Fresh analysis indicates that individuals who stop using blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover lost weight much more quickly than those who halt traditional diet and exercise plans.
Research printed in a leading health publication shows that while overweight individuals can lose substantial amounts of their total mass while using the jabs, the weight is regained at an average rate of 0.8 kg per month after stopping.
"Users purchasing these treatments need to be aware of the potential of rapid weight regain when the treatment concludes," stated researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment mass in about 18 months.
Analyzing Approaches
The study, which reviewed dozens of studies involving over 9,000 of participants, compared the results of the injectable medications with older methods.
Scientists point out that people who shed pounds through lifestyle changes alone generally experience a slower weight regain—around 100 grams monthly—once they finish.
Explaining the Fast Regain
Experts suggest the mechanism of the jabs accounts for the heightened regain.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than normal might result in the system to produce less of its endogenous GLP-1, and could diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication leads to hunger is no longer kept in check, making excessive eating far more likely."
A Chronic Condition?
Medical guidelines recommend the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Professionals say that, given the likelihood of weight regain, the treatment is often ongoing.
This view is echoed by drug manufacturers, who state that the findings "highlight the chronic character of obesity," akin to managing diseases like high blood pressure.
Patient Testimonies
Individuals who have come off the medication explain a sudden resurgence of hunger.
"I experienced a switch that goes on and you're instantly ravenous," said one woman.
This difficulty is compounded if patients have not adopted permanent lifestyle or habit changes during therapy.
Widespread Use
Recent estimates indicate that millions of adults in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Adoption is greater among females than males.
- The 40s and 50s age group shows the highest usage rates.
- Many access the drugs through private healthcare rather than the NHS.
In conclusion, experts caution that while the jabs are potent tools for shedding pounds, they are not a standalone solution and lasting health benefits relies on combined behavioural support.
