Evidence & Editorial Policy

Keto claims can move faster than the evidence. This policy explains how 247-Keto checks the underlying research, communicates uncertainty, and records meaningful changes.

Source hierarchy

Health and nutrition claims are checked against the most current evidence available when a page is updated. The preferred sources are:

  1. Primary human research, especially randomized controlled trials and well-designed prospective studies.
  2. Systematic reviews and meta-analyses that show their search, selection, and quality-assessment methods.
  3. Current clinical guidelines and consensus statements from relevant professional organizations.
  4. Official reference data, such as nutrient records from USDA FoodData Central.

Animal, cell, mechanistic, preprint, and case-report evidence may explain a hypothesis, but it is labeled and is not used to claim a proven benefit in people. Commercial pages and general health explainers may help locate a topic; they are not the evidentiary basis for a medical conclusion.

Evidence is not the same as interpretation

  • Claims are traced to the cited paper, guideline, or data record, not copied from another article's summary.
  • Population, intervention, comparator, duration, outcomes, and major limitations are checked before a result is generalized.
  • Biomarker changes are not described as proof of fewer heart attacks, longer life, disease reversal, or another clinical outcome unless a study measured that outcome.
  • Research on a broadly low-carbohydrate diet is not automatically described as research on a ketogenic diet.
  • Conflicting results, low certainty, short follow-up, attrition, and relevant funding or author conflicts are included when they change how a finding should be read.

Writing and citation standard

Articles use direct links to research papers or authoritative records wherever possible. Researchers and clinicians may be named when their work or expert role is relevant; publishing staff are not used as a substitute for evidence. Language is revised to remove hype, formulaic filler, false certainty, and promotional framing while preserving verifiable facts and useful context.

United States food-label scope

247-Keto is written for an English-language United States audience. When a page explains a packaged-food label, serving size, or a nutrient field, it uses the U.S. FDA Nutrition Facts framework and identifies the source record or current package that controls the comparison. Food-database records use USDA FoodData Central as a composition reference; they are not a substitute for the package in a shopper's hand.

USDA Food Safety and Inspection Service rules can govern labels for meat, poultry, and certain egg products. Health-related promotional claims need scientific support and must not mislead under U.S. truth-in-advertising principles. This educational policy is not product-label compliance or legal advice. See the FTC's Health Products Compliance Guidance for its framework on substantiation.

“Net carbs” is an editorial calculation, not a required FDA Nutrition Facts field. Unless a page says otherwise, this site calculates it as total carbohydrate minus dietary fiber, capped at zero. It does not automatically deduct sugar alcohols, allulose, or another ingredient because labeling treatment and the exact product can differ. Readers outside the United States should not transfer U.S. label arithmetic to another jurisdiction without checking the local label rules.

See the FDA's guide to using the Nutrition Facts label for the current U.S. consumer-label framework.

Medical disclaimer

Content is for general educational purposes and is not medical advice, diagnosis, or treatment. Individual needs vary. Consult a qualified healthcare professional before starting keto or changing diet, exercise, or medication, especially during pregnancy or breastfeeding, when taking medication, or with diabetes or kidney, liver, or heart disease. A publication date, citation list, tool result, or evidence label does not make content individualized medical advice.

Updates, article histories, and corrections

Newer is not always stronger, so new studies are read in the context of the full evidence base. Each article history records first publication and substantive evidence or safety updates. A displayed review date is changed only when the page itself has been checked; automated formatting does not count as a scientific review.

Confirmed factual, calculation, citation, safety, and broken-link errors are corrected in the page and recorded when they materially affect the conclusion. Silent changes are limited to spelling, formatting, and other non-substantive fixes.

Brands, practitioners, and commercial relationships

Directory inclusion is factual and is not an endorsement, ranking, medical referral, or product review. Brand claims are checked at product and serving level; practitioner credentials, jurisdiction, and availability are tied to official current sources. The site currently has no paid placements or affiliate links. If that changes, a page-level disclosure will appear before any commercial link and the relationship will not determine inclusion.
