Following the NHS’ recent rollout of weight loss injection, Mounjaro, research suggests that the UK is losing interest in traditional, organised weight-loss methods.
According to reports, WeightWaters’ revenue has more than halved since 2018, and Slimming World searches have dropped by 44%. In contrast, interest in prescription weight-loss drugs like Mounjaro has exploded by a whopping 3,900% year on year.
The medication has so far been highly effective at helping people lose weight, with experts predicting a decline in obesity rates for the first time by the end of 2025.
As interest in weight-loss injections grows, Mounjaro experts at leading online pharmacy and trusted NHS healthcare provider, Chemist4U, share their insights.
Ayesha Bashir, prescribing pharmacist and Mounjaro expert at Chemist4U, says, “Weight loss injections like Mounjaro are revolutionising the way people lose weight. More and more obesity patients are moving away from traditional, rules-based programs and increasingly turning to clinical, medically guided solutions that offer long-term results.
“Traditional diet programmes, which were once household staples, are losing relevance. The data points to a fundamental change in how the public is searching for and likely achieving weight loss.”
Weight loss search trends – is it the demise of dieting?
Statistics show that interest in traditional weight-loss methods, including diets and organised weight-loss programmes, has dropped significantly in recent years.
In 2021, ‘WeightWatchers’ was searched around 9,000 times a month in the UK. By 2025, that number had fallen to 4,700 searches, a 48% decline. Similarly, searches for ‘Slimming World’ dropped from 195,000 to 110,000 a month, down 44%.
As a result, WeightWatchers has lost over 50% of its total revenue since 2018. This decline followed its rebrand to “WW,” which never quite resonated with consumers, but was accelerated as medications like Ozempic and Mounjaro became available. By May 2025, WeightWatchers filed for U.S. bankruptcy and teamed with a provider of weight-loss jabs.
Chemist4U says, “This was a move born out of necessity, not innovation. It wasn’t just a business shift, it signals a cultural change where weight loss is no longer about discipline, points, or plans. It’s about medical solutions that promise faster, more sustainable outcomes.”
More generally, broader search terms are reflecting this shift, too. Statistics show that, over the past five years, monthly searches for ‘dieting’ have fallen by nearly 50%, from 700 to 360. Similarly, searches for ‘intermittent fasting’ dropped from 84,000 to 64,000, down 24%. At the same time, the number of searches for ‘Mounjaro’ rose from 100 a month in 2021 to an astonishing 905,000 in 2025 – an increase of over 900,000%.
Despite not being approved in the UK until 2024, Mounjaro has quickly gained popularity. In fact, the UK has witnessed the highest surge in global interest – with monthly searches jumping 4,049% in just one year, outpacing every other country.
Ayesha Bashir says, “The explosive growth in searches for medications like Mounjaro highlights a fundamental shift in how people approach weight loss. These prescription drugs offer a medically supervised, science-backed alternative to traditional diets, which many find more effective and easier to sustain.
“The rise in terms like ‘weight loss injections’ shows that patients and consumers are increasingly seeking quicker, clinically supported solutions, reflecting growing trust in pharmaceutical options as part of their weight management journey.”
