Our Weight-Loss Review Process

(The above photo is a selection of actual products we have purchased in the course of creating our reviews.)

Since we launched in 2009, we’ve reviewed more than 10,000 weight-loss products, programs and equipment.

Funding the creation of our reviews is not cheap. The operation of our website, including paying our writers and researchers, is supported by the sale of products such as Dietspotlight Burn and Pronabolin. The commercial connection between these products and Dietspotlight is made clear throughout the website. Though we do make money from sales of our product, our mission is to educate our visitors in a fair manner about health, dieting and nutrition.

In the course of our work, we’ve created a system of evaluation based on clinical research, user comments and our own expert opinion.

Though from time to time we tweak and improve our review process, the following is our overall framework:


Product details includes a clear list of ingredients and accurate labeling; information on where and how the product was manufactured or formulated; and comprehensive support for claims associated with the product.


The nature of the ingredients – and the purity and quantity of each ingredient – in a supplement is critical to revealing whether the product delivers on the claims made by the company.

To research ingredients, we access information produced by the National Library of Medicine and the National Institutes of Health, such as searches of MEDLINE/PubMed, databases that index medical research literature and ClinicalTrials.gov, the database of clinical research studies conducted at the National Institutes of Health and many other institutions worldwide.

We also use Google Scholar, WebMD, Wikipedia, Food and Drug Administration, Nutrition.gov and more. (See below for additional resources.)

Clinical studies follow a hierarchy in terms of the evidence and quality they provide. As a result, in our ingredient research we look for the “Gold Standard” of studies, which is randomized, double-blind, placebo-controlled (RDBPC) studies on human beings that ultimately support the product claims made by the company. Needless to say, the more RDBPC studies support an ingredient, the better.


Instead of focusing on the specific product formula, we look closely at the specific product ingredients – and amounts of each ingredient – to determine possible side effects.


We cover the history of the company and product. For example, has the company been rated by agencies such as the Better Business Bureau? If so, how many positive, negative and neutral reviews? How many customer complaints? What year was the company founded? Is information about the company – including contact information and executive biographies – easy to access?



Is the user experience in line with product claims? How do users rate their experiences? Our review of customer experience is not limited to good, bad or neutral. We examine all reviews and report accordingly.


Some companies offer customers a trial offer to give them a chance to see how they feel when taking a supplement.


What is the cost of the product? With supplements, what is the cost per serving? How does that cost compare to that of competitors?


If a customer doesn’t have the experience they expected with a product, is there a clear return/refund policy? What costs will the customer have if the product is returned?


We look at whether the company incorporates calorie awareness, accountability, food variety and exercise.


Though our reviewers make every effort to follow the above process, it should be noted that all views expressed here are purely our own.

Please note, our researchers deviate from this process from time to time depending upon the unique aspects of each product. For example, for the products whose reviews collectively account for much of our traffic, we purchase and take possession of that product to write a more in-depth review.
