado, and cheese was 5 net carbs.
Throughout the day I followed my glucose levels on my Libre and my blood ketone levels on my KetoMojo meter. As you can see from the Libre readings below, my glucose levels were exceedingly stable and slowly declined throughout the day to a nadir of about 69 mg/dL right before dinner. My meal didn’t budge that number at all.
The ketone readings steadily climbed to some very nice levels throughout the day and have stayed higher than last week even after I’ve eaten several times today. Starting out the day at 1.0 mmol/L they climbed to 1.7 mmol/L by lunch time, 2.7 mmol/L by the end of work, and 3.1 mmol/L by the time I broke the fast at dinner.
Beneficial ketone zones after an overnight fast should be around 0.5 mmol/L or higher. They are are optimal around 1.5-2 mmol/L while eating a long term ketogenic diet. After a prolonged fast they can be around 3-5 mmol/L.
When I fast I tend to feel better and better as the day progresses. The initial hours can be challenging but as the ketones develop the desire for food all but fades to zero and hunger is non-existent. I really enjoy that freedom. The clarity of thought and presence of mind that comes in this state is one of the main benefits I desire from fasting. It brings me back to it again and again and I find myself looking forward to the next day of fasting.
If you’re interested in learning how to use nutritional ketosis, intermittent fasting, or a continuous glucose monitor for its health benefits give me a call. We’ll walk through the process together to ensure your success and safety.
I didn’t get a chance to update the daily posts yesterday as the start of school, high school sports practice, and school supply shopping made for a long day. Regardless, the data hasn’t changed much. I had about 29 net carbs Sunday and 22 net carbs Monday.
This produced very stable blood sugar results as shown below.
The spike on August 4th around noon was due to some heavy outdoor work I was cutting down another storm blown tree. The following trend down into the red zone (again not dangerous) was a recovery period. To a degree this is repeated on August 5th at 6pm where I worked out hiking the Hardin Valley hill. During exercise my glucose climbed and then right afterwards it dipped again. That’s an interesting phenomenon that I’m going to have to study more. It happens more often with outdoor exercise than indoor exercise. Maybe the body heat, sweat, and evaporation have something to do with it. This is a good reminder that not all causes of glucose elevation are to be avoided or are harmful. As the body works it wants to fuel the cells and will send glucose out to do that.
My last meal of the day was at 5:30pm yesterday which was some roasted chicken, blueberries, and macadamia nuts. Then I started my 24 hour fast. I’ve tried to incorporate a 24 hour fast into my weekly routine starting Monday after dinner until Tuesday dinner. For various reasons this is the day I’m least likely to eat with my family so giving up a meal doesn’t usually impact our time together. As I write this I just finished up today’s only meal so the fast ended up lasting about 27 hours. I have to say I feel focused and calm more than normal and I have the ketones to prove it. I’ll tell you more about that tomorrow.
So after one week of ketogenic nutrition with daily net carb intake averaging 19.6 gms per day this morning’s ketone level was a solid 1.0 mmol/L. I hope that one week journey into nutritional ketosis show just how straightforward it can be and how it can be implemented in a very busy life.
Tomorrow I’ll share with you my ketone levels throughout a day of fasting. Stay tuned.
Low carb nutrition prompted a 20 lb weight loss along with a reduction in blood pressure even after they had a 20% reduction in medication in these 154 diabetic and insulin resistant individuals that was sustained over two years on average.
: Hypertension is the second biggest known global risk factor for disease after poor diet; perhaps lifestyle interventions are underutilized? In a previous small pilot study, it was found that a low carbohydrate diet was associated with significant improvements in blood pressure, weight, ‘deprescribing’ of medications and lipid profiles. We were interested to investigate if these results would be replicated in a larger study based in ‘real world’ GP practice. 154 patients with type 2 diabetes or impaired glucose tolerance were recruited into an observational cohort study in primary care. The effects of a low carbohydrate diet sustained for an average of two years (interquartile range 10–32 months) on cardiovascular risk factors were examined. Results demonstrate significant and substantial reductions in blood pressure (mean reduction of systolic BP 10.9 mmHg (interquartile range 0–22 mmHg) (p < 0.0001), mean reduction in diastolic BP 6.3 mmHg (interquartile range 0–12.8 mmHg) (p < 0.0001) and mean weight reduction of 9.5 Kg (interquartile range 5–13 Kg) (p < 0.0001) together with marked improvement in lipid profiles. This occurred despite a 20% reduction in anti-hypertensive medications. This novel and potentially highly effective dietary modification, done very cheaply alongside routine care, offers hope that should be tested in a large prospective trial.
Saturday was day 5 of my journey journaling nutritional ketosis for my patients. It was a pretty busy day where I staffed Trinity’s walk-in clinic and then had lots of home chores to get to before school starts next week for the kids.
Breakfast was three eggs fried in ghee and a half dozen chicken sausages from Jones Farms that I’ve been meaning to try. I found these breakfast sausages at Costco a while ago and they looked like a pretty good option for a fast low carb breakfast. They tasted fair but not outstanding, too herby for me. So, they’ll probably stay on the grocery list for when I need something quick to get out the door but, despite the name, I won’t be jonesing for them. Breakfast yielded a net carb of 1.1gms.
During medical school and residency after a long night of call in the hospital, some of the best attendings would show up at morning rounds with a nice treat like bagels or donuts. In that tradition, I’m very appreciative of the team at Trinity and the exceptional fellow clinicians with whom I work that do most of the heavy lifting during our Saturday clinics. As such, I bring fruit, yogurt, and lower carb granola as a treat for everyone. While working I ate a Fage 2% plain yogurt and a 1/4 cup of blueberries. I’ve shown before that too many blueberries, which I love, can elevate my glucose so I had to resist the temptation to eat all of them. This time around there wasn’t much of a bump in my readings. The net carbs for the yogurt and berries was about 9 gms. Again, that’s if the carbs in plain, unsweetened yogurt need to be fully counted. The process of making yogurt uses up some of the sugars in milk.
