For some people, if not all people, it MUST be true that:

Consuming 1,000 Kcal of Fructose is NOT metabolically equivalent to
consuming 1,000 Kcal of Bacon grease.

Why not???? I'll tell you why:

1. Not all foods have EXACTLY the same absorption in the gut. Most
of the
fructose calories will be used by the body, while a greater
percentage of
the bacon grease calories will end up in the toilet.

2. The energy USED by the body in metabolizing & processing is not
EXACTLY
the same for all foods. Again, my hypothesis is that sugary/starchy
foods
are much more easily processed by the body.

I doubt it is so high, myself, for 'average' folks, and I have heard
that sort of differential factoring is accounted for in the
calculations of caloric loads of different foods (for average folks).
Of course, for us overweight people, we have visual evidence that our
bodies react differently to food than 'average' folks.

It's all about the insulin ... carbs stimulate insulin, protein/fats don't,
or at least *very* little.

I'm no scientist so bear with me here, but the insulin spike you get with
the fructose (or any carbs, to a greater or lesser degree) means your body
is going to store any excess calories as fat. Too many such insulin spikes
can leave a person insulin resistant, which means the body is producing more
and more of the fat-storing insulin because it's not registering ... and if
it continues you end up with type 2 diabetes if you're not careful.

Hence the idiocy of the high-carb diet so commonly prescribed for diabetics.

I'm sure there are others here who can explain it all soooo much better than
I can! This is essentially what I can recall from reading DANDR.

When my GP told me I was insulin resistant, she said my body is extremely
efficient at gaining and retaining weight.

bloody brilliant ...
