Aim. To investigate the effects of weight loss during an 8-week very low carbohydrate diet (VLCD) on improvement of metabolic parameters, adipose distribution and body composition, and insulin resistance and sensitivity in Chinese obese subjects.Methods. Fifty-three healthy obese volunteers were given an 8-week VLCD. The outcomes were changes in anthropometry, body composition, metabolic profile, abdominal fat distribution, liver fat percent (LFP), and insulin resistance and sensitivity.Results. A total of 46 (86.8%) obese subjects completed the study. The VLCD caused a weight loss of−8.7±0.6 kg (mean ± standard error (SE),P<0.0001) combined with a significant improvement of metabolic profile. In both male and female, nonesterified fatty acid (NEFA) significantly decreased (−166.2±47.6 μmol/L,P=0.001) andβ-hydroxybutyric acid (BHA) increased (0.15±0.06 mmol/L,P=0.004) after eight weeks of VLCD intervention. The significant reductions in subcutaneous fat area (SFA), visceral fat area (VFA), and LFP were−66.5±7.9 cm2,−35.3±3.9 cm2, and−16.4±2.4%, respectively (allPvaluesP<0.0001). HOMA IR and HOMAβsignificantly decreased while whole body insulin sensitivity index (WBISI) increased (allPvaluesP<0.001).Conclusion. Eight weeks of VLCD was an effective intervention in obese subjects. These beneficial effects may be associated with enhanced hepatic and whole-body lipolysis and oxidation.

Abstract Objective: Assessing relationship between low carbohydrate diet (LCD) score and metabolic syndrome (Mets) in Iranian adults. Design: Cross-sectional study Setting: Yazd Health Study and Taghzieh Mardom-e-Yazd study. Participants: Data of 2074 participants were used. Dietary intakes were assessed by a validated semi-quantitative food frequency questionnaire. LCD score was calculated for each person by summing up the assigned scores to deciles of energy percentages from macronutrients. Mets was evaluated using National Cholesterol Education Program Adult Treatment Panel III. Eventually, association between LCD score and Mets was examined using logistic regression. Results: Total Mets prevalence was approximately 40.5%. After adjustment for confounders, subjects in the higher quartile of LCD score had a significant lower chance of Mets versus lower quartile among all participants (Q4 versus Q1: OR: 0.68, 95% CI: 0.50-0.92) and separately in men (Q4 versus Q1: OR: 0.54, 95% CI: 0.34-0.86) and women (Q2 versus Q1: OR: 0.53, 95% CI: 0.34-0.82). Furthermore, more LCD adherence in men reduced abdominal obesity by 47% (Q3 versus Q1OR: 0.53, 95% CI: 0.28-0.99). Low HDL cholesterol was also observed both in the highest quartile of LCD score in all participants (OR: 0.74, 95% CI: 0.56-0.99) and separately in men (OR: 0.63, 95% CI: 0.40-0.98) versus the first quartile. Conclusions: More adherence to LCD might be related to lower chance of Mets and some of its components such as low HDL cholesterol and abdominal obesity specially in men. Further studies are required to confirm the findings.

The short-term effects of high-protein/low-carbohydrate diet on aminopeptidase N activity were studied in the brush-border membranes of proximal jejunum and proximal ileum of adult rats. The animals were starved overnight and re-fed for 15 h either with a standard diet (20% protein, 55% carbohydrate, in terms of energy content) or with a high-protein/low-carbohydrate diet of equal energy content (70% protein, 5% carbohydrate). All rats consumed similar amounts of diet, and measurements were made 15 h after initiation of re-feeding. In the proximal jejunum a slight increase in aminopeptidase activity was observed after the high-protein intake. In contrast, considerable stimulation (52%) of the enzyme specific activity was obtained in the proximal ileum. This increase in ileal aminopeptidase activity was more prominent in the mature cells of the upper villus. To determine if the increase of aminopeptidase activity was due to an increased amount of enzyme protein, rocket immunoelectrophoresis was performed with detergent-solubilized brush-border protein from ileum on agarose gels containing anti-(rat brush-border) antiserum. When the same amount of enzyme activity was loaded on the gels, the peaks of immunoprecipitate for aminopeptidase were similar for animals fed on a standard or a high-protein diet. When the same amount of protein was loaded, the peak of immunoprecipitate for aminopeptidase was higher (81%) after a high-protein diet. These results showed that the high protein intake evoked an increase in aminopeptidase activity, with a concomitant increase in the amount of immunoreactive protein.
