Non-alcoholic fatty liver disease (NAFLD) has emerged as the predominant cause of chronic liver disease. Given the association between NAFLD and metabolic syndrome [11,12], lifestyle modification can improve patients’ life quality and prognosis. The aim of this study was to assess the joint association of several modifiable lifestyle factors with overall and cause-specific mortality among NAFLD individuals and depict the mortality risk of varied composite modes of lifestyle. This study is a large, nationally representative, population-based study. It is based on the NHANES III (1988–1994, the National Center for Health Statistics, the Center for Disease Control and Prevention), which used a complex multistage probability design to recruit a representative sample of participants. Results show a protective effect among NAFLD participants following a healthy lifestyle, particularly impacting CVD-related mortality. Notably, among the most common lifestyle factor combinations, the effect of risk reduction on mortality was particularly strong when smoking was avoided. Authors conclude that their findings can be a useful tool to help the general public and patients with NAFLD to understand the importance of maintaining a healthy lifestyle.
Abstract
BACKGROUND AND AIMS It is unclear whether a healthy lifestyle impacts mortality in the presence of non-alcoholic fatty liver disease (NAFLD). The present study aimed to examine the joint association of several modifiable lifestyle factors with mortality risk for NAFLD patients. METHODS We collected lifestyle behavior data form the National Health and Nutrition Examination Survey (NHANES) III from 1988 to 1994 and follow-up data form NHANES III-linked mortality data through 2015. We estimated joint association between four healthy lifestyle factors (non-smoking, non-drinking, regular physical activity, a healthy diet) after NAFLD diagnosis and mortality using Cox proportional hazards regression models. RESULTS During a median of 22.83 years of follow-up, 2932 deaths occurred. The risk of all-cause mortality decreased significantly with the healthy lifestyle scores increasing (p < 0.001). NAFLD patients with a favorable lifestyle (3 or 4 healthy lifestyle factors) reduced 36% of all-cause mortality and 43% of cardiovascular disease (CVD) mortality compared with those with an unfavorable lifestyle (0 or 1 healthy lifestyle factor) (HR, 0.64 [95% CI, 0.50-0.81], 0.57 [95% CI, 0.37-0.88]). Compared with the non-NAFLD group, the number of NAFLD patients required to adhere to a favorable lifestyle to prevent one cardiovascular disease death in 20 years was fewer (77 vs. 125). CONCLUSIONS For the NAFLD patients, adopting a healthy lifestyle could significantly reduce their risk of death.

With obesity on the rise this analysis of 22 trials and a total of 870 overweight or obese adults looks at whether soy products are effective food for weight loss. Sixteen trials examined soy products and Body Mass Index (BMI) and concluded that soy products significantly reduced body mass compared to the control groups. The remaining studies examined the effects of soy on fat mass, fat percentage, and waist and hip circumference and showed declines in fat mass but not significant reductions in waist and hip measurements. The amalgamated results showed a total reduction of 0.34 kg body weight. Various types of soy products were included such as soy protein, isoflavones, soy milk, soy shakes and some other soy products. Further sub-group analysis showed differences in people from developed countries (typically a BMI higher than 25.0) versus developing countries (average BMI lower than 25.0). They also highlighted differences between cultures with meat-based and plant-based diets and the wide acceptance of soy in Asia. Significant effects were observed in non-menopausal women with reduced body weight, BMI and waist circumference, while no results were observed in postmenopausal women. The study concludes that soy protein, isoflavones and fibre all contribute to fullness and signalling pathways which may be helpful in reducing body weight.
Abstract
BACKGROUND The effect of soy products on the weight of overweight or obese people is controversial, so we aimed to conduct a systematic review and a meta-analysis of published randomized controlled trials to analyze whether supplementation with soy products can help them to lose weight. METHODS The relevant data before January 2019 in PubMed, Embase and Cochrane Library were searched. A random-effect model was adopted to calculate the weighted average difference of net changes of body weight, body mass index (BMI), body fat percentage, fat mass, waist circumference, etc. Results: A total of 22 trials (870 overweight or obese participants) were reflected in the present meta-analysis. Analysis showed that soy products significantly reduced body weight, BMI, body fat percent and waist circumference in overweight or obese Asian populations (-0.37 kg, P = 0.010; -0.27 kg/m2, P = 0.042; -0.36%, P = 0.032; -0.35 cm, P = 0.049) and more significant effects were observed in non-menopausal women reduced body weight (-0.59 kg, P = 0.041), BMI (-0.59, P = 0.041) and waist circumference (-0.59 cm, P = 0.041) in overweight or obese populations. CONCLUSION This meta-analysis showed that soy products have weight loss effects, mainly due to soy protein, isoflavone and soy fiber.
