New research suggests that people who discontinue popular slimming jabs like Mounjaro or Wegovy may regain shed pounds far faster than those who halt conventional lifestyle programs.
Research printed in a prominent medical journal demonstrates that while obese individuals often shed about a fifth of their body weight while using the jabs, the weight comes back at an average rate of 0.8 kg per month after stopping.
"People purchasing these treatments must be cognizant of the potential of rapid rebound weight gain when the medication is stopped," warns expert Dr. Susan Jebb.
This pace of regain suggests a return to starting weight in about one and a half years.
Comparing Therapies
The research, which reviewed 37 of studies involving over 9,000 of participants, compared the effects of these new drugs with older methods.
Scientists emphasize that people who shed pounds through lifestyle changes alone typically experience a slower weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Rapid Regain
Nutrition scientists propose the way of the drugs explains the amplified rebound.
These medications copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels several times higher than normal could lead to the body to produce less of its endogenous GLP-1, and may also reduce responsiveness to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement leads to appetite is unsuppressed, making overeating much more probable."
A Lifelong Issue?
Medical guidelines recommend the injections for individuals with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians contend that, due to the high risk of weight regain, the treatment might need to be ongoing.
This opinion is echoed by drug manufacturers, who say that the results "emphasize the chronic nature of excess weight," similar to managing conditions like hypertension.
User Testimonies
People who have discontinued the jabs report a intense resurgence of hunger.
"I experienced something that goes on and you become extremely hungry," described an individual.
The struggle is exacerbated if users have not established lasting dietary or behavioural modifications during therapy.
Significant Adoption
Recent estimates indicate that a significant number of adults in the UK have used these injections in the last 12 months, with demand remaining high.
- Adoption is higher among women than men.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
In conclusion, experts emphasize that while these medications are potent agents for weight loss, they are not a standalone cure and long-term success hinges on integrated behavioural management.
