A recent study suggests that patients who stop using popular weight-loss injections like Mounjaro or Wegovy tend to recover shed pounds far faster than those who end traditional diet and exercise programs.
Findings released in a prominent medical journal shows that while overweight individuals frequently drop a large proportion of their body weight while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month after stopping.
"Users buying such drugs need to be aware of the risk of fast weight regain when the treatment concludes," stated lead investigator Dr. Susan Jebb.
That rate of regain implies a reversion to starting mass in about 18 months.
Weighing Treatments
The analysis, which looked at 37 of trials involving over 9,000 of participants, compared the effects of GLP-1 agonists with older methods.
Researchers emphasize that individuals who lose weight through lifestyle changes alone generally experience a less rapid creep back—around 100 grams monthly—post-intervention.
Understanding the Rapid Rebound
Experts propose the mechanism of the jabs explains the accelerated regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of the hormone levels far above than normal could lead to the system to produce less of its endogenous GLP-1, and may also reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' leads to hunger is no longer kept in check, making excessive eating much more probable."
An Ongoing Issue?
The NHS suggest the jabs for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.
A number of clinicians argue that, considering the likelihood of relapse, the therapy might need to be long-term.
This perspective is supported by drug manufacturers, who state that the results "underscore the persistent character of excess weight," comparing it to managing diseases like high blood pressure.
User Accounts
Individuals who have come off the jabs describe a intense return of appetite.
"I experienced a switch activating and I was suddenly starving," described a patient.
This challenge is exacerbated if patients have not established sustainable lifestyle or habit changes during therapy.
Growing Use
Recent estimates suggest that a significant number of adults in the UK have used these injections in the last 12 months, with interest being substantial.
- Adoption is more common among females compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, experts stress that while these medications are effective agents for shedding pounds, they are not a standalone solution and maintained weight loss likely depends on ongoing lifestyle changes.
