Effects of a vegetarian diet combined with aerobic exercise on glycemic control, insulin resistance, and body composition: a systematic review and meta-analysis

BACKGROUND

Vegetarian diets and aerobic exercise are increasingly accepted as a common way to improve lifestyle. Several studies have shown that vegetarian diets combined with aerobic exercise interventions have a significant effect on preventing and reducing the risk of metabolic diseases.

METHODS

A search of the PubMed, EBSCO, Embase, CENTRAL, and Web of Science databases was conducted for comparative studies of pre- and post-vegetarian diet adoption combined with aerobic exercise interventions on glycemic control and body composition. Qualitative reviews and meta-analyses of fixed and random effects were conducted to pool available data. The results were validated by sensitivity analysis.

RESULTS

A total of 27 studies were selected for meta-analysis. Combining the studies included in the meta-analysis showed a mean difference for homeostasis model assessment of insulin resistance of - 0.75 (- 1.08 to - 0.42), fasting plasma glucose of - 0.27(- 0.30 to - 0.23), waist circumference of - 1.10 (- 5.06 to 2.86) and body mass index of - 0.70 (- 1.38 to - 0.01).

CONCLUSION

In summary, our findings suggest that participants who adopted a vegetarian diet combined with aerobic exercise intervention had significantly lower fasting plasma glucose and insulin levels and improved body composition compared to preintervention participants.

Influence of Comprehensive Lifestyle Intervention (LSI) Program on Health, Fatigue, and Quality of Life in Middle-Aged Women

Background

Middle age is one of the most important times in a woman's life, and it is a time when multiple changes occur that affect the body and health. The study aimed to investigate the efficacy of a comprehensive lifestyle intervention (LSI) program, including stress management, on middle-aged women's physical, physiological, and mental health.

Methods

A total of 40 middle-aged women participated in a short-term LSI program, nutrition, exercise, and mental and physical management with various experiential activities. Physical measurements, biochemical indicators, stress hormones, chronic fatigue, and quality of life indicators were evaluated to interpret the clinical efficacy of the program.

Results

LSI program significantly improved satisfaction and quality of life in participants. Total chronic fatigue scores reduced significantly compared to scores before the start of the program. Moreover, fat mass and body fat were reduced without loss of muscle mass. Further, blood pressure and triglyceride levels significantly decreased after completing the LSI program. However, changes in stress hormone levels remained insignificant.

Conclusion

Adoption of LSI in middle-aged women demonstrated positive implications of the program. LSI efficiently regulates body fat, fat mass, fatigue, hypertension, and triglyceride levels which play a critical role in determining the quality of life. Thus, the LSI program could spread healthy lifestyles among middle-aged women.

Effects of a vegetarian diet combined with exercise on lipid profiles and blood pressure: A systematic review and meta-analysis

We aimed to evaluate the combined effects of a vegetarian diet (VD) and exercise on total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), systolic blood pressure (SBP), and diastolic blood pressure (DBP) parameters. A literature search was conducted in electronic databases from build to February 27, 2022. Data were synthesized using random effects model and were expressed as standardized mean difference (SMD)/weighted mean difference (WMD) and 95% confidence interval (CI). Overall, 27 trials with 9,251 participants were included. Pooled results indicated that the combination of a VD and exercise significantly reduced TC (SMD: -0.524; 95% CI: -0.602, -0.446; p < 0.001), LDL-C (SMD: -0.379; 95% CI: -0.471, -0.287; p < 0.001), HDL-C (SMD: -0.213; 95% CI: -0.299, -0.126; p < 0.001), TG (SMD: -0.090; 95% CI: -0.160, -0.020; p = 0.012), SBP (WMD: -7.664 mm Hg; 95% CI: -9.219, -6.109 mm Hg; p < 0.001), and DBP (WMD: -4.347 mm Hg; 95% CI: -5.099, -3.596 mm Hg; p < 0.001). These parameters were reduced more following a low-fat VD, or a mixed high-frequency exercise, especially under strict supervision. Surprisingly, the decreased HDL-C due to VD was observed to recover with the prolongation of exercise.
