Brief summary
Aim: To dissociate the effects on plasma concentrations of the inflammatory marker c-reactive protein of a negative energy balance and a reduction in body fat stores. Secondly to compare CRP with fibrinogen and interleukin-6 (IL-6).
Detailed description
Background: Previous epidemiological studies have associated elevated levels of acute phase proteins, mainly C-reactive protein, with cardiovascular diseases (CVD) and cardiac death. Levels of several cy-tokines and acute phase proteins as CRP, haptoglobin and fibrinogen have been found associated with elevated body fat and the risk of diseases associated to the metabolic syndrome. Method: Thirty-six otherwise healthy obese subjects (BMI: 34.23.2 kg/m2, age: 43.410.5 y) participated in a 20-week controlled dietary intervention divided into 4 periods. Weight reduction was induced by an 8-week low caloric diet (LCD) (3.4 MJ/d) followed by a 4-week weight stable maintenance program (M1). Subsequently, they underwent another 4-week LCD (4.2 MJ/d) followed by a final 4-week weight stable maintenance diet (M2). Blood samples and anthropometrical measures were assessed at baseline and after each of the four periods (8, 12, 16 and 20 weeks).
