THE CARNIVORE DIET BENEFITS
You survived 16 hours without eating, and the first thing you reached for was a granola bar with 14 grams of sugar. That's not how intermittent fasting snacks are supposed to work. Your eating window is compressed, so you really need the best high-protein snacks for intermittent fasting.
Look no further.
We’ve created a list of our favorite healthy intermittent fasting snacks in the world - savory meat chips, certain cheese, hard-boiled eggs, nuts and seeds, and a few other standouts. Find your new favorite go-to snacks below.
Key Takeaways
- Intermittent fasting snacks belong only in your eating window - any calories break a fast.
- Protein and fat keep you full into your next fasting stretch. Carb-heavy snacks spike insulin and burn fast.
- The best high-protein snacks for intermittent fasting pack the most nutrition per calorie.
- Meat chips and eggs lead the pack, with hard cheese and nuts close behind.
- Snacks during intermittent fasting should be intentional - don’t turn your entire eating window into an eight-hour graze.
Understanding Intermittent Fasting
Most people doing intermittent fasting land on one of a few common setups.
- 16:8 is the most popular. 16 hours fasted, 8 hours eating.
- 20:4 shrinks that window to four hours.
- 5:2 involves eating normally five days a week, then dropping to 500-600 calories on the other two.
- OMAD (one meal a day) puts everything in a single sitting.
Each version shifts how much room you have for healthy intermittent fasting snacks. The tighter the window, the more every bite counts.
What Actually Breaks a Fast?
The short answer is calories. Anything your body metabolizes for energy pulls you out of the fasted state. Water won't break your fast, and neither will black coffee or plain tea as long as you're not adding anything.
Beyond that, you're eating.
Some people argue bone broth or a splash of cream “doesn't count,” but if it has calories, your body processes them regardless. 10 calories won't trigger the same insulin response as 400, but calories in means fast over.
So Can You Enjoy Snacks During Intermittent Fasting?
During your eating window - absolutely. The question isn't whether you're allowed to eat snacks during intermittent fasting, it's whether what you're choosing actually helps.
A bag of pretzels technically fits inside your window, but it burns through fast and spikes your blood sugar, leaving you hungrier than before. The best approach to snacks during intermittent fasting is treating them like fuel for the next fasting stretch - high in protein with enough fat to keep you full.
That makes the next fasting stretch easier to start. Load your eating window with whole food snacks that actually do something for you and the fasting hours handle themselves. So, what are the best high-protein snacks for intermittent fasting?
Healthy Intermittent Fasting Snacks You Need in Rotation
We handpicked six snacks worth enjoying during your eating window. These healthy intermittent fasting snacks are all protein-forward and low in sugar. They’ll keep you full through your next fasting block instead of leaving you watching the clock.
Carnivore Snax Meat Chips
These are by far the best high-protein snacks for intermittent fasting. They’re carefully crafted from just two ingredients - meat and salt. That’s it.
Every bag starts as a full pound of regeneratively raised meat, gently dehydrated at low temperature with Redmond Real Salt into something that dissolves on contact - crispy outside, gone the second you eat it. There are so many amazing varieties to choose from:
- Ribeye Chips: The flagship. The fat cap goes from crispy to velvety in about half a second, with beef flavor dense enough to feel like a meal in chip form.
- Brisket Chips: Hit the spot when you want something deeper and smokier.
- Pork Chips: Bring heritage pork in a format that tastes like crispy pork belly without the grease. Our take on pork rinds.
- Steak Chips: Made from succulent New York strip - the leanest beef option if you're watching fat intake during your window.
- Chicken Chips: Pasture-raised, lightest of the lineup, and the most protein per calorie.
A few common themes across the board - zero carbs and sugar means no insulin spike when you break your fast. Just clean protein your body puts to work immediately. If you want an alternative to whey protein that doesn't come in a plastic tub, this is it.
Other Meat Snacks That Work
Jerky and biltong both fit inside an IF eating window - but you have to read the label first. Most commercial jerky is loaded with sugar, which defeats the purpose of choosing protein-dense intermittent fasting snacks.
Biltong tends to be cleaner since it's air-dried without the sweet marinades most jerky brands lean on. Meat sticks are an option too - just look for the shortest label you can find.
Jerky and biltong also double as healthy shelf-stable snacks that don't need a fridge - useful if your eating window hits while you're at work or on the road. But the truth is, your search for the best meat snacks ends with Carnivore Snax meat chips.
Certain Cheeses
Hard cheeses like cheddar and parmesan pack more protein per ounce than most people expect, and they sit at almost zero carbs. A couple ounces of sharp cheddar between meals gives you 14g of protein and keeps you full without any blood sugar disruption.
