Fresh analysis suggests that people who come off new slimming jabs like Mounjaro or Wegovy can put back on reduced body mass far faster than those who halt conventional lifestyle regimens.
Findings released in a major health publication shows that while overweight people can lose about a fifth of their total mass while using the jabs, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"People purchasing such treatments need to be cognizant of the danger of quick weight regain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
This pace of regain suggests a return to original mass within about one and a half years.
Weighing Approaches
The research, which looked at dozens of trials involving thousands of participants, compared the outcomes of GLP-1 agonists with other pills.
The team note that individuals who lose weight through dieting typically experience a less rapid creep back—perhaps 100 grams monthly—once they finish.
Explaining the Rapid Rebound
Nutrition scientists believe the way of the injections is key to understanding the accelerated regain.
These medications copy a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of the hormone concentrations far above than normal might result in the system to produce less of its own natural hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement means appetite is no longer kept in check, making overeating far more likely."
An Ongoing Disease?
The NHS recommend the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
Many experts say that, due to the high risk of relapse, the therapy might need to be ongoing.
This perspective is reinforced by drug manufacturers, who state that the results "highlight the long-term nature of excess weight," similar to managing conditions like high blood pressure.
User Accounts
Individuals who have discontinued the medication explain a intense resurgence of appetite.
"It felt as if a switch that goes on and I was suddenly extremely hungry," described one woman.
This challenge is worsened if patients have not adopted permanent dietary or behavioural modifications during treatment.
Widespread Adoption
Survey data suggest that millions of people in the UK have used these injections in the last 12 months, with demand continuing to grow.
- Use is higher among women than men.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, clinicians stress that while these medications are effective tools for weight loss, they are not a standalone fix and maintained weight loss likely depends on combined behavioural support.
