New research reveals that patients who come off popular GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass at a significantly accelerated pace than those who halt conventional diet and exercise regimens.
Findings released in a prominent medical journal points out that while overweight individuals frequently drop substantial amounts of their body weight while on the medication, the mass returns at an average rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing these drugs must be aware of the risk of rapid rebound weight gain when the therapy concludes," warns expert Dr. Susan Jebb.
That rate of recovery implies a return to original mass within about one and a half years.
Comparing Treatments
The research, which looked at dozens of trials involving thousands of participants, contrasted the results of GLP-1 agonists with older methods.
The team emphasize that individuals who shed pounds through dieting generally see a slower weight regain—around 100 grams monthly—post-intervention.
Explaining the Fast Regain
Nutrition scientists suggest the mechanism of the injections explains the heightened regain.
These medications imitate a natural hormone called GLP-1, which helps regulate hunger.
"Artificially providing GLP-1 levels several times higher than the body's typical production may cause the system to produce less of its own natural hormone, and could lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement means hunger is unsuppressed, making overeating a significant risk."
A Lifelong Condition?
The NHS advise the jabs for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals contend that, considering the high risk of relapse, the treatment might need to be ongoing.
This opinion is reinforced by pharmaceutical companies, who note that the findings "underscore the persistent character of obesity," similar to managing conditions like hypertension.
Patient Accounts
Users who have come off the jabs describe a intense return of cravings.
"I experienced a trigger activating and I was suddenly ravenous," said one woman.
The struggle is exacerbated if users have not developed permanent dietary or behavioural changes during treatment.
Significant Interest
Recent estimates show that a significant number of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Use is more common among women compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians emphasize that while these medications are potent tools for shedding pounds, they are not a magic fix and maintained weight loss relies on combined lifestyle management.
