*Many people are interested in loosing weight and keeping it off. Popular
Diets often boast these claims but in fact do the opposite. The information
below is from Dr James Kenney, PhD, RD, FACN, Nutrition Research Specialist
who is board certified in Human Nutrition.
Just as your car runs best on a certain type of fuel, so does the human
body. Unfortunately the latest low-carbohydrate (CHO) fad diets are not the
fuel mix the human body was designed to run on. Here are 10 main health
risks associated with consuming a high-protein, low-CHO diet over the long
run.
1. Poor Long Term Weight Control
There is no metabolic magic in low-CHO diets. Those who continue to lose
weight after the first week do so because they decrease calorie intake. This
can occur because of decreased dietary variety. Greatly limiting the number
of foods that people are allowed to eat, reduces their food and calorie
intake. But a reduction in variety most often leads to boredom and cravings
over the long run. One recent study showed that a high protein meal leads to
a greater tendency towards binging of foods, high in sugar and fat, later in
the day.
2. Fainting
Orthostatic hypotension, or a rapid drop in blood pressure when you go from
lying down to standing, is caused by a loss of fluid and electrolytes and
reduced sympathetic nervous system activity. Both of these occur when your
body is deprived of CHO. This may result in dizziness or even fainting when
you stand up quickly.
*If you are really interested in loosing weight and keeping it off, you want
to know the pros and cons of a Diet before you start it. The claims made by
diet programs are not always true.
3. Reduced Athletic Performance Don't let the wrong fuel mix run you down!
Athletic performance is reduced on a low-CHO diet. Since the 1930's it has
been known that a high-CHO diet can enhance endurance during strenuous
athletic events. Mountain climbers and skiers should be warned that a
ketogenic diet greatly increases the risk of mountain sickness.
4. Keto breath
Keto-breath can be described as a cross between nail polish and over-ripe
pineapple. This is common for dieters who consume so few CHO that they put
their bodies in ketosis. Your best bet for permanent weight loss and
control, as well as good health, is twofold:
1) increase the amount of fruits, vegetables, nonfat dairy products, whole
grains and beans that you eat.
2) eliminate calorie-dense foods such as cookies, sugary desserts, bagels,
crackers, chips, fries, pizza, candies, etc. Research on people who have
successfully lost a lot of weight and kept it off long term, shows that the
vast majority succeeded by consuming a low-fat diet high in fiber coupled
with regular exercise.
*If weight loss and lowering your cholesterol is on your mind, then you want
an effective diet to do both. A balanced diet and exercise is the best way
to accomplish this. This diet should limit fats and concentrated sweets
while increasing your daily activity. Popular Diets Do Not Always follow
these guidelines. The information is about The Atkins Diet and other
Low-Carbohydrate Diets which are unhealthy.
5. Heart Disease Risk Increases
Risk of heart disease is increased greatly on a low-CHO, low-fiber diet that
is high in animal protein, cholesterol and saturated fat. All three raise
serum cholesterol, particularly LDL or "bad" cholesterol. Elimination of
high-CHO, high-fiber plant foods, that help lower cholesterol, compounds
this problem. A high meat intake may excessively increase homocysteine
levels and iron stores in the body. There is growing evidence that high
levels of both may increase the risk of heart disease.
6. Gout
An excess of uric acid in the body causes gout. This excess can be caused by
an increased intake of foods high in purines, which are broken down into
uric acid in the body. Meat, poultry, nuts, seeds, eggs and seafood are all
fairly high in purines. Elevated levels of uric acid in the blood may lead
to needle-like uric acid crystals in joints.
*Instead of following a Low-Carb or Atkins Diet, try a balanced diet. The
DASH diet is balanced, includes the characteristics you want and increases
your intake of vegetables. The DASH diet research has proven it controls
hypertension, and helps to lower cholesterol. It can also be designed for
healthy weight loss.
Fruits and vegetables are not included in sufficient quantities in the
Low-Carb diet. This is a very serious omission. There are many
phytochemicals found in a healthy diet which includes a wide variety of
fruits and vegetables. The phytochemicals play an important role in cancer
prevention.
7. Cancer Risk Increases
Risk of many cancers is likely to increase when most fruits, vegetables,
whole grains and beans are eliminated from the diet. The National Cancer
Institute currently recommends, based on the bulk of scientific research,
that you eat a plant-based diet that is high-fiber and low-fat.
8. Osteoporosis
Over time, excess protein intake, especially from animal sources, increases
the loss of calcium in the urine which may contribute to osteoporosis.
The DASH diet [Dietary Approaches to Stop Hypertension], has been shown to
be of great effectiveness in combating this significant health risk. Fruits
and Vegetable are a major ingredient in the dietary approach to fight the
dangers of high blood pressure. They also help with weight control by taking
the place of high fat - high sugar snack choices.
9. Rising Blood Pressure with Age
Blood pressure will likely increase with age on a typical low-CHO diet. In
part, this is because a high-CHO, high-fiber diet includes more fruits,
vegetables, whole grains and nonfat dairy products. This diet was shown to
lower blood pressure most likely due to its higher content of key minerals
such as potassium, calcium and magnesium. Also low-CHO diets do not restrict
salt intake, the main reason blood pressure rises with age.
10. Kidney Stones
Both uric acid and calcium oxalate stones are more likely to form on a high
protein, ketogenic diet than on a higher carbohydrate diet with more fruits
and vegetables.

