Fresh analysis indicates that people who stop using popular slimming jabs like Wegovy and Mounjaro may regain lost weight much more quickly than those who stop traditional lifestyle regimens.
Published data in a prominent health publication shows that while obese individuals frequently drop a large proportion of their total mass while on the medication, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using these drugs must be informed of the danger of fast weight regain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
This pace of recovery implies a reversion to pre-treatment weight in about a year and a half.
Weighing Therapies
The research, which examined dozens of trials involving thousands of participants, compared the results of the injectable medications with older methods.
Scientists note that people who lose weight through dieting typically experience a less rapid creep back—around 100 grams monthly—post-intervention.
The Reason for the Fast Rebound
Nutrition scientists suggest the way of the injections explains the heightened weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Sustained high doses of GLP-1 concentrations several times higher than normal might result in the system to generate a reduced amount of its own natural GLP-1, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication results in appetite is unsuppressed, making overeating far more likely."
A Lifelong Issue?
Medical guidelines advise the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, given the significant potential of relapse, the therapy is often long-term.
This view is supported by pharmaceutical companies, who note that the findings "highlight the persistent nature of excess weight," comparing it to managing diseases like hypertension.
User Accounts
Individuals who have discontinued the jabs explain a powerful resurgence of cravings.
"It felt as if a trigger flipping and I was suddenly starving," recalled one woman.
This difficulty is exacerbated if individuals have not developed lasting dietary or behavioural changes during therapy.
Growing Interest
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Use is greater among females compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, clinicians stress that while these medications are potent agents for weight loss, they are not a permanent cure and long-term success relies on ongoing lifestyle support.
