Eating behavior-advice?

Hi!  I have two 5-month litter mates, a male and female.  The female eats only a few bites of food before giving it up to the male, who happily licks both plates clean.  The result is that he is getting chubby and I think she may not be getting enough to eat.  I've tried feeding them in separate rooms but she will not eat a bite unless she can see him.  Can anyone offer advice on how to resolve this? Thanks!

Try feeding half a serving, then give more when he's had his fill to see if she'll eat that?  

Thanks!  I'll see if that works--if he will ever have his fill!  

Separate feeding. Feed the girl first with the male in the other room. Then when she's full. Let him go to town.
