How to Make Tuna When on a Diet

Tuna fits into a healthy diet or weight-loss program as a source of lean protein that also supplies vitamin D and omega-3 fatty acids. Canned tuna is a convenient food to keep on hand for a quick meal. The canned version of this seafood also is affordable, making it a budget-friendly diet food. Traditional tuna salad recipes include high-fat mayonnaise that adds unnecessary fat to the dish. Replacing the mayo with a healthier option and bulking up the dish with other nutritious ingredients gives it a makeover fit for any diet.

Drain the water from the canned tuna. Avoid oil-packed tuna that increases the fat content of the dish. Pour the tuna into a large bowl.
