Seafood is often assumed to be expensive, but several seafood options are both affordable and exceptionally effective for the ketogenic diet. When selected strategically, low-cost seafood provides high-quality protein, essential fats, and micronutrients that balance meat-heavy keto routines—all without increasing grocery expenses.
This guide explains how to identify low-cost seafood that fits keto macros, supports metabolic health, and integrates seamlessly into a budget-conscious ketogenic plan.
Why Seafood Is Valuable in a Budget Keto Diet
Seafood offers nutritional advantages that land-based proteins cannot fully replace. Even inexpensive options contribute omega-3 fats, iodine, selenium, and highly bioavailable protein.
Metabolic Benefits on Keto
