Many over- weight people overeat in the evening. We hypothesized that ingesting protein prior to the eve- ning meal may limit successive calorie intake and generate weight loss. Aims: To explore whether protein pre-load before the evening meal will lead to weight loss compared to eating as usual. Methods: 129 adults with a Body Mass Index (BMI) ≥25 reporting eating large evening meals were randomized to either consume a 20 g protein bar 30 minutes before their evening meal daily for two weeks (Protein pre-loading (PP) arm) or not (No protein pre-loading (NP) arm). Hunger ratings were recorded, immediately prior to each evening meal. Participants returned at the end of weeks one and two to provide their weight and rating of hunger and any changes in evening food consumption since baseline. Results: There was no significant difference in weight loss between the study arms (Week1 PP: -0.13 kg, (SD=0.74) vs. NP: -0.06 kg, (SD=0.75), not significant (NS); Week2 PP: +0.06 kg, (SD=0.82) vs. NP: -0.005 kg, (SD=0.82), NS). Participants in the PP arm reported less hunger before evening meals than those in the NP arm (Week1: 4.97 (SD=0.94) vs. 3.72(SD=0.65), p<.001; Week2: 4.95 (SD=0.94) vs. 3.69(SD=0.71), p<.001). They also reported eating less at their evening meals (Week1: 2.59(SD=0.53) vs. 2.11(SD=0.54), p<.001; Week2: 2.63(SD=0.49) vs. 2.10(SD=0.50), p<.001). Conclusion: Consuming 20 g of protein before the evening meal reduced hunger and self- reported food intake in the evening, but had no effect on weight.","PeriodicalId":79415,"journal":{"name":"Obesity research","volume":"2 1","pages":"111-116"},"PeriodicalIF":0.0,"publicationDate":"2016-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67443544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Daily Calcium Intervention for a Weight-Loss Program Resulted in More Significant Decreases in Body Weight, BMI, Body Fat Mass, and Body Fat Percentage","authors":"Yen Ling Chen, Yi-Chun Chen, Jung-Su Chang, Jonathan C.

Chien","doi":"10.17140/OROJ-2-112","DOIUrl":"https://doi.org/10.17140/OROJ-2-112","url":null,"abstract":"The purpose of this study was to assess of calcium intervention on the effectiveness of a weight-loss program for obese people. All subjects had an initial BMI (body mass index) >24 kg/m 2 and low calcium diet (<500 mg/d). Forty-two healthy overweight or obese people were randomly and equally divided into two groups: a Hi-Ca group (female: 16, male: 5) and a control group (female: 16, male: 5). In the Hi-Ca group, we provided two bottles of Hi-Ca drinks per day and a low energy diet (energy: 1200 kcal, carbohydrate: 55%, fat: 25%, protein: 20%) for eight weeks. In the control group, we only provided the low energy diet for eight weeks. We measured three-day food records, anthropometric and blood biochemical data at Weeks 0 and 8. Calcium intake was 964.5±75.5 mg in the Hi-Ca group and was 353.7±96.6 mg in the control group (p<0.05). After eight weeks, results showed the loss of body weight (-6.9±3.3 kg, p<0.05), BMI (-2.7±1.1 kg/m 2 , p<0.01), body fat mass (-5.7±2.7 kg, p<0.05), body fat percentage (-4.4±1.9 %, p<0.002) and TC/HDL-C (-0.4±0.6, p<0.05) in the Hi-Ca group were significantly different from those of the control group at eight weeks. In the lipid profile, serum cholesterol, triglycerides and LDL-C concentration were significantly decreased compared with Week 0. The serum PTH (parathyroid hormone) levels in the Hi-Ca group were significantly lower compared with baseline (-5.3±10.4 pg/mL, p<0.05), which showed that the concentration of PTH and calcium intake are negatively correlated, and indicate that a high- calcium low-energy diet resulted in more significant decreases in body weight, BMI, body fat mass, and body fat percentage. Therefore, a high calcium diet increases the effectiveness of an energy-restricted diet for weight loss in overweight people.","PeriodicalId":79415,"journal":{"name":"Obesity research","volume":"2 1","pages":"73-80"},"PeriodicalIF":0.0,"publicationDate":"2015-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67443499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A study was un- dertaken to examine the relationship between cardiovascular diseases and nutritional status in Pakistani women. Methods: A case-control study was carried out in the Outpatients department (OPD) of the Cardiology Unit, Rehman Medical Institute (RMI), Peshawar, Khyber Pakhtunkhwa, Pakistan. The inclusion criteria for selection of cases were females having complaints of myocardial infarction and free from all other infectious and chronic diseases. Forty three cases and 43 con- trols were selected for the study. Subjects were interviewed for their medical history, dietary in- take demographic and socio-economic characteristics. Weight, height measurements and blood samples from both the cases and controls were taken for assessing their nutritional status. Data were analyzed using Student's t-test, Chi-square test, univariate and multivariate unconditional logistic regression to study the relationship between different variables. Results: The results revealed that the cases had a significantly (p 0.05) differences in the mean weight, height, BMI, serum ferritin and haemoglobin concentrations between the cases and controls. High prevalence of overweight and obesity was found in both cases (67.4%) and controls (81.4%). Cases had a significantly lower mean dietary energy, protein, carbohydrates, and fat intake than the controls but there was no significant difference (p>0.05) in the mean iron intake between the cases and controls. Results of logistic regression showed no significant association between the dependent (CVD) and independent variables (age, diastolic blood pressure, BMI, exercise, family history, family type, family size, haemoglobin, ferritin, carbohydrates and protein). Conclusions: The study does not reveal significant relationship between the CVDs and nutri - tional status. The prevalence of overweight and obesity in women was found to be alarmingly high and needs to be addressed by appropriate interventions to prevent the incidence of meta- bolic syndromes and chronic diseases in population.","PeriodicalId":79415,"journal":{"name":"Obesity research","volume":"2 1","pages":"32-38"},"PeriodicalIF":0.0,"publicationDate":"2015-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.17140/OROJ-2-106","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67443459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