Low Carbohydrate Weight Loss
Ketogenic Diets - The Evidence
By James Collier BSc (Hons) - Consultant in Nutrition and Moderator of
Dietetics.co.uk
Email: 
ja...@dietetics.co.uk
People are always looking for a quick fix to lose weight and, as health
professionals, we are frequently questioned about new weight loss diets on
the scene. Low carbohydrate, high protein or ketogenic diets are one of
these 'faddy' diets. They are not a new concept, but, with huge media
coverage from the 'success' of stars like Geri Halliwell and Jennifer
Aniston, many more people are following these regimens.
Low carbohydrate, high protein or ketogenic diets seem to be all around us!
They have been 'fashionable' on and off for years. Many of your patients,
colleagues or even you may have tried such programmes, so it is important
that you, as a health professional, are aware of the evidence. Do they
'work'? Are they healthy? Are there more efficient ways of controlling your
weight?
Collectively, these regimens are known as 'low carb' or 'ketogenic' diets
and have many variants. One of the better known is the Atkins diet, around
since the 1970s. Others include Radiant Health (Professor Brian Peskin), the
Carbohydrate Addicts Diet (Dr Richard Heller and Dr Rachel Heller), the Diet
Cure (Julia Ross), Protein Power (Dr Michael Eades and Dr Mar Eades), Eat
Fat, Get Thin (Barry Groves), and many more.
The Claims
These diets claim to alter the way we metabolise food, and their advocates
argue that obesity is a consequence of dietary carbohydrate rather than
dietary fat or total calories. It is claimed that excess dietary
carbohydrate raises insulin levels which, in turn, causes more body fat
deposition. The theory is that a higher protein in relation to carbohydrate
intake lowers insulin levels and causes weight loss. These diets are also
said to help food cravings and help fill you up as protein foods promote
satiety. Other health claims are that they improve lipid profiles and
benefit hypertension.
The Scientific Evidence
There is absolutely no evidence, though, that weight loss can be achieved in
any way, other than by creating a negative energy balance, i.e. weight is
lost when we burn up more than we eat. There is also considerable evidence
that hyperinsulinaemia, hyperglycaemia, hyperlipidaemia and hypertension are
closely linked to obesity, and that weight loss by any means improves these
health parameters (1).
There is evidence that calorie deficient low carbohydrate, high protein
diets do produce a more rapid and greater initial weight loss compared to
isoenergetic more moderate carbohydrate diets, with the associated risk
factor benefits (2,3). Unfortunately, the initial high rate of weight loss
is not only due to reduction in energy stores, but primarily due to changes
in fluid balance. The reduction in muscle glycogen (the storage form of
carbohydrate) stores is accompanied by a reduction in water; for every 1g
glycogen metabolised, 3g of water is lost.
Also, on extremely low levels of dietary carbohydrate (i.e. less than
50-100g per day; 10-20% total energy intake) high levels of ketones are
produced. Ketones are used as a fuel by the brain and heart muscle during
times of low food intake and help keep us alive. The presence of ketones
means increased sodium and potassium and associated water loss (more weight
loss), bad breath, taste changes and nausea, which obviously may lead to
reduced food intake.
Ketogenic diets are very limited in variety, and variety in the diet is one
of the fundamental healthy eating guidelines in order to achieve a balanced
diet and optimal nutrition. They fill you up more than on diets of
comparable energy intakes with a higher carbohydrate : protein ratio.
Protein rich diets also increase thermogenesis, and therefore 24-hour energy
expenditure more than with similar energy higher carbohydrate intakes (4).
Whether this persists longer term remains untested.
As a consequence of all the above in ketogenic diets, there is greater
potential for a negative energy balance, hence consequential weight loss.
Weight loss is therefore not due to raised serum insulin levels promoting
body fat deposition. There may also be a consequential reduction in lean
body mass.
Potential Problems
Low carbohydrate diets are, by definition, high in protein and fat. As less
fibrous starches are consumed, there is a reduction in dietary fibre intake
too, as well as antioxidant vitamins and minerals. These factors signify
increased risk of cardiovascular diseases, cancers, renal disease and bowel
disorders. Other problems are the negative consequences of the ketotic state
discussed above.
Nutritional intakes of people on low carbohydrate, high protein diets have
been shown to be low in calcium content, as are the intakes of people
following more orthodox weight reducing regimens. This is a result of
general low food intake. However, low carbohydrate, high protein diets may
also lead to increased calcium excretion and reduced bone mineral content
(5). There is insufficient evidence of the direct effect of the low calcium
content of low carbohydrate, high protein diets increasing risk of
osteoporosis later in life, but it is very likely. The group most likely to
follow ketogenic diets are women 15-30years old, the main bone building
years where a good calcium intake is crucial.
In Summary
Low carbohydrate, high protein diets are no 'magic' answer for weight loss,
and certainly do not follow the well-evidenced healthy-eating guidelines.
They also have the potential to cause nutrition related problems to health.
However, there are no studies comparing the short-term use of such diets in
relation to health problems, so there may well be benefits of short-term use
outweighing any potential risk for certain obese people who really struggle
to lose weight by more traditional means (6). There is no evidence
describing what 'short term' actually means. Further research is therefore
required. Also the extent of physiological adaptation to these regimens is
unclear.
There is very good evidence though, that manipulation of low fat, moderate
protein and moderate carbohydrate is more promising in respect of efficient
and consistent weight reduction (6). This, of course, is improved further
with the inclusion of an associated increase in physical activity.
Whilst many people do claim some good initial weight loss with low
carbohydrate, high protein diets, this rate of loss slows down after a few
weeks. Most people also claim to put most, if not all, the weight back on
(and sometimes more) when they cease the 'diet'. Therefore defeating the
object of following such a stringent plan. Many may follow such regimens for
a special occasion or seasonal preference, which could lead to significant
weight cycling, identified in its own right as a risk factor for
cardiovascular disease.
Low carbohydrate, high protein diets do not fit in with healthy eating
guidelines, they are unbalanced and difficult to fit in with lifestyles and
family meals. They also take no account of the psychological influences of
why people over eat, crucial in any weight reduction programme.
Ketogenic diets are not recommended for pregnant or lactating women,
children and adolescents, for kidney or bowel disease patients or, indeed,
for general use. However, with more research, there is the potential for
short-term weight reduction in high-risk obese patients.
Key Points
Some evidence for greater initial weight loss compared to equivalent
hypocaloric, higher carbohydrate diets
Main difference in weight loss is from fluid from reduced glycogen stores
and the ketotic state
Improvements in health parameters is associated with the weight loss and not
directly from the diet itself
Potential for increased risk of a number of nutrition related diseases
Insufficient research exists and further randomised, controlled cohort
studies are required in order for specific recommendations to be made

