Fresh analysis suggests that individuals who come off popular weight-loss injections like Wegovy and Mounjaro can put back on reduced body mass far faster than those who end conventional lifestyle plans.
Research printed in a leading health publication demonstrates that while obese individuals often shed a large proportion of their total mass while using the jabs, the mass returns at an average rate of 0.8 kg per month after stopping.
"Individuals purchasing these drugs need to be cognizant of the risk of rapid weight regain when the medication ends," warns lead investigator Dr. Susan Jebb.
That rate of regain means a reversion to pre-treatment mass within about 18 months.
Analyzing Therapies
The study, which reviewed dozens of trials involving thousands of patients, contrasted the outcomes of these new drugs with older methods.
The team point out that individuals who shed pounds through diet and exercise usually experience a less rapid creep back—around 0.1 kg a month—once they finish.
The Reason for the Rapid Regain
Nutrition scientists suggest the mechanism of the jabs is key to understanding the heightened weight return.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 levels far above than normal might result in the system to produce less of its endogenous GLP-1, and may also reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication means hunger is no longer kept in check, making excessive eating a significant risk."
A Lifelong Issue?
Health authorities suggest the jabs for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts contend that, given the significant potential of relapse, the treatment might need to be ongoing.
This opinion is reinforced by drug manufacturers, who note that the findings "underscore the chronic character of excess weight," akin to managing conditions like high blood pressure.
Patient Accounts
People who have come off the jabs report a sudden return of hunger.
"I experienced a switch that goes on and I was suddenly ravenous," described one woman.
This difficulty is worsened if patients have not developed sustainable lifestyle or habit modifications during treatment.
Growing Adoption
Recent estimates show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.
- Use is higher among females compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers stress that while the jabs are powerful agents for weight loss, they are not a permanent solution and long-term success hinges on combined behavioural support.
