According to its website, Wondr Health is an online counseling program that teaches a person how and when to eat. The company says that its program does not involve:

  • counting points or calories
  • limiting food selections
  • dieting

Instead, Wondr Health describes itself as a “trusted solution” for a range of clients. For instance, it aims to help businesses encourage their employees to engage in behaviors that improve their health. It also aims to help doctors provide support to patients who hope to lose weight.

This program may be suitable for people with excess body weight and those looking to maintain a moderate weight.

Although the company does not currently hold accreditation with the Better Business Bureau (BBB), the organization gives Wondr Health an A+ grade. There are no customer reviews on the BBB website, but the company has apparently closed two complaints in the last 3 years.

One of these complaints mentions problems canceling the subscription, with the customer saying that it was difficult to get in contact with the company after it continued billing their insurance after the cancellation.

The other individual who complained states that they received text messages from third parties after signing up for the company’s services. The company replied that it does not sell personal details to others.

Wondr Health does not have any Trustpilot reviews.

However, reviews on the App Store and Google Play are mostly positive, with people describing the service as efficient and convenient. The less positive reviews mention occasional technical glitches within the app.

Wondr Health offers video lessons and other online learning tools. The goal is to help a person reach or maintain a moderate weight.

Employers or clinics tend to offer the program. A person may, for example, be able to access it using their employee login information. Alternatively, a person can sign up as an individual on the company’s website.

The videos and other materials are available on desktops, mobile devices, and tablets. A person has unlimited access to the materials for the duration of their subscription.

Each of the company’s programs lasts 1 year, and the company claims that users notice benefits within that period.

A person must sign up to Wondr Health through its website.

People can choose to pay a monthly fee of $50 or a yearly fee of $450. Once a person has chosen their subscription, they will receive a confirmation email and a welcome kit through the post. Then, they must download the app onto their smart device to access classes and resources.

Wondr Health also offers access through some employers. People can check their eligibility through the company’s website.

Wondr Health aims to encourage weight loss through mindful eating. Its website cites several findings from a 2015 study, including:

  • female and male participants in the program lost an average of 9.4 pounds (lb) and 13.2 lb, respectively, in the first 10 weeks
  • 55% of the participants reversed their diabetes risk
  • about 50% of the participants with metabolic syndrome at baseline did not have it after 10 weeks

The study included 3,880 participants from 93 companies. The researchers concluded that the program had successfully changed core behaviors to reduce weight and reverse metabolic syndrome.

However, it is crucial to note that one of the two researchers behind this peer-reviewed study is Wondr Health’s chief medical officer.

Preventing obesity or overweight can have significant health benefits. According to the American Heart Association (AHA), some benefits of maintaining a moderate weight include:

Wondr Health claims that its program also helps people prevent or reverse metabolic syndrome — a collection of risk factors for conditions such as heart disease, diabetes, and stroke.

According to the National Heart, Lung, and Blood Institute, a person must have at least three of the following five factors for a diagnosis of metabolic syndrome:

To reap the potential benefits of Wondr Health, a person must use the learning materials regularly. However, various factors, such as restricted time, may prevent this.

The AHA recommends that people looking to reach or maintain a moderate weight take certain steps. These include:

  • managing portion sizes
  • tracking eating habits using a journal or app
  • setting realistic goals to avoid disappointment or frustration
  • getting at least 150 minutes of moderate physical activity a week
  • eating a nutritious, varied, and well-balanced diet

The United Kingdom’s National Health Service (NHS) states that a person should consult a doctor if they have tried to lose weight but have not been successful.

Healthcare professionals can help people identify the reasons why they are unable to lose weight and set a sustainable plan that may help a person reach their weight goals. They can also check a person for any health conditions.

In some cases, doctors may prescribe medication to help people lose weight. They may also recommend weight loss surgery if a person has obesity that is severe or occurs alongside risk factors such as type 2 diabetes.
