A recent study suggests that people who come off popular weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass far faster than those who halt conventional lifestyle regimens.
Published data in a leading health publication points out that while obese people frequently drop about a fifth of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"People purchasing these medications should be aware of the risk of fast rebound weight gain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to original mass in about one and a half years.
Weighing Treatments
The study, which examined 37 of studies involving thousands of patients, contrasted the results of GLP-1 agonists with older methods.
Researchers point out that people who shed pounds through lifestyle changes alone usually see a slower creep back—perhaps 0.1 kg a month—post-intervention.
Explaining the Fast Regain
Experts suggest the mechanism of the injections explains the heightened rebound.
GLP-1 drugs mimic a body's own chemical called GLP-1, which moderates appetite.
"Sustained high doses of the hormone concentrations far above than the body's typical production might result in the body to produce less of its own natural GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' results in appetite is unsuppressed, making binge eating a significant risk."
A Chronic Issue?
Health authorities suggest the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
Many experts say that, due to the likelihood of relapse, the treatment might need to be life-long.
This perspective is supported by pharmaceutical companies, who say that the results "underscore the long-term nature of obesity," similar to managing diseases like high blood pressure.
User Accounts
Individuals who have come off the jabs explain a powerful return of cravings.
"I experienced a trigger that goes on and I was suddenly ravenous," said one woman.
This challenge is worsened if users have not developed permanent dietary or behavioural modifications during therapy.
Growing Use
Figures show that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with interest being substantial.
- Adoption is higher among females compared to men.
- The middle-aged demographic shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, clinicians caution that while GLP-1 drugs are potent agents for weight loss, they are not a permanent cure and long-term success likely depends on combined lifestyle management.
