The 5 best products for type 2 diabetes.

Why body composition matters in diabetes: For diabetics, the number on a regular scale is far less important than visceral fat percentage — fat stored around your organs is the primary driver of insulin resistance. Only body composition monitors measure this.

Questions, answered.

How did HealthRankings choose these body composition monitors for diabetes & weight management?

Our editorial team independently researches, tests, and evaluates products using a weighted scoring methodology. We assess accuracy, ease of use, value for money, and category-specific criteria relevant to each condition. Every product is scored on a 10-point scale, and only the top 5 make our final list.

We buy every product at retail — no manufacturer samples — and our medical reviewers have no financial relationship with any brand we cover.

How often are these rankings updated?

We update our rankings at least once per quarter, and immediately when a significant new product launches or when we discover issues with a previously ranked product. Our current rankings were last verified in April 2026.

If a product is discontinued, recalled, or its price changes significantly, we update the listing within one business day.

Is the #1 pick always the best choice for everyone?

Not necessarily. Our #1 pick (Withings Body Comp) scored highest overall, but the best product for you depends on your specific needs, budget, and preferences. For example, if budget is your primary concern, a lower-ranked product with a better value score might be the better choice.

We recommend reading through all 5 reviews and paying attention to the "What to know" sections to find the best fit for your situation.

Are these products covered by insurance or HSA/FSA?

Many health monitoring devices and home testing kits qualify for HSA (Health Savings Account) and FSA (Flexible Spending Account) reimbursement. However, coverage varies by plan and product category. We recommend checking with your insurance provider or benefits administrator before purchasing.

Some products in our list may also be partially covered by Medicare or Medicaid depending on your diagnosis and prescription.

Can I return a product if it doesn't work for me?

Return policies vary by retailer and manufacturer. Most Amazon purchases can be returned within 30 days. Many manufacturers offer satisfaction guarantees ranging from 30 days to 1 year. Check the specific return policy before purchasing.

If a product is defective, most manufacturers will replace it under warranty regardless of the retailer's return window.

Should I consult my doctor before using these products?

Yes — we always recommend discussing new health monitoring devices or tests with your healthcare provider, especially if you have a diagnosed condition. Your doctor can help you understand your results, set appropriate monitoring schedules, and integrate home monitoring data into your overall treatment plan.

These products are designed to supplement — not replace — professional medical care.
