This corresponds to all the fat in the body (or adipose tissue). It is opposed to the lean mass which corresponds to the weight of muscles, organs and viscera. It is defined from the body mass index (or BMI). BMI is calculated by dividing a person\'s weight by their height squared.\n\nAccording to these criteria, the prevalence of obesity has reached 17% of the entire adult population in mainland France (ESTENBAN 2015 study). The prevalence figures for obesity in the French overseas departments are higher than in mainland France. The latest epidemiological data available in Martinique and Guadeloupe (KANNARI 2015 study) show that approximately 60% of the adult population is overweight and 25% of the adult population is obese.\n\nObesity is considered a chronic disease that increases the risk of cardiovascular and metabolic complications all the more when patients have a BMI ≥ 35 kg/m2, defining severe obesity. When BMI is equal to or exceeds 40 kg/m2, obesity is said to be "morbid" and the risk of cardiovascular complications increases by about 100% to 400% depending on the type of complications. The risk of mortality increases by 50 to 100% compared to the normal weight population.\n\nObesity and inflammation Adipose tissue accumulates around the abdominal viscera after the fat storage capacity of the subcutaneous territories has been reached. The accumulation of visceral fat is accompanied by a low-grade inflammatory response that is responsible for the secretion of lipid derivatives and mediators toxic to the cardiovascular system and insulin sensitivity. The inflammatory response is characterized by the expression of numerous pro-inflammatory molecules synthesized by adipocytes and immunocompetent single-macrophage cells infiltrating the vascular stroma of adipose tissue. In addition, hyperglycemia and excess lipid intermediates cause the assembly of inflammasomes in the cytosol. Among them, the NLRP3 inflammasome involved in multiple human inflammatory pathologies.\n\nInflammation opposes weight loss, hence the need to reduce the inflammatory response to facilitate weight loss in obese people.\n\nPigeon pea, known for its anti-inflammatory properties, is a legume found in Creole gardens and traditionally eaten at Christmas.\n\nThe OBESICA study aims at studying the interest of consuming pigeon pea associated with regular physical activity on the inflammatory state of the body and weight loss in obese patients.', 'detailedDescription': 'Obesity is a generic term for excess body fat. In adults, the World Health Organization (WHO) defines overweight and obesity by a body mass index (BMI) ≥ 25 kg/m2 and 30 kg/m2, respectively. According to these criteria, the prevalence of obesity has reached 17% of the entire adult population in France (ESTENBAN 2015 study). Obesity prevalence figures in the French overseas departments are higher than in France : 60% of the adult population in Martinique and Guadeloupe is overweight and 25% of the adult population is obese (KANNARI 2015 study).\n\nObesity increases the risk of cardiovascular and metabolic complications even more when patients have a BMI ≥ of 35 kg/m2, defining severe obesity. When the BMI is equal to or greater than 40 kg/m2, obesity is said to be "morbid" and the risk of cardiovascular complications increases by between 100% and 400% depending on the type of complications. The risk of mortality increases in the order of 50 to 100% compared to the normal weight population. However, some individuals do not present cardio-metabolic abnormalities despite a significant excess of fat.\n\nSeveral studies show that cardiovascular and metabolic complications are indeed linked to the accumulation of abdominal visceral fat.\n\nAn abdominal girth ≥ 94 cm in men and ≥ 80 cm in women defines abdominal obesity and predicts a high risk of cardiovascular complications. While in France, abdominal obesity affects about 40% of adults, it affects 47% of men and up to 70% of women in overseas territories.\n\nThe accumulation of visceral fat is accompanied by a low-grade inflammatory response that is responsible for the secretion of lipid derivatives and mediators that are toxic to the cardiovascular system and insulin sensitivity.\n\nThe inflammatory response is characterized by the expression of numerous pro-inflammatory molecules synthesized in particular by adipocytes. In addition to the activation of nuclear transcription factors such as NFκB and AP-1, metabolic danger signals such as hyperglycemia and excess lipid intermediates induce the assembly of multi-protein platforms in the cytosol called inflammasomes including the NLRP3 inflammasome.