title: Regular intake of high-oleic peanuts improves fat oxidation and body composition in overweight/obese men pursuing a energy-restricted diet.
abstract: OBJECTIVE
  Evaluate the effect of high-oleic and conventional peanuts within a hypocaloric-diet on energy metabolism and body composition.
  
  
  METHODS
  This 4-week randomized clinical trial included males with BMI of 29.7 ± 2.4 kg m(-2) and aged between 18 and 50 years. Participants were assigned to the groups: control (CT, n = 22) that followed a hypocaloric-diet; conventional peanuts (CVP, n = 22) or high-oleic peanuts (HOP, n = 21) that received the hypocaloric-diet including (not adding) 56 g day(-1) of peanuts. Glucose, fat oxidation, and body fatness and lean mass were the main outcomes.
  
  
  RESULTS
  Body weight and composition did not differ between groups. However, within group total body fat (kg) reduced with CVP and HOP, with a significant decrease in body fat percentage in HOP. While total lean mass (kg) decreased in CT, total lean mass (%) increased in HOP. Truncal lean mass decreased in the CT. At baseline, HOP had greater postprandial fat oxidation than the CVP. After 4-weeks, fasting fat oxidation increased in CVP and HOP. Fat oxidation increased in CT and HOP during the 200 min after meal intake compared to the fasting condition.
  
  
  CONCLUSIONS
  Regular peanut consumption, especially the high-oleic type, within a hypocaloric-diet increased fat oxidation and reduced body fatness in overweigh and obese men.
