Tuna Over Shakes: The Underrated Protein Hero After Bariatric Surgery
May 06, 2025

When it comes to hitting your protein goals after bariatric surgery, most people reach for protein shakes and trendy powders. But here’s a truth bomb: tuna is the real MVP, and it’s been quietly carrying the weight while others grab the spotlight.
Small Difference, Big Impact
Let’s break it down:
-
Core Power protein shake: 26 grams of protein
-
2.6 oz pouch of tuna: ~21 grams of protein
That’s a 5-gram difference. But when you factor in how long you stay full, how your body digests whole food, and nutrient density—tuna wins hands down.
Protein from real food like tuna takes longer to digest, keeping you fuller longer. Meanwhile, shakes tend to zip right through your new, smaller stomach. That’s not ideal when you’re trying to manage hunger and avoid grazing—a key to long-term weight loss success.
Why Whole Foods Like Tuna Matter After Bariatric Surgery
After surgery, your stomach empties faster. That makes food quality way more important than quantity. Unlike protein shakes, tuna is a complete meal component:
-
Cheap and accessible
-
Packed with omega-3s
-
Portable and no-prep
-
Low-calorie and high-satiety
It’s the kind of food that works for busy people, broke students, hardworking moms, or anyone trying to eat better without stress. No blender needed, no chalky aftertaste—just clean protein.

Skip the Mayo Soup. Give Tuna Some Love.
Let’s be honest: tuna doesn’t get enough credit. While everyone’s hyping overpriced protein powders and bars that taste like disappointment, tuna’s just chilling in a pouch with 20+ grams of protein, minding its own business.
It’s for the girlies who:
-
Eat between Zoom calls
-
Live on meal prep
-
Want something easy, clean, and satisfying
-
Are trying to not eat like an ahole today
Just skip the mayo soup. Dress it up with mustard, pickles, herbs, or serve it straight from the pouch. It’s not glamorous—but it works.
