Fresh analysis indicates that people who stop using blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds far faster than those who halt conventional diet and exercise plans.
Findings released in a prominent health publication demonstrates that while overweight individuals often shed substantial amounts of their total mass while using the jabs, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"Users purchasing such drugs should be aware of the risk of rapid weight regain when the medication ends," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to starting weight within about 18 months.
Weighing Approaches
The study, which examined 37 of trials involving over 9,000 of participants, contrasted the effects of the injectable medications with other pills.
The team note that people who shed pounds through dieting generally experience a less rapid weight regain—perhaps 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Nutrition scientists suggest the way of the drugs explains the amplified regain.
The injections mimic a body's own chemical called GLP-1, which helps regulate appetite.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production may cause the body to produce less of its endogenous GLP-1, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' means appetite is uncontrolled, making overeating a significant risk."
An Ongoing Disease?
The NHS advise the injections for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
A number of clinicians say that, due to the high risk of weight regain, the therapy might need to be ongoing.
This perspective is reinforced by pharmaceutical companies, who note that the findings "emphasize the long-term nature of excess weight," similar to managing diseases like hypertension.
Patient Accounts
People who have discontinued the jabs explain a sudden return of appetite.
"It felt as if a trigger that goes on and you're instantly starving," said one woman.
This difficulty is compounded if individuals have not adopted lasting dietary or behavioural modifications during therapy.
Significant Use
Figures suggest that a significant number of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Adoption is higher among females than males.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
In conclusion, clinicians stress that while the jabs are powerful agents for weight loss, they are not a magic cure and lasting health benefits likely depends on combined behavioural changes.
