🔮

Kidney & Liver

Keto puts extra protein and fat through both organs. Existing damage changes the calculation.

Have you been told you have chronic kidney disease, reduced kidney function, or are on dialysis?

Have you ever been hospitalized or treated for pancreatitis?

Has your gallbladder been removed?

💊

Diabetes & Blood Sugar

Keto can drop blood sugar fast. Some diabetes medications make that drop dangerous.

Do you have Type 1 diabetes?

Do you take Jardiance, Farxiga, Invokana, Steglatro, or another SGLT2 inhibitor?

Are you on insulin, glipizide, glyburide, or glimepiride for diabetes?

❤️

Heart & Blood Pressure

Keto changes fluid balance, electrolytes, and lipid profiles — all of which interact with cardiac medications.

Do you take warfarin (Coumadin) for blood thinning?

Do you take medication for high blood pressure?

Do you have heart failure, or have you had a heart attack, stroke, or stent placement in the past year?

🧮

Other Considerations

Three more situations where keto needs adjustment or a different approach entirely.

Have you had gout flare-ups in the past?

Do you have a personal history of anorexia, bulimia, or binge eating?

Are you currently underweight, frail, or losing weight without trying?

Why Keto Is Different After 65

The ketogenic diet has earned a real place in modern medicine for a few specific uses — pediatric epilepsy, some cases of Type 2 diabetes reversal, and possibly slowing certain cancers. But for older adults, the picture is more complicated.

By age 65, most people are taking at least one prescription that interacts with a major dietary shift. Blood pressure meds, blood thinners, diabetes drugs, and statins all change behavior when carbs drop and fats rise. Add the higher rates of kidney disease, gallbladder removal, and pancreatitis history in older adults — and the “just try it for two weeks” advice that works for a 35-year-old becomes risky.

This quiz is not medical advice. It’s a screening tool that flags the conditions and medications most likely to make keto unsafe for someone over 65, based on guidance from the Academy of Nutrition and Dietetics, the American Diabetes Association, and peer-reviewed reviews of keto in older populations.

Who should take this quiz?

  • Anyone 65 or older considering a low-carb or ketogenic diet
  • Adult children whose parent is asking about keto for weight loss or blood sugar
  • Caregivers wanting a quick screen before recommending a diet change
