Fresh analysis indicates that individuals who stop using new slimming jabs like Wegovy and Mounjaro may regain shed pounds far faster than those who stop conventional lifestyle programs.
Published data in a prominent health publication shows that while obese people often shed a large proportion of their body weight while on the medication, the weight is regained at an average rate of nearly a kilo each month after stopping.
"Individuals using these drugs should be informed of the danger of fast rebound weight gain when the medication concludes," cautioned expert Dr. Susan Jebb.
That rate of recovery suggests a reversion to original weight within about one and a half years.
Analyzing Treatments
The study, which looked at 37 of studies involving thousands of participants, contrasted the effects of the injectable medications with older methods.
Scientists note that individuals who lose weight through lifestyle changes alone generally have a slower creep back—around 100 grams monthly—after stopping.
Explaining the Fast Regain
Nutrition scientists suggest the mode of action of the drugs is key to understanding the amplified regain.
The injections mimic a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of the hormone levels several times higher than normal might result in the system to generate a reduced amount of its endogenous hormone, and could diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this medication results in hunger is unsuppressed, making overeating a significant risk."
An Ongoing Issue?
The NHS suggest the jabs for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Professionals say that, given the likelihood of relapse, the treatment is often life-long.
This opinion is supported by pharmaceutical companies, who note that the results "emphasize the chronic character of obesity," similar to managing diseases like hypertension.
User Experiences
Individuals who have discontinued the medication describe a sudden resurgence of cravings.
"I experienced a switch flipping and I was suddenly starving," said a patient.
The struggle is exacerbated if users have not established permanent lifestyle or habit changes during therapy.
Significant Use
Recent estimates indicate that a significant number of people in the UK have tried these injections in the last 12 months, with desire being substantial.
- Use is greater among women compared to men.
- The 40s and 50s age group shows the highest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
Ultimately, clinicians emphasize that while the jabs are potent agents for weight loss, they are not a standalone fix and lasting health benefits hinges on combined behavioural changes.
