Interesting math:
*********
The IOM has determined healthy ranges of nutritional intake for adults to be:

45 percent to 65 percent of all calories from carbohydrates 20 percent to 35 percent of all
calories from fat 10 percent to 35 percent of all calories from protein

and.....

Children and adults need 130 grams of carbohydrates each day in order to maintain maximum brain
function.

i.e. that's the *minimum* level of carbohydrates that need to be consumed, not a typical level or a
maximum level.

*************

130 grams X 4 kcals = 520 kcals

i.f. the minimum number of calories that ought to come from carbs.

Quoted message said:

If carbs ought to be 45 to 65% of total calories:

45% carbs = 1156 total kcalories per day 65% carbs = 800 total kcalories per day

So if one eats the necessary amount of carbs per day to maintain maximum brain function and one
tries to keep the carbs, fats and proteins in the recommended ratios, adults will never eat the
recommended amounts of calories per day, which are in the 1700 to 3300 kcal per day range. In
fact, a 98 to 132 lb female adult will only get about two thirds of the needed calories (1156 vs
1700 at 45% carbs). Larger people even less.

Only if they decide to eat only the physiological minimum quantity of carbs.

If a large 6'1" - 139 to 188 pounds active male eats 65% carbs and tries to reach 3000 calories,
he would have to eat 1950 calories of carbs which is around 488 grams of carbs. That is 3.75 times
the amount needed to maintain maximum brain function. Ridiculous.

These number do not make sense in the real world. The entire calorie concept need to be chucked
out the window.

Those numbers do make sense in the real world. You could easily apply the same "logic" to other
macronutrients. Try applying it to the minimum fat intake required for absorption of fat-soluble
vitamins and steroid hormone synthesis (set rather conservatively at 10g/day), or the minimum
protein intake required to prevent muscle wasting (assume 1g/Kg/day). You'll find, even if you apply
the Zone ratios, that someone who consumes only the minimum amount of each macronutrient necessary
to prevent pathologies associated with deficiencies of that particular macronutrient won't be
consuming enough calories to meet his overall energy needs. Your hypothetical 165-pound man would
get only 910 calories from the physiological minimum levels.

You the epitome of the couch potato commenting on exercise and calories? That's like Bush talking
about balancing the budget. I laughed so hard at your moronic claptrap I almost [censored] my pants.
Please tell us you're trolling. To think you are serious is damn frightening.

So do the same on the protein in your diet. The stuff you
eat in gross excess, and which is so insulin-stimulating.
Ridiculous 🙂

Just because you don't understand? Sorry.
