Abstract

Purpose

The purpose of this paper is to assess eight weeks individualized balanced low-calorie diet on anthropometric measurements and body composition in apparently healthy obese women.

Design/methodology/approach

Forty apparently healthy obese women (body mass index: 27.5-40 kg/m2 and age: 18-40 years) were recruited from the nutrition clinic in the north-west of Iran, Ardabil city. Anthropometric measurements and body composition analysis were done at baseline and after the intervention.

Findings

During eight weeks, individualized balanced low-calorie diet resulted in a significant decrease in body weight (−4.0 ± 0.3 kg, p < 0.001), body mass index (−1.6 ± 0.1 kg/m2, p < 0.001), waist circumference (−2.9 ± 0.3 cm, p < 0.001), waist-to-hip ratio (−0.01 ± 0.004, p = 0.001), waist-to-height ratio (−0.02 ± 0.002, p < 0.001), per cent body fat (−1.1 ± 0.2 per cent, p < 0.001), fat mass (−2.5 ± 0.3 kg, p < 0.001), visceral fat level (−0.8 ± 0.1, p < 0.001), visceral fat area (−11.3 ± 2.3 cm2, p < 0.001), trunk mass fat (−1.2 ± 0.1 kg, p < 0.001), left arm mass fat (−0.2 ± 0.03 kg, p < 0.001), right arm mass fat (−0.2 ± 0.03 kg, p < 0.001), left leg mass fat (−0.4 ± 0.1 kg, p < 0.001), right leg mass fat (−0.4 ± 0.05 kg, p < 0.001), abdominal volume index (−1.1 ± 0.1 m2, p < 0.001), conicity index (−0.007 ± 0.002 m2/3/kg1/2, p = 0.001) and body adiposity index (1.0 ± 0.1 per cent, p < 0.001).

Research limitations implications

The limitation concerns the generalizability to the general population of obese women. Future studies should take sex differences into consideration. These studies may focus on the long-term benefits.

Originality/value

Balanced low-calorie diet-induced moderate weight loss alone may represent an effective strategy for reducing metabolic risk factors among obese women.

Abstract

Purpose

Background/Objectives: Protein-based meal replacements (MR) with viscous soluble fibre are known aids for weight loss. This study aims to compare the effects of new whey and vegan MR containing different amounts of PGX (PolyGlycopleX) on weight loss over 12 weeks, along with a calorie-restricted diet.

Design/methodology/approach

Subjects/Methods: Sixty-eight healthy adults of both sexes (53 women; 15 men; average age 47.1 years; BMI 31 ± 7.1 kg/m2 and weight 85.05 ± 23.3 kg) were recruited. Participants consumed a whey or vegan MR twice/d (5–10 g/day PGX) with a low-energy diet (1,200 kcal/day), over 12 weeks. Weight, height, waist and hip circumference were recorded (four time periods).

Findings

Results: Forty-four participants completed the study. Results showed significant reductions in average body weight and at week 12, whey group was [−7.7 kg ± 0.9 (8.3%), p < 0.001] and vegan group was [−4.5 kg ± 0.8 (6.2%), p < 0.001)]. All participants (n = 44; BMI 27 to 33 kg/m2) achieved significant reductions in body measurements from baseline to week 12; p < 0.001. Conclusions: Supplementation of protein-based MR with PGX and a balanced, low-energy diet, appears to be an effective approach for short-term weight loss.

