The human physiological requirement (RDA if you like) for carbohydrate is…ZERO.
In the absence of dietary carbohydrate, de novo synthesis of glucose requires amino acids derived from the hydrolysis of endogenous or dietary protein or glycerol derived from fat. This is evolutionarily conserved.
I eat nuts daily as well in support my ketogenic diet, but never such massive quantity in one shot!
Although one might argue they are almost (maybe they are as a food group?) a perfect food…plant fat/protein/carb/minerals. I see the nutty attraction.
Yes BMI would be a confounder, but the SAD (Standard American Diet), rich in refined carbs and devoid of nuts, has been shown to lower lifespan (studies comparing various diets, including carbohydrate quality and plant based proteins/fats).
Its a misconception that fats like from nuts are somehow a lot better than carbs because most people in keto-mindset compare high GI carbs with fats. If you consider more primitive times where carbs from roots or plants were bound with resistant starches and fiber, its a different story. All macronutrients increase aging to some degree,
So if you eat much more calories in healthy fats it will increase aging more than less calories of healthy carbs. BUT if its toxic carbs like refined sugary products itll produce more damage in proportion to its calories.
Still, I ate 1500 calories of almonds yesterday several days after eating 4800 calories mixed nuts. I’m back at 100 lbs [103 after water). I gained like, 0 weight from these nut binges (but my binges were way worse late December, where they increased my BP for a while)
