New research indicates that individuals who discontinue new weight-loss injections like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who end conventional lifestyle regimens.
Findings released in a prominent medical journal demonstrates that while obese individuals frequently drop a large proportion of their body weight while using the jabs, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Users using such treatments must be informed of the risk of quick rebound weight gain when the treatment concludes," warns expert Dr. Susan Jebb.
Such speed of regain suggests a return to pre-treatment weight within about 18 months.
Analyzing Approaches
The research, which examined dozens of studies involving over 9,000 of participants, contrasted the outcomes of the injectable medications with other pills.
Scientists point out that people who shed pounds through diet and exercise generally experience a slower weight regain—around 0.1 kg a month—post-intervention.
Understanding the Rapid Rebound
Experts propose the mechanism of the jabs explains the accelerated regain.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of the hormone concentrations far above than the body's typical production could lead to the system to produce less of its own natural hormone, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication results in appetite is uncontrolled, making overeating a significant risk."
An Ongoing Condition?
The NHS advise the injections for people with obesity-related medical conditions, accompanied by recommended lifestyle changes.
Professionals say that, due to the likelihood of weight regain, the treatment should be considered long-term.
This view is supported by drug manufacturers, who state that the results "emphasize the long-term character of obesity," comparing it to managing diseases like hypertension.
User Testimonies
Individuals who have stopped the medication describe a powerful resurgence of hunger.
"It felt as if a trigger that goes on and I was suddenly extremely hungry," said one woman.
This challenge is compounded if individuals have not developed permanent lifestyle or habit modifications during treatment.
Widespread Interest
Figures indicate that millions of people in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Adoption is more common among women compared to men.
- The middle-aged demographic shows the greatest level of interest.
- Many access the medications through private prescriptions rather than the NHS.
Finally, researchers caution that while these medications are effective tools for weight loss, they are not a permanent fix and lasting health benefits likely depends on combined behavioural management.
