Top 10 Videos in 2019 arises from my annual review of the medical literature. With the help of a team of hundreds of volunteers, we churned through tens of thousands of papers published in the peer-reviewed scientific nutrition literature and are ramping up to break new records in 2020. How do I choose which studies to highlight? In general, I strive to focus on the most groundbreaking, interesting, and useful findings; but which topics resonate the most? The practical ones, offering cooking or shopping tips? Or those that dissect the studies behind the headlines? Maybe it’s the geeky science ones exploring the wonderfully weird world of human biology? As you can see from the below list, the answer seems to be a bit of all of the above:

#10 Time-Restricted Eating Put to the Test

Time-Restricted Eating Put to the TestI was so excited to start to put all my intermittent fasting videos up. This one was more of a backgrounder. The thrilling conclusion can be found in The Benefits of Early Time-Restricted Eating, a video that ended up changing my own family’s eating habits.


#9 Eggs & Breast Cancer

eggs and breast cancerHow few eggs should we eat to reduce the risk of prostate, ovarian, colon, and breast cancer?  This was part two of a three-part video series. The others were Dietary Cholesterol & Cancer and Oxidized Cholesterol 27HC May Explain 3 Breast Cancer Mysteries.


#8 Is It Best to Drink Tap, Filtered, or Bottled Water?

Is It Best to Drink Tap, Filtered, or Bottled Water?When I was writing the hydration chapter in How Not to Diet I figured I should do a deep dive into the best water filtration system. Given the disinfection byproducts in tap water, Brita, PUR, ZeroWater, and refrigerator water filters are put to the test. 


#7 Is Butter Really Back? What the Science Says

Is Butter Really Back? What the Science SaysYears ago I tried to put the controversy to rest with my videos The Saturated Fat Studies: Set Up to Fail and The Saturated Fat Studies: Buttering Up the Public but it keeps rearing it’s buttery head.


#6 Kidney Stones and Spinach, Chard, and Beet Greens: Don’t Eat Too Much

Kidney Stones and Spinach, Chard, and Beet Greens Don’t Eat Too MuchGiven their oxalate content, how much is too much spinach, chard, beet greens, chaga mushroom powder, almonds, cashews, star fruit, and instant tea? Wait, what are oxalates? You may want to also check out the prequel video Oxalates in Spinach and Kidney Stones: Should We Be Concerned?

#5 The Best Diet for Diabetes

The Best Diet for DiabetesThe case for using a plant-based diet to reduce the burden of diabetes has never been stronger and the good news is that finally the guidelines are starting to catch up: Plant-Based Diets Recognized by Diabetes Associations.


#4 Which Is a Better Breakfast: Cereal or Oatmeal?

Which Is a Better Breakfast, Cereal or Oatmeal?One of the things I learned while writing How Not to Diet was the importance of not just whole grains but intact whole grains, the remarkable impact of the structure of food beyond nutritional content or composition.


#3 How to Cook Greens

How to Cook GreensDark green leafy vegetables are the most nutrient-dense foods on the planet. What’s the best way to prepare them? What about other vegetables? Another popular video this year was Best Way to Cook Vegetables.


#2 Keto Diet Theory Put to the Test

Keto-Diet-Theory-Put-to-the-Test-1Multiple videos from my ketogenic diet series made the top 10, but I decided to just list one, but you can find the rest here!



#1 Evidence-Based Weight Loss

Evidence Based Weight LossEven though this just came out recently it’s already skyrocketed to the single most watched video of the year. It offers a sneak peek into How Not to Diet. If you want to watch the one I did on my last book check out How Not to Die.


Obesity webinar

In 2019 I did a series of webinars on fasting, which you can find here. They were so popular I decided to do a whole series of webinars on a variety of topics in 2020 (in between my 200-city speaking tour!). The first one explores the origin of the obesity epidemic. Obesity exploded throughout the industrialized world in the late 1970s. What happened? Any potential driver would have had to be global in nature and coincide with the upswing of the epidemic. So how do the various explanations stack up?

I hope you’ll join me as I sift through all competing theories and answer your questions in this 2-hour live webinar. Check out the full list of topics here.

  1. Diet videos win again. Not at all surprised by 1 and 2.

    I am also not surprised about the oatmeal video being up there. It bested diabetes and cancer surprises me a little bit.

    I am surprised that time-restricted eating was 10th. So many people asked for it that I thought it would be higher.

    Bottled water is always a topic of interest to a lot of people.

    Eggs and butter are ones people who like them keep hoping for the science to keep turning back their direction, so those don’t surprise me either.

