When I eat water-packed tuna every day for lunch I find good losses on the scale. Kirkland brand from Costco is the best for me as far as quality and taste. I mix in a little mayo and some Mann's Broccoli slaw. This is the only canned fish I like, but hubby who is naturally thin eats, mackerel, salmon, sardines and anchovies and loves it.
The only thought I have is that some time ago they said that tuna had mercury and pregnant women should not eat. I don't know if it is still true.
My goal for 2014 is Fifty Pounds in Fifty Weeks began Christmas 2013