Research limitations/implications

As the authors were evaluating if the MR as a whole (i.e. with PGX) caused weight loss from baseline over the 12 weeks, no comparators, i.e. just the MR without PGX, were used. Formulation of these new MRs resulted in a whey product with 5 g PGX and a vegan product with 2.5 g PGX. Only 2.5 g PGX could be formulated with the vegan protein due to taste and viscosity limitations. Study participants were not randomized and no control groups (e.g. no MR or MR without PGX but with energy restricted diet) were used. Furthermore, it is not clear whether the sort of protein alone or the combination with a higher amount of PGX (whey with 5 g PGX/serving vs vegan with 2.5 g PGX/serving) has contributed to these significant greater weight-loss effects. This was something the authors were testing, i.e. could only 2.5 g PGX/serving have an effect on weight loss for a vegan MR. These limitations would be somethings to evaluate in a subsequent randomized controlled study. Hence, the results of this study may serve as a good starting point for further sophisticated randomized controlled trials that can demonstrate causality – which the authors acknowledge as one of the fundamental limitations of an observational study design. Participants tracked their calories but adherence and compliance were self-assessed and they were encouraged to keep their exercise routine consistent throughout the study. Hence, these are further limitations. No control group was used in this study to observe the effect of the dietary intervention and/or physical activity on weight loss alone. However, a goal of the authors was to keep this study as close to a real-life situation as possible, where people would not be doing any of these measurements, to see if with minimal supervision or intervention, people can still lose weight and alter their body composition. Furthermore, differences in gender and the corresponding weight loss effects in response to MR-protein-based treatments could be evaluated in follow-up studies.

Practical implications

This study indicates that the consumption of protein-based (animal, whey or plant, pea protein) MR incorporating the highly soluble viscous PGX is beneficial for weight loss when combined with a healthy-balanced, calorie-restricted diet. MRs at either 2.5 g or 5 g per serving (RealEasyTM with PGX) proved to be a highly effective as a short-term solution for weight loss. The observed results are encouraging, however, further long-term studies (i.e. randomized clinical trials RCT) are needed to confirm the clinical relevance. RCTs should focus on the individual effects of PGX and/or the different protein sources used in MRs, on weight loss and the maintenance of the reduced body weight, and should measure detailed blood parameters (lipid profiles, glucose etc.) as well as collect detailed exercise and food consumption diaries.

Originality/value

To the authors’ knowledge, this is the first study comparing a whey versus vegan, (as pea) protein-based MR that is supplemented with fibre PGX; thus, this work adds information to the already existing literature on fibre (such as PGX) and MRs regarding their combined weight loss effects. The purpose of this study was to observe if the novel protein-based (either whey or vegan versions) MR RealEasyTM with PGX at 2.5 or 5 g in addition to a calorie-restricted diet (total of 1,200 kcal/day) would aid in weight loss in individuals over a 12-weeks period. Adding increasing amounts of whey protein and soluble fibre can help reduce subsequent ad libitum energy intake which could help adherence to energy restricted diets, but whether similar effects are seen with vegan protein is unclear – this study does aim to address this.

Abstract

Purpose

This paper aims to evaluate the prevalence of general obesity (GO) and abdominal obesity (AO) in the north-west of Iran and investigate the association with food choices and socioeconomic status (SES).

Design/methodology/approach

In this cross-sectional study, 500 subjects aged ≥ 18 years were studied. Data on their basic characteristics, anthropometric measurements, dietary habits and physical activity were collected. The authors examined the association between GO and AO with SES and food choices using multiple logistic regression analysis.

Findings

The prevalence of GO and AO was 26.6 and 43.4%, respectively. A positive association was observed between age and GO (p for trend <0.001) and AO (p for trend 0.005) in both sexes. However, a negative correlation was detected between education and income with GO and AO (p for trend <0.001). Two or more servings of fruit consumption a day were associated with lower odds of obesity. It was observed that the odds of GO and AO decreased by three or more servings of daily fruit. The consumption of dairy products in two or more servings a day led to a reduction in odds of GO and AO. The consumption of five or more servings of legumes, beans and nuts a week was associated with lower odds of GO and AO.

Originality/value

Educational attainment, greater income and a higher intake of some specific food groups were associated with lower odds of obesity in the area. More population-based investigations are required to develop effective preventive strategies to control the status of being overweight and obesity in different regions.

Abstract

Three events of significance to this country took place in 1899 – the British Food Journal was launched, Australia retained the Ashes, and the Boer War hostilities commenced. If challenged on the order of their importance, cricketers and Empire‐builders may be excused their preference. However, looking at it purely from the standpoint of pro bono publico, the dispassionate observer must surely opt for the birth of a certain publication as being ultimately the most beneficial of the three.

Abstract

Purpose

The COVID-19 pandemic has profound implications on the food and nutritional security of millions of households. The study assessed the impacts of the COVID-19 pandemic on diet diversity, calorie consumption and intake of essential nutrients based on the gender of the households.

