Great and entertaining video. (Crap, I am lucky to be alive!)
It is truly frightening to consider that many diet gurus died at a relatively young age, despite their focus on a “healthy diet.” And I am also sure many of them took a lot of supplements like Durk Pearson did.
My feeling is that genes are king. Other factors, such as exercise and diet, either contribute to or detract from healthspan. Yes, calorie restriction, which is unpleasant for most humans, appears to extend lifespan.
So, I would attribute my lifespan, so far, and the lifespans of the health gurus in the video to “lucky or unlucky” genes.
I have been on various diets throughout my life. In my younger years, my diet consisted of whatever I was being served, whether at home or in the military. My diet could have been described as omnivorous.
My first exploration into diets occurred when I was trying to find foods that my daughter could eat because she was allergic to a great many foods.
Adele Davis was a popular health and diet guru at the time, so I was brewing up many concoctions from her cookbook, which leaned heavily toward fruits and vegetables.
During most of my life, I have been physically active, playing sports and going to the gym.
But my work locations made it hard or impossible to go to the gym or play sports. So, yes, there were times when I gained too much weight due to inactivity. This caused me to try such diets as the Atkins diet and, in later years, a ketogenic diet and time-restricted eating to lose weight.
At my current age, 84+, I am on time-restricted feeding, 18-7, because this is what feels natural to me at this time. My diet is again omnivorous because this is what I like to eat. I would lose way too much weight on a vegetable-based diet, because I don’t enjoy eating vegetables.
Bottom line: It is much easier to shorten your genetically given lifespan than to lengthen it.
I am thinking I am one generation too late to achieve any significant extension of lifespan through gene editing, medicines, supplements, etc.
