Sure, oil-packed tuna has more calories. By some estimates, it’s about 50-70 more calories per can. But here’s the thing: those calories come from healthy fats (if you choose olive oil). Fat makes you feel full. Fat makes your brain happy. Fat is not the enemy—boring food is.
Water-packed tuna is basically a dare. It’s saying, “I bet you can’t make this taste good without 400 calories of mayo.” And you know what? You can’t. So you end up adding more fat anyway. Why not just start with the good stuff?
A studying fact: a 2026 study (yes, someone paid scientists for this) found that oil-packed tuna retained more Omega-3 fatty acids than water-packed. So eating the oil version is actually healthier for your brain. Take that, gym rats!
