Low calorie diet samples
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. Abstract Background Trials comparing the effectiveness and safety of weight-loss diets are frequently limited by short follow-up times and high dropout rates. The criteria for eligibility were an age of 40 to 65 years and a body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) of at least 27, or the presence of type 2 diabetes (according to the American Diabetes Association criteria 18 ) or coronary heart disease, regardless of age and BMI. Abstract Background Despite the popularity of the low-carbohydrate, high-protein, high-fat (Atkins) diet, no randomized, controlled trials have evaluated its efficacy. Results The rate of adherence to a study diet was 95. Longer and larger studies are required to determine the long-term safety and efficacy of low-carbohydrate, high-protein, high-fat diets. The low-carbohydrate diet was associated with a greater improvement in some risk factors for coronary heart disease.

Methods Eligibility and Study Design We conducted the trial between July 2005 and June 2007 in Dimona, Israel, in a workplace at a research center with an on-site medical clinic.
Adherence was poor and attrition was high in both groups. Professional contact was minimal to replicate the approach used by most dieters. 6% at 2 years. Low-carbohydrate, high-protein, high-fat diets have become increasingly popular, and many best-selling diet books have promoted this approach. ) Full Text of Discussion. Figure 2 Percentage of Subjects with a Positive Urinary Ketone Concentration, According to Whether They Were on the Low-Carbohydrate Diet or the Conventional (Low-Calorie, High-Carbohydrate) Diet. The more favorable effects on lipids (with the low-carbohydrate diet) and on glycemic control (with the Mediterranean diet) suggest that personal preferences and metabolic considerations might inform individualized tailoring of dietary interventions. gov number, NCT00160108. 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. 8,9 The Atkins diet, originally published in 1973 and again in 1992 and 2002, may be the most popular of these diets. The Mediterranean-diet group consumed the largest amounts of dietary fiber and had the highest ratio of monounsaturated to saturated fat (P Full Text of Results. Conclusions Mediterranean and low-carbohydrate diets may be effective alternatives to low-fat diets. 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 participants were randomly assigned within strata of sex, age (below or above the median), BMI (below or above the median), history of coronary heart disease (yes or no), history of type 2 diabetes (yes or no), and current use of statins (none, The members of each of the three diet groups were assigned to subgroups of 17 to 19 participants, with six subgroups for each group.
