Which means that the average person hearing the statement will draw
all sorts fo incorrect conclusions, of the same sort generally advocated
by folks who declare that "a calorie is a calorie".
For example, they will probably get out a chart of BMR, a calorie
counter, and a treadmill, and assume that the statement means that
exercise calories plus BMR should equal dietary calories.
Or they may (and the vast majority do) assume that since a calorie is
a calorie, a diet of 800 calories of sugar and 100 calories of butter
will promote weight loss exactly as well as any 1000 calorie diet. This
is exactly the claim of Moosh, for example.

Here "refuse" apparently refers to calories that pass through
undigested, but not to waste products that result from
metabolism. Waste products from metabolism are NOT insignificant:
glycolysis is about 4% efficient, for example.

That's an incomplete statement. If you awake alive tomorrow, and have
succesfully hoisted your body into bed last night, then apparently
your body met its energy needs SOMEHOW. This balance you speak of
exists, but only within certain limits.

For many, that's probably true. But not necessarily. I have lost

This is non-trivial, although several proposed methods exist. Increase
LBM is one. The "afterburn" from exercise is another. "Thermogenic" foods
are another. Some suggest that ketosis may be another.

Never hurts a bit.

You said "three" parts.

That doesn't appear to be what she means. The water weight loss ends
after the first few weeks. She appeared to be referring more to the
time one approaches one's goal weight.

I think that happens no matter what you tell people. How many people
actually know their daily burn rate anyway?

Yes, or metabolic intermediates that aren't fully metabolized, like
urinary ketones. Basically, any useful calories that the body
eliminates unused.

True, but consider that your body has lots of ways of reducing the
amount of calories it needs. It may decide to cut down on antibody
production, for example.

It does assume you're eating too much to begin with, which is the more
common case for the general public. My point was that eating too much
can make pretty much anyone stop losing weight.

Yes, this is the tricky part. Lyle's UD2 seems to focus on this
aspect more than others.

Unless you cause too much deficit, then you end up making #2 worse.

I lied ;-)

Well, I can't help with that then.
