You need to change the superpose.line setting:
xyplot(Choline ~ time,
groups=BMI,
data=data,
type="l",
scales=list(relation="free"),
auto.key=list(title="BMI Group",
border=FALSE, lines=TRUE, points=FALSE),
xlab=c("Point in Time"),
ylab=c("Concentration of Choline"),
par.settings = list(superpose.line = list(lwd=3)))

library(lattice)
data <- data.frame(cbind(1:2,c(1,1,2,2), c(0.5,0.9,1.0,1.8)))
names(data) <- c("BMI","time","Choline")
data$BMI <- factor(data$BMI)
levels(data$BMI) <- c("<=17.5",">17.5")
data$time <- factor(data$time)
levels(data$time) <- c("Admission","Discharge")
#Show names of settings
names(trellis.par.get())
#Try to set the line width of the two plotted colored lines
line<-trellis.par.get("plot.line")
line
line$lwd=3
trellis.par.set("plot.line", line)
line
#Without group option: Line width is changed
xyplot(Choline ~ time,
data=data,
type="l",
scales=list(relation="free"),
auto.key=list(title="BMI Group", border=FALSE),
xlab=c("Point in Time"),
ylab=c("Concentration of Choline"))
#With group option: Line width is not changed
xyplot(Choline ~ time,
group=BMI,
data=data,
type="l",
scales=list(relation="free"),
auto.key=list(title="BMI Group", border=FALSE),
xlab=c("Point in Time"),
