Users Coming Off Anti-Obesity Jabs Gain Back Weight at a Quadrupled Rate Than People Using Diet and Exercise

Fresh analysis suggests that people who discontinue blockbuster slimming jabs like semaglutide or tirzepatide tend to recover lost weight far faster than those who end conventional diet and exercise programs.

Findings released in a major medical journal shows that while obese people often shed about a fifth of their body weight while using the jabs, the weight is regained at an average rate of 0.8 kg per month once they quit.

"People purchasing these treatments must be aware of the potential of fast weight regain when the therapy concludes," cautioned lead investigator Dr. Susan Jebb.

That rate of regain means a return to starting mass in about one and a half years.

Weighing Treatments

The study, which examined dozens of studies involving thousands of patients, compared the outcomes of these new drugs with other pills.

Scientists emphasize that individuals who lose weight through dieting typically see a slower weight regain—around 100 grams monthly—once they finish.

The Reason for the Quick Rebound

Nutrition scientists propose the way of the jabs explains the accelerated weight return.

These medications copy a body's own chemical called GLP-1, which moderates hunger.

"Artificially providing the hormone concentrations several times higher than normal could lead to the system to generate a reduced amount of its endogenous GLP-1, and may also reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics researcher.

"Discontinuation of this GLP-1 'fix' results in hunger is no longer kept in check, making excessive eating a significant risk."

A Lifelong Condition?

Medical guidelines advise the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.

Many experts argue that, due to the likelihood of weight regain, the treatment might need to be long-term.

This view is reinforced by pharmaceutical companies, who note that the results "emphasize the long-term nature of obesity," comparing it to managing conditions like hypertension.

Patient Experiences

Individuals who have discontinued the jabs report a sudden resurgence of cravings.

"It felt as if a switch that goes on and you're instantly ravenous," said an individual.

This challenge is compounded if users have not established lasting dietary or behavioural modifications during treatment.

Significant Adoption

Survey data indicate that a significant number of adults in the UK have tried weight-loss jabs in the past year, with desire remaining high.

• Adoption is more common among females compared to men.
• The 40s and 50s age group shows the highest usage rates.
• A large proportion access the medications through private prescriptions rather than the NHS.

In conclusion, researchers stress that while these medications are powerful tools for shedding pounds, they are not a magic cure and maintained weight loss hinges on ongoing behavioural changes.