Low carb diet increases kidney stone risk
[ Questions & Answers >  LOW CARB DIET INCREASES KIDNEY STONE RISK ]
 Low carb diet increases kidney stone risk
Reported by Susan Aldridge, PhD, medical journalist
The popular low carbohydrate high protein diet may not be very good for your
long-term health.
Researchers at the University of Texas tested the effect of a diet which was
low in carbohydrate on ten healthy subjects. For two weeks they ate a normal
diet, and then switched to one which had some vegetables, no fruits, and
less than 20 grams of carbohydrate a day for two weeks. This low carb diet
had a drastic effect on body chemistry, the researchers say.
Levels of citrate in the urine fell. Citrate is needed to protect against
the formation of kidney stones. So the diet might increase the risk of
kidney stones. Then acid excretion went up - which suggests that the acid
load in the blood had increased, probably because of the acidic content of
meat, which is a big component of this diet. This is likely to result in
bone loss - so the diet could increase your risk of osteoporosis.
There's no doubt that any restricted diet can lead to short-term weight
loss. But complex carbohydrates and fruits are essential for maintaining
health - cutting them out long-term can only upset the body's balance. This
in turn could lead to problems, like osteoporosis and kidney stones, as this
study shows.

 and vegetables.
E cinque. Fiber and vegetables. Che palle!
Nessuno impedisce di mangiare adeguate proteine e contemporaneamente
tutta la verdura e la frutta che si vuole. Giudicare una dannosa una
dieta ricca di proteine solo perché la si presume (in base a che?)
povera di frutta e verdura č un clamoroso falso ideologico, nonché
l'ennesima dimostrazione della cattiva fede di chi scrive certi
articoli.
Di nuovo, le ritenzioni di sali che portano ai calcoli dipendono
da squilibri ormonali prima che dalla dieta.
La sequenza logica č:
dieta --> sistema ormonale --> ritenzione --> calcoli.
Ho scritto sistema ormonale per non scrivere ancora "in...".
Vabbč, era chiaro.

 fisiologiche?
 
