New research indicates that people who stop using blockbuster slimming jabs like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who stop conventional lifestyle regimens.
Findings released in a prominent medical journal demonstrates that while obese individuals can lose a large proportion of their total mass while using the jabs, the weight is regained at an average rate of nearly a kilo each month upon discontinuation.
"People using these treatments should be aware of the risk of rapid weight regain when the therapy concludes," warns expert Dr. Susan Jebb.
That rate of recovery means a reversion to pre-treatment mass in about 18 months.
Weighing Treatments
The research, which looked at dozens of trials involving thousands of participants, compared the outcomes of GLP-1 agonists with conventional dieting.
Researchers emphasize that individuals who shed pounds through lifestyle changes alone usually have a more gradual creep back—around 100 grams monthly—post-intervention.
Understanding the Quick Rebound
Doctors suggest the mechanism of the jabs is key to understanding the heightened rebound.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than the body's typical production might result in the system to produce less of its endogenous GLP-1, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement leads to hunger is no longer kept in check, making excessive eating a significant risk."
A Lifelong Issue?
Medical guidelines advise the jabs for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
A number of clinicians contend that, considering the significant potential of relapse, the therapy might need to be ongoing.
This perspective is reinforced by pharmaceutical companies, who note that the results "highlight the persistent nature of excess weight," akin to managing conditions like hypertension.
Patient Experiences
People who have come off the medication explain a sudden resurgence of appetite.
"I experienced a switch flipping and you become ravenous," described an individual.
The struggle is worsened if patients have not developed sustainable dietary or behavioural modifications during therapy.
Significant Adoption
Recent estimates indicate that millions of people in the UK have used weight-loss jabs in the last 12 months, with desire being substantial.
- Use is higher among women compared to males.
- The middle-aged age group shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, clinicians caution that while the jabs are potent agents for weight loss, they are not a standalone solution and lasting health benefits likely depends on ongoing lifestyle changes.
