The effects of two weeks of overfeeding with peanut butter modified with cylodextrins on body composition and metabolism: A double-blind, placebo-controlled, crossover, pilot trial

Abstract

The purpose of this pilot study was to examine the effects of a hypercaloric diet with regular peanut butter (HC + RPB) versus a hypercaloric diet with modified cyclodextrin based peanut butter (HC + MPB) on body composition and metabolism. The study was a crossover design using 6 healthy male subjects. Fat mass significantly increased from Pre- to Post-Test in the HC + RPB condition (p<0.05, mean = +1.00kg, 95% CI: 0.11 to 1.88kg) whereas no significant changes were demonstrated in the HC + MPB condition. Additionally, the relative Pre-Test to Post-Test percent change was significantly greater in HC + RPB (p<0.05, mean = 6.04%g) compared to HC+MPB. There were no significant changes in metabolism or lean mass. Here we demonstrate that adding modified cyclodextrins to peanut butter may prevent short-term fat gain with moderate overfeeding.
