Sort of. WW has charts for for both males and females and all ages, so you can all eat pretty much the same things - no need to cook two dishes. The easiest way would be to have the person(s) following the program to measure their portions according to recommendations, while the other person(s) can have how much as they like of whatever there is. Otherwise the WW program will let you calculate portions for just about anyone (whether they need to lose weight or not), and you can measure it out and divide it upp for all members of the family.
