A practical guide to low-carb living.
Most of what you need to know fits in this one page. Read it once, refer back when something gets noisy, and let your glucose meter handle the rest.
Why fewer carbs?
Carbohydrates are the food group that most directly drives blood glucose. Protein nudges it. Fat barely moves it. So if your aim is calmer, more predictable numbers — and far smaller margins for error — the simplest lever is the amount of carbohydrate you eat at a given meal.
That doesn't mean zero. It means a small, consistent amount, eaten at consistent times, paired with enough protein and vegetables that you finish the meal genuinely satisfied.
Targets to aim for
These are starting points, not prescriptions. Work with your clinician to choose targets that match your situation, medications, and history.
- Carbohydrate: a modest, consistent amount per meal — for many people roughly 6g at breakfast, 12g at lunch, 12g at dinner.
- Fasting glucose: aim for the lower end of the range your clinician has set with you.
- Post-meal glucose (90 minutes): ideally back near your pre-meal reading. A small rise is fine; a big swing is information worth acting on.
- Hydration & salt: low-carb eating tends to flush sodium. A little extra salt — within your clinician's guidance — keeps you feeling steady.
What to eat (and what to set aside)
Use this as a starting palette. After a few weeks of testing, you'll have a personalized list that's both shorter and more interesting than any printed guide.
Eat freely
- Eggs in every form
- Fish & shellfish
- Poultry, beef, lamb, pork
- Leafy greens — spinach, arugula, chard, kale
- Cruciferous vegetables — broccoli, cauliflower, cabbage
- Zucchini, asparagus, green beans, peppers
- Avocado, olives, olive oil, butter, ghee
- Hard cheeses, full-fat plain yogurt, heavy cream
- Nuts & seeds in modest amounts
- Herbs, vinegars, mustards, hot sauce
Limit or skip
- Bread, pasta, rice, oats, cereal, crackers
- Potatoes, sweet potatoes, corn, peas
- Most legumes (beans, lentils, chickpeas)
- Sugar, honey, syrups, agave, “raw” sugar
- Fruit juice and smoothies
- Most fruit — small amounts of berries are a fair exception
- Sweetened or flavored yogurts and milks
- Beer, sweet wines, sugary cocktails
- “Low-fat” foods where fat has been swapped for sugar
Building a plate
A useful template for nearly any meal:
- One palm of protein. Eggs, fish, meat, tofu — your call.
- Two cupped hands of non-starchy vegetables. Cooked or raw. Dress them with real fat.
- A thumb or two of fat. Olive oil, butter, avocado, cheese — enough to make it taste like food, not a regimen.
- A small carb — or none. A spoonful of berries, a square of dark chocolate, or nothing at all if you're not interested.
How to read your meter
The meter (or continuous glucose monitor) is the entire point. Without it you're guessing; with it, the diet becomes a feedback loop.
- Test before the meal. Note the number.
- Eat the meal. Record what you ate — at least roughly.
- Test 90 minutes after the first bite. Compare.
- Look for the pattern, not the point. One reading is weather; a week of readings is climate.
If a meal pushes you significantly above your pre-meal number, change one thing for next time — smaller carb portion, slower eating, a walk after — and test again. Two or three iterations usually settle it.
A blood glucose meter is not a verdict. It's a conversation you can have with your own body, in numbers.
A gentle first week
- Day 1–2: Don't change anything. Just test before and 90 minutes after each meal. Write the numbers down.
- Day 3: Swap breakfast for something with under 10 grams of carbs. Eggs are the path of least resistance.
- Day 4–5: Apply the plate template to dinner. Replace rice or potato with a second vegetable.
- Day 6: Try the same dinner again. Notice how steady the meter reads when nothing surprises it.
- Day 7: Look at your week. The next week is a refinement of this one — not a reinvention.
Common questions
Is this safe for type 1 diabetes?
Many people with type 1 eat this way under close clinician supervision, and the smaller carb numbers tend to make insulin dosing more forgiving. The flip side: insulin doses almost always need to be adjusted downward, sometimes substantially. Don't change diet and dose in the same week without a clinician's input.
Will I miss bread, pasta, and dessert?
For a week or two — sometimes, yes. Then less. Most people land somewhere honest: they don't crave the old default, but they enjoy a thoughtful exception now and then. The point isn't purity; it's predictability.
What about exercise?
Movement is a powerful glucose lever — a 15-minute walk after a meal often blunts the rise more than any food choice. We're fans of walking, lifting, gardening, dancing — whatever you'll do twice this week.
Do I have to count anything?
Count carbs at meals, at least at first — you can't manage what you don't measure. After a few weeks, most people stop counting on familiar meals and only do it for new dishes.
Is this expensive?
It can be, but it doesn't have to be. Eggs, frozen vegetables, canned fish, ground meat, and seasonal produce are inexpensive and form the backbone of most weeks.
