Ideally not, particularly not in attack. If they cook so much better than when we plain roast one of our own, it's for a reason! They baste them constantly and, even after removing the fat, they're still fattier than your own cooked ones. (Better than some other things you could eat though!)
I don't know how much weight you have to lose (you could perhaps update your statistics) but your attack period is the kick off which will give you the encouragement to see you through the weeks in cruise where perhaps you won't see such a great loss always. Keep it clean.
All pork, including ham, is banned in the original French diet so I tend to keep away mainly...
