Abstract
Background & Objectives: Obesity is associated with metabolic abnormalities such as insulin resistance. Weight loss is always recommended for meaningful reduction in these abnormalities. Therefore, we examined the effects of balanced low calorie diet on weight loss, fasting insulin and insulin resistance in obese women attending the nutrition clinic.
Methods: In this clinical trial, forty five volunteer apparently healthy obese women (body mass index: 33.28 ± 2.90 kg/m2 and age: 28.40 ± 7.98 years) were recruited from the nutrition clinic in their first visit. The participants were received a balanced low calorie diet over 6 months after anthropometry measurement and blood sampling for determination of fasting insulin and insulin resistance level. Balanced low calorie diet was an individualized diet with an energy deficit of 500 calories of daily energy intake that was calculated from 3-day food records for every person. At 6 months after intervention, continuous and dichotomous variables were assessed using paired t-test and McNemar test, respectively.
Results: The mean recommended energy intake was 2241.78 ± 219.02(kcal). After 6 months, there were significant reductions in body weight (p=0.003), body mass index (p=0.005), waist and hip circumferences (p<0.001 and p<0.001, respectively). There was also significant improvement in fasting insulin level (13.47 ± 6.55 vs. 11.95 ± 4.17 µU/ml, p=0.01). Whereas, insulin resistance had not significant reduction (p=0.1).
Conclusion: In obese women attending the nutrition clinic, the balanced low calorie diet resulted in weight loss and improvement in fasting insulin. These positive changes can help to decrease the risk factor profile in obese individuals.

Abstract
Background & objective: Aloe-vera is an herb that has long been used in traditional medicine. Using high-fat diet and fatty liver disorder cause obesity and hyperlipidemia. So, this study aimed to investigate the effects of Aloe - vera gel extract on the body weight and lipid profile in adult male rats treated with high-fat diet.
Methods: In this experimental study, 40 adult male rats were included in the control group (no treatment), sham group (treated with high-fat diet 10 ml/kg) and three experimental groups receiving high-fat diet (10ml/kg) along with 150, 300 and 600 mg/kg Aloe- vera gel extracts. Prescriptions were conducted by gavage, for 60 days. At the end, after anesthetizing the rats and phlebotomizing their heart, the serum levels of cholesterol, triglycerides, LDL and HDL were measured. The obtained results were analyzed by ANOVA and Duncan tests.
Results: The results showed that high-fat diet significantly increased the serum levels of cholesterol, triglycerides, LDL (p<0.001) and weight gain (p<0.01) but had no significant effect on the serum level of HDL. However, in the groups receiving Aloe -vera gel and high-fat diet, there was a significant decrease in the weight and serum levels of cholesterol, triglyceride (p<0.05) and LDL (p<0.01).
Conclusion: High-fat diets increase the weight and serums levels of triglycerides, LDL and cholesterol. Also, the Aloe- vera gel extract causes weight loss and improves lipid profiles in the rats treated with Aloe -vera gel extract.

Abstract
Background & objectives: The aim of the present study was to evaluate 8 weeks individualized balanced low calorie diet on anthropometric measurements in apparently healthy obese women.
Methods: Forty apparently healthy obese women (age: 18-40 years and 27.5≤BMI≤40 kg/m2) were recruited from the nutrition clinic in Ardabil city. The participants received a balanced low calorie diet after anthropometric measurements. Paired T-test was used to compare the changes during 8 - week intervention.
Results: Individualized balanced low calorie diet resulted in a significant decrease in body weight (-3.99±0.34 kg, p<0.001), body mass index (-1.61±0.14 kg/m2, p<0.001), waist circumference (-2.91±0.32 cm, p<0.001), hip circumference (-1.89±0.37 cm, p<0.001), waist to hip ratio (-0.01±0.004, p=0.001), waist to stature ratio (-0.02±0.002, p<0.001), body adiposity index (-0.97±0.15%, p<0.001), abdominal volume index (-1.07±0.11, p<0.001) and conicity index (-0.007±0.002, p=0.001) during 8 weeks.
Conclusion: Based on the results, an individualized balanced low calorie diet induced weight loss and decreased other anthropometric measurements during 8 weeks. Balanced low calorie diet-induced moderate weight loss alone can be a good way to reduce metabolic risk factors in obese women. .

Abstract
Background: Weight gain and obesity are the global health problem. Time-restricted feeding is a relatively new method of weight loss with many metabolic and anthropometric benefits. Low-intensity aerobic exercise also has beneficial effects on weight loss and metabolic factors; However, the combined effect of TRF and low-intensity aerobic exercise on metabolic and anthropometric factors in healthy overweight middle-aged men has rarely been investigated. The present research has investigated this purpose.
Methods: Among 55 volunteers, 27 healthy middle-aged men in the age (35 to 55) with overweight (25 The groups included: 1-TRF18:6 & EX 2-TRF 16:8 & EX 2-TRF 14:10 & EX. Three groups performed TRF protocols with different feeding times (6, 8 and 10 hours of free feeding) and fasting in the remaining 24 hours, and the same low -intensity aerobic exercise (55-65% of maximum heart rate). The interventions continued for 12 weeks. Blood and body composition tests were measured before and after the intervention. Daily food intake was measured before the intervention and during 12 weeks. Finally, all the data were analyzed.Analysis of variance with repeated measures was used for analysis. P values less than 0.05 were considered as a significant criterion in all statistical tests.
Results: The combination of TRF and exercise decreased glucose and insulin resistance in all groups. Cholesterol and LDL decreased in the 6-h and 8-h TRF groups. HDL reduction was significant only in the 8-h TRF group. Weight and BMI were reduced in the 6-h and 8-h TRF groups. The percentage of fat reduced in the 6-h group. There was no significant difference between the groups for any of the variables. The average energy received in 12 weeks was not significantly different in any group; however the 6-h model caused a greater decrease in the average energy received during 12 weeks than in the other two groups.
Conclusion: The 6-h TRF model along with light aerobic exercise is suggested as the most reliable method to improve the metabolic and anthropometric profile in overweight middle-aged men.
