Fall Thoughts: "98% of All Diets Fail"

There are lots of numbers associated with the idea of trying to change your body size or composition.  The obvious numbers like the number of the scale, your waist measurement, the size of your pants or your body fat percentage. There are the numbers associated with a best guess for how much of what food you should eat, i.e. 800 grams of fruits and vegetables or 13 ounces of protein (at least for a woman of my size.) And there are numbers connected to how you move your body: how many hours you should strive for per day, how many steps you should take, how many reps you should "leave in the tank" during a weight lifting session.  

There are also other numbers, including "the facts."  For example: 80% of Americans aren't eating the recommended amount of fruits and vegetables.  70% of Americans are overweight or obese.  

And, my new favorite fact: "98% of all keto diets fail," which was what Dr. Robert Cywes, the Carb Addiction Doctor, who advocates for a low carb way of eating, stated in his latest YouTube video.   

Is this true? He says it's what he sees in his clinical practice. 

I think it's a commonly accepted truth that "all diets fail."  But, what does that mean, exactly?  
  • Does a diet automatically fail if someone stops following it?  If I said I was going to eat zero candy at Halloween but I ate a bag of M&Ms, does that mean I am now in the diet failure camp?
  • Does a diet fail if you immediately switch from one diet to another? "All diets change" could be a more accurate statement? 
  • Others might think that a diet "fails" when it doesn't create the anticipated result.  But, that's a lot of pressure to put on the "diet." Some people might not implement the diet consistently enough or long enough for the diet to have a chance to succeed.  (The diet is set up to fail from the very start?)
  • Others might think the diet has failed but it actually succeeded.  For example, you've lost zero pounds but your sleep has improved and you have more energy.  
  • For some, perhaps the diet does achieve the original goal but is not sustainable over time.  For example, it lowers your A1C for a few months, but a year later, your numbers are back to pre-diabetic. Is there no credit for partial success? 
  • Maybe "fail" is the wrong term here.  Maybe diets don't fail.  Maybe they pause.  Maybe they end. Maybe they restart.  Maybe they change or spin-off into something a little different. 
  • I feel like making broad statements like "all diets fail" or "only 2% of people keep off the weight they lose long term" is disheartening.  Why start something that you know is going to fail?  
  • It is also interesting to me that we accept that many other items we purchase for daily use in our life will eventually fail.  For example, when I buy a light bulb, I know it has a limited use time.  At some point, it will fail.  But I don't bemoan the fact that "all lightbulbs fail" when I'm contemplating the purchase of a new one.  I might say the light bulb burned out or stopped working but I don't use it as a reason not to buy one (there's a 100% chance this light bulb will fail!) 
If you accept the premise that "all diets fail" but that we have to eat to live, then I guess it's time to reconsider what we mean when we choose how we want to eat and what we want our way of eating to do for us.  If all diets fall, then what's the flip side? What succeeds? What words and concepts need to be redefined before people decide to take the leap and change how they are eating?  An interesting discussion for a future blog, I think! 

What Dr. Cywes Meant* 

In all fairness to Dr. Cywes, I believe the point was trying to make was this: No matter how good a diet is, it is unsustainable unless the "dieter" has also found a way to implement a way to manage their emotions.

VIP Wine Tasting in Del Mar

Yesterday, we had a wonderful time at the VIP Wine Tasting at the Del Mar fair.   Only 250 tickets were sold, and we got to experience several excellent wines with food pairings from Chef Barry, who works at the Turf Club at the Del Mar fairground.   The event started at 12:30, and we arrived early because we weren't sure what traffic would be like, which gave us a chance to learn about the secret destination that would be open later and inspired me to start looking for a wine-tasting shirt for William to wear on our wintery adventures.   What I Wore | Follow The Flamingos I think my favorite (big surprise) was the Chile & Coffee Crusted All Natural Brandt Beef Skirt Steak with Jalapeño Mashed Potatoes,  paired with a 2018 Costa Azul Cab Sauvignon from Alexander Valley.  I also enjoyed some of the sparkling wines, which were paired with cheese made specifically for the event by a local cheesemaker who only makes the cheese in small batches. As part of the VIP exper

Summer Conversations: We Got COVID

Early 2020.  I was filling the role of a Public Information Officer in the Hospital Command Center at our Hillcrest hospital. UC San Diego Health was caring for COVID-positive patients who had recently been flown in from Wuhan, and I was helping write communications to keep our team members up on the latest developments, like what kind of PPE to wear and more.  I would alternate 8-hour shifts with my colleagues, one of many people packed around a conference room table. I remember the unbelievable moment when we went from 4 to 7 positive patients, waiting for COVID test results to arrive from the CDC in Atlanta, the U.S. Marshalls coming to pick up people who had been discharged, and sharing food with the hospitalists and translators who were providing in-person care for the people just a few floors away from me.   You know the rest of the story or at least your own version of it.   I didn't get COVID in 2020.  Or 2021. But I did test positive for it on July 18, 2022.   Yes, William

Summer Thoughts: 20 Days Out

Another one of my family members joined the Rona Club this week, and as I was sharing my experiences of what worked for me, I started thinking about what I knew, what I didn't know, and what I would do differently to care for myself after testing positive.   My goal is to stay healthy all the time and yet,  I do acknowledge that we know that this is not a "one and done" type of situation at this moment in time.   So, I decided to write a letter to my pre-COVID self to help myself out in the future if the need should arise.  (A friend and I recently discussed the fact that we've all been so intent on "not getting it" and wished that we'd better prepared for what to do if we did. If you've had it, what would you do differently?) Dear Future Rachel,  You didn't want to get COVID, but you did.  You hoped to remain asymptomatic, but you didn't.   The virus was annoying, frustrating and exhausting, but it wasn't scary, and you required no speci
