Blood sugar
What should I eat for insulin resistance?
Start with a plate built from vegetables, fiber-rich carbohydrate foods and protein, and swap sweetened drinks for water. A registered dietitian fits those basics to your labs and routine, while your doctor reads your blood tests and manages any medicines.

What is insulin resistance?
Insulin resistance means your body does not respond to insulin the way it should. NIDDK says that can raise blood sugar over time and contribute to weight gain.
Most people feel no symptoms. It often shows up as part of prediabetes or with conditions such as PCOS or sleep apnea. Your doctor decides which blood tests you need.
Because there is little to feel, it is often found through routine blood work. That makes your lab results a useful starting point for any eating plan, and a good reason to bring them to your dietitian.
What should your plate look like?
NIDDK describes a simple plate: half nonstarchy vegetables, a quarter high-fiber carbohydrate foods such as whole grains or fruit, and a quarter protein. This can help manage blood sugar without counting carbohydrates.
- Fill half your plate with vegetables like salad greens, broccoli, peppers or green beans.
- Choose whole grains, beans or fruit for the carbohydrate quarter.
- Add a protein food you enjoy, such as fish, eggs, tofu, chicken or lentils.
- Drink water instead of sweetened beverages, as NIDDK advises.
- Notice portions. Smaller portions are a common starting point.
Does anything besides food matter?
Yes. NIDDK frames healthy eating as one part of a lifestyle that also includes being active, managing weight and getting enough sleep.
A dietitian starts with food, but will ask about your sleep, stress, activity and medicines too. Those can change how your body handles the same meal, and some of them are for your doctor to address. The plan stays small and specific so you can follow it on a busy week.
When should you see your doctor first?
See your doctor if you have never been tested, or if you notice constant thirst, frequent urination, blurred vision or unusual tiredness. Also ask before changing your eating if you take any diabetes medicine.
- You have risk factors such as family history, extra weight or PCOS and have not had a blood sugar test.
- A recent A1c in the diabetes range, 6.5 or above, means your doctor should guide your next steps.
- You take a medicine that affects blood sugar. Your prescriber should guide any change.
How do you start?
A first visit ($140, self-pay) works best with recent labs and your medicine list in hand.
For regular follow-up, see the Personalized Care Plan.
What patients say about this kind of care
One patient working on insulin and weight valued instructions that were actionable, clear and simple.
“She gave me actionable, clear, simple instructions.”
Insulin resistance is a long-game topic, so the approach matters more than a quick fix.
“She's in nutrition and weight loss for the person's health and vitality — not just a quick fix.”
A plan works better when it starts by hearing every concern and then focuses on the main points.
“She listened to all my concerns, then discussed the main points to improve my overall health that would help with weight loss.”

Frequently asked questions
Is there a specific insulin resistance diet?
There is no single diet. NIDDK describes healthy foods and drinks as part of a broader lifestyle. Your dietitian shapes a plan around your labs, food preferences and medicines.
Do I have to avoid all carbohydrates?
Usually not. Most plans choose high-fiber carbohydrate foods and watch portions rather than removing them.
Is there a test for insulin resistance?
There is no routine test for insulin resistance itself. Your doctor looks at blood sugar, A1c and related results and decides what they mean. The dietitian builds the eating plan.
Should I ask my doctor about supplements?
Ask your doctor, pharmacist or dietitian before starting any supplement, especially if you take medicine for blood sugar.
