New research reveals that people who come off popular weight-loss injections like Wegovy and Mounjaro may regain shed pounds much more quickly than those who stop traditional lifestyle plans.
Published data in a prominent health publication demonstrates that while overweight people often shed a large proportion of their body weight while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"People buying these treatments should be cognizant of the danger of quick weight regain when the medication is stopped," stated expert Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment weight in about one and a half years.
Weighing Therapies
The research, which examined dozens of trials involving thousands of participants, contrasted the effects of the injectable medications with older methods.
Researchers emphasize that people who lose weight through diet and exercise generally have a slower creep back—perhaps 0.1 kg a month—post-intervention.
Explaining the Fast Rebound
Nutrition scientists believe the mechanism of the injections is key to understanding the heightened rebound.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of the hormone levels far above than the body's typical production could lead to the body to produce less of its endogenous GLP-1, and could reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this medication means appetite is uncontrolled, making excessive eating a significant risk."
An Ongoing Issue?
Health authorities advise the injections for people with weight-linked medical conditions, alongside recommended lifestyle changes.
A number of clinicians say that, considering the significant potential of weight regain, the therapy should be considered ongoing.
This opinion is echoed by drug manufacturers, who note that the findings "underscore the long-term nature of obesity," akin to managing diseases like diabetes.
User Experiences
Users who have stopped the jabs explain a powerful return of cravings.
"It felt as if a trigger flipping and I was suddenly extremely hungry," described a patient.
This difficulty is compounded if individuals have not developed sustainable dietary or behavioural changes during therapy.
Significant Adoption
Recent estimates indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Use is greater among women than men.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, clinicians stress that while these medications are potent agents for shedding pounds, they are not a standalone solution and lasting health benefits likely depends on ongoing behavioural support.