Design/methodology/approach

Mixed-design ANOVA and logistic regression were used to analyze the collected data from 260 female- and 463 male-headed households through an online survey in Pakistan.

Findings

The outcomes revealed that the diet diversity of female households was affected more due to the COVID-19 compared to male households. The decline in daily nutrients' (protein, phosphorus, zinc, iron and iodine) intake during the COVID-19 was also greater for female-headed households than male-headed households. The share of all food groups in daily calorie and nutrient provision decreased significantly during the COVID-19 for both types of households. The share of meat and meat products declined more for female-headed households compared to male-headed households. The share of perishable commodities in calorie provision to female and male households decreased 2% during the COVID-19 compared to the normal period. Small- and medium-sized female and male households were less likely to experience worsened diet diversity than large-sized households during the COVID-19. Low-income compared to medium- and high-income female and male households were more likely to report declined food diversity during the COVID-19.

Research limitations/implications

The data used in this study were collected through an online survey due to public health measures imposed in the country.

Originality/value

Despite the emergence of literature on the implications of the pandemic on food security, the studies related to the gender-based impacts of COVID-19 on diet diversity and nutritional intakes of necessary nutrients are still non-existent. The current study will add to the literature by filling this gap.

Abstract

Purpose

Calorie restricted diets are known to improve health and promote healthy aging. This happens because of controlled inflammation and metabolism in the body. This study aims to evaluate the differences in anthropometric and biochemical parameters in Sprague Dawley (SD) rats because of consumption of a calorie restricted diet.

Design/methodology/approach

The study divided SD rats (n = 15) into 3 groups consuming high calorie intake (HCI), medium calorie intake and low calorie intake (LCI). Anthropometric parameters were determined through measurement of abdominal circumference (AC), thoracic circumference (TC), body length and body weight (BW). Biochemical parameters analyzed in this study were fasting blood glucose level and full blood lipid profile. Nutritional status was obtained based on food consumption, energy intake (EI) and food efficiency rate. Measurements were taken for a period of four weeks.

Findings

Analysis on anthropometric parameters indicates a significant difference in mean BW between HCI (230.44 ± 1.47 g) and LCI (188.54 ± 1.50 g). There is a significant difference in abdominal TC ratio (p < 0.001; F = 13.599) in the LCI group (1.01 ± 0.00714) compared to the HCI group (1.04 ± 0.00858). Post hoc for nutrition parameters indicates a significant difference in mean EI between HCI (9.71 ± 0.006 kJ) and LCI (3.21 ± 0.001 kJ). There is a significant effect (p < 0.0001; F = 3042872.02) of EI on rats in all three groups. HDL levels were significantly higher (p < 0.0001; F = 1536.89) in the LCI group (68.60 ± 0.55 mg/dL) compared to the HCI group (49.40 ± 0.55 mg/dL). The Pearson’s correlation results show a strong positive correlation in EI with BW (p < 0.01; r = 0.988), AC (p < 0.01; r = 0.970) and body mass index (p < 0.01; r = 0.972).

Originality/value

Low calorie diet has been proven to affect anthropometric development and has shown improvements in biochemical parameters of the rats. This may result in healthy aging which could prevent later-life diseases.

Abstract

Diets, notably diets aimed at weight reduction, appear regularly in women’s general interest magazines. Recently there has also been an increase in publications aimed at health promotion or slimming, and in the availability of “slimming aids”. The efficacy of some of these has been questioned, and concern expressed over the nutritional adequacy of some diets. Investigates the nutritional adequacy of nine diets drawn from a variety of publications. Most diets were aimed at weight loss, but some were promoted as a “new way of life”, e.g. food combining. Energy levels supplied by all diets were below current recommendations, thus weight reduction would be the result of low energy intakes. Overall, the nutritional value of the diets was reasonable.The main concern was low iron intakes supplied by the Food Combining for Health diet, where the diet is followed for long periods.

