The purpose of this research was to investigate the relationship between mental health, eating attitudes, and the amount of weight loss in obese and overweight individuals.

The design of the study was cross-sectional. The statistical population consisted of obese and overweight individuals who visited nutrition clinics in Rasht City, Iran. A total of 420 participants were included in the study, comprising 378 women with an average weight of 79.99 ± 15.91 kg, height of 161.67 ± 5.98 cm, age of 39.59 ± 11.15 years, and body mass index (BMI) of 30.88 ± 3.06 kg/m2, as well as 42 men with an average weight of 100.31 ± 23.59 kg, height of 175.07 ± 9.75 cm, age of 38.45 ± 11.35 years, and BMI of 32.75 ± 4.20 kg/m2. The participants were selected using convenience sampling method. Data were collected using online questionnaires that included Carner's Eating Attitudes Test (EAT) and Goldberg's General Health Questionnaire (GHQ). Data analysis was conducted using Pearson's correlation coefficient test and regression modeling in SPSS software.

There was a significant relationship between mental health (r =- 0.18, P < 0.001) and eating attitude (r = 0.10, P = 0.030) with the success rate in weight loss. The relationship between mental health dimensions, including physical condition (r =- 0.19, P < 0.001), anxiety (r =- 0.11, P = 0.018), and social function (r = -0.16, P = 0.001) was significant with weight loss. The relationship between the components of eating attitude, including oral control (r = 0.21, P < 0.001) and desire to eat (r =- 0.12, P = 0.009) with success in weight loss was significant.

Higher mental health, as well as a better level of eating attitude, was associated with greater weight loss success in obese and overweight people referred to nutrition clinics. Therefore, paying attention to these factors will increase the probability of success in weight loss.

The prevalence of overweight and obesity is increasing dramatically due to unhealthy lifestyles. This study aimed to determine the effects of six weeks of total-body resistance exercise (TRX) combined with purslane supplementation on serum levels of brain-derived neurotrophic factor (BDNF), adropin, and nesfatin in overweight girls.

In this semi-experimental study, 32 overweight female students aged 16 to 18 years (BMI > 25) from Ganaveh County, Bushehr Province, Iran, were randomly selected. The participants were divided into four groups: exercise, supplement, exercise + supplement, and placebo. The exercise groups performed TRX exercises consisting of 9 to 11 movements for six weeks, with three sessions per week, each lasting 60 minutes. Purslane supplementation was administered as two 500 mg capsules of purslane (Perpin Ala) taken daily after breakfast and lunch. Serum levels of BDNF, adropin, and nesfatin were measured using ELISA at the beginning and end of the six-week study.

The serum levels of BDNF in the exercise + supplement group showed significant differences compared to the exercise, supplement, and control groups (P < 0.05). Additionally, the serum levels of nesfatin were significantly different between the exercise + supplement group and the control group (P < 0.05). However, there were no significant differences in serum levels of adropin among the groups (P > 0.05).

The findings suggest that a combination of TRX exercises and purslane supplementation over six weeks positively affects BDNF and nesfatin levels in young girls, potentially aiding in weight reduction. Further research is needed to explore this area more comprehensively.

Physical activity has a dual effect on inflammation and the results of studies are very contradictory. The aim of this study was the interactive effect of six weeks of TRX training and oral intake of mango tree leaf extract on interleukin-12 and anterometric indices of overweight and inactive obese male students.

In a semi-experimental research, 48 overweight and inactive obese students with an age range of 20-25 years were purposefully selected and divided into 4 groups of 12: control, extract, exercise and exercise+extract. For six weeks (three sessions per week), they did TRX exercises and took 500 mg capsules containing mango leaf extract twice a day lunch and dinner. Blood sampling was done 24 hours before and 48 hours after the last training session. Interleukin-12 serum level was measured by ELISA method using human kit. Data were analyzed with dependent t-test and one-way analysis of variance and significance level less than 0.05 in SPSS-25 software (P<0.05).

A significant difference was observed in the levels of interleukin-12 in the exercise, exercise+extract and extract groups compared to the pre-test (p=0.001). The pre- and post-test differences between the groups using one-way analysis of variance on weight, fat percentage, body mass index and interleukin-12 levels showed a significant difference between the research groups (p < 0.05 between groups).

Six weeks of TRX training and consumption of mango leaf extract may be effective in reducing weight, fat percentage, body mass index and interleukin-12 serum levels. On the other hand, one of the ways to control inflammation is to do TRX exercises with mango leaf extract.

Obesity is related to an increase in free radicals and oxidative stress or a decrease in the antioxidant capacity of the body. The purpose of this study is investigate the effect of a period of functional exercises with and without chlorella vulgaris supplement on some inflammatory, lipid peroxidation and antioxidant indicators in overweight and obese men.

This was a quasi-experimental study with a pre-test-post-test design in which 40 overweight and obese men were selected randomly and divided into 4 groups (n=10 each): placebo, supplement, placebo+exercise, and supplement+exercise. Blood sampling was done in four stages to evaluate TNF-α, hs-CRP, MDA, GPx and SOD variables. Functional exercises were performed three sessions per week continued for 12 weeks, each session lasting 60 minutes. Subjects took three 300 mg Chlorella vulgaris capsules daily. Statistical analyses were performed at a significance level of p≤0.05 using SPSS version 22.

