Fresh analysis reveals that patients who discontinue blockbuster slimming jabs like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who end traditional lifestyle regimens.
Findings released in a major health publication shows that while obese individuals often shed a large proportion of their total mass while using the jabs, the weight returns at an average rate of 0.8 kg per month upon discontinuation.
"Users purchasing these drugs must be informed of the danger of rapid weight regain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to starting mass in about a year and a half.
Comparing Approaches
The research, which examined 37 of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
The team point out that individuals who shed pounds through dieting generally experience a slower weight regain—around 0.1 kg a month—after stopping.
Explaining the Fast Regain
Nutrition scientists propose the mode of action of the jabs accounts for the heightened rebound.
These medications imitate a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production could lead to the body to produce less of its endogenous GLP-1, and could diminish sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement leads to appetite is unsuppressed, making excessive eating much more probable."
An Ongoing Condition?
The NHS recommend the injections for individuals with obesity-related health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, considering the likelihood of relapse, the therapy might need to be life-long.
This perspective is supported by drug manufacturers, who note that the findings "highlight the long-term character of obesity," comparing it to managing conditions like hypertension.
User Accounts
Users who have discontinued the jabs report a powerful return of hunger.
"It felt as if a trigger activating and you become ravenous," described an individual.
The struggle is worsened if patients have not adopted permanent dietary or behavioural modifications during treatment.
Growing Interest
Recent estimates indicate that a significant number of people in the UK have used these injections in the past year, with desire remaining high.
- Use is more common among women than men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
Finally, experts stress that while the jabs are powerful tools for weight loss, they are not a permanent cure and long-term success hinges on integrated lifestyle management.
