to deal with about 80g of carbs a day
don't you mean 800g ? 80gm isn't even one slice of bread… if your figure was right we'd all be dead.
Slice of bread is about 10-15 grams of carb.
Here it says 12 grams of carbs in bread so your body deals with about 8 slices a day, that's quite a lot of bread really.
Also it has been proven by many people in many races that you can live without any carbs what so ever, so dying from lack of carbs is a bit of a myth.
12000 years ago we didn't eat many carbs at all, we didn't have agriculture so no bread or pasta and not many spuds. Now I'm no expert on evolution but 12000 years isn't long enough for a major rearrangement of our systems such that you could convince me that we have evolved to eat 800g of carbs a day.
Now I don't advocate atkins or no carbohydrates but a bit of thinking tells you that we probably too many carbs.
Anyway my Dr mate mentioned previously has been working with the British Diabetic society researching lower carb diets for diabetics and guess what, loads of them (only a certain type cant remember which one) have gone insulin free. They get all their energy from fats and protein.
It makes me laugh when people say that eating fat makes you fat.
How do you make a cow or chicken fat? You feed them grain.
