How we research and review — Weight Loss Over 40 Tips

Every number on this site links to the study or official page it comes from, and every program review says how it was made. This page explains the checks behind that, step by step.

By the Weight Loss Over 40 Tips editorial team · Updated September 30, 2026

Where our facts come from

Public-health agencies: the CDC and its National Center for Health Statistics, the NIH, the Office on Women’s Health, and the official US Dietary Guidelines.
Peer-reviewed studies, which we find and check on PubMed. We link to the study itself, not to a news story about it.
Program facts and prices come from each program’s own official pages, and we write down the date we checked them.

If a primary source is silent on something, we say “not listed” rather than guess.

How we read a study

We say how big a study was and who took part. A trial of 10 young men is not a trial of women over 40, and we say so.
We separate what a study found from what a seller claims. Claims from a program’s own sales page are labelled as the seller’s claims.
We avoid promises. We write “can help”, “is linked to” or “in one trial”, never “melts fat” or “guaranteed”.

Two dates on every article

Updated is the last time we changed the content.
Verified against primary sources is the last time we checked the article’s facts and numbers against their sources. It only changes after a real check.

How we check an article

When we review an existing article, we go through every number and every factual claim, look each one up in its source, and rank what we find: wrong, unsourced, or overstated. Wrong numbers are corrected, unsourced numbers get a source or are removed, and overstated claims are toned down. Significant corrections are noted at the end of the article with the date.

How we review programs

Unless a review says otherwise, it is based on the program’s published materials, its pricing and independent research — not on personal testing. When we have not tried a program, the review says so.
What we look at: what the program actually asks you to do; the evidence behind its approach; the full price, including what renews; how well it fits women in perimenopause and menopause; and who it is not for.
Prices are taken from the official US pricing page and dated (“checked September 2026”). Prices change often; the date tells you how fresh ours is.
Ratings out of 5 are our editorial judgement from the points above. They are never for sale.
Discount codes come directly from the brand or its affiliate program; we never publish codes we found elsewhere.

How our calculators work

Our calorie and TDEE calculators use the Mifflin–St Jeor equation; the BMI calculator uses the standard BMI formula. Each calculator page explains its formula. The results are estimates, not prescriptions.

What we don’t do

No invented testimonials, reader stories or before-and-after photos.
No paid placements and no sponsored rankings.
Photos of people are stock photos or illustrations, captioned as such, and never shown next to a result or a claim about body size.
