New research suggests that individuals who come off new weight-loss injections like semaglutide or tirzepatide can put back on lost weight much more quickly than those who stop conventional diet and exercise regimens.
Published data in a leading medical journal shows that while obese individuals can lose a large proportion of their body weight while undergoing treatment, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals purchasing these treatments must be cognizant of the potential of quick weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
That rate of recovery suggests a return to pre-treatment mass within about a year and a half.
Weighing Approaches
The research, which reviewed dozens of studies involving thousands of participants, compared the results of these new drugs with other pills.
Researchers emphasize that individuals who shed pounds through diet and exercise typically have a less rapid weight regain—approximately 100 grams monthly—post-intervention.
Explaining the Rapid Regain
Nutrition scientists believe the way of the jabs is key to understanding the amplified regain.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing GLP-1 concentrations several times higher than normal might result in the system to produce less of its own natural hormone, and may also reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication means appetite is no longer kept in check, making overeating a significant risk."
A Chronic Condition?
Medical guidelines advise the injections for individuals with weight-linked health risks, alongside prescribed lifestyle changes.
A number of clinicians contend that, due to the significant potential of relapse, the treatment might need to be life-long.
This view is reinforced by drug manufacturers, who say that the results "underscore the chronic character of obesity," similar to managing conditions like hypertension.
User Accounts
Users who have stopped the jabs explain a intense return of hunger.
"It felt as if a trigger flipping and you're instantly ravenous," recalled a patient.
The struggle is exacerbated if patients have not established permanent dietary or behavioural changes during treatment.
Growing Adoption
Survey data indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Use is greater among females 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 caution that while GLP-1 drugs are effective tools for shedding pounds, they are not a permanent solution and long-term success hinges on ongoing lifestyle management.
