Fresh analysis indicates that people who come off new slimming jabs like Wegovy and Mounjaro tend to recover lost weight far faster than those who end conventional lifestyle programs.
Research printed in a leading health publication shows that while obese people frequently drop substantial amounts of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month upon discontinuation.
"Users buying such drugs must be cognizant of the risk of fast rebound weight gain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
That rate of recovery suggests a reversion to pre-treatment mass in about 18 months.
Comparing Approaches
The analysis, which reviewed dozens of studies involving thousands of participants, compared the outcomes of these new drugs with conventional dieting.
Researchers point out that individuals who shed pounds through lifestyle changes alone usually see a slower creep back—approximately 100 grams monthly—post-intervention.
Understanding the Quick Regain
Nutrition scientists propose the mode of action of the injections explains the heightened weight return.
GLP-1 drugs imitate a natural hormone called GLP-1, which helps regulate appetite.
"Long-term administration of the hormone levels several times higher than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating far more likely."
A Lifelong Issue?
The NHS recommend the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Professionals contend that, given the likelihood of relapse, the treatment is often ongoing.
This opinion is echoed by pharmaceutical companies, who state that the results "highlight the persistent nature of excess weight," similar to managing conditions like diabetes.
User Experiences
Individuals who have stopped the medication report a powerful resurgence of cravings.
"It was like a trigger flipping and you're instantly starving," said one woman.
The struggle is compounded if individuals have not developed lasting dietary or behavioural changes during treatment.
Growing Use
Survey data show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with interest continuing to grow.
- Use is greater among women than males.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion obtain the medications through private healthcare rather than the NHS.
In conclusion, clinicians stress that while the jabs are potent agents for shedding pounds, they are not a standalone cure and maintained weight loss hinges on ongoing lifestyle changes.
