A recent study indicates that individuals who come off new weight-loss injections like semaglutide or tirzepatide may regain lost weight far faster than those who stop conventional diet and exercise programs.
Research printed in a prominent health publication points out that while obese individuals frequently drop a large proportion of their body weight while using the jabs, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Users purchasing such drugs should be cognizant of the danger of fast weight regain when the treatment ends," warns expert Dr. Susan Jebb.
Such speed of regain implies a return to original weight in about a year and a half.
Analyzing Approaches
The research, which reviewed dozens of studies involving thousands of patients, contrasted the results of these new drugs with older methods.
Researchers note that individuals who shed pounds through lifestyle changes alone usually have a more gradual weight regain—around 0.1 kg a month—after stopping.
Understanding the Rapid Rebound
Nutrition scientists propose the mode of action of the injections accounts for the amplified weight return.
These medications mimic a body's own chemical called glucagon-like peptide-1, which moderates 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 could reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means hunger is no longer kept in check, making binge eating much more probable."
A Chronic Issue?
Health authorities recommend the injections for individuals with obesity-related medical conditions, alongside prescribed lifestyle changes.
Professionals say that, given the likelihood of weight regain, the therapy should be considered ongoing.
This perspective is supported by pharmaceutical companies, who note that the findings "highlight the persistent character of excess weight," comparing it to managing diseases like high blood pressure.
User Testimonies
Users who have stopped the jabs explain a intense return of cravings.
"It felt as if a switch flipping and you become extremely hungry," recalled an individual.
This difficulty is worsened if individuals have not adopted sustainable lifestyle or habit modifications during therapy.
Widespread Use
Recent estimates suggest that millions of people in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is more common among females than males.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than public health services.
Ultimately, clinicians caution that while GLP-1 drugs are effective agents for weight loss, they are not a magic cure and long-term success relies on ongoing lifestyle management.
