e oggi la detta anche Bigazzi alla 'Prova del cuoco'.
Buono quello. Un "talebano" dell'alimentazione, e, fondamentalmente, un
povero minchione. Così almeno giudico uno che si vanta di non avere TV,
lavatrice, e lavastoviglie.

Se è disinformazione pura il posto giusto per discuterne è proprio questo.
Io seguo le discussioni su Zona e Low-carb da troppo poco tempo, mi sarebbe
sufficente l'indicazione di uno studio scientifico, se esiste, che dimostra
che la Low-carb non faccia aumentare il rischio cardiaco, di ipertensione e
di altre malattie ischemiche.
Te ne posto una parte perchè li ho sotto mano. Erano quelli allegati al post
che avevo mandato su ISM e che mi hanno censurato. Li allego in fondo.

Mi resta un mistero anche come possono 150 grammi di grassi al giorno non
alzare il colesterolo e far venire un infarto.
Qualcosa di interessante, ed abbastanza esaustivo, lo puoi già trovare qua:
Poi ti consiglio di armati di Google e di cercare "low-carb", e affini, nei
vecchi messaggi del NG, ed anche su it.sport.palestra. Sono almeno tre anni
che si discute di questo argomento, si è portato di tutto, compreso decine
di studi a favore....ed un paio contro! [:-P]

Effect of a high saturated fat and no-starch diet on serum lipid
subfractions in patients with documented atherosclerotic cardiovascular

"CONCLUSION: An HSF-SA diet results in weight loss after 6 weeks without
adverse effects on serum lipid levels verified by nuclear magnetic
resonance, and further weight loss with a lipid-neutral effect may persist
for up to 52 weeks."

Effects of high fat versus high carbohydrate diets on plasma lipids and
lipoproteins in endurance athletes.
Brown RC, Cox CM.
Department of Human Nutrition, University of Otago, Dunedin, New Zealand.
"CONCLUSIONS: During periods of endurance training when energy requirements
are high, increasing the percentage of fat in the diet to approximately 50%
of total energy did not result in adverse changes to the plasma lipoprotein
profiles of this group of athletes."

Effect of a high-protein, high-monounsaturated fat weight loss diet on
glycemic control and lipid levels in type 2 diabetes.
Parker B, Noakes M, Luscombe N, Clifton P.
CSIRO Health Sciences and Nutrition, Adelaide, Australia.
CONCLUSIONS: Both dietary patterns resulted in improvements in the
cardiovascular disease (CVD) risk profile as a consequence of weight loss.
However, the greater reductions in total and abdominal fat mass in women and
greater LDL cholesterol reduction observed in both sexes on the HP diet
suggest that it is a valid diet choice for reducing CVD risk in type 2

Effect of a high-protein, energy-restricted diet on body composition,

CONCLUSION: Replacing carbohydrate with protein from meat, poultry, and
dairy foods has beneficial metabolic effects and no adverse effects on
markers of bone turnover or calcium excretion.

"In conclusion, an increase in dietary protein results in a number of
metabolic adaptations in addition to reducing the circulating glucose
concentration. Serum TSH, total T(3), free T(4), B(12), folate,
homocysteine, uric acid, and creatinine concentrations were unchanged."
A randomized trial of a low-carbohydrate diet for obesity.

"BACKGROUND: Despite the popularity of the low-carbohydrate, high-protein,
high-fat (Atkins) diet, no randomized, controlled trials have evaluated its
efficacy. METHODS: We conducted a one-year, multicenter, controlled trial
involving 63 obese men and women who were randomly assigned to either a
low-carbohydrate, high-protein, high-fat diet or a low-calorie,
high-carbohydrate, low-fat (conventional) diet."
"The increase in high-density lipoprotein cholesterol concentrations and the
decrease in triglyceride concentrations were greater among subjects on the
low-carbohydrate diet than among those on the conventional diet throughout
most of the study. Both diets significantly decreased diastolic blood
pressure and the insulin response to an oral glucose load."
"CONCLUSIONS: The low-carbohydrate diet produced a greater weight loss
(absolute difference, approximately 4 percent) than did the conventional
diet for the first six months, but the differences were not significant at
one year. The low-carbohydrate diet was associated with a greater
improvement in some risk factors for coronary heart disease. Adherence was
poor and attrition was high in both groups. Longer and larger studies are
required to determine the long-term safety and efficacy of low-carbohydrate,
high-protein, high-fat diets. Copyright 2003 Massachusetts Medical Society"

Hypocaloric high-protein diet improves glucose oxidation and spares lean
body mass: comparison to hypocaloric high-carbohydrate diet.

"In conclusion, our experience suggests that (1) a hypocaloric diet
providing a high percentage of natural protein can improve insulin
sensitivity; and (2) conversely, a hypocaloric high-polysaccharide-CHO diet
decreases insulin sensitivity and is unable to spare muscle tissue."

Weight reduction with a high protein, low carbohydrate, calorie-restricted
diet: effects on blood pressure, glucose and insulin levels.
Nobels F, van Gaal L, de Leeuw I.
"We can conclude that: (1) changes in blood pressure are always accompanied
by changes in the same direction of one or more of the parameters of glucose
homeostasis, which suggests a common link; (2) The dietary approach to
obesity therapy successfully lowers blood pressure and helps to rectify the
abnormalities in glucose metabolism."

An Isoenergetic Very Low Carbohydrate Diet Improves Serum HDL Cholesterol
and Triacylglycerol Concentrations, the Total Cholesterol to HDL Cholesterol
Ratio and Postprandial Lipemic Responses Compared with a Low Fat Diet in
Normal Weight, Normolipidemic Women.

"In normal weight, normolipidemic women, a short-term very low carbohydrate
diet modestly increased LDL-C, yet there were favorable effects on
cardiovascular disease risk status by virtue of a relatively larger increase
in HDL-C and a decrease in fasting and postprandial triaclyglycerols"
A hypocaloric high-protein diet as primary therapy for adults with
obesity-related diabetes: effective long-term use in a community hospital.
Fitz JD, Sperling EM, Fein HG.
"This hypocaloric high-protein diet thus appears to be a generally
successful means of weaning obese diabetic adult patients from insulin. This
can be done rapidly, safely, and permanently in the community. Such diet
therapy appears to require minimal laboratory and hospital resources that
are available to all health care providers."

concluded that a high protein diet is a beneficial therapy for mild diabetic

renal function in well-trained athletes as indicated by the measures of
renal function used in this study"
