1) laws of Physics don' change for anybody. Whether one is stupid or not, whether one is self styled new age nutrition guru or not.
2) I called them stupid for a very specific reason mentioned in blue (and conveniently overlooked by you)
Everyone, who is past the age where his/her respective height has stopped increasing. That could happen at 15 for me, 25 for you. Growth state requires high calories, stagnant state doesn't.
With each passing year, you tend to lose your muscle mass - another reason to understand that your bodie's calorific requirement will go down as you age.
With each passing step closed to old age, you tend to do less of manual labor work - another reason to realize that you don't require as many calories as you once did.
Even the sportsman that does 400 m sprints - his training will decrease 25 years onwards due to injuries (that will happen more frequently and stay longer with age).
Anyway, you are simply trying to divert the discussion away from sugar by getting onto a tangent. We can debate back and forth on a separate thread if you want.
Save the thanks for the carnivore lobby funded to hilt by USDA

Selling grains/legumes is more profitable or selling meat & milk?
Oh and you conveniently ignored answering about Fats being better source of energy for the muscles involved in intense workouts.
