New research reveals that patients who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who halt traditional lifestyle programs.
Research printed in a major health publication demonstrates that while overweight individuals can lose a large proportion of their body weight while using the jabs, the mass returns at an average rate of nearly a kilo each month once they quit.
"Users buying such medications need to be informed of the risk of fast weight regain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery suggests a reversion to starting weight within about a year and a half.
Comparing Approaches
The study, which looked at dozens of trials involving thousands of participants, compared the effects of the injectable medications with conventional dieting.
Researchers point out that people who lose weight through diet and exercise typically experience a slower weight regain—around 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Experts suggest the way of the drugs is key to understanding the amplified rebound.
These medications copy a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Artificially providing the hormone concentrations far above than the body's typical production may cause the body to generate a reduced amount of its endogenous GLP-1, and could diminish sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication means hunger is no longer kept in check, making binge eating a significant risk."
An Ongoing Disease?
The NHS advise the injections for people with obesity-related health risks, accompanied by recommended lifestyle changes.
Many experts say that, due to the high risk of relapse, the therapy is often life-long.
This view is echoed by drug manufacturers, who note that the findings "highlight the chronic nature of excess weight," similar to managing diseases like hypertension.
User Accounts
Individuals who have stopped the medication describe a powerful return of cravings.
"It felt as if a switch activating and you become starving," described an individual.
The struggle is exacerbated if users have not developed sustainable dietary or behavioural modifications during treatment.
Widespread Interest
Recent estimates suggest that a significant number of adults in the UK have used these injections in the past year, with interest being substantial.
- Use is higher among females compared to men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than public health services.
In conclusion, clinicians caution that while these medications are potent agents for shedding pounds, they are not a magic solution and lasting health benefits likely depends on integrated behavioural changes.
