Today in Brazil, 6.9% of the population has Diabetes Mellitus 2 (DM2). In the world, there are about 422 million people with DM2. It is a chronic disease of the endocrine system, accounts for 90 to 95% of cases of DM2 and is characterized by defects in insulin action and secretion. Its main cause is linked to obesity and insulin resistance. Obesity is a chronic, multifactorial disease - environmental, nutritional and genetic factors - characterized by excessive accumulation of body fat, and is reaching epidemic proportions, more than 100 million children and 600 million adults worldwide. The number of obese people in Brazil reaches 17.9% of the population.

Rates of obesity and DM2 have increased in the last decades, both diseases being associated with inflammation and specific alterations in the intestinal microbiota. Thus, studies show that the use of probiotics may be associated with reduced body weight and reduced glucose in the bloodstream. Probiotics are living microorganisms that, when administered in suitable dosages, confer benefits to the health of the host. In addition, studies show the relationship of the intestinal microbiota and the emergence of various diseases and demonstrate that probiotics can control inflammatory processes, metabolic dysfunctions, normalization of stress-induced behaviors, regulation of the hypothalamic-pituitary-adrenal axis and neuropsychiatric disorders. Thus, the importance of investigating the ingestion of probiotics in relation to anthropometry, biochemical profile and anxiety in diabetic and overweight individuals with cardiopathy are justified. It is a randomized, double-blind, controlled clinical trial. The study will last 3 months and will occur with 74 adult individuals (between 20 and 60 years) of the SUS outpatient clinic of the Institute of Cardiology of Porto Alegre - RS, of both sexes, with BMI above 25 m² / kg. and less than 40 m² / kg, divided into 2 groups and 37 individuals per group. These patients were: Group A (intervention: n = 37): patient received 1 sachet per day of probiotics Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus lactis, Bifidobacterium lactis and Bifidobacterium bifidum for 90 days and Group B (placebo; n = 37): microcrystalline cellulose, lactose, pregelatinized maize starch. Probiotics will contain a dose of 109 CFU in each strain. The excipients used will be: microcrystalline cellulose.
