[It’s about] the superior nutrient density of animal products. Why don’t you do ahead and try your hand at comparing a kale and spinach meal with an equal calorie meal that includes meat.
And don’t forget, we [paleos] can eat kale and spinach too.
It’s not what you are eating because we can eat everything you do (in terms of fruits, veggies, tubers or even nuts). It’s what you can’t/don’t eat that is calorie for calorie, more nutrient dense.
For instance, take your kale and spinach meal, reduce whatever it is by 400 kcals and replace that with 400 kcals of some animal product: meat, fish, fowl, eggs or even dairy. You only improve the nutrient profile.
That’s the point.
And that’s my point, too.
I’ve got better things to do than eat 6 or more large meals a day. I can’t be carrying around all that food on my back, I’ve got shit to do. I’d rather have 2 or 3 small nutrient dense meals a day, not be hungry, and be able to have a kick-ass fasted lifting session at the end of it all.
