A recent study reveals that individuals who come off blockbuster weight-loss injections like semaglutide or tirzepatide tend to recover lost weight at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Research printed in a leading medical journal demonstrates that while obese individuals can lose a large proportion of their body weight while using the jabs, the weight returns at an estimated rate of 0.8 kg per month after stopping.
"Individuals using these drugs need to be cognizant of the danger of fast weight regain when the medication ends," stated lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment weight within about 18 months.
Weighing Approaches
The analysis, which looked at dozens of trials involving thousands of patients, contrasted the effects of these new drugs with older methods.
The team emphasize that individuals who shed pounds through dieting generally have a slower weight regain—around 0.1 kg a month—once they finish.
Explaining the Rapid Regain
Experts suggest the mode of action of the jabs accounts for the heightened regain.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone concentrations far above than the body's typical production could lead to the body to produce less of its endogenous hormone, and could reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement means appetite is no longer kept in check, making overeating far more likely."
A Lifelong Issue?
Health authorities suggest the injections for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians argue that, due to the high risk of relapse, the treatment should be considered long-term.
This opinion is reinforced by pharmaceutical companies, who note that the findings "highlight the chronic character of obesity," comparing it to managing diseases like hypertension.
User Experiences
People who have come off the medication explain a intense resurgence of appetite.
"It was like a trigger activating and you become extremely hungry," described an individual.
This difficulty is compounded if users have not adopted lasting dietary or behavioural changes during therapy.
Growing Use
Survey data show that millions of adults in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is more common among women compared to men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, clinicians emphasize that while the jabs are effective agents for weight loss, they are not a permanent solution and lasting health benefits relies on combined lifestyle management.
