A recent study suggests that patients who come off new GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds at a significantly accelerated pace than those who stop conventional diet and exercise plans.
Findings released in a prominent health publication demonstrates that while overweight individuals frequently drop about a fifth of their total mass while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"People buying these drugs need to be informed of the potential of fast weight regain when the medication is stopped," warns expert Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment mass in about a year and a half.
Comparing Therapies
The research, which examined dozens of studies involving thousands of participants, contrasted the outcomes of these new drugs with older methods.
Scientists point out that individuals who lose weight through diet and exercise usually see a slower creep back—around 100 grams monthly—post-intervention.
Understanding the Fast Regain
Doctors propose the mechanism of the drugs explains the accelerated weight return.
These medications mimic a natural hormone called GLP-1, which helps regulate appetite.
"Long-term administration of the hormone levels several times higher than the body's typical production could lead to the system to produce less of its endogenous hormone, and may also lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this GLP-1 'fix' means appetite is uncontrolled, making excessive eating a significant risk."
An Ongoing Issue?
The NHS suggest the jabs for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, given the significant potential of relapse, the therapy might need to be long-term.
This opinion is echoed by pharmaceutical companies, who say that the results "emphasize the long-term nature of obesity," comparing it to managing diseases like hypertension.
User Experiences
Users who have come off the medication describe a powerful return of cravings.
"It was like something that goes on and I was suddenly starving," recalled an individual.
This challenge is worsened if users have not adopted lasting dietary or behavioural changes during therapy.
Growing Use
Recent estimates indicate that a significant number of people in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Use is greater among females compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while these medications are potent agents for weight loss, they are not a permanent fix and long-term success hinges on ongoing lifestyle changes.