After adjusting the pre-test scores, the levels of serum TNF-α, hs-CRP, MDA, GPx and SOD in the post-test in the placebo, supplement, exercise and exercise+supplement groups had a statistically significant difference (p≤0.05). Comparing the groups showed that the level of serum TNF-α, CRP and MDA in the exercise group was significantly lower than that in the placebo group and that the serum level of GPx and SOD in exercise group was higher compared with the placebo group (p≤0.05).

According to the findings of the present study, it seems that chlorella supplement along with functional exercise can reduce the inflammatory and oxidative effects in obese people and increase the antioxidant effects.

The purpose of this study was to determine the effect of high-intensity circuit training with colostrum supplementation on the body composition and health factors of overweight men.

Methods and Materials: 

40 healthy overweight men were randomly divided into four groups of exercise and colostrum supplement, exercise and placebo, colostrum supplement and control. The training protocol consisted of three sessions per week for eight weeks. Subjects in the supplement and exercise-supplement group took 20 grams of powdered colostrum mixed with 200 ml of water every other day; then, they consumed them. The variables of fat percentage, blood fat, BMI index and waist to hip ratio were measured in all the subjects before and after supplementation and exercise.

The results showed that the percentage of body fat in the supplemental training group was significantly reduced compared to the colostrum supplement and exercise-placebo and control groups. Furthermore, blood fat, BMI and waist-to-hip ratio index showed a significant decrease in the exercisesupplement group compared to the other three groups.

In general, the interaction of high-intensity circuit training and colostrum supplementation causes a significant reduction in body fat percentage, blood fat, BMI, and waist-to-hip ratio. However, the need for more studies seems necessary considering the limitations of the research.

The purpose of this study was to determine the effect of high-intensity circuit training with colostrum supplementation on the body composition and health factors of overweight men.

40 healthy overweight middle-aged men were randomly divided into four groups: exercise and colostrum supplement, exercise and placebo, colostrum supplement and control. The training protocol consisted of three sessions per week for eight weeks. Subjects in the supplement and exercise-supplement group took 20 grams of powdered colostrum mixed with 200 ml of water every other day and then consumed it. Before and after supplementation and exercise, the variables of fat percentage, blood lipid, BMI index and waist to hip ratio were measured.

The results showed that the percentage of body fat in the supplement plus training group was significantly reduced compared to the colostrum supplement and exercise-placebo and control groups. Also, blood lipid, BMI and waist-to-hip ratio index showed a significant decrease in the exercise-supplement group compared to the other three groups.

In general, the interaction of high-intensity circuit training and colostrum supplementation causes a significant reduction in body fat percentage, blood fat, BMI, and waist-to-hip ratio.

The purpose of the present study is to investigate the effectiveness of narrative therapy on weight self-stigma among obese and overweight women.Research

The research method used in this study was a semi-experimental design, incorporating a pre-test, post-test, and follow-up assessment, with a control group. The current research population consisted of obese and overweight women in Tabriz city in 1402 who were referred to weight loss clinics. 30 women were selected by available sampling method and were then randomly divided into two groups: the experimental group and the control group. The experimental group received narrative treatment in 8 sessions of 90 minutes, while the control group did not receive any treatment and was placed on the waiting list. At the end of the treatment period, a post-test was performed in both groups. The tools used included the weight self-stigma questionary of Lillis et al. (2010). The collected data were analyzed using descriptive statistics and inferential statistics with the assistance of SPSS version 24 software.

In the pre-test, the mean and standard deviation of weight self-stigma variables in the experimental group was 41.27±4.217, while in the control group, weight self-stigma was 40.47±5.693. In the post-test stage, the values for weight self-stigma in the experimental group were 33.60 ± 4.137, while in the control group it was 40.33 ± 5.802. The results indicated the effectiveness of narrative therapy (P < 0.001). In the follow-up stages, it was found that the effects of narrative therapy are lasting.

The results showed that narrative therapy is effective in reducing weight self-stigma in obese and overweight women.

Given the high prevalence of obesity and overweight and the detrimental impact on the mental health of affected people, the objective of this study is to examine the effectiveness of narrative therapy on social physique anxiety in obese and overweight women.

The current research was a semi-experimental type, with a pre-test, post-test design with a control group. The study population for this research consisted of all obese and overweight women in Tabriz city in 2023. 30 women were selected by the available sampling method and were randomly divided into two groups: the experimental group and the control group. The experimental group received narrative treatment in 8 sessions of 90 minutes, while the control group did not receive any treatment and was placed on the waiting list. At the end of the treatment period, a post-test was performed in both groups. The Social Physique Anxiety Scale by Hart et al. (1989) was used as the measurement tool. The collected data were analyzed using descriptive statistics (mean and standard deviation) and inferential statistics (covariance test with repeated measures) by SPSS-24 software.

