Methodology

How we score gear

This page exists so you can judge our work the way we judge products. It covers what the LeanScore is made of, what we look at in each department, the language we will and won't use about a product, and — first, because it matters most — what we do not do.

1. We do not test products hands-on

We do not test products hands-on. We compare labels, specifications and owner reviews. There is no LeanFed lab, no test kitchen, no panel. Nobody here drank forty protein shakes and ranked them. When you read that a powder mixes cleanly or a container leaks, that is a pattern across many owner reports, not our experience — and we say which it is.

We also do not invent reviewers. Every guide is written and edited under the brand name, LeanFed Editors. There is no fictional dietitian, no stock-photo “expert”, and no clinician's name used as decoration.

2. What we will and won't claim about a product

LeanFed is not medical advice, and nothing sold through this site treats, prevents, cures or reverses anything. The strongest claim we will make for a product is that it may help with convenience, comfort, intake or tracking. Concretely:

Phrases you will never find here: “natural Ozempic”, “GLP-1 booster”, “fat burner”, “detox”, “must-take stack”. If a product is marketed that way, that is a mark against it, not a headline.

3. Red flags come before products

On any page that touches a symptom, the reasons to contact a clinician are placed aboveanything you could buy. Severe or persistent abdominal pain, vomiting you can't stay ahead of, signs of dehydration, allergic symptoms, a sudden change in vision, or symptoms that suggest a pancreas or gallbladder problem are not shopping problems. Dose, timing, side-effect severity and whether to continue are conversations with your prescriber. We never cover them.

4. The LeanScore, in full

Every pick carries a LeanScore from 0 to 100. It is deterministic, computed identically in every category, and blends exactly two published dimensions — there is no hidden weighting and no editorial thumb on the scale:

That is the whole formula: LeanScore = 0.72 × owner satisfaction + 0.28 × value. A score is not a nutrition rating, not a safety rating, and not a judgement about whether something suits your body.

Rank order follows the LeanScore. When we place a product above a higher-scoring one, the page says so and gives the reason in an editor's note — that is the only permitted override, and a build check fails if a rank-1 pick carries neither the top score nor a written justification.

We also hold products back. When a listing is real and well-liked but does not belong in a list ranked on that category's stated criterion, it is removed from the ranking and shown instead at the bottom of the page with the reason written out, so the omission is visible rather than silent.

5. What we look at, department by department

Specification cells come from manufacturer data and label text. When a value isn't published, the cell stays empty rather than getting a plausible guess.

6. Live listings, current prices

Every product we link is verified as a real, live listing, and prices and availability are re-pulled on a recurring cycle — last refreshed Aug 22, 2026. When we can't confirm a current price we stop quoting one rather than showing you a stale number, and a listing with a positive dead signal loses its link entirely. Prices move; the listing is always the authority.

7. Money

As an Amazon Associate, LeanFed earns from qualifying purchases. That commission costs you nothing extra and has no input into the formula above — the ranking is arithmetic on published ratings and prices. Our most common recommendation at the earliest stage is to buy nothing at all. See the full affiliate disclosure.

8. Sources

Health and medication facts come from primary sources — FDA labels via DailyMed, NIH and NIDDK, the NIH Office of Dietary Supplements, CDC, USDA FoodData Central, and peer-reviewed literature. We do not repeat precise-sounding statistics from other blogs. More detail on how we research.
