A recent study indicates that people who discontinue popular slimming jabs like Wegovy and Mounjaro may regain lost weight at a significantly accelerated pace than those who halt conventional lifestyle programs.
Published data in a major health publication demonstrates that while obese people can lose about a fifth of their body weight while on the medication, the mass returns at an estimated rate of nearly a kilo each month after stopping.
"People buying these drugs need to be aware of the potential of fast rebound weight gain when the treatment is stopped," warns expert Dr. Susan Jebb.
This pace of recovery suggests a reversion to starting mass in about a year and a half.
Comparing Therapies
The study, which looked at dozens of trials involving thousands of participants, compared the outcomes of the injectable medications with other pills.
The team emphasize that individuals who lose weight through lifestyle changes alone usually see a less rapid creep back—perhaps 100 grams monthly—once they finish.
Understanding the Rapid Regain
Experts propose the mode of action of the injections explains the amplified rebound.
The injections copy a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 levels far above than normal might result in the body to generate a reduced amount of its own natural hormone, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement means appetite is uncontrolled, making overeating far more likely."
A Chronic Condition?
The NHS advise the jabs for people with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians say that, due to the likelihood of weight regain, the therapy might need to be ongoing.
This opinion is reinforced by pharmaceutical companies, who state that the findings "underscore the persistent nature of obesity," akin to managing conditions like high blood pressure.
User Testimonies
Users who have stopped the jabs describe a powerful resurgence of hunger.
"It was like a trigger flipping and you're instantly extremely hungry," described an individual.
This difficulty is exacerbated if users have not adopted sustainable lifestyle or habit modifications during treatment.
Significant Adoption
Survey data indicate that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with desire remaining high.
- Use is more common among women compared to males.
- The middle-aged age group shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
Finally, experts stress that while GLP-1 drugs are potent tools for shedding pounds, they are not a standalone fix and lasting health benefits hinges on combined lifestyle changes.
