A story for a Friday afternoon. Spoiler, I really don't know what to do with it.

So I have this patient. He is mid-50's & healthy aside from an ACS event a few years ago for which he was stented & is on all the right 2ndry prevention things. He is also very active He wears an Apple Watch, & a couple of years ago the watch was telling him he had Afib. Given his CAD, this was important as it would mean adding a DOAC to his regimen which of course does not come without risk.

The watch continued to trigger frequent AF alerts and we did a Zio

I don’t understand why people are so bothered by the fact that metabolic disease can be treated by medicines. It’s not that lifestyle solutions can’t work; they can! It’s that they don’t work for a very large number of people… We should celebrate that more people have solutions that can work for them. Not doing so is the height of arrogance

Anyone else finding it increasingly difficult to tweet anything that does not feel like it is a massive cry for attention? I am overwhelmed by my own self-consciousness here and honestly it is a new phenomenon

Here’s a question for @nicknorwitz & @realDaveFeldman: if I understand, your model hypothesizes that increased ApoB in lean/athletic people on low carbohydrate or ketogenic diets does not result from either 1) saturated fat or 2) genetic variation, but rather from CHO restriction So in the spirit of n=1 case studies, I have one for you. 52 year old male cardiologist BMI 21, exercises 6 days a week, on low SFA ketogenic diet for 4+ years with ApoB ~80 mg/dl

It's been a while since I've bragged on Ruthie so if you're not into that kind of thing just mute me.

Meanwhile, during the pandemic, since basketball was a challenge, she took up crew. She got waaaay into it and very nearly quit basketball as a result But she ultimately decided to play for her high school, where she's now a 9th grader. The girls' varsity basketball team is definitely in a rebuilding phase. They have really struggled, but they've also worked hard, and they do keep getting better (which is all you can ask)

If I understand correctly, one of the core tenets of the CIM is that fat gets trapped inside fat cells which leads to "internal starvation" and this causes overeating & obesity (and associated metabolic disease(s)) One of the things that has bothered me for a long time is that metabolic disease is actually associated with *inadequate* fat storage in fat cells. diabetes.diabetesjournals.org/content/51/9/2…

It is shocking that democracy survived the totalitarianism brought on by seat belt laws now 30 years ago freep.com/story/money/ca… I mean I am still not sure how to explain to my children that the people did not take to the streets over the intrusion of the government into our lives. That constant beeping reminder to buckle your seat belt is practically waterboarding

When does "potentially" become "absolutely 100% definitely certainly"? Of course anyone raised in the '70s and '80s will remember these genius ads:

"when it absolutely, positively has to be there overnight"

Dave, I think we have beaten this topic to a pulp but lest anyone think I am insane or just being a mean bully, I wanted to remind you of this discussion we had over 2 years ago. It is a long thread and related to a podcast you did with Dr. Drew Here is the thread:

And here are screenshots of the relevant parts

Long thread on some new research. Sorry it is long and sorry it's about nutrition. Also I do some speculating at the end... New from outstanding team @UBC including @DrJonLittle @kaja_falkenhain @theloctor + @Dy1anLowe: a randomized trial comparing @ww_us or @getkeyto with weight loss at 12 weeks as primary endpoint:

I guess I graduated from medical school 25 years ago. It got me thinking about what’s changed & what hasn’t.

In the past 25 years in medicine:

1) What has changed that you never expected to change?

2) What hasn’t changed that you expected would by now? I’ll start:

There are some obvious ones like communication. Cell phones barely existed in 1996. Email was just getting traction. Pagers were ubiquitous. We interacted with paper charts way more than we ever touched a computer. Video visits were some kind of Star Trek concept

Quick thoughts on the idea of there being a choice between lockdowns and dead bodies. I live in San Francisco. We had our first COVID cases here in early February. We have been conservative here, but hardly locked down. Restaurants have been open for outdoor dining. Bars now too Gyms and salons recently reopened. Many workplaces are back at less than 100% capacity. Public schools have been closed but private schools have been opening since September

4 years ago I was over-confident but nervous. Today I am just excited Here is a thread from later in the day. It is interesting to see how the potential of Donald Trump as President was just a sick joke at that time. We now have the reality of the past 4 years. We will never get them back...

I've done a number of interviews this week about TREAT jamanetwork.com/journals/jamai….

One of the most frequent questions I get asked is:

"How do you explain that time-restricted eating worked for all those celebrities?"

I'm dead serious that I've been asked this (several times) I usually remind the interviewer that TRE worked for me. I lost weight. But then I also remind that people tend to lose weight (in the short-term) doing a lot of things. It is one of the reasons we do randomized trials

1/ Today is Yom Kippur. Many Jewish people are fasting. I am not

But I still want to talk about fasting… 2/ Today we are finally publishing the results of a study on Time Restricted Eating (TRE), which is a form of intermittent fasting. The study is called the TREAT Study. More on that later…