Ne sono convintissimo. Il corpo non produce ottusamente "case" solo
perché ha "mattoni" disponibili. Il corpo ha dei meccanismi di
regolazione estremamente sofisticati. L'insulina è un ormone
peptidico, ossia composto di aminoacidi. Ma nessuno pensa che la
produzione di insulina sia direttamente proporzionale alle proteine
ingerite.
Se bastasse mangiare più colesterolo per produrre più testosterone
nessuno avrebbe bisogno di andare in palestra. Quello che è certo
è che bisogna fare in modo che il corpo abbia a disposizione la
materia prima per produrre quello che serve in caso di bisogno.
Ecco perché secondo me un bodybuilder, a maggior ragione un
bodybuilder "natural", una volta coperto il fabbisogno di glucosio
determinato dalle necessità per l'allenamento, farebbe meglio
a sostituire il resto dei carboidrati con i grassi.


 indurre questo tipo di problemi.
Non direi, a giudicare da quello che risulta da questo studio (9), o in
questo (10). E comunque basta esagerare nel consumo di frutta, specie di
quella più zuccherina.
E questo è il motivo per cui nellaltro post ho scritto (lo ripeto per
intero):
Anche la frutta è importante, ed io ho scritto anche questo, ma la capacità
limitata dell'organismo umano di metabolizzare il fruttosio la dice lunga
sulle quantità di
carboidrati che dovevano assumere normalmente i nostri antenati!
In pratica: Se i nostri antenati non mangiavano cereali ma frutta, bacche,
radici, ci sono buoni motivi per credere che il loro consumo giornaliero di
carboidrati non fosse (teniamoci pure MOLTO larghi) superiore ad 80-100 gr.
Considerando il fatto che erano individui non certo sedentari, direi che le
attuali stime che ci vorrebbero uniformare ad unassunzione di zuccheri
decisamente più elevata, anche in mancanza di unadeguata attività fisica
eseguita su base
regolare, lo facciano solo ed unicamente perché è stato ritenuto
universalmente valido un modello alimentare empirico (la famigerata
Piramide), che però non tiene conto in alcun modo della biochimica umana.

 I primi piatti.
 
Ah, ah, ah Lorenzo....
...tu sei un ortodosso, quindi devi accettare il fatto che i primi
piatti a base di pasta sono scomparsi anche per la scienza ufficiale.
Ormai la cito ogni volta:
la piramide alimentare proposta da HARVARD, ti dice niente il nome?

Anche voi ortodossi e mediterranei dovete smettere di propagandare

 a sostituire il resto dei carboidrati con i grassi.
I controlli a feed back della sintesi ormonale si regolano proprio sui
substrati circolanti.
Ma mi avevi chiesto cos'altro oltre l'insulina la leptina e le proteine
disaccopianti...
Gli ormoni glicocorticoidi ma anche sopratutto il sistema nervoso autonomo,
quest'ultimo prima o poi prende la situazione in mano sbattendosene
dell'insulina o dei substrati e ti fa tornare al tuo peso genetico standard.
L'amico SNA è quello che decide sopra di te che fare nelle regolazione delle
tue funzioni vitali, decide a che ritmo far andare il cuore ed il respiro,
controlla il peso e decide di spostarlo gestendo la fame.
Pensa a causa sua si muore annegati...
Quando anneghi è lui che decide di prendere una boccata d'acqua nei polmoni,
nessuno volontariamente lo farebbe, così si muore per annegamento con acqua
nei polmoni, se muori prima nei polmoni non trovi acqua.
I controlli sul peso sono tanti e quasi tutti a feed back, se non c'è
glucosio si ottiene comunque attraverso la gluconeogenesi durante l'azione
del glucagone, le proteine producono scorie da eliminare ed aumentano "la
fatica" renale.
Si non è dimostrato che tante proteine = danni.
Ma cos'è che preso ad elevato dosaggio non fa male? Anche con tanta acqua
muori.
Per quanto mi riguarda demonizzare i carb è sbagliato, almeno non tutti.

