A recent study reveals that people who stop using blockbuster slimming jabs like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who halt traditional lifestyle plans.
Published data in a leading health publication shows that while obese people can lose about a fifth of their body weight while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Users buying such drugs must be cognizant of the danger of fast rebound weight gain when the medication ends," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a reversion to pre-treatment mass within about one and a half years.
Analyzing Therapies
The research, which examined dozens of trials involving over 9,000 of participants, compared the results of the injectable medications with older methods.
The team point out that individuals who lose weight through diet and exercise usually have a more gradual weight regain—perhaps 100 grams monthly—once they finish.
Explaining the Fast Regain
Nutrition scientists suggest the mechanism of the injections is key to understanding the accelerated weight return.
The injections imitate a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations far above than normal might result in the body to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' results in hunger is unsuppressed, making binge eating a significant risk."
A Chronic Disease?
The NHS suggest the jabs for individuals with obesity-related medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians argue that, due to the likelihood of relapse, the treatment should be considered ongoing.
This view is reinforced by pharmaceutical companies, who state that the findings "underscore the chronic nature of obesity," comparing it to managing diseases like hypertension.
Patient Experiences
Individuals who have discontinued the jabs describe a sudden resurgence of appetite.
"I experienced something activating and you're instantly extremely hungry," said an individual.
This challenge is compounded if patients have not developed permanent dietary or behavioural changes during therapy.
Widespread Adoption
Recent estimates show that a significant number of people in the UK have tried these injections in the last 12 months, with interest being substantial.
- Use is greater among women than males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers stress that while these medications are powerful tools for shedding pounds, they are not a standalone solution and lasting health benefits relies on ongoing behavioural changes.