I didn’t finish up work until mid afternoon so didn’t get to eat lunch until after 3pm. My ketone levels were solid at 0.9 mmol/L though. Same as post overnight fasting. That’s a really good mid day number for me.
For lunch I finished off the brisket along with an avocado and 2 oz of macadamia nuts. Net carbs were 7 gms. After lunch I went to work out at VitalSigns with my daughter. Interestingly, after an hour of cardio and strength work, my ketones actually went down a little to 0.7 mmol/L.
Dinner was a ribeye. Seriously, just 8 ounces of a deliciously marinaded ribeye. Net carbs were under 1 gm. It was a very satisfying meal.
The day’s total net carbs were right at 20 gms with a robust amount of fat and protein too. My glucose readings for the day were static under 100 mg/dL the whole time. This day produced an overnight fasted ketone level of 0.7 mmol/L.Tomorrow, when I write the entry about today’s journey (how timey-wimey), I’ll share with you what caused my glucose to bump over 100mg/dL and why I’m not worried about it.
I wanted to share this week’s email from Peter Attia, MD. It’s a fascinating read about the protective benefits of extreme fasting in mice when they were subjected to a lethal dose of radiation. As he notes in his writing, what happens in mice cannot be directly translated to humans. We’re different species but it helps us develop theories and experiments (that don’t involve lethal radiation) that might prove benefit in humans.
I recently came across an interesting study pertaining to fasting (in mice). The rodents were randomized to ad libitum (i.e., without restriction) feeding or ad libitum feeding followed by 24 hours of fasting prior to the, ahem, “intervention.” Said mice collectively had the privilege of getting blasted with total abdominal radiation at a mega-dose of 11.5 Gy (a unit of ionizing radiation dose) in a single fraction. To get some sense of context here, a CT scan of the abdomen and the pelvis exposes an individual to a relatively high radiation dose, clocking in at approximately 20 milligrays, or mGy (0.020 Gy). This means that for the mice in this study, the absorbed dose of radiation was about the equivalent of 575 abdominal CT scans in one shot.
The average American living at sea level absorbs about 3-5 mGy of radiation annually. So the dose used in the study is almost 3000 times the radiation a person is typically exposed to (and absorbs) over the course of a year.
It therefore might not come as a shock that the non-fasting mice all died within a week from radiation-induced toxicity, akin to humans who have been exposed to staggering doses of radiation (e.g., Hiroshima, Nagasaki, Chernobyl). However, all of the mice that fasted for 24 hours prior to the radiation insult were alive after one month. And while all of the mice, in both groups, showed signs of radiation toxicity, the fasted mice were back to their baseline activity levels 8 days later. The fasting also appeared to protect intestinal stem cells: intestinal epithelial cells in the fasting mice were regenerating by day 10 post-radiation.
The purpose of the study was to find out if fasting could protect the intestines from high-dose radiation, which could allow for higher doses of radiation treatment in killing pancreatic tumor cells. (When patients undergo abdominal radiation the intestines are, due to their rapid turnover of cells that make up the lining, very sensitive to the dose of radiation, and patients are often debilitated by colitis-like symptoms.) Not only did the investigators demonstrate that fasting improved survival and intestinal cell regeneration, they also found that fasting improved the survival of mice with pancreatic tumors also subjected to lethal doses of abdominal radiation. The investigators also noted that the protection conferred by fasting applied only to the normal tissues, whereas the pancreatic tumors were not radioprotected, and actually may have been more vulnerable as a result of the 24-hour fast.
This is not the first time that fasting and/or dietary restriction has been shown to improve the tolerability of toxic cancer therapies (e.g., chemotherapy, radiation therapy). A 2019 review points to several studies in which forms of fasting protects normal cells in mice from the damage induced by chemotherapy and other toxic drugs while differentially making cancer cells more vulnerable.
Of course, what’s true in mice living in laboratory conditions may not be true in men and women living in the real world. I’m doubtful that the study above swung the door wide open for an IRB to approve a clinical trial in humans that includes a lethal dose of radiation. However, fasting is an entirely different story. There already have been a number of feasibility studies in cancer patients showing it is well-tolerated and efficacious.
It’s also worth reiterating (as I try to do every time I make a comment about fasting rodents) that the 24-hour fast in the study above resulted in a 20% loss of body weight. Not a typo. This is about the equivalent of an individual starting a fast this evening weighing 180 lb and dropping 36 lb by the next night. For context, each quarter when I fast for about 7 days, my weight typical goes from about 178 lb to 172 lb or so. (I covered this issue in a little more detail in a previous email.) A 7-day fast is almost universally fatal in mice. In other words, fasting is riskier in mice and generally better tolerated in humans. On the other side of the coin, there is still the question of whether the dose makes the antidote. If a mouse fasts for 24 hours and loses 20% of its body weight, it’s probably not an unreasonable assumption that an equivalent fast for a human is closer to 3 or 4 weeks. (Although, given such dramatic differences, it’s really difficult to say with any confidence if there is a truly equivalent dose of fasting between mice and humans.) Given that the mice in the study received a lethal dose of radiation and survived beyond expectations, could less fasting have sufficed if a more clinically appropriate radiation was given?
That said, given the mounting evidence that fasting appears to be safe and may be beneficial, I would love to see more clinical trials in cancer patients looking at its potential effects, especially given that humans might not need a fraction of the protection the mice needed to survive this study, even under all but the most extreme circumstances.
