I'm doing it as is my DH. If you want to do it to the letter, you'd both need plans but we decided just to go for me getting a plan & DH following it. It's not ideal as his macros will be higher than mine, but I've got a fair amount to lose so have quite high macros anyway. I double up on my amounts & then add a bit on for DH. We're both doing well (nearly 9 weeks in) but he's probably had a bigger difference than me (which is so bloody annoying!!!!)
I figured that doing it this way would be easier than having to cook 2 separate meals. There's enough cooking to do as it is without creating more. Don't know how much better he'd be doing if he was eating the correct amounts for him.
