It has been recommended with the BML diet that you feed the mama more. When I increased the amount for everyone, papa was a piggie who ate more than his share, so I did give Keiko special treatment (and hand fed her separately) in addition to putting out the normal portions.
With the back-to-basics BML
plan, there is a specific list of veggies and fruits. The list of veggies includes green beans, peas, carrots, and corn. The list of fruits includes watermelon, melon, cantaloupe, grapes (seedless), apples, blueberries, and pitted cherries. You also don't really need to put extra food out during the day, and you don't really want to mix and match different diet plans.
