New research reveals that patients who stop using new slimming jabs like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who end conventional lifestyle regimens.
Findings released in a major medical journal points out that while obese people often shed substantial amounts of their body weight while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month after stopping.
"Individuals buying such drugs must be aware of the danger of rapid rebound weight gain when the treatment ends," stated expert Dr. Susan Jebb.
This pace of regain implies a reversion to pre-treatment mass in about a year and a half.
Analyzing Therapies
The analysis, which reviewed 37 of studies involving thousands of patients, compared the results of the injectable medications with older methods.
Researchers point out that people who shed pounds through lifestyle changes alone generally see a slower weight regain—approximately 100 grams monthly—post-intervention.
The Reason for the Rapid Rebound
Doctors propose the mode of action of the injections explains the amplified rebound.
These medications copy a body's own chemical called GLP-1, which helps regulate appetite.
"Artificially providing the hormone concentrations several times higher than the body's typical production might result in the body to produce less of its own natural GLP-1, and could diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making overeating a significant risk."
A Chronic Issue?
Medical guidelines suggest the injections for people with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, due to the high risk of weight regain, the therapy is often life-long.
This opinion is supported by pharmaceutical companies, who state that the results "emphasize the long-term character of excess weight," akin to managing diseases like diabetes.
Patient Testimonies
People who have come off the medication explain a sudden return of cravings.
"It was like a trigger flipping and you're instantly extremely hungry," said an individual.
This difficulty is compounded if users have not developed sustainable lifestyle or habit modifications during therapy.
Widespread Interest
Figures show that millions of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Use is higher among females than men.
- The middle-aged demographic shows the highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
Finally, clinicians stress that while these medications are effective agents for shedding pounds, they are not a magic fix and maintained weight loss relies on integrated behavioural support.