Ortodosso si ma anche critico...
perché, oltre un miliardo di persone mangia riso bianco tutti i giorni,
senza risultare travolto dalle obesità o patologie degenerative.
Poi gli statunitensi sono una popolazione grassa perchè mangiano troppo.
Ogni giorno gli Stati Uniti fabbricano 3800 calorie per ogni cittadini,
quando il fabbisogno medico - tra donne e uomini - varie dalle 1600 alle
2200 calorie.
In più quello che viene definito "precessed-food", il cibo standardizzato e
impacchettato, costa pochissimo all'origine e relativamente poco anche al
pubblico: se posso comprare due hamburger al prezzo di uno (o quasi),tanto
vale approfittarne.
L'ultimo investimento pubblicitario McDonald's è stato pari a un miliardo di
dollari, contro il milione di dollari speso dal governo per incentivare il
consumo di frutta e verdura.
Poi la pericolosa patata, cucinata al forno e mangiata con la buccia apporta
appena 150 calorie, una dozzina tra minerali e vitamine ma anche tante fibre
quanto una tazza di cereali.
E poi tutti sono sulla pericolosità dei carboidrati raffinati, dalle
merendine in giù nella genesi di numerosi carcinomioncordi.
Gli statunitensi non hanno MAI seguito la piramide alimentare vecchia,
Ciao
Lorenzo

 Per quanto mi riguarda demonizzare i carb è sbagliato, almeno non tutti.
Demonizzare è sempre sbagliato. Ma i carbo hanno goduto
immeritatamente di ottima stampa per qualche decennio. Senza
demonizzare nessuno, è il caso di farli scendere giù dal piedistallo.


 Tutto vero, tutto bello. Ma che c'entra con la dieta?
Conoscere quei sistemi spiega come il controllo alla lungo termina sia fine
e slegato dal tipo di dieta.

Verranno ridimensionati, ma mai eliminati a livello low carb.
Vedremo... :-)
Ciao
Lorenzo

 Poi gli statunitensi sono una popolazione grassa perchè mangiano troppo.
Scusa, ma adesso che una "istituzione ufficiale" di altissimo livello,
fa marcia indietro sui carboidrati complessi e sui grassi
monoinsaturi, avendo avuto come base di partenza la vecchia piramide
alimentare, che ha potuto testare per 30 anni, e afferma che pasta,
riso e patate sono sulla stessa barca dello zucchero, tu la critichi
utilizzando delle tesi che partono da  considerazioni
"epidemiologiche"?
La vecchia piramide era un primo risultato basato alla fine su
considerazioni epidemiologiche di vasta scala e per di più utili ai
"fabbricanti" di cereali raffinati.
La nuova piramide è il risultato di un aggiustamento su basi ben più
scientifiche.
Dobbiamo tornare indietro di trent'anni??!!
Il fatto che milioni di persone mangino riso e non muoiano NON
SIGNIFICA che se ne mangiassero di meno non potrebbero stare meglio!!
Una istituzione di alto livello non corre il rischio di andare CONTRO
CORRENTE senza avere possenti prove del fatto di avere ragione.
Quindi per me la nuova piramide SEPPELLISCE quella vecchia e chi
continua a mangiare tutti i giorni anche 80 grammi di pasta SI FA DEL
MALE!

Nessuno parla di eliminarli. Mangiare frutta e verdura è sempre buona

Salvo dimenicarsi che pane e pasta SONO carbo raffinati. O no?

 Io sono dell'idea che il fruttosio della frutta basti ed avanzi.
Quindi l'accorgimento di sostituire il comune saccarosio con il fruttosio lo
sconsiglieresti?
Considerando anche che, essendo piu' dolce (del 50%

), se ne assumerebbe
meno?

p.s. non t'azzardare a rispondermi "Sarebbe meglio non usare nessuno dei 2"

 o qualcosa del genere!   ;-)))
mi viene da pensare al miele....che quando e' completamente naturale e' 
un dolcificante naturale.
Secondo me e' poco utilizzato ,perke' ha un retrogusto molto forte , che 
nel caffe , bevande ,dolci si avverte molto.

A freddo... altrimenti con il calore riduce il suo potere

Gli zuccheri semplici li puoi gestire come meglio credi, ma senza esagerare

Ciao
Lorenzo R.

 Questo è il corollario alla tua affermazione. O no?
Sei saltato alle conclusioni in un discorso più ampio.
Il senso che volevo dare io è che i fattori sono tanti molti dei quali
slegati da cosa si mangia.
Chetogenica o altro ci sono non pochi casi refrattari a qualunque proposta,
una fascia che passa il problema dieta e va avanti.
I drop out degli studi sono sempre tanti...
