Modernisation has brought increased comforts and limited mobility in our lives at the cost of an increased prevalence of hypertension, diabetes mellitus, dyslipidaemia, and obesity, which are predecessors of major cardiovascular diseases. Prevention and control of coronary heart disease and its associated diseases are essential and can be achieved by modifying the lipid profile. The aim of this study was to systematically assess the effects of yoga on blood lipid levels. This study is a systematic review and meta-analysis of fifty-three randomised controlled studies. All studies employed a parallel design with a total of 13,191 participants whom were divided into 6,700 individuals in the control group and 6,517 in the intervention group. Results show that yoga had decreased total cholesterol, low-density lipoprotein cholesterol, triglycerides, and very low-density lipoprotein cholesterol and increased high-density lipoprotein cholesterol among yoga practitioners. Authors conclude that yoga had a striking effect on balancing lipid profiles.
Abstract
OBJECTIVES Yoga is a mind-body stress-relieving exercise that increases mental and physical health, which may have a role in the improvement of metabolic disorders. The present study has reviewed the effect of yoga on lipid profiles as a systematic review and meta-analysis. METHODS We evaluated the available randomized controlled trials on the effects of yoga-based programs, and lipid profiles by searching PubMed/Medline, Scopus, Web of Science, and the Cochrane central register of control trials up to January 2022. Both fixed and random effect analyses were used to find the relationships. Subgroup analysis was performed based on the continent, duration of the included studies, gender, and health condition of participants to discover the sources of heterogeneity. RESULT Fifty-three studies were included in the current systematic review and meta-analysis with a total sample size of 13,191. There was a striking association between yoga and total cholesterol (-10.31 mg/dl; 95% CI: -14.16, -6.45; I 2 = 82.5%, P < 0.001), low-density lipoprotein cholesterol (-8.64 mg/dl; 95% CI: -12.03, -5.25; I 2 = 75.0%, P < 0.001), high-density lipoprotein cholesterol (1.98 mg/dl; 95% CI: 0.81, 3.14; I 2 = 91.6%, P < 0.001), triglycerides (-13.50 mg/dl; 95% CI: -20.09, -6.92; I 2 = 90.7%, P < 0.001) and very low-density lipoprotein (-3.94 mg/dl; 95%CI: -6.31, -1.56; I 2 = 72.2%, P < 0.001). CONCLUSION It seems yoga interventions had a substantial effect on lipid profiles, however, more qualified trials or cohort studies are needed to conclude exactly.

Plain language summary
Metabolic syndrome (MetS) is a cluster of co-occurring pathological conditions, characterised by insulin resistance, abdominal obesity, hypertension and dyslipidaemia One possible factor contributing to MetS risk is change in microbiome composition. Diets high in processed foods appear to alter microbiome composition in ways that promote higher fat mass and insulin resistance. Additionally, a sedentary lifestyle decreases microbiome diversity, elevating inflammation and metabolic disease risk. Research on how the microbiome responds to modest, attainable changes in diet and physical activity will help identify which dietary adjustments and exercise types have the greatest potential to protect patients from MetS.
Abstract
Metabolic syndrome (MetS) is a cluster of harmful conditions which occur together, such as insulin resistance, abdominal obesity, and hypertension. The global prevalence of MetS is growing rapidly, with some estimates suggesting over one billion people worldwide experience increased morality and disease rates linked with this syndrome. One possible factor contributing to MetS risk is changes in microbiome composition. Approximately 100 trillion bacteria and other microbes reside in the human intestinal tract, collectively termed the gut microbiome. Humans and microbes share a long evolutionary history, with many of these microbes influencing human health outcomes. However, environmental conditions have changed dramatically with human technological innovations; many of these changes (e.g., diets high in processed foods and sedentary lifestyles) appear to impact human-microbe relationships. In general, recent changes in diet and activity patterns have been linked to decreased microbiome diversity, elevating inflammation and metabolic disease risk and likely promoting the development of MetS. Targeting patient diet or exercise patterns may therefore help doctors better treat patients suffering from MetS. Still, additional work is needed to determine how the microbiome responds to changes in patient activity and diet patterns across culturally and biologically diverse human populations.