Abstract

Purpose

Healthy diet and lifestyle have been shown to be important for obese patients in the management of diet‐related diseases especially in the improvement of cardiovascular disease risk indicators. The purpose of this paper is to determine the effects of a calorie‐restricted low‐fat diet on body weight, cardiovascular disease risk and liver function indicators in an obese, cardiology outpatient with type II diabetes.

Design/methodology/approach

A male, obese cardiology outpatient was assigned to a calorie‐restricted (6,694.4 kJ/d) low‐fat (not to exceed 20 per cent of total energy intake) diet for 12 weeks. His body mass index (BMI), blood pressure (BP), pulse rate, fasting glucose, total cholesterol, triglyceride, low‐density lipoprotein cholesterol, high‐density lipoprotein (HDL) cholesterol, alanine aminotranseferase, aspartate aminotranseferase (AST) concentration and TC/HDL ratio were measured prior to the start of the diet and during weeks four, eight and 12 of the diet.

Findings

The patient found it difficult making changes to his diet and only reduced his weight by 1 kg. He significantly reduced his serum triglyceride by about 20 per cent, TC/HDL ratio by 13 per cent and fasting blood glucose concentration by 31 per cent. However, there was no significant change in his BP, pulse rate, total and LDL cholesterol concentration. He also reduced his AST concentration by 20 per cent and alanine aminotranseferase (ALT) by 19 per cent.

Originality/value

This paper usefully shows how healthier food choices involving increased intake of fruits and vegetables and restricted intake of total and saturated fat reduced the risk of cardiovascular death in a male cardiology outpatient with type II diabetes.

Abstract

Encouraging socio‐economic development in developing countries has resulted in many changes in the lifestyle of communities. Changes in dietary patterns are one of the main outcomes from the rapid socio‐economics advancement, for example excessive intake of fat, high‐protein diet (animal protein), salt and preservatives. Chronic diseases such as diabetes, coronary artery disease, hypertension and cancer are mostly related to diet. With the community becoming more nutrition and health conscious, one of the challenges faced is to make sure that the information and knowledge on diet and healthy lifestyle gets across to the community. This paper presents a model of web‐based diet system (WebDIET) that attempts to make diet information and menu plans that are customised to local preference more accessible via the use of Internet. The system is to be used by dieticians who serve as administrators and the public who are the end users. The dietary standard adapted in developing the system is Recommended Dietary Allowances (RDA) for Malaysia. The Malaysian Dietary Guidelines was also referred as it emphasises on Malaysian diet. The system consists of six modules namely Authentication Module, Menu Plan Module, Diabetic Menu Plan Module, Food Selection Module, Disease Info Module and Feedback Module. Diabetic menu plan module models the reasoning process employed by dieticians in suggesting menu plans. The planning task is solved using an artificial intelligence technique through the case‐based reasoning (CBR) approach. CBR, generally describes, the process of solving the current problem based on the proposed solution of similar problems in the past. Nearest Neighbour Algorithm was used to compute the similarities in weighted average. Tools used for the development of the system are Microsoft Visual Interdev, Microsoft FrontPage 2000, while HTML, VBScript and JavaScript are the scripting languages used to develop the system.

Abstract

Purpose

The purpose of the paper is to determine the effects of a hypocaloric diet with a low-glycaemic index (GI) on weight loss and postprandial blood glucose and assess both the satiety and palatability of the diet.

Design/methodology/approach

A clinical trial was conducted with ten women (mean age: 38.8±11.3 years; body mass index: 27.2±3.5 kg/m2) submitted to a hypocaloric diet, assessments were performed at baseline and after seven days of treatment.

Findings

Significant reductions were found in body weight (1.1±0.7 kg; p=0.001), triccipital skinfold (2.87±3.24 mm; p=0.021) and waist circumference (3.6±4.8 cm; p=0.041). Mean fasting and postprandial blood glucose values were 88.7±6.1 mg/dL and 91.6±9.6 mg/dL, respectively. Responses regarding satiety and palatability of the low-GI diet were predominantly “extremely satisfied” and “I liked it very much,” respectively, for all meals and throughout all seven days of the study.

Originality/value

The present study demonstrated the benefits of a low-GI diet with regard to weight loss, blood glucose control and satiety. The diet proved to be palatable, which could favor compliance with long-term treatment.
