The use of the Body Mass Index (BMI) in determining if an individual’s weight is healthy should be scrapped due to concerns it contributes to eating disorders, according to a report by MPs.
The Women and Equalities Committee warned the impact of the pandemic, both on eating disorder sufferers and those at a high risk of developing one, has been “devastating”.
Their inquiry into body image also branded the Government’s obesity strategy “dangerous” for those with negative body image, potentially triggering eating disorders in the people it is designed to help.

The report warns that BMI, used as a health risk indicator in individual patients who are then put on weight loss or weight gain programmes prompted by their score, contributes to issues such as eating disorders and poor mental health.
“We have been hugely saddened to hear of the number of people who have faced appearance and weight-based discrimination when accessing NHS services,” the report said.
“The use of BMI inspires weight stigma, contributes to eating disorders, and disrupts people’s body image and mental health.”
It recommended that Public Health England stops using BMI as a measure of individual health and instead focuses on a “Health at Every Size” approach.
This honours differences in factors such as age, ethnicity and gender, and prioritises healthy lifestyle choices over correcting weight, according to the report.
On the obesity strategy, the committee said that it was “at best ineffective and at worst perpetuating unhealthy behaviours” and called for the Government to commission an independent review into the evidence base for its policies.
It also urged the Government to immediately scrap plans for calorie labels on food in restaurants, cafes and takeaways, amid concerns it will contribute to growth in eating disorders and disordered eating.
MPs also called on the Government to bring forward legislation restricting or banning the use of altered images in adverts, over concerns this is contributing to poor body image.
Chair Caroline Nokes said: “Over the past 10 years, there has been a wealth of research and recommendations on how to tackle negative body image but Government action in this area is limited – we need to see urgent action.
“The pressure will intensify as gyms and beauty salons reopen on Monday,” the Conservative MP added.
“This may be exciting for some but it will be difficult for people who experience body image anxieties. It’s critical that Government action works towards improving body image.”
Tom Quinn, director of external affairs at the eating disorders charity Beat, said: “This past year has been particularly difficult for those affected by eating disorders, with Beat’s helpline alone delivering 100,000 support sessions and seeing a 302% increase in demand, and we believe further measures urgently need to be taken to protect those at risk.
“We welcome the committee’s call for an urgent review into eating disorder rates, and to ensure that there is sufficient support available for those affected.
The Government’s obesity strategy must be immediately reviewed, as it includes measures known to be dangerous to those unwell or vulnerable, such as listing calories on menusTom Quinn, Beat
“BMI should never be used as the sole factor in diagnosing eating disorders, or for determining who is ‘unwell enough’ to access treatment.
“This can lead to potentially dangerous delays, and can drive people deeper into eating disorders in order to be taken seriously.
“The Government’s obesity strategy must be immediately reviewed, as it includes measures known to be dangerous to those unwell or vulnerable, such as listing calories on menus.
“We believe that none of the measures that pose risks should be implemented until this review has taken place.
“We strongly support the call for increased, ring-fenced funding for eating disorder research, as they remain one of the most poorly understood mental illnesses.”
Dr Agnes Ayton, chair of the Faculty of Eating Disorders Psychiatry at the Royal College of Psychiatrists, said: “People with eating disorders should not be denied help based on their BMI. This could put them in a life-threatening position to reduce more weight in order to meet the threshold to access services.
“We urgently need resources and more funding for research if we’re to deal with the hidden epidemic of eating disorders this pandemic has brought on.
“At the same time, public health messaging on weight management must take into account sensitivities around body image and the complexities of this mental illness. That’s why it’s vital that patients with eating disorders and the mental health professionals who support them are part of the conversation shaping the anti-obesity strategy.”
A Department of Health and Social Care spokesperson said: “We know poor body image can be a factor in disordered eating for both men and women and we are committed to improving outcomes for those with eating disorders and related mental health issues – with record funding to expand dedicated services in the community.
“Early intervention services are being launched for young people with eating disorders which could see them begin treatment within two weeks.
“With over six in 10 adults overweight or living with obesity it is important that we take action to help people live healthier lives, and our approach is guided by the latest research and emerging evidence. NHS England has been clear it does not support the use of BMI thresholds.”
