I also eat both servings (:-p) and just log it accordingly

I eat both and count the calories.

I eat 1 serving, about 3 oz. of tuna. It is plenty for a salad or sandwich for me. It wasn't what I was eating that made me fat - it was how much. I found I can be satisfied with a lot less food than I thought by only eating 1 portion and then having more vegetables if I am still hungry.

I always eat 4 servings of canned light tuna in water. It only comes out to 240 calories.

I eat the entire can and count the calories. When I eat it it's mostly for the protein. I put dill relish in it and put it on 85 grams of romaine lettuce. 255 calories and sustains me for 2-3 hours. I have eaten only one serving until I realized the amount of protein. My body responds well to protein.

Me too.

I don't eat the whole can but no matter what I eat, I count the calories, so that applies if I eat all of it. Good luck on trying out calorie counting! I love it.

I usually make a tuna/egg salad (with 2 cans) for a sandwich and split it up for 4 servings. So while i eat a serving of tuna, i also have an egg and some veggies mixed in :)

Sometimes I eat both servings, sometimes I share.;)

Growing up my mom used one can to make tuna salad and it fed all of us. Our portions have certainly grown.
