Bonafides: Former NASA Scientist, Co-founder of Zero Gravity, popularized using mild cold-stress for weight loss (as covered in The 4 Hour Body, by Tim Ferriss) and about to complete a 23-day (medically supervised) water fast
Btw, you bowel movements just stop after a while
Long fasts are socially draconian, but not physically draconian
I don’t have headache, hunger pangs, etc.
Fasting is helping people with diabetes, lowering blood pressure and even Ezcema
The idea that the body gets into a repair mode when in a dietary restrictive environment is not that far fetched, but how to you sell sitting around and drinking water?
Once we have dietary restriction we’ll need to supplement to make sure we’re not malnourished
Over past 23-days Ray’s blood levels were all at healthy levels
Myth: You don’t need comprehensive nutrition every single day, maybe over any given week or month, but we don’t need everything every day
Which makes sense if we evolved often not having food available every day as hunter-gatherers
AND you can be clear headed and effective when fasting, as we needed to be able to hunt without eating and do it successfully
What is an adequate level for vitamins/minerals?
The RDAs (recommended daily allowances) were set based off animal studies about what levels caused death
But what about the stuff that are not essential for short term survival, but essential for long term survival and damage repair (Triage Theory, Dr. Bruce Ames)?
But we also don’t know the consequences of over-nutrition?
Start thinking about diet about a lifetime thing, not a daily thing
g. At a certain age you are trying to have children, so you want more amino acids to help with fecundity
At older ages, you want to aim for longevity and have fewer amino acids
How do we look at HealthSpan: Live long and be functional when old, not just technically alive
Myth: Going without a meal will crash your metabolism or by not including a food group in every meal
Also, none of us are going to be deficient in protein, not happening in the West
Original rules were written when we didn’t have enough food and it was about making sure we had enough, now this is not the case
Now, what more can we get at a micro-nutrient level to optimize our health
Over-nutrition is rare in nature, not a big thing
But now we are over-nourished by a calorie density perspective
Strictly a disease of affluence that the US exports to other nations
Ironically, we are undernourished in key micro-nutrients, even though getting lots of macronutrients
Dietary restriction is not Caloric Nutrition and can be done without being malnourished
Micronutrients come mostly from plants, even though they don’t have a lot of calories
