Insurance companies use underwriting to assess your health risks and set your premium rates. Your weight plays a major role in this evaluation alongside other health factors like blood pressure and medical history. Carrying extra weight typically increases your life insurance costs because insurers link higher BMI to health conditions like heart disease and diabetes.
If you're overweight, shop with insurers that specialize in higher-risk applicants rather than sticking with traditional carriers. Each insurer sets different BMI limits and weight requirements, so understanding these thresholds helps you find coverage that fits your situation.
