Abstract
Background: Animal studies have shown maternal low/ high-calorie diet during pregnancy can alter metabolism of offspring through change in Sirtuin 1 (SIRT1) expression, as a metabolic sensor. However, there is no study on the effects of isocalorie diet. Herein, effects of two isocalorie diets with different amounts of fat were assessed on SIRT1 gene and protein level in the liver of male and female offspring.
Methods: The control group received AIN93G diet. In this diet, 16% and 64% of total calorie were prepared from fat and carbohydrate, respectively. The intervention group received high fat AIN93G diet contained 48% and 32% of calorie from fat and carbohydrate, respectively. In both diets, fat was prepared from soy oil. Diets were isocaloric and 20% of total calorie was provided from protein. Mothers categorized to one of these diets and offspring received the control diet after weaning (3 weeks after the birth).
Results: SIRT1 gene and protein levels were lower in male and female offspring born from mothers received high-fat diet than the controls (p<0.001).
Conclusion: Change in maternal dietary fat, without increase in calorie, effects on gene and protein levels of SIRT-1 in the liver of next generation.

Abstract
Background: Leptin and adiponectin are adipokines produced by fat cells and play an important role in obesity. The purpose of this study was to compare the effect of low-calorie diet (LCD) and exercise (Exe) on leptin and adiponectin in middle-aged and elderly adults with overweight and obesity.
Methods: A systematic search was conducted in PubMed, Web of Science, SID, Magiran, and Google scholar databases for English and Persian articles published until August 2023. The effect size and 95% confidence interval (CI) were calculated using the random effect model.
Results: The results of 25 studies with 2063 middle-aged and elderly people with overweight and obesity showed that the combination of exercise and diet compared to exercise alone causes a significant decrease in serum leptin [SMD=-0.4, P=0.001], and a significant increase in serum adiponectin [SMD=0.17, P=0.02] in middle-aged and elderly adults with overweight and obesity. Also, findings showed that the diet compared to exercise alone causes a decrease in serum leptin [SMD=-0.16, P=0.1], and a significant increase in serum adiponectin [SMD=0.05, P=0.7] in middle-aged and elderly adults with overweight and obesity. Also, diet compared to exercise alone does not cause a significant change in serum leptin [SMD=-0.11, P=0.2], and serum adiponectin [SMD=0.02, P=0.8] in middle-aged and elderly adults with overweight and obesity. Conclusion: It is suggested that middle-aged and elderly people to achieve hypoleptinemia and hyperadiponectinemia, use a combination Include exercise training and low-calorie diet in your lifestyle.
