Interactions between genes and environment, i.e. our inherited responses to environmental changes, may be crucial in the development of the common diseases. The investigators were the first to identify PPARG gene as risk gene for type 2 diabetes. The role of the Pro12Ala polymorphism in diabetes risk has also been verified in meta-analysis. However, this effect on seems to depend on intervention and age. In this study the effects of diets high with saturated fatty acids (SAFA) and polyunsaturated fatty acids (PUFA) are compared in subjects carrying either Pro12Pro or Ala12Ala genotype of the PPARG gene. Aim of the study: To test if subjects with Pro12Pro and Ala12Ala genotypes respond differentially to a diet supplemented with high saturated (SAFA) or polyunsaturated fat (PUFA). Hypotheses: 1. Specific: Subjects with the Ala12Ala genotype will be more sensitive to dietary modification, and therefore respond more favorably to PUFA diet 2. More general: Dietary instructions individually tailored according to the genotype would allow better treatment of obesity and diabetes

It is a multifactorial disease that involves genetic and environmental factors that lead to increased mortality from cardiovascular disease, diabetes, cancer, among others and impairs life quality. Most research on severe obesity focuses on surgical alternatives and their results, thus this clinical trial aims to evaluate the effect of a non-pharmacological approach based on nutritional intervention and supplementation with a functional food, the olive oil. It will analyze the effectiveness of interventions on: weight loss, improvements on body composition and inflammatory profile (TNF-alfa, interleucins 1, 6 and 10, adiponectin), insulin resistance and serum lipids control, changing eating habits and physical activity practice, modification on bone mineral density and sarcopenia, and reduction of cardiovascular risk and other diseases. Also, it will be investigated the influence of polymorphisms (Pro12Ala of PPAR-γ gene, -174G>C of IL6 gene e Trp64Arg of ADRB3 gene) on nutritional intervention effectiveness with and without olive oil. This research looks for improving severely obese patient's care and contributing to effective results by reducing costs and risk treatment. The investigators believe that this informations will contribute significantly to the scientific field, expanding the knowledge about severe obesity.

Description: The procedure used for analysis is done using a Dual Energy Radiological Absortiometry (DEXA) equipment. The measurement of the body fat and fat free mass percentage measure is obtained by means of a full body scan using the LUNAR PRODIGY DF + 14.319 Radiation (Madison, WI) brand device, following manufacturer's protocols. The body mass is evaluated by means of a balance (Sanny®, São Bernardo do Campo - São Paulo, Brazil), with the volunteer barefoot and in orthostatic position using a Toledo scale sensitive to 100 g. The stature is evaluated by a stadiometer with a tape calibrated at 0.1 of the same mark. Waist circumference and other body perimeters are measured with a 0.1 cm Anthropometric Tape (Sanny®, São Bernardo do Campo - São Paulo, Brazil). Weight and height data are used to calculate BMI using the equation adopted by the WHO: BMI = (Weight / (Stature) 2).
Measure: Body Composition. The changes are being evaluated. Time: Before the intervention protocol and 48 hours immediately after the last exercise session.Description: The metabolic rate was measured using a gas spirometry analyzer. After having fasted from 8:00 pm the previous day, the volunteers were referred to the laboratory shortly after the awakening and were invited to remain seated in a thermoneutral environment for 30 minutes. For the next 30 minutes, VO2, VCO2, VE and RER were monitored until variations of no more than 10% occurred when five-minute intervals were compared. Once this steady state was obtained, these variables were recorded for five minutes. The calculation of the resting metabolic rate is done according to Macdonald (1990).
