BACKGROUND: Exposure to cold is associated with increased energy expenditure to maintain thermal equilibrium. The Cool Fat Burner vest and Gut Buster are chilling devices used to induce shivering and increase calorie use. Drinking chilled water has a similar effect.
METHODS: Indirect calorimetry was performed on volunteers at rest with induced shivering. Eight men and 6 women with a mean age of 32.14+7.26 years were evaluated while wearing the Cool Fat Burner Vest and Gut Buster and drinking chilled water.
RESULTS: Use of the chilling devices was associated with a significant increase in VO2, VT, VE, R, and EE. An over 20% increase in fat use as a fuel source was observed along with a 67% increase in EE. The energy expenditure during the final 30 minutes of shiver chilling was 74.6% above that of the RMR. Chilling induced significant increases in energy expenditure associated with a shift in energy source towards more fat tissue use.
CONCLUSIONS: Indirect calorimetry evaluation of overweight subjects wearing a Cool Fat Burner vest and Gut Buster and drinking chilled water demonstrated significant increases in oxygen uptake and energy expenditure, and a shift in fuel utilization towards fat as the substrate of choice.
