Change in plasma lactate level compared with baseline (n=159)

Diet	β (95% CI)	P value
CG	−0.10 (−0.18 to −0.02)	0.012
Cg	−0.18 (−0.27 to −0.09)	<0.001
cG	−0.20 (−0.29 to −0.11)	<0.001
Cg	−0.18 (−0.26 to −0.11)	<0.001

Participants had a baseline lactate level of 1.2 mmol/L (SD: 0.5).

P value refers to the p value for linear regression based on a repeated measures analysis.

β, beta coefficient; CG, high carbohydrate, high glycemic index diet; cG, low carbohydrate, high glycemic index diet; Cg, high carbohydrate, low glycemic index diet; cg, low carbohydrate, low glycemic index diet.