    How to cook greens is the only one that surprises me.

    I am surprised that the Keto diet versus Diabetes and the Keto diet versus Cancer aren’t up there.

    Are they in the Top 15?

  2. I went to Dr. and scanned through the year in the digital downloads and Apricot seeds didn’t make it.

    The brain ones like the Lutein didn’t make it.

    There were blueberries and ginger versus diseases, but oatmeal is still a favorite.

  3. Dr Greger says that multiple keto series videos made it to the top 10 category but he selected only one and supplied a link to the rest there.

    The list does not surprise me really . The one video that ‘shook my world’ was the greens video lol. I love spinach, and as for kale etc., not so much. Greens are expensive here anyway, and collards are not available. (never tried them).

    Oatmeal is interesting. I was reading the older videos on oatmeal over the weekend and came across some studies posted by ‘Darryl’. Oatmeal is protective of the stomach barrier apparently, and healing of leaky gut. As a former sufferer of acid reflux, I guess I owe part of my recovery at least to the daily bowl of oats!

  4. Silvertize is the brand of silver-infused cloth that actually does inhibit bacteria.

    I am wondering about safety.

    It is the one that really did pass Dr. Annie’s Experiments tests over and over again and Norwex failed. E-cloth didn’t do poorly.

    I am wondering environmentally if it is a pass or fail.

    Silvertize costs $50 for 5 cloths.

    E-Cloth costs $50 for 12 cloths.

    There are brands with silver-infused, like Udderly that sells a 25-pack for the same $50, but she didn’t test those.

    I am so tempted to give them to my poor friends and the homeless and to get those instead of the E-cloths, because of how many things it is tested to kill. Things like MRSA, which my cousin has.

    My grandmother had it and the concept of being able to clean with something proven to kill it would have been so much easier than the cleaning method I did.

    Once a patient has it, every nurses aide has to wear masks and gloves and aprons and it really ruins the peaceful atmosphere. They all got the flu anyway and we didn’t, but the MRSA was confusing for me. I think the Silvertize cloths are very tempting and they passed the test.

    Do they hurt the waterways? Do they hurt our health or our microbiome?

    It might take a while for the studies to come, but I would like to switch to water-only cleaning.

  5. I think I am going to buy some Silvertize and some E-cloths.

    People use Silvertize instead of hand sanitizer and they say that you genuinely don’t need to wash them unless you stain them.

    Not washing them and being able to use them dry seems like they would be less damaging to the waterways than other silver-infused things.

    It really is impossible to do the logic of things because products lie like crazy and there are so many variables.

    MRSA-exposure versus messing up my gut microbiome.

    Washing machine with a lot of water or using hot water and a sanitizing function versus a fabric uv light vacuum versus moving someplace with a lot of sunlight versus never having clean underwear.

    1. When I did the SpeedQueen washer logic, my brain was so bad and it was so hard to figure out.

      I think the logic I came up with was that SpeedQueen gave me a calculator of how many years the machine would last per load and I knew it actually killed germs and cleaned clothes and was made with steel parts, but it was small.

      I think I told people, if you have thin enough or small enough comforters to wash it in the SpeedQueen, which I do have, SpeedQueen is good, except for drought zones, but if you are going to have to spend a fortune at the laundry mat, you need a brand with a sanitizer that is big enough for your comforter.

      But, honestly, I broke down mentally just trying to figure out how to buy a washing machine and every, every, every topic is that complicated. Every single topic.

  6. I just realized that the silver one can be used with gloves and never needs to be washed.

    They can use it when they don’t have money for dish soap or cleaning supplies.

    I would like longer safety studies, but I am probably gonna clean with it.

      1. Washing machines don’t kill bacteria very well at all and they tell you not to dry the microfiber ones.

        The one that kills germs on its own wins.

        1. Realizing that they tell people they can use them on raw chicken but more and more people have washers that don’t clean and they tell them to not use dryers.

          People will get so sick eventually.

            1. I think I have to do it so that the YouTube videos get taken down.

              There are so many people selling them because of the raw chicken test.

              I can’t just let them kill people.

                1. But I did find some EPA registered cloths and those were $20 for 10 cloths.

                  Microfiber Pros 16” Cleaning Cloths with EPA Registered DG-300 Silverclear

                  1. Well, the cloths only last for a year or two or three, so it does end up in a landfill with the waterways being an issue.

                    Nope, I am not smart enough to figure out how many fewer plastic bottles and cleansers versus silver in landfills and the concept that you won’t know when they suddenly stopped working.

                    Too hard.
