Fresh analysis reveals that patients who discontinue new slimming jabs like Mounjaro or Wegovy can put back on lost weight much more quickly than those who stop conventional diet and exercise plans.
Research printed in a major medical journal demonstrates that while overweight people can lose a large proportion of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"People purchasing such treatments need to be aware of the potential of rapid rebound weight gain when the medication is stopped," warns lead investigator Dr. Susan Jebb.
This pace of recovery suggests a return to pre-treatment weight within about a year and a half.
Analyzing Therapies
The study, which examined dozens of studies involving over 9,000 of participants, compared the results of these new drugs with older methods.
Researchers note that people who lose weight through lifestyle changes alone typically experience a less rapid weight regain—perhaps 100 grams monthly—after stopping.
The Reason for the Quick Rebound
Nutrition scientists believe the mode of action of the drugs explains the heightened regain.
The injections imitate a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone levels far above than normal might result in the body to produce less of its own natural hormone, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement means appetite is unsuppressed, making overeating far more likely."
A Lifelong Disease?
Medical guidelines recommend the jabs for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Many experts contend that, given the likelihood of weight regain, the therapy is often long-term.
This opinion is supported by drug manufacturers, who say that the results "emphasize the persistent character of excess weight," comparing it to managing diseases like hypertension.
User Accounts
Users who have stopped the jabs explain a powerful return of hunger.
"It felt as if a trigger activating and you become starving," recalled one woman.
The struggle is compounded if users have not adopted lasting lifestyle or habit modifications during therapy.
Growing Interest
Recent estimates suggest that millions of adults in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Use is more common among females than males.
- The 40s and 50s demographic shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while GLP-1 drugs are effective agents for weight loss, they are not a standalone solution and maintained weight loss relies on combined lifestyle support.