In the pre-test, the mean and standard deviation of social physique anxiety in the experimental group were 44.33±2.289, while in the control group, it was 43.67±3.063. In the post-test stage, the values for social physique anxiety in the experimental group were 36.33±3.117, while in the control group, it was 43.80±3.385. The results indicated the effectiveness of narrative therapy (p<0.001). In the follow-up stages, it was found that the effects of narrative therapy are lasting (p<0.001).

According to the results, it can be concluded that narrative can be an effective method for reducing social physique anxiety in obese and overweight women.

Marital satisfaction in couples depends on sexual satisfaction and better understanding of each other's needs. Physical changes such as overweight and obesity can negatively affect people's perception of their body and appearance and endanger their marital satisfaction. Therefore, the present study was conducted with the aim of determining the effectiveness of schema therapy on marital satisfaction and sexual schemas in overweight women.

The current research method is semi-experimental and a pre-post-test design with two experimental and control groups was used to collect data. The statistical population of the study was made up of all women suffering from weight gain in Tehran city living in region 1 in 2023. 30 people were selected by convenience and voluntary sampling and then, randomly divided into two experimental (15 people) and control groups. (15 people) were appointed. The experimental group received schema therapy intervention during 12 sessions of 90 minutes. The measurements used in this research included marital satisfaction (Fowers & Olson, 1993), sexual schema (Andersen and Cyranowski, 1994). The data was analyzed through spss-v24 software with ANCOVA method.

The findings showed that schema therapy intervention significantly improved marital satisfaction and sexual schemas (P<0.05).

A deeper understanding of childhood schemas, as discussed in the schema therapy intervention, can help to understand the dysfunctional personality traits that interfere with the treatment of overweight individuals. Also, by knowing the schemas, clients can achieve adaptive and compatible coping methods in married life.

Misperception of body weight and lack of awareness about overweight and obesity are associated with poor weight management behaviors. This cross-sectional study included 350 female students from Shahed University, Tehran, Iran, using a convenience sampling method. Data were collected through anthropometric measurements and self-reported answers regarding weight perception and level of body weight preoccupation. Data analysis was conducted using Spearman’s rank correlation coefficient. The findings revealed that 51.43% of the subjects misperceived their body weight. Among them, the majority (92.22%) underestimated their weight. Additionally, 17.14% of the overweight and obese subjects perceived their weight to be within the normal range, while 29.6% of obese subjects perceived themselves to be only slightly overweight. Furthermore, there was a significant relationship between body weight perception and anthropometric indices (p<0.01). The body mass index (r=0.739), C-index (r=0.648), body adiposity index (r=0.620), abdominal volume index (r=0.552), and waist-to-height ratio (r=0.537), and waist circumference (r=0.533) had the highest correlation with body weight perception, respectively. The high rate of unawareness of actual body weight among female university students is alarming. It is, therefore, necessary to develop programs that increase awareness about normal body weight and the importance of anthropometric indices in weight management.

Differences in foot structure are thought to be associated with differences in foot function during movement. The aim of this study was to investigate the effect of foot structure on plantar pressure characteristics in overweight girl children aged 10-13 years during walking.

Thirty-six overweight girls with pes planus, pes cavus and normal feet structures participated in this study. The plantar pressure characteristics of the subjects were measured using the foot-scan system while walking on a 14-meter gait-way at a self-selected speed. Peak plantar pressure, time to reach the peak pressure, percentage of the plantar contact area and impulse were measured. MANOVA and Bonferroni post hoc test were used for statistical analyses at a significance level of 0.05.

The mean peak pressure of the left foot of the pes cavus group under the hallux (12.47) was greater than that of the normal (7.93) and pes planus (7.49) groups (p=0.035). The mean impulse underneath the 2-5 toes zone of the right foot of normal (0.86) group was greater than pes planus (0.49) group (p=0.008). The mean impulse also was greater under the hallux zone of the left foot among pes cavus group (2.61) than those in normal (0.89) and pes planus (0.88) groups (0.045).

Despite the existence of minor differences; in general, the results of this study did not show a significant alteration in plantar pressure characteristics among overweight children with different foot structures during walking.

Pro-inflammatory cytokines such as leptin play an important role in the pathogenesis of obesity and metabolic syndrome. Exercise and food supplements are two suitable approaches to prevent the phenomenon of overweight and obesity. This study aimed to investigate the effect of eight weeks of total body resistance training (TRX) and omega-3 supplementation on serum leptin levels and body fat percentage in overweight and obese women.

In this semi-experimental research, 48 overweight and obese women were purposefully selected as a statistical sample and randomly divided into four groups of 12 people: 1) training, 2) supplement, 3) training +supplement, and 4) control. The subjects of the first and third groups performed the exercise training protocol (TRX) for eight weeks (Three sessions per week). Also, the subjects of the second and third groups received two 1000 mg capsules of omega-3 supplement daily, and the first and fourth groups received the same amount of placebo (Oral paraffin). At the beginning and end of the study, measuring body fat percentage using a body composition measuring device and venous blood samples were collected to measure biochemical values. Data were analyzed using one-way analysis of variance, and Tukey's post hoc test at a significance level of less than 0.05.
