Tag: Tuna in oil vs water

According to nutritional data, most plain canned fish, like tuna and salmon, contain zero carbohydrates, making them a staple on the ketogenic diet. This makes canned fish not only a convenient, protein-packed meal option but also an excellent source of healthy fats for those following a low-carb, high-fat lifestyle.

According to USDA data, a 1/2 cup serving of canned light tuna in water, drained, contains about 66 calories. Knowing precisely how many calories are in 1/2 cup of canned tuna is crucial for anyone monitoring their intake, as the calorie count can vary significantly based on how the fish is packed.
