Since discovering that I have Type 2 diabetes almost a year ago, my eating style has changed drastically. No more skillet meals. No more pasta. Simply put, diabetics are carb-intolerant and I eat very few carbs each day — and those that I do are slow-acting.

That means that I eat far more “plain” meats, cheese and eggs. But when I say “plain” meats, what I really mean is that they aren’t mixed with other ingredients, not that they don’t have tons of flavor!

This Spicy Grilled Pork Tenderloin is naturally very low carb, easy to make and absolutely delicious. Add in the fact that it keeps heat out of the boat or kitchen by grilling and lets the cook be part of the pre-dinner socializing, and it’s a real winner.

My low carb way of eating is even more restrictive than a keto diet, so this recipe is also good for those doing keto. Plus it’s gluten-free and dairy-free.

The only somewhat unusual ingredient is ground jalapeno. You can find it in the spice aisle in many Mexican groceries, in some general supermarkets, and on Amazon:


However, if you can’t find it, you can substitute additional cayenne pepper. It’s still a great rub!

P.S. Since I get questions every time I mention grilling, I’m still loving my new Magma grill for the boat — use it at least five nights a week! Read my full review here, or see it on Amazon.
