Keto, Insulin, and Maltitol: The Science Every Type 2 Diabetic in Germany Needs to Know
You’re standing in Edeka. One hand on your shopping basket, the other holding a “keto-friendly” chocolate bar. The Traffic Light label looks green-ish. No added sugar. Sweetened with maltitol. Sounds safe—right?
If you’re a Type 2 diabetic living in Germany, following keto to control insulin, this moment matters more than most people realize. Because while maltitol is legally approved and technically “safe,” its effect on your insulin response can quietly sabotage your metabolic goals.
This article breaks down the real science behind maltitol, what EFSA actually says, and why a new generation of Germans with diabetes are relying on one simple tool: Food Scan Genius, the leading keto insulin spiker app.
The Hidden Problem: Maltitol, Insulin, and the Keto Trap
Maltitol is everywhere in Germany—especially in “zuckerfrei” products at DM Drogerie and low-carb snacks at Edeka. On labels, it appears as E 965, a sugar alcohol approved across the EU.
According to the European Food Safety Authority (EFSA), maltitol is considered safe for human consumption at accepted daily intake levels. It’s non-carcinogenic, non-genotoxic, and doesn’t cause birth defects at normal doses.
So what’s the issue?
Insulin.
Unlike erythritol, maltitol has a moderate glycemic index. That means it does raise blood glucose and insulin—just more slowly than sugar. For someone without diabetes, that may be irrelevant. For a Type 2 diabetic on keto, it can be the difference between metabolic control and frustration.
Peer-reviewed research confirms maltitol causes a measurable glucose response, especially when consumed repeatedly throughout the day (source). This matters because keto isn’t just about carbs—it’s about keeping insulin low.
And here’s the kicker: EU labeling rules do not require manufacturers to clearly state insulin impact. Traffic Light systems focus on sugar and calories—not insulin response.
So you think you’re compliant. Your pancreas disagrees.
What EFSA Doesn’t Warn You About (But Your Body Feels)
EFSA acknowledges that maltitol can cause gastrointestinal symptoms—bloating, gas, osmotic diarrhea—at high doses (around 90 g/day). At moderate doses (40 g), mild discomfort is possible (source).
But as a diabetic, the more subtle issue is cumulative insulin stimulation.
Snack here. Protein bar there. “Sugar-free” gum. By evening, your insulin has been nudged repeatedly—without you ever touching sugar.
This is why many German diabetologists caution against frequent maltitol intake on keto, even though it’s legally approved.
EFSA is currently conducting a re-evaluation of maltitol (E 965), focusing on additional genotoxicity data (official EFSA notice). While no major risks have been identified, this reassessment highlights how much is still evolving.
Regulation moves slowly. Insulin reacts instantly.
The Solution: Why Diabetic Germans Are Switching to Food Scan Genius
This is where Food Scan Genius changes the game.
Instead of guessing, calculating net carbs manually, or trusting front-of-pack claims, the app lets you scan any product at Edeka or DM and instantly see whether it fits your insulin goals.
Why Type 2 diabetics in Germany love it:
- You add maltitol to your personal “avoid or limit” list
- The app flags products containing E 965 instantly
- It evaluates compatibility with keto + insulin control, not just calories
- Built with EU ingredient databases and E-number recognition
This isn’t a generic calorie counter. It’s a keto insulin spiker app designed for people who need precision—not marketing promises.
When you’re managing Type 2 diabetes, peace of mind is metabolic medicine.

Real Story: A German Type 2 Diabetic Speaks
“I’ve had Type 2 diabetes for 11 years and switched to keto to reduce medication. I kept stalling—until I realized maltitol was in half my ‘safe’ snacks from DM. Food Scan Genius showed me exactly what was spiking my insulin. My glucose readings improved within weeks.”

Frequently Asked Questions
Is maltitol safe for Type 2 diabetics on keto?
Maltitol is approved as safe by EFSA, but it does raise blood glucose and insulin. For strict keto and insulin control, it should be limited or avoided.
Does maltitol spike insulin?
Yes. Maltitol has a moderate glycemic index and causes a measurable insulin response, especially with repeated intake (source).
Why is maltitol allowed in “sugar-free” products in Germany?
EU regulations classify maltitol (E 965) as a sugar alcohol, not sugar. This allows “zuckerfrei” claims despite insulin effects.
Is maltitol dangerous according to EFSA?
No. EFSA considers maltitol safe at normal intake levels, with gastrointestinal symptoms only at very high doses and no cancer risk (EFSA).
How does Food Scan Genius help with keto and insulin control?
It flags insulin-spiking ingredients like maltitol based on your personal dietary profile, helping you shop confidently at Edeka and DM.
