Zero-Carb Snacks for Intermittent Fasting and Busy Days

November 1, 2025Tuvy Lemberg

If you're doing intermittent fasting, keto, carnivore, low-carb, or just trying not to inhale a sleeve of cookies every afternoon, then you already know:

Zero-carb snacks are the holy grail.

But like most holy things, they’re VERY hard to find.

Most “healthy” snacks sneak in carbs through:

  • starches,
  • sneaky sugars,
  • fiber blends pretending not to be carbs,
  • or “natural flavors” that are anything but.

And when you’re in a fasting window or running through the day like a caffeinated tornado, the last thing you want is a snack that:

  • spikes your insulin,
  • breaks your fast,
  • or sends you sliding into a carb crash.

So today we’re breaking down the BEST zero-carb snack options — especially the clean, kosher-friendly ones — and why Primal Krisp is sitting comfortably at the top of the list.


What Exactly Counts as a Zero-Carb Snack?

Let’s start here, because “zero carb” gets thrown around a LOT.

A true zero-carb snack MUST be:

  • 0–1g total carbs (no net-carb marketing tricks)
  • no added sugars
  • no starches or fillers
  • no fake fibers labeled as 0g carbs “because we said so”

No games. No loopholes. No nonsense.


Why Zero-Carb Snacks Are So Important for Intermittent Fasting

You might not be eating during a fast… but you ARE living a full day.

And that comes with challenges:

✔️ Hunger Waves

They hit. They’re real. And they don’t care about your fasting schedule.

✔️ Energy Dips

Your body needs protein to stay steady — not carbs that spike & crash you.

✔️ Cravings

Sugar cravings during fasting are like pop-up ads for foods you didn’t even like as a kid.

✔️ Busy Days

Sometimes you’re fasting AND running around AND trying to be a functioning human… you need backup.

This is where zero-carb snacks shine — when used intentionally.

Depending on your fasting style, many people allow:

  • clean proteins (like meat chips)
  • electrolytes
  • zero-sugar foods
  • very low-calorie options

Zero-carb foods help maintain blood sugar stability without kicking you into a hunger spiral.


The Best Zero-Carb Snacks (Ranked)

Here are your top options — and yes, most of them are underwhelming until you get to number 1.

5. Hard-Boiled Eggs

High protein? Yes.
Convenient? Debatable.
Portable? Only if you like living dangerously.

Eggs are great… but not exactly a “grab-and-go” snack for fasting windows.

4. Tinned Sardines or Tuna

Super nutritious. Zero carbs. Also smells like a decision you’ll regret.

Great at home. Not so great in the car, office, airplane, shul, gym… anywhere else, really.

3. Cheese Crisps (If You Do Dairy)

Crunchy, low carb, satisfying.

But:

  • they melt in heat,
  • get greasy,
  • and contain anti-caking agents that aren’t as “clean” as advertised.

Not ideal for clean fasters.

2. Pork Rinds (If You Eat Them)

Technically zero carb, but many brands use:

  • seed oils,
  • MSG,
  • flavor powders,
  • preservatives.

Also NOT kosher… so let’s just move on.

1. Meat Chips (The KING of Zero-Carb Snacks)

Crunchy. Protein-packed. Satisfying. Clean. Zero carbs.

Especially when the brand is Glatt Kosher and actually uses real meat with no preservatives, no sugar, no oil, and no fillers.

And yes… that would be Primal Krisp.


Why Meat Chips Are the Ultimate Zero-Carb Snack

Here’s why meat chips dominate this category:

  • 0–1g total carbs
  • High protein
  • Real meat
  • Real crunch
  • No sugar
  • No preservatives
  • No oils
  • No dairy
  • No fillers

They're one of the only zero-carb snacks that:

  • don’t melt,
  • don’t smell weird,
  • don’t get messy,
  • don’t break your fast (for most fasting approaches),
  • and don’t spike hunger or cravings.

Plus — they’re truly delicious.


Zero-Carb Snacking While Fasting (How to Do It Right)

Depending on your fasting style, here’s how meat chips often fit in:

✔️ OMAD (One Meal a Day)

A few chips can help you push through hunger waves before your eating window.

✔️ 16:8 Fasting

Great to keep blood sugar steady in the final hours before your first meal.

✔️ Clean Fasting (Strict)

You’ll want to avoid all calories — even meat chips.

But many clean fasters keep meat chips on hand for after their fasting window so they don’t break their fast with carbs.

✔️ Flexible Fasting

Zero-carb protein is often allowed because it:

  • doesn’t spike insulin,
  • satisfies hunger,
  • helps maintain discipline.

Why Primal Krisp Is the Best Zero-Carb Snack for Fasting Days

Let’s get straight to the point.

Primal Krisp = the cleanest zero-carb snack you can put in your body.

  • Brisket Krisps — rich, fatty, satiating, perfect for hunger control
  • Chicken: Original — clean, lean, pure protein with 0 carbs
  • BBQ Chicken Krisps — bold flavor, zero sugar (rare in BBQ snacks!)

You literally cannot go wrong.


Final Verdict: Zero-Carb Snacking Doesn’t Have to Be Boring

  • sad boiled eggs,

  • tuna cans in public,
  • or jerky that hurts your jaw.

Not anymore.
