Per typical serving

With typical servings, 60 g (2 oz) of canned tuna has about 70 kcal and 15.3 g of protein, and 80 g (3 oz) of canned jack mackerel about 125 kcal and 18.6 g.

To get 20 g of protein you would need about 78 g of canned tuna (91 kcal) or about 86 g of canned jack mackerel (134 kcal).

The typical serving is a common amount used for the math, not a recommendation. Ounces are rounded US equivalents; the values come from the database entries cited in the sources.

Which is more filling?

By our estimate, canned tuna is more filling per calorie than canned jack mackerel: 5 versus 4 out of 5.

  • Canned tuna: Low energy density; a lot of protein per calorie; high water content.
  • Canned jack mackerel: Calculation: 1 (base) + 1 (low energy density: 156 kcal/100 g) + 2 (protein: 14.9 g/100 kcal) + 0 (fiber: 0.0 g/100 kcal) + 0 (solid food with 69.2 g of water, under 70) = 4.

The 1 to 5 score is our own estimate: it starts at 1 point, adds points for low energy density, for protein and fiber per 100 kcal, and for the water in solid foods, and subtracts points for drinks with calories. It is useful for comparing foods with each other; it is not a measurement in people.

When to choose each one

Canned tuna

  • If you want more protein per calorie: 22 g per 100 kcal.

  • If you prefer a lighter typical serving: about 70 kcal in 60 g (2 oz).
  • If you have nausea or fill up quickly: it carries our “Easy to digest” tag.

Canned jack mackerel

  • If you want more protein in a typical serving: 18.6 g in 80 g (3 oz).

On a GLP-1 medication

Canned tuna. “High in protein”: plenty of protein per calorie; protein helps preserve muscle mass when you eat less. “Easy to digest”: a soft or low-fat food that many people tolerate well when they feel nauseous or get full quickly. “Nutritious in small servings”: a lot of nutrition in a small volume, which is practical when you eat little.

Canned jack mackerel. “High in protein”: plenty of protein per calorie; protein helps preserve muscle mass when you eat less. “Nutritious in small servings”: a lot of nutrition in a small volume, which is practical when you eat little.

These are general guidelines, not medical advice: everyone tolerates foods differently.
