Insulin helps the body use and store glucose. Insulin resistance means that some tissues respond less effectively to it, so the pancreas may need to produce more insulin. It is not simply a “broken metabolism”, and it cannot be diagnosed from how tired or hungry you feel after a meal.
Symptoms are not a home test
Insulin resistance and prediabetes often have no clear symptoms. Weight change, a larger waist or cravings are not enough to establish a diagnosis. Some skin changes can be associated with insulin resistance, but they also need proper assessment rather than an online checklist.
What to discuss with a clinician
Ask about your personal risk factors and whether blood-glucose testing is appropriate. Bring a medication list and relevant family history. A food log can help describe your routine, but an app cannot replace the examination or laboratory tests.
Choose a sustainable next step
Regular physical activity, suitable nutrition and weight management where appropriate can form part of care. You do not have to eliminate all carbohydrates or start fasting to take a useful step. For example, plan a regular meal or a manageable walk. If you take glucose-lowering medication, discuss major changes to meal timing with your care team.
