Protein is the least flexible macro on keto. You need enough to preserve muscle and produce satiety, but not so much that ketones dip. Choosing quality sources makes this much easier.

Beef and lamb

  • Ground beef 80/20 — the workhorse of keto cooking
  • Ribeye and chuck roast — fatty, flavorful
  • Lamb shoulder and chops — nutrient-dense
  • Organ meats (liver, heart) — highest micronutrient density on the planet

Poultry

  • Chicken thighs (bone-in, skin-on) — cheap, forgiving, fatty
  • Whole roasting chicken — one bird, three meals
  • Duck breast — high fat, luxurious flavor
  • Turkey (whole or ground) — lean, add fat when cooking

Seafood

  • Wild salmon — omega-3s, vitamin D
  • Sardines — cheap, calcium-rich
  • Mackerel — highest omega-3 content
  • Shrimp — quick-cooking, lean
  • Scallops — expensive but low-carb (occasional treat)
  • Tuna (fresh or canned) — versatile, lean

Eggs and dairy

  • Whole eggs — cheapest complete protein
  • Full-fat Greek yogurt
  • Cottage cheese
  • Hard cheeses

Plant proteins (for keto-vegetarians)

  • Firm tofu
  • Tempeh (higher carb, portion carefully)
  • Seitan (only for non-gluten-free)
  • Hemp seeds

Deli meats

Fine, but read labels — many are cured with sugar, honey, or maple. Look for brands like Applegate Naturals or ask your deli counter for uncured, unsweetened options.

Frequently asked questions

How much protein per meal?

About the size and thickness of your palm — roughly 30 g for most adults.

Is grass-fed worth it?

Nutritionally slightly better; environmentally usually better; taste often better. Prioritize based on budget.
