Dr. John Daugirdas, an experienced and well-respected Chicago-based kidney specialist, has developed a promising new way to lose weight. The QOD Diet His new, highly readable book, The QOD Diet describes a weight loss method based on eating regular amounts of food one day, and then restricting food every other day while taking in key minerals to keep up one’s energy level. Here is a new approach to dieting backed by scientific thinking and experience. The QOD diet is less onerous than other diets. Because one reduces food intake only every other day, one can always look forward to a day of normal eating the next day. Still, most people have trouble in markedly lowering the amount of food they eat even for one day. Dr. Daugirdas believes that feeling poorly when not eating much is due to loss of sodium and other minerals by the kidney. His idea is, that by taking in sodium, potassium, and other minerals plus high-biologic-value protein, while eating only a small number of calories, you can continue to feel well and keep up your energy level for a day, even when you are eating only 400 calories. So his idea is to eat about 400 calories for one day (which he calls the OFF day) , and then 2000-2600 calories (depending on gender, age, height, and activity level) the next day, (which he calls it the ON day). So average calorie intake is only 1200-1500 calories per day – the amount that people eat on most weight loss diets. He gives guidelines on what to eat on the ON days (healthy foods, not too much sugar or junk foods, in other words, a balanced diet) and how to eat on the OFF days (mostly vegetables, tomato/vegetable juice, orange juice, and yogurt). He identifies many foods that are particularly good for the OFF days, all or most of which can be found in local grocery stores. In addition to letting people eat well every other day (without overdoing it), the QOD diet may have a metabolic advantage. Normally, when a person goes on a diet, survival and starvation mechanisms kick in and fuel is burned more efficiently. Basically, the body learns to get by with less. At first dieters lose a few pounds, but then weight loss often ceases, and people usually gain back much of their lost weight soon after resuming normal eating. With the QOD diet, the body still senses a normal amount of food coming in every other day, and so it doesn’t feel the need to go into protection mode and drop the metabolic rate. Dr. Daugirdas believes that this dietary program is not for everyone. It is not for people who have a tendency to eating disorders (binge eating or anorexia in particular), nor for people with serious medical problems, including diabetes, heart disease, hypertension, or stroke. But it is a way for healthy people to lose a moderate amount of weight and then to maintain their weight.

интересно! А вот кто бы мне объяснил на пальцах разницу в этих двух статистически методах? Considerations in the Statistical Analysis of Hemodialysis Patient Survival Christos Argyropoulos *1, Chung-Chou H. Chang {dagger}{ddagger}, Laura Plantinga {sect}, Nancy Fink {sect}||, Neil Powe {sect}||¶, and Mark Unruh * *Renal-Electrolyte Division, University of Pittsburgh Medical Center, and {dagger}General Internal Medicine Division, School of Medicine, and {ddagger}Department of Biostatistics, Graduate School of Public Health, University of Pittsburgh, Pittsburgh, Pennsylvania; and Departments of ||Medicine, {sect}Epidemiology, and ¶Health Policy Management, Johns Hopkins University, Baltimore, Maryland E-mail: argyropoulosc@upmc.edu . Abstract The association of hemodialysis dosage with patient survival is controversial. Here, we tested the hypothesis that methods for survival analysis may influence conclusions regarding dialysis dosage and mortality. We analyzed all-cause mortality by proportional hazards and accelerated failure time regression models in a cohort of incident hemodialysis patients who were followed for 9 yr. Both models identified age, race, heart failure, physical functioning, and comorbidity scores as important predictors of patient survival. Using proportional hazards, there was no statistically significant association between mortality and Kt/V (hazard ratio 0.72; 95% confidence interval 0.45 to 1.14). In contrast, using accelerated failure time models, each 0.1-U increment of Kt/V improved adjusted median patient survival by 3.50% (95% confidence interval 0.20 to 7.08%). Proportional hazard models also yielded less accurate estimates for median survival. These findings are consistent with an additive damage model for the survival of patients who are on hemodialysis. In this conceptual model, the assumptions of the proportional hazard model are violated, leading to underestimation of the importance of dialysis dosage. These results suggest that future studies of dialysis adequacy should consider this additive damage model when selecting methods for survival analysis. Accelerated failure time models may be useful adjuncts to the Cox model when studying outcomes of dialysis patients.

But it is a way for healthy people to lose a moderate amount of weight and then to maintain their weight. Наверное доктор Дагирдас изобрел диету для нефрологов гемодиализа- которые явно попадают под данное определение: healthy people которым необходимо немного to lose a moderate amount of weight and then to maintain their weight. Диета подозрительно совпадает с расписанием диализа- 3 раза в неделю.....
