Abstract

Objective: The objective was to determine the effects of the probiotic, VSL#3, on body and fat mass, insulin sensitivity, and skeletal muscle substrate oxidation following 4 weeks of a high-fat diet.

Methods: Twenty non-obese males (18-30 years) participated in the study. Following a 2-week eucaloric control diet, participants underwent dual X-ray absorptiometry to determine body composition, an intravenous glucose tolerance test to determine insulin sensitivity, and a skeletal muscle biopsy for measurement of in vitro substrate oxidation. Subsequently, participants were randomized to receive either VSL#3 or placebo daily during 4 weeks of consuming a High-fat (55% fat), hypercaloric diet (+1,000 kcal day(-1) ). Participants repeated all measurements following the intervention.

Results: Body mass (1.42 ± 0.42 kg vs. 2.30 ± 0.28 kg) and fat mass (0.63 ± 0.09 kg vs. 1.29 ± 0.27 kg) increased less following the High-fat diet in the VSL#3 group compared with placebo. However, there were no significant changes in insulin sensitivity or in vitro skeletal muscle pyruvate and fat oxidation with the High-fat diet or VSL#3.

Conclusions: VSL#3 supplementation appears to have provided some protection from body mass gain and fat accumulation in healthy young men consuming a High-fat and high-energy diet.
