Introduction: Why Keto Works—Even in a Humble Kitchen
When my wife Sarah and I first heard about the ketogenic diet, we were skeptical. Could a diet that limits rice, beans, and bananas—three Dominican staples—really fit our lifestyle as missionaries living on a tight budget in the Caribbean heat?
The answer surprised us. Not only did keto help balance my blood sugar (I’m diabetic), but it also simplified our meals and reduced cravings. The challenge, of course, was figuring out what we could actually eat with limited access to imported ingredients.
Our propane stove and tiny fridge became our allies, and we built a keto-friendly kitchen from scratch—using local foods, simple swaps, and a little creativity inspired by my late Grammie Shirley, who believed every meal was a chance to share love.
This post is a culmination of everything we’ve learned: a realistic, flexible, and genuinely helpful Keto Can and Can’t Eat List designed for normal people—whether you’re in a small-town apartment or a Dominican village with the power flickering off again.
Understanding the Keto Diet (and Why This List Matters)
At its core, the ketogenic diet trains your body to burn fat for energy instead of glucose. This happens through ketosis, a metabolic state triggered when your carb intake is drastically reduced (usually below 20–50 grams daily).
When you stay in ketosis, your body burns fat more efficiently, energy levels stabilize, and many people notice improved focus and reduced hunger. But reaching and staying in ketosis requires one thing above all: clarity about what to eat—and what not to.
The Keto Macro Breakdown
- 70–75% healthy fats (your main energy source)
- 20–25% moderate protein (to support muscles and metabolism)
- 5–10% low carbohydrates (mostly from non-starchy vegetables)
When I first calculated my macros, I used a free online tracker—but quickly realized that tropical life meant I had to estimate. Fresh foods here don’t always come with labels! Over time, I learned to eat intuitively: lots of greens, enough protein, and just a handful of nuts when needed.
And that’s what I love about keto—it’s flexible once you understand the framework.
What You CAN Eat on Keto (The Delicious, Real-World List)
Keto is often described as restrictive, but I’ve found it to be the opposite. Once you stop fearing fat and start embracing real food, your kitchen comes alive again.
Healthy Fats: Your Energy Source
- Avocados (we have them fresh year-round!)
- Coconut oil and MCT oil
- Olive oil
- Butter or ghee
- Animal fats (lard, tallow—old-fashioned but effective)
Here in the DR, I use coconut oil for everything—sautéing veggies, frying eggs, even stirring into coffee. When the power’s out, coconut oil doesn’t spoil easily, which is a huge bonus.
Proteins: The Building Blocks
- Chicken, beef, pork, goat, and turkey
- Fish and seafood (snapper, tilapia, shrimp)
- Eggs (our #1 budget protein)
Sarah laughs because I could eat eggs three times a day and not get bored. Scrambled, fried, or baked into cheesy frittatas—they’re keto gold.
Low-Carb Vegetables
- Spinach, kale, lettuce, cabbage
- Broccoli, cauliflower, zucchini, cucumbers
- Bell peppers, celery, eggplant, and green beans
We make a cauliflower “rice” dish every week—grated, fried in coconut oil, and seasoned with garlic and herbs. Even the kids eat it happily when we call it “island rice.”
Dairy (If You Tolerate It)
-
Cheese, butter, cream, Greek yogurt (unsweetened)
Our local cheese is firm and salty—perfect for grating over keto casseroles or melting into an omelet.
Nuts, Seeds & Keto-Friendly Fruits
- Almonds, walnuts, chia seeds, flaxseeds, pecans
- Keto fruits (in moderation): strawberries, blackberries, avocados, coconuts
Fresh coconut water is too sugary for strict keto, but the meat is fantastic for fat bombs or smoothies.
Beverages
- Water, sparkling water, unsweetened coffee, herbal tea
- Homemade electrolyte drinks (water, salt, lemon, a pinch of potassium salt)
Our mornings usually start with coffee blended with coconut oil—a tropical twist on “bulletproof coffee.”
What You CAN’T Eat on Keto (and How to Spot Hidden Carbs)
Let’s face it—carbs are sneaky. Even if you avoid bread and sugar, they creep into sauces, condiments, and “diet” foods.
High-Carb Foods to Avoid
- Grains: rice, pasta, oats, corn, quinoa, cereal
- Starchy veggies: potatoes, plantains, sweet potatoes, yucca
- Fruits high in sugar: mango, banana, pineapple, papaya
- Legumes: beans, lentils, peas, chickpeas
- Sugary foods: candy, pastries, soda, sweetened yogurts
I can’t count how many times I’ve grabbed tomato sauce here, only to discover sugar as the second ingredient! Now I check every label—or just make my own sauce with olive oil, garlic, and fresh tomatoes.
Avoid These “Fake Keto” Traps
- Processed bars or “keto cookies” (often loaded with sugar alcohols like maltitol)
- Low-fat products (they often replace fat with carbs)
- “Net carb” gimmicks—total carbs still matter
Grammie Shirley’s advice still rings in my ears: “If it’s made in a factory, it’s probably not good for your body.” Wise woman.
Smart Keto Substitutions (When Ingredients Are Limited)
Living in a small town, I’ve had to get creative. Here are tried-and-true keto swaps that actually work:
Traditional Food |
Keto Substitute |
Why It Works |
---|---|---|
Rice |
Cauliflower rice |
Light, low-carb, and quick to make. |
Pasta |
Zucchini noodles, spaghetti squash |
Great texture and easy to flavor. |
Bread |
Almond or coconut flour bread |
Satisfies cravings without the carbs. |
Sugar |
Stevia, erythritol, or monk fruit |
Sweet taste, no blood sugar spike. |
Milk |
Coconut or almond milk |
Shelf-stable and versatile. |
Beans |
Mushrooms or diced eggplant |
Similar texture in soups and stews. |
One rainy afternoon, our power went out mid-cooking. I finished dinner on the propane stove with candlelight—cauliflower rice, pork chops, and sautéed greens. It turned out so good that Sarah said, “Maybe we should lose power more often!”
Keto on a Budget (and in Real Life)
You don’t need imported supplements or gourmet ingredients to succeed on keto. You just need consistency and creativity.
My Top Budget Keto Tips
- Buy in bulk: eggs, meat, cheese, and oil are cheaper that way.
- Use local produce: Dominican cabbage, zucchini, and peppers are affordable.
- Batch cook: crock pot meals like pulled pork or chicken thighs stretch over several days.
- Keep snacks simple: boiled eggs, nuts, cheese sticks, or cucumber slices.
- Plan leftovers: tonight’s roasted chicken becomes tomorrow’s salad or soup.
Cooking for ministry teams can be tricky—rice stretches further than meat—but I often make “dual” meals: keto-friendly meat and veggie base for me, rice or pasta added for others. Everyone’s happy, and no one feels left out.
