New research indicates that individuals who discontinue popular GLP-1 drugs like semaglutide or tirzepatide may regain lost weight far faster than those who end traditional diet and exercise plans.
Findings released in a prominent medical journal shows that while obese people can lose a large proportion of their total mass while using the jabs, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing these drugs need to be aware of the danger of quick weight regain when the treatment is stopped," stated researcher Dr. Susan Jebb.
That rate of regain means a reversion to original weight in about a year and a half.
Comparing Therapies
The study, which looked at 37 of studies involving over 9,000 of patients, compared the outcomes of these new drugs with older methods.
The team note that people who lose weight through diet and exercise generally experience a slower creep back—around 100 grams monthly—after stopping.
Explaining the Fast Regain
Nutrition scientists believe the way of the jabs explains the accelerated weight return.
The injections copy a body's own chemical called GLP-1, which helps regulate appetite.
"Artificially providing the hormone levels several times higher than the body's typical production might result in the body to produce less of its own natural GLP-1, and may also reduce responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' leads to hunger is unsuppressed, making excessive eating far more likely."
A Lifelong Disease?
The NHS advise the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals say that, due to the significant potential of weight regain, the treatment is often long-term.
This opinion is reinforced by pharmaceutical companies, who note that the results "underscore the persistent character of obesity," similar to managing diseases like hypertension.
User Accounts
Individuals who have stopped the jabs describe a intense return of hunger.
"I experienced a trigger activating and you become ravenous," said one woman.
The struggle is compounded if users have not developed lasting lifestyle or habit changes during therapy.
Significant Use
Recent estimates show that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with desire remaining high.
- Adoption is greater among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
Finally, experts caution that while the jabs are effective agents for shedding pounds, they are not a magic solution and maintained weight loss relies on combined lifestyle support.
