---|---|---|---|
Heilbronn et al. (4), n = 45, 4 wks on weight loss diet followed by 8 weeks on weight loss diets of low or high GI | 6.7%, after 4 wks of weight loss diets: 6.65 vs. 6.35% | 6.04 vs. 6.06% | After implementation of the GI diets, a 0.6% decrease in low GI, not significantly different than high-GI diet; no difference in weight loss from low- vs. high-GI diets |
Gilbertson et al. (10), n = 104, 52 weeks | 8.3 vs. 8.6% | 8.0 vs. 8.6% | 0.3% decrease in low-GI group, although reported GIs were the same in both groups at study end |
Giacco et al. (11), n = 63, 24 weeks | 8.8 vs. 8.8% | 8.6% (compliant group) vs. 9.1% | 0.2% decrease in low-GI compliant group |
Brand et al. (12), n = 16, 12 weeks | 7.7 vs. 7.7% | 7.0 vs. 7.9% | 0.7% decrease in low-GI group |