String cheese works if you want something grab-and-go. The fat content slows digestion and extends satiety into your fasting hours - exactly what you want from your last snack before the window closes. Cheese fits neatly into the high-fat low-carb snacks category that IF pairs best with.
Hard-Boiled Eggs
Roughly six grams of protein per egg with practically no carbs, and you can batch-cook a week's supply on Sunday and forget about them until cravings strike.
Hard-boiled eggs are one of the most efficient intermittent fasting snacks on the board - cheap and portable if your eating window hits while you're out. Two eggs with salt gives you 140 calories and 12g of protein. Hard to beat that ratio for the price.
Eggs sit right there among the best low-calorie snacks that still deliver real nutrition and satisfaction (with the right seasoning) if you’re trying to watch your overall intake.
Nuts and Seeds
Almonds and walnuts are the anchors here. They’re calorie-dense but worth it when you're working inside a tight eating window and want some healthy plant-based fat and protein to keep you full.
Portion control is the only thing to keep an eye on. A handful is a snack, half a jar is a meal you didn't mean to eat. Pistachios in the shell help with this, because the shelling slows you down enough to notice when you've had enough.
If you're eating keto or paleo alongside IF, nuts are the crossover snack that works for both and rank among the most reliable paleo snacks you can stash in a desk drawer or gym bag.
Nut Butter With Veggies
Almond butter or natural peanut butter spread on celery and bell pepper strips is the snack that doesn't feel like you're trying too hard. The fat from the nut butter keeps you full while the vegetables add volume and fiber without many calories. Takes about 30 seconds to throw together.
Our advice? Go natural on the nut butter. The ingredient list should be nuts and salt, nothing else. It probably has sugar and palm oil if it pours easily out of the jar. Pre-slice your vegetables before your eating window opens so you're grabbing and eating, not prepping.
Tips on Keeping Your Snack Habit in Check
Having the right healthy intermittent fasting snacks on hand is only useful if you don't spend your entire eating window grazing through them. Some people respond to a shorter window by cramming food into every available minute - eat a real meal at the start of your window instead.
Protein and fat first sets the baseline, and the best high-protein snacks for intermittent fasting are a bridge between meals or before your window closes. NOT a meal replacement.
Practice portion control, too. You WILL eat more than you intended - every time - if you're pulling almonds straight from a full bag or scooping nut butter from the jar. Measure out your snack and put the bag away before you start eating.
Your standards for what earns a spot in your snack arsenal tight on a cut. Nuts and cheese still work in moderation, but portions have to be honest. Leaner picks like eggs and chicken chips are exactly the kind of cutting snacks that keep you in line without burning your daily budget on one handful.
Watch what you're drinking during fasting hours, too. A “small” latte with oat milk is 150+ calories that breaks your fast whether you like it or not. Save those calories for high-protein snacks that actually move the needle when your eating window opens.
Final Words on the Best High-Protein Snacks for Intermittent Fasting
Your eating window is limited real estate, and the worst thing you can do with it is fill it with empty calories that leave you hungrier an hour later.
Every snack on this list earns its place because it delivers protein that holds you through fasting hours - backed by fat to keep you full without the sugar spike that undercuts your next stretch.
Stock your fridge with healthy intermittent fasting snacks that work for your schedule instead of against it. Carnivore chips were built for when you want the shortest ingredient list on this page with zero carbs and plenty of protein, ready to eat straight from the bag.

Frequently Asked Questions
When can you eat snacks during intermittent fasting?
Only during your eating window. If you're on a 16:8 schedule, that means your snacks during intermittent fasting go in the eight-hour block - not during the 16 hours of fasting.
What are the best high-protein snacks for intermittent fasting?
Meat chips and hard-boiled eggs give you the best protein-to-calorie ratio. Hard cheese holds its own, too. Jerky or biltong works if the label is clean. Nuts round it out as long as you control portions.
What food does not break intermittent fasting?
Water and black coffee are the safe bets. Plain tea without anything added works too. Some people include bone broth, but it technically has calories, so purists would say it breaks a fast.
Does popcorn fit into an intermittent fasting regimen?
Sure - during your eating window. Popcorn is mostly carbs with almost no protein, though, so it burns fast and won't carry you through your next fasting stretch. Air-pop it yourself and keep portions small if you go that route. Pair it with plenty of protein in other IF snacks.
How do I stop snacking all the time?
Eat more protein at your actual meals. Most people who graze nonstop during their eating window aren't getting enough protein or fat at meal time, so they're hungry again 45 minutes later. Front-load your window with a real meal and the impulse quiets down. Staying hydrated helps, too.