Plain language summary
Menopause is the absence of menstruation due to the loss of ovarian activity with ageing. During this transition period, changes in hormones, primarily the decline in the oestrogen estradiol, give rise to altered lipid metabolism. An unfavourable lipid profile presents a risk for metabolic disorders, such as cardiovascular diseases and type 2 diabetes. Post-menopausal changes also lead to shifts in body fat and fat distribution, resulting in an increased tendency for central fat accumulation and obesity. Obesity is associated with insulin resistance. This susceptibility for weight accumulation is possibly also driven by the age-associated decline in skeletal muscle, which reduces metabolic energy expenditure. This review summarizes the physiology of menopause and postmenopause and the consequential impact on lipid metabolism. In addition, there is a discussion of dietary recommendations, nutritional and plant-derived compounds that could support the management of menopause associated changes in lipid levels, metabolic risk factors and obesity. The recommendations discussed include traditional healthy diets and low-calorie diets, with attention drawn to adequate protein intake. Furthermore, the role of probiotics, nutritional and plant-sourced constituents are considered, including Vitamin D, Omega-3 fatty acids, antioxidants like Vitamin A, β-carotene, Vitamin C and E, genistein, resveratrol, flavonoids, indoles and capsaicin. The authors advocate sourcing these compounds from a varied whole-foods diet, which would minimize nutrient interactions and absorption issues that can occur with supplementation. This review may be of interest to those supporting the nutritional needs of menopausal and post-menopausal women, that are experiencing or are at risk of experiencing metabolic disorders.
Abstract
Menopause is clinically diagnosed as a condition when a woman has not menstruated for one year. During the menopausal transition period, there is an emergence of various lipid metabolic disorders due to hormonal changes, such as decreased levels of estrogens and increased levels of circulating androgens; these may lead to the development of metabolic syndromes including cardiovascular diseases and type 2 diabetes. Dysregulation of lipid metabolism affects the body fat mass, fat-free mass, fatty acid metabolism, and various aspects of energy metabolism, such as basal metabolic ratio, adiposity, and obesity. Moreover, menopause is also associated with alterations in the levels of various lipids circulating in the blood, such as lipoproteins, apolipoproteins, low-density lipoproteins (LDLs), high-density lipoproteins (HDL) and triacylglycerol (TG). Alterations in lipid metabolism and excessive adipose tissue play a key role in the synthesis of excess fatty acids, adipocytokines, proinflammatory cytokines, and reactive oxygen species, which cause lipid peroxidation and result in the development of insulin resistance, abdominal adiposity, and dyslipidemia. This review discusses dietary recommendations and beneficial compounds, such as vitamin D, omega-3 fatty acids, antioxidants, phytochemicals-and their food sources-to aid the management of abnormal lipid metabolism in postmenopausal women.

Plain language summary
Metabolic Syndrome is the term used to group a cluster of health concerns including overweight, obesity, hypertension, elevated cholesterol, blood glucose intolerance and insulin resistance which together can contribute to the development of Type II Diabetes and Cardiovascular Disease. Diagnosis is usually given if a patient has three or more of these conditions however the diagnosis in children and adolescents is often inconsistent, and so guidelines for therapeutic strategies for metabolic syndrome also vary greatly. This review looked at 9 studies of children aged up to 19 years old, all diagnosed with metabolic syndrome, and given dietary, physical, psychological, and pharmacological interventions, to try and understand what the best clinical approach might be. It was found that a balanced diet combined with aerobic and resistance exercise helped to significantly reduce body mass, more so than the trials which included treatment with Metformin. A balance diet included calorie restriction and carbohydrate reduction, carefully planned around the daily exercise program of 2-3 resistance sessions each week and frequent cardio sessions of differing intensity and duration. They concluded that a minimum of 6 months was needed to reach optimal weight loss and body fat loss. Overall, the findings of this study support diet and physical exercise as beneficial clinical interventions, whilst the use of medication is still unclear.
Abstract
OBJECTIVE To record which interventions produce the greatest variations in body composition in patients ≤19 years old with metabolic syndrome (MS). METHOD search dates between 2005 and 2017 in peer reviewed journals, following the PRISMA method (Preferred Reporting Items for Systematic reviews and Meta-Analyses). The selection criteria were: diagnostic for MS or at least a criterion for diagnosis; randomized clinical trials, ≤19 years of age; intervention programs that use diet and/or exercise as a tool (interventions showing an interest in body composition). RESULTS 1781 clinical trials were identified under these criteria but only 0.51% were included. The most frequent characteristics of the selected clinical trials were that they used multidisciplinary interventions and were carried out in America. The most utilized parameters were BMI (body mass index) in kg/m² and BW (body weight) in kg. CONCLUSIONS Most of the clinical trials included had been diagnosed through at least 2 diagnostic criteria for MS. Multidisciplinary interventions obtained greater changes in body composition in patients with MS. This change was especially prevalent in the combinations of dietary interventions and physical exercise. It is proposed to follow the guidelines proposed for patients who are overweight, obese, or have diabetes type 2, and extrapolate these strategies as recommendations for future clinical trials designed for patients with MS.

Plain language summary
Medicinal mushrooms have long been considered healthful due to of their anti-oxidant and anti-inflammatory properties, such as high-quality proteins, polyunsaturated fatty acids, polyphenols etc. More recently they have been analysed for their anti-obesity effects. The health implications of obesity are extensive, often affecting all bodily systems. The purpose of this review was to analyse previous animal studies to determine whether consuming edible mushrooms has a positive effect on obesity related illnesses, such as Type 2 diabetes and cardiovascular disease etc. The authors explore and summarise the different methods used to treat obesity including pharmacotherapy (weight loss drugs), natural products such as Ayurveda medicine and exercise. They present promising results that suggest the therapeutic properties of edible mushrooms have anti-obesity potentials and propose that the findings from animal studies could likely be mirrored in humans and recommend consuming mushrooms to aid weight loss and therefore improve health.
Abstract
Obesity is a group of metabolic disorders caused by multiple factors, including heredity, diet, lifestyle, societal determinants, environment, and infectious agents, which can all lead to the enhancement of storage body fat. Excess visceral fat mass in adipose tissue generate several metabolic disorders, including cardiovascular diseases with chronic inflammation based pathophysiology. The objective of the current review is to summarize the cellular mechanisms of obesity that attenuate by antioxidant potentials of medicinal and edible mushrooms. Studies have showed that mushrooms potentially have antioxidant capacities, which increase the antioxidant defense systems in cells. They boost anti-inflammatory actions and thereby protect against obesity-related hypertension and dyslipidemia. The practice of regular consumption of mushrooms is effective in the treatment of metabolic syndrome, including obesity, and thus could be a good candidate for use in future pharmaceutical or nutraceutical applications.
