Quoted message said:Quoted message said:The Atkins is not a high protein dite, it's a high fat diet.
Most people assume that, but it's actually a low carb diet.
It is both. But specifically it is the opposite of a low-fat diet, ie
it's a high-fat diet. He (Atkins (!)) particularly states that you
should not consume too much protein because if you do then it will be
digested in the same was as carbs are digested (ie using insulin).
Quoted message said:It
prohibits sugary foods and high GI carbs like potates, bread and pasta.
It says you can eat as much protein and fat as you want, but in practice
you don't, since you don't have so much of an appetite.
This is true and for a specific reason : on the Atkins diet you are
primarily metabolising fat, not glucose. This means that you do not
have an insulin peak / blood sugar crash cycle as occurs with a high-
carb diet (and to a lesser extent with a high protein diet). The method
won't work on a high-protein diet because the insulin/sugar cycle will
still be there.
Quoted message said:Hence you don't
actually eat that much fat, otherwise people wouldn't lose weight on it.
This is not what Atkins says however, he specifically make an
injunction about over-consumption of protein and no such statement
regarding fats, and for the reason I gave.
Quoted message said:The mistaken assumption that Atkins made was that it was the fat
component that made the diet work, and that's what everyone makes the
fuss about, but it's now being proven that it's the protein component
which makes it work, the protein suppresses the appetite.
I don't know why you believe that has been proven ?
Atkins quotes many references to the academic literature that indicates
that it is the fat consumption that causes the weight loss. One that
particularly caught my eye was a reference to an experiment that showed
that the diet that caused the highest weight loss was 1000 cal/day of
pure fat. This aparently beat all other comers inclusing a starvation
diet. My understanding from the book is the original experiment has
been confirmed by other, later researchers.
I personally have no regard for the calibre of pundits who can be seen
on TV or read in the press. There are so many instances where they've
been proved wrong in the past, eg vegetable fats vs animal fats, that
their credibility seems to me to be very dubious. Of course one could
argue that Atkins has something of an axe to grind, but at least he
goes to the trouble of quoting the relevant literature in his book. I'm
interested to know what papers the high-protein diet afficionados are
relying on ?
Quoted message said:Thus a low fat version of the Atkins diet would work even better.
There is no reason to believe that ?
Quoted message said:So if
you feel hungry, eat a few low fat beefburgers, and don't pile on the
chips!
Agreed, but why low-fat beefburgers when high-fat ones are more effective ?
I know this is only a single data point, but I have done the Atkins
diet and have lost more than 3 stone on it, sustained for 2 years. I
have basicaly followed Atkins's strictures and have avoided overly high
protein consumption while consuming lots of fats and green veg. It is
of course true to say that Atkins' diet could work and still for his
reasoning to be invalid but this is vaccuously true : it can be said
about anything, and noone I have heard has given any *reason* for
believing it is true in this case.
The reaon for all the fud over a high-fat diet by Atkins knockers is
simple : they have spent all their lives earning a living by
promulgating second-hand derivatives of unread and misunderstood papers
in second-rate journals that suggest that a low fat, high carb diet is
healthy. Now faceing a diabetes and obesity explosion, caused by their
advicem they are trying to cover their tracks. Rather than admit they
are wrong about fats they are promulgating the line that high levels of
protein are the way to go.
I haven't tried a high-protein diet but from what I've read in the
body-building fora I believe you are more likely to put on weight rather
than lose it on such a diet. Of course that may be what you want,
especially if it is lean muscle weight, but if you are still subjecting
your body to the insulin / blood sugar peak cycle then it will have the
same risks as a high-carb diet.
