Doctors often give ineffective weight loss advice to people with obesity

In a study from the University of Oxford, scientists found that when doctors tell patients living with obesity to lose weight, the guidance they give is generally vague, superficial, and commonly not supported by scientific evidence.

Obesity is a chronic and relapsing condition, but physicians often lack guidance on which information is helpful for patients who would like to lose weight.

As a result, the information patients receive can be hard to use and implement. Bad experiences are regularly reported by patients, who often see these conversations about weight as difficult.

In the study, the researchers analyzed 159 audio recordings of consultations between general practitioners and patients living with obesity collected from the United Kingdom between 2013 and 2014.

The team found that weight loss advice from doctors to patients with obesity rarely included effective methods, and mostly consisted of telling patients merely to eat less and be more physically active.

The advice was mostly generic and rarely tailored to patients’ existing knowledge and behaviors, such as which strategies they had tried to lose weight before.

The advice was mostly (97% of the time in analyzed consultations) abstract or general.

The team found superficial guidance, such as one doctor telling a patient to just “change their lifestyle a bit” was common.

Doctors gave patients information on how to carry out their advice in only 20% of the consultations. They mostly offered weight loss guidance without any detail about how to follow it.

Doctors frequently (76% of the time in the consultations) told patients to get help somewhere else for support in weight loss, often suggesting that they return for another consultation at their surgery.

The analysis showed that when doctors did offer specific information, it was often scientifically unsupported and unlikely to result in actual weight loss.

The notion that small changes in behavior (“take the stairs more often”) can have a large weight loss impact is a common myth and is even prevalent in scientific literature, but it isn’t supported by research.

Another common myth was that patients just needed the “right mindset” to lose weight.

This research showed that doctors need clear guidelines on how to talk opportunistically to patients living with obesity about weight loss.

If you care about weight loss, please read studies that hop extract could reduce belly fat in overweight people, and early time-restricted eating could help lose weight.

The study was conducted by Madeleine Tremblett et al and published in Family Practice.
