A good post Tex. Thank you for posting it. It’s useful for all readers.
A couple comments; carbs (not simply glucose / “simple carbs”) come in many forms — some natural and others anything but natural. ALL carbs (dextrose, sucrose, fructose, etc….) go through various conversion processes eventually making glucose. The various substrates have differing actions though.
Far more in-depth than “simple carbs” and “complex carbs.” And far more in-depth than simply low and high glycemic.
The amount and rate at which insulin rises and falls varies RADICALLY!
And in the state of health (lack of health) that most Americans are in; insulin resistant / pre-diabetic and diabetic, along with the common frequency of consumption from morning into evening — insulin levels seldom drop into a normal range for the avg American.
Also, ancestrally, carbs aren’t much of a species appropriate macro. They aren’t common in nature (basically they weren’t globally available, and they were seasonal). What is common are fats (most abundantly saturated) and protein.
Being that carbs are technically a non-essential macro nutrient —non essential because we don’t have to exogenously ingest them to produce our body’s minimum need (because of processes like gluconeogenesis),an animal based diet (example: beef, fish, organs) is the most natural / species appropriate way of nourishment.
Excessive carb consumption came about only in fairly recent history. To the extent (and types) consumed, it’s highly unnatural.
So far as Fung as an “expert,” in a certain respect he is. He’s a nephrologist (as you’re aware) treating metabolic conditions daily in his practice, primarily via nutrition. Has written books on diet and nutrition and fasting, and a diligent researcher of nutrition and metabolic studies, etc. He qualifies as an “expert” of sorts.
Carbs can be / are a tool for various specific uses, but their consumption isn’t optimal for overall health. Sports supplements are another example of the same principle; effective as tools for various goals / uses, but not a true natural contributor to overall health.
Sorry for misspellings / grammar mistakes. Typing thoughts quickly on my phone between sets at gym!
Many of our ancestors lived in environments where fruit and starchy sources were plentiful and year round. Not all of us are descendants of the Inuit. Hunter gatherer tribes seem pretty fit to me. Pretty active peoples.
I agree that your DNA does affect how well you tolerate certain foods.
While we're on the topic, have you seen the Inuits? Kind of chubby little fellows for eating very few, if any, carbohydrates. Would their diet be considered carnivore? Lots of caribou if I recall.
