A recent study reveals that individuals who come off blockbuster slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who stop conventional lifestyle programs.
Published data in a major medical journal demonstrates that while obese individuals frequently drop substantial amounts of their body weight while on the medication, the weight returns at an average rate of nearly a kilo each month once they quit.
"People buying these medications must be cognizant of the risk of fast rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
That rate of recovery means a return to pre-treatment weight within about a year and a half.
Comparing Approaches
The research, which reviewed 37 of trials involving over 9,000 of patients, contrasted the outcomes of the injectable medications with other pills.
Scientists point out that people who lose weight through lifestyle changes alone typically experience a less rapid creep back—around 0.1 kg a month—after stopping.
Understanding the Quick Regain
Experts suggest the mode of action of the jabs explains the amplified rebound.
These medications copy a body's own chemical called GLP-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations several times higher than normal may cause the system to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement results in hunger is no longer kept in check, making binge eating a significant risk."
An Ongoing Disease?
Health authorities suggest the injections for individuals with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians contend that, given the high risk of relapse, the therapy should be considered life-long.
This opinion is reinforced by pharmaceutical companies, who note that the results "highlight the chronic character of excess weight," comparing it to managing conditions like hypertension.
User Experiences
Individuals who have come off the jabs explain a intense resurgence of hunger.
"It felt as if a trigger that goes on and I was suddenly extremely hungry," recalled a patient.
The struggle is worsened if users have not developed sustainable lifestyle or habit modifications during treatment.
Widespread Use
Figures suggest that millions of people in the UK have used weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is greater among women than males.
- The 40s and 50s demographic shows the highest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, experts stress that while GLP-1 drugs are potent agents for weight loss, they are not a magic cure and maintained weight loss likely depends on integrated behavioural changes.
