The effect of thermogenic meal replacement beverages (TMRB) containing 90 mg EGCG and 100 mg of caffeine on resting energy expenditure (REE) was tested. Thirty adults (19 women, 11 men) were stratified into 3 groups: lean (n=10, BMI 21.5 ± 2.1); overweight/obese (OW) (n=10, BMI 29.8 ± 2.7); or weight maintainers (WM) (n=10, BMI 28.8 ± 4.0). Following an overnight fast, baseline measurements, including REE via indirect calorimetry, were performed. REE was repeated at 30, 60, 90, and 120 minutes after consuming a TMRB. Appetite was assessed via visual analogue scale at baseline, 30 minutes and 120 minutes after the TMRB. Mean 24-hour REE was increased 5.9 ± 2.5% overall (p=0.000), 5.7 ± 3.1% among lean subjects (p=0.0002), 5.3 ± 1.4% among OW subjects (p=0.000), and 6.8 ± 2.7% among WM (p=0.0007). Appetite was significantly reduced 30 minutes after the TMRB (p=0.0002). TMRB appear to be a promising weight control tool.
