Catalina Crunch went from Shark Tank reject to keto cereal cult favorite. But here’s the thing nobody wants to say out loud: keto cereal is still keto cereal. We bought the hype, tried the lineup, and have real thoughts.
TL;DR Verdict
Catalina Crunch | ⭐ 3.8/5 | $8-10 per 9oz bag
It’s the best keto cereal we’ve tried — but that’s a low bar. The crunch is legitimately good, the flavors are bold (Cinnamon Toast is the standout), and the macros are impressive. But there’s no escaping the stevia aftertaste, the high price, and the fact that it can wreck your stomach if you’re not used to the fiber. If you’re strict keto and miss cereal, this is your best option. If you’re just looking for a healthy breakfast, regular oatmeal is cheaper and easier.
Nutrition Facts
| Per Serving (1/2 cup) | Catalina Crunch | Frosted Flakes |
|---|---|---|
| Calories | 110 | 140 |

| Net Carbs | 5g | 34g |
| Fiber | 9g | 0g |
| Sugar | 0g | 12g |
| Fat | 6g | 0g |
The macros are genuinely impressive. 11g protein and 9g fiber in half a cup is rare for any cereal, let alone one that’s keto-friendly. Zero sugar. No artificial flavors. Made with plant proteins (pea, potato, rice).
The Full Product Lineup
Catalina Crunch has expanded way beyond cereal. Here’s everything they make:
Cereals (The OG)
12 flavors including Cinnamon Toast, Dark Chocolate, Fruity, Honey Graham, Maple Waffle, Chocolate Peanut Butter, and more. These are what put them on the map.
Sandwich Cookies
Keto Oreo alternatives. Chocolate Vanilla, Chocolate Mint, Peanut Butter. 2g net carbs per cookie. Reddit consensus: these are actually really good — possibly better than the cereal.
Crunch Mixes
Trail mix-style snacks with the cereal pieces, nuts, and seeds. Better as a snack than cereal, honestly.
Flavor Rankings (We Tried Them All)
| Flavor | Our Rating | Notes |
|---|---|---|
| Cinnamon Toast | ⭐⭐⭐⭐⭐ | Best one. Closest to real cereal. |
| Chocolate Peanut Butter | ⭐⭐⭐⭐ | Solid. PB flavor is subtle. |
| Honey Graham | ⭐⭐⭐⭐ | Surprisingly good. |
| Fruity | ⭐⭐⭐⭐ | Tastes like Fruity Pebbles cousin. |
| Maple Waffle | ⭐⭐⭐ | Decent, a bit artificial. |
| Dark Chocolate | ⭐⭐ | Stevia taste very strong. |
| Apple Turnover | ⭐⭐ | Weird artificial flavor. |
What We Liked
✅ Actually Crunchy
Unlike most keto cereals that turn to mush instantly, Catalina Crunch stays crunchy in milk for 5-10 minutes. That’s legitimately impressive.
✅ High Protein
11g protein per serving is wild for cereal. Most regular cereals have 1-3g. This actually keeps you full.
✅ Bold Flavors
The flavors aren’t subtle. Cinnamon Toast actually tastes like Cinnamon Toast Crunch. Fruity actually tastes like Fruity Pebbles. That’s rare for “healthy” cereal.
✅ Zero Sugar
Sweetened with stevia and monk fruit. No blood sugar spike. Actually keto-compliant.
What We Didn’t Like
❌ The Stevia Aftertaste
Let’s be real: if you’re sensitive to stevia, you’ll taste it. Some flavors (Dark Chocolate) are worse than others. It’s not horrible, but it’s there.
❌ Digestive Issues
9g fiber per serving is A LOT. Multiple Reddit users reported bloating, gas, and stomach issues. The brand even warns about this on their FAQ. Start with a small serving.
❌ Expensive
$8-10 for a 9oz bag. That’s 4-5 servings. Roughly $2 per bowl. Regular cereal is $0.30-0.50 per bowl. You’re paying a premium.
❌ Small Serving Size
Half a cup looks sad in a bowl. Most people eat 1-1.5 servings, which doubles the carbs and cost.

Pro Tips
- Try it with Greek yogurt first — better crunch retention and extra protein
- Start with Cinnamon Toast — it’s the most universally liked flavor
- Small serving first — the fiber can cause digestive issues if you’re not used to it
- Buy at Costco — cheaper than Amazon or direct
- Try the cookies — many say they’re better than the cereal
Who Should Buy Catalina Crunch?
Buy it if:
- You’re strict keto and genuinely miss cereal
- You want high-protein breakfast that’s not eggs
- You can tolerate stevia and high fiber
Skip it if:
- You’re not strictly keto (regular oatmeal is cheaper/easier)
- You hate stevia aftertaste
- You have a sensitive stomach
- You’re on a tight budget
Final Verdict
Catalina Crunch is the best keto cereal on the market — but that’s a bit like being the tallest person in the room of short people. It’s genuinely crunchy, the protein is impressive, and the Cinnamon Toast flavor is actually good. But you’re paying $2+ per bowl for something that still tastes like “healthy cereal” with a stevia aftertaste.
For strict keto dieters who miss cereal? Absolutely worth trying. For everyone else? There are cheaper ways to eat breakfast.
Our rating: 3.8/5 — Best in class for keto cereal, but that class has a low ceiling.