\n\nActivation of the NLRP3 inflammasome activates caspase-1 which its proteolytic activity is responsible for the release of the cytokines IL-1β and IL-18 into tissue and circulating blood.\n\nStrategies that decrease the inflammatory state and the volume of intra-abdominal fat are a therapeutic goal to limit the occurrence of cardiovascular complications and insulin resistance in the obese.\n\nIn this context, it is suggested that reducing the inflammatory response could improve weight loss in obese people. Regular physical activity and a healthy diet have clearly demonstrated anti-inflammatory effects and are effective in weight loss in obese patients.\n\nSeveral epidemiological and clinical studies highlight the potential "health" effects of molecules with anti-inflammatory and antioxidant properties contained in fruits and vegetables, called phyto-micronutrients. In obese patients, phyto-micronutrients such as certain polyphenols of the flavonoid class are beneficial on plasma markers of inflammation, insulin resistance, lipid profile and weight loss. Among legume seeds, Cajanus cajan or pigeon pea represents an interesting variety because of its high content of non-thermosensitive flavonoids of the isoflavone type (genistein and daidzein). In the French Overseas Departments (DOMs).\n\nWe hypothesize that the resumption of adapted physical activity and the reintroduction of polyphenol-rich tropical legume seeds in the diet could bring a benefit in the management of severe obesity in overseas territories by reducing the activation of inflammation mediated by the NLRP3 inflammasome and facilitating the reduction of abdominal visceral fat and weight loss.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'genderBased': True, 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Have a BMI ≥ 35 kg/m² (severely obese)\n* Ability, at the time of inclusion, to follow a personalized physical activity program for 24 weeks.\n* Have agreed to follow-up for up to 36 weeks\n* Be affiliated to a social security system\n* Be able to freely give informed consent (oral)\n\nExclusion Criteria:\n\n* Pregnant woman\n* Have a history of type 1 diabetes\n* Weight \\>150 kg (criterion related to the capacity of the exercise bikes used in the study)\n* History of renal disease \\[glomerular filtration \\< 30 mL/min\\], cardiovascular history of myocardial ischemia (ECG signs), uncontrolled hypertension \\[at rest; systolic blood pressure \\> 140 mm Hg and diastolic blood pressure \\> 90 mm Hg\\], heart failure, cardiac valvulopathy, peripheral arterial disease or arteritis, and stroke.\n* Have an auto-inflammatory or autoimmune pathology known to modify the expression of NLRP3 (cryopyrinopathies, Crohn's disease, gouty arthritis, chondrocalcinosis, arthritic diseases, type 1 diabetes, Biermer's disease, Basedow's disease, rheumatoid arthritis, systemic lupus erythematosus, sclerodermias, non-alcoholic liver steatosis, multiple sclerosis, Alzheimer's and Parkinson's diseases)\n* Have a history of recent (\\<6 months) infectious disease of viral, parasitic, fungal or bacterial origin known to modify the expression of NLRP3\n* Taking medication that may affect weight gain (systemic corticosteroids, psychotropic drugs, migraine medications, beta-blockers, chemotherapy, and antibiotics)\n* Have completed a personalized physical activity program in the 12 weeks prior to inclusion,\n* Have bariatric surgery scheduled within 6 months of inclusion,\n* Have a known intolerance to legume seeds\n* Have an unbalanced low-calorie diet\n* Have consumed dietary supplements containing polyphenols of the flavonoid class (green tea catechins and isoflavones from soy and legume seeds in the 3 months prior to inclusion)."}, 'identificationModule': {'nctId': 'NCT05493592', 'acronym': 'OBESICA', 'briefTitle': 'Pigeon Peas (Cajanus Cajan) : a Natural Anti-inflammatory Facilitating Weight Loss in Obese Patients Returning to Sport?', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital Center of Martinique'}, 'officialTitle': 'Interest of a Diet Rich in Cajanus Cajan (Pigeon Pea) Associated With a Standardized Exercise Protocol on NLRP3 Inflammasome Expression and Weight Loss in Adult Patients With Severe Obesity.', 'orgStudyIdInfo': {'id': '19_RIPH2-29'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'NO_INTERVENTION', 'label': 'Standardized physical activity protocol (EXA control group)', 'description': 'Physical activity protocol for 24 weeks.
