ObjectiveTo measure the energy content of frequently ordered meals from full service and fast food restaurants in five countries and compare values with US data.DesignCross sectional survey.Setting223 meals from 111 randomly selected full service and fast food restaurants serving popular cuisines in Brazil, China, Finland, Ghana, and India were the primary sampling unit; 10 meals from five worksite canteens were also studied in Finland. The observational unit was frequently ordered meals in selected restaurants.Main outcome measureMeal energy content, measured by bomb calorimetry.ResultsCompared with the US, weighted mean energy of restaurant meals was lower only in China (719 (95% confidence interval 646 to 799) kcal versus 1088 (1002 to 1181) kcal; P<0.001). In analysis of variance models, fast food contained 33% less energy than full service meals (P<0.001). In Finland, worksite canteens provided 25% less energy than full service and fast food restaurants (mean 880 (SD 156) versus 1166 (298); P=0.009). Country, restaurant type, number of meal components, and meal weight predicted meal energy in a factorial analysis of variance (R2=0.62, P<0.001). Ninety four per cent of full service meals and 72% of fast food meals contained at least 600 kcal. Modeling indicated that, except in China, consuming current servings of a full service and a fast food meal daily would supply between 70% and 120% of the daily energy requirements for a sedentary woman, without additional meals, drinks, snacks, appetizers, or desserts.ConclusionVery high dietary energy content of both full service and fast food restaurant meals is a widespread phenomenon that is probably supporting global obesity and provides a valid intervention target.

Short-term RD was more efficient than CD regarding quick weight loss and waist circumference reduction, which may favor gastroplasty. Also, RD did not lead adverse metabolic effects.

Objective: Olanzapine is an atypical antipsychotic drug used to treat schizophrenia. Some of the adverse effects related to its use are obesity, hyperlipidemia, type 2 diabetes and hypertension, which may result in development of metabolic syndrome. This study aimed to investigate a possible increase in some anthropometric and biochemical parameters, and the existence of any correlation between them in Brazilian patients with schizophrenia treated with olanzapine in the mid term. Methods: Thirty subjects with schizophrenia were evaluated, 16 women and 14 men, aged between 18 and 47 years. All patients underwent blood collection and anthropometric measurements at four different times during 12 months of follow up; thus each patient was his or her own control. Results: Evaluation of some anthropometric measurements showed significant differences when comparing the mean values obtained in each of the different data collection times (p < 0.05). However, the biochemical indicators of development of metabolic syndrome measured in our study did not show the same rate of increment, with only the total cholesterol and glucose levels presenting statistically significant changes (p < 0.05), but without the same magnitude of weight change. Conclusion:We conclude that medium-term treatment with olanzapine promoted a substantial weight gain and increased visceral fat, while the metabolic profile did not show the same magnitude of change, suggesting a dissociation between weight gain and blood parameters, despite the severe weight gain observed among subjects evaluated.

BACKGROUND: During weight gain, most of the excess adipose tissue accumulates in the trunk. This alters the body shape and makes collection of anthropometric measurements, especially waist circumference (WC), difficult. OBJECTIVE: To evaluate the sensitivity and applicability of additional abdominal measurements in order to assess body composition of obese women. METHODS: A total of 30 women between 20 and 50 years of age and BMI above 30 kg/m² were assessed. Three WC measurements, were performed: at the umbilical scar designated as WC1 and at 8 and 16 cm above the umbilical scar, designated as WC2, and WC3 respectively. The correlation (r) between these anthropometric measurements and their sum was assessed against the parameters fat mass (FM), free fat mass (FFM), body fat percentage (%BF), and trunk fat percentage (%TF), obtained by total and trunk segmental bioelectric impedance analysis (BIA) as well as by the golden standard total and trunk dual energy X-ray absorptiometry (DXA). RESULTS: The measurements WC1, WC2, WC3, and their sum correlated strongly and moderately with the parameters FM, FFM, and %BF in total BIA and in both total DXA and trunk DXA. CONCLUSION: The results demonstrated a robust correlation between the sum of the three WC measurements and total and trunk DXA in obese women suggesting that such measurements may be a good indicator of body and trunk fat in women, actually superior to BIA results. The use of these three measurements may be an alternative for the assessment of body and trunk fat, in those cases in which the body shape due to adipose tissue trunk accumulation makes accurate classical measurement (WC1) difficult.
