New research suggests that people who stop using new GLP-1 drugs like Mounjaro or Wegovy tend to recover shed pounds at a significantly accelerated pace than those who end traditional lifestyle programs.
Published data in a leading health publication shows that while overweight people can lose about a fifth of their body weight while using the jabs, the weight is regained at an average rate of nearly a kilo each month upon discontinuation.
"People buying such medications should be aware of the potential of fast weight regain when the medication is stopped," cautioned expert Dr. Susan Jebb.
This pace of regain implies a return to original mass in about one and a half years.
Analyzing Therapies
The research, which looked at dozens of trials involving thousands of patients, contrasted the effects of these new drugs with conventional dieting.
Researchers point out that individuals who shed pounds through lifestyle changes alone usually experience a slower creep back—around 100 grams monthly—after stopping.
The Reason for the Quick Rebound
Nutrition scientists suggest the mode of action of the jabs accounts for the amplified weight return.
GLP-1 drugs copy a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than normal could lead to the system to produce less of its own natural hormone, and could reduce sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Stopping of this medication leads to hunger is unsuppressed, making overeating much more probable."
A Chronic Issue?
Health authorities advise the injections for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, given the likelihood of weight regain, the treatment is often long-term.
This perspective is supported by drug manufacturers, who note that the results "highlight the long-term character of excess weight," comparing it to managing diseases like hypertension.
User Testimonies
Users who have come off the jabs describe a intense resurgence of cravings.
"It felt as if a switch that goes on and I was suddenly ravenous," said a patient.
This challenge is exacerbated if users have not adopted lasting lifestyle or habit changes during treatment.
Widespread Interest
Recent estimates show that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with demand remaining high.
- Adoption is more common among females than men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
Finally, clinicians caution that while these medications are potent agents for weight loss, they are not a standalone fix and lasting health benefits relies on combined behavioural management.
