Aging and obesity share pathophysiological mechanisms, such as chronic inflammation and oxidative stress. However, distinct obesity phenotypes exist, such as metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO). Consequently, therapeutic interventions involving nutritional strategies and physical training are highly relevant, especially for older women. Taurine, a sulfur-containing amino acid, plays a role in modulating oxidative stress, inflammation, osmoregulation, and mitochondrial function. Rationale: Plasma taurine concentrations are lower in women with obesity compared to healthy individuals. However, studies investigating these concentrations across different phenotypes-particularly in older women, a group susceptible to functional and metabolic changes-remain limited. Understanding these variations could clarify taurine's role in the pathophysiology of obesity and aging and inform personalized therapeutic strategies. Combined physical training stands out as an effective strategy for modulating inflammatory, oxidative, and metabolic pathways, in addition to improving psychosocial aspects. Given that taurine levels can be influenced by these pathways, investigating the taurine response to physical training across different metabolic phenotypes may contribute to developing low-cost interventions aimed at improving the quality of life for older women with obesity.",[29,30,31],"Obesity (BMI>30)","Metabolically Healthy Obesity","Metabolically Unhealty Obese",[33,34,35,36,37],"Taurine","Metabolically unhealthy obesity.","Metabolically healthy obesity.","Physical training","Aging","NOT_YET_RECRUITING","2026-07-16",{"date":41,"type":42},"2026-07-20","ACTUAL",{"date":44,"type":23},"2026-10-01",{"date":46,"type":23},"2030-03-01",{"name":48,"class":49},"University of Sao Paulo","OTHER",{"id":51,"slug":52,"hasResults":11,"nctId":53,"briefTitle":54,"officialTitle":55,"acronym":56,"eligibilityCriteria":57,"healthyVolunteers":17,"sex":58,"minAge":59,"maxAge":60,"enrollmentInfo":61,"targetDuration":4,"studyType":24,"phases":63,"briefSummary":64,"conditions":65,"keywords":69,"overallStatus":73,"whyStopped":4,"lastUpdateSubmitDate":74,"lastUpdatePostDateStruct":75,"startDateStruct":77,"completionDateStruct":79,"leadSponsor":81,"locationsCount":83},"100510997","small-extracellular-vesicles-and-insulin-action-100510997","NCT05933707","Small Extracellular Vesicles and Insulin Action","Effect of Small Extracellular Vesicles From Adipose Tissue on Insulin Action","SEV","Inclusion Criteria:\n\n* Metabolically healthy lean subjects must have a BMI ≥18.5 and ≤24.9 kg\u002Fm²; Subjects with obesity must have a BMI ≥30.0 and ≤50.0 kg\u002Fm²\n* Metabolically healthy lean and people with metabolically healthy obesity must have intrahepatic triglyceride (IHTG) content ≤5%; fasting plasma glucose concentration \\\u003C100 mg\u002Fdl, 2-hr oral glucose tolerance plasma glucose concentration \\\u003C140 mg\u002Fdl, hemoglobin A 1C (HbA1c) ≤5.6% and HOMA-IR \\\u003C2.5.\n* People with metabolically unhealthy obesity must have intrahepatic triglyceride (IHTG) content ≥5.6%; HOMA-IR ≥2.5, and HbA1c 5.7%-6.4%, or fasting plasma glucose concentration ≥100 mg\u002Fdl, or 2-hr oral glucose tolerance test (OGTT) plasma glucose concentration ≥140 mg\u002Fdl.\n\nExclusion Criteria:\n\n* History of diabetes, liver disease other than NAFLD or other serious diseases,\n* Consume excessive amounts of alcohol (\\>21 units\u002Fweek for men and \\>14 units\u002Fweek for women),\n* Take medications that could affect the study outcome measures, engage in regular exercise (\\>120 min\u002Fweek),\n* Are pregnant or lactating","ALL","25 Years","55 Years",{"count":62,"type":23},72,[26],"The goals of this research study are to: 1) understand why some people with obesity are protected from developing conditions such as type 2 diabetes and cardiovascular disease while others are more likely to develop obesity-related conditions; 2) assess the effect of small extracellular vesicles (sEVs also called exosomes), obtained from human participants, on metabolic function in cultured cells and in mice.",[66,67,30,68],"Obesity","Insulin Resistance","Obesity, Metabolically Benign",[66,70,71,72],"Weight Loss","Exosomes","Extracellular vesicles","RECRUITING","2026-07-15",{"date":76,"type":42},"2026-07-17",{"date":78,"type":42},"2023-06-14",{"date":80,"type":23},"2028-08-31",{"name":82,"class":49},"Washington University School of Medicine",1,{"id":85,"slug":86,"hasResults":11,"nctId":87,"briefTitle":88,"officialTitle":89,"acronym":4,"eligibilityCriteria":90,"healthyVolunteers":17,"sex":58,"minAge":91,"maxAge":60,"enrollmentInfo":92,"targetDuration":4,"studyType":24,"phases":94,"briefSummary":95,"conditions":96,"keywords":97,"overallStatus":73,"whyStopped":4,"lastUpdateSubmitDate":102,"lastUpdatePostDateStruct":103,"startDateStruct":105,"completionDateStruct":107,"leadSponsor":109,"locationsCount":83},"100635941","gut-immune-and-vascular-health-in-metabolically-healthy-obesity-100635941","NCT07559227","Gut, Immune, and Vascular Health in Metabolically Healthy Obesity","Impaired Gut-Vascular Axis as a Unique Driver of Cardiovascular Disease in Metabolically Healthy Obesity","Inclusion Criteria:\n\n* 18-55 years old.\n* BMI is 18.5-24.9 kg\u002Fm2 or \\>30kg\u002Fm2 (part 1).
