A recent study suggests that patients who come off popular weight-loss injections like semaglutide or tirzepatide may regain shed pounds much more quickly than those who stop conventional lifestyle regimens.
Published data in a major medical journal shows that while overweight individuals frequently drop a large proportion of their body weight while on the medication, the mass comes back at an estimated rate of 0.8 kg per month once they quit.
"People purchasing such treatments need to be informed of the potential of fast rebound weight gain when the treatment ends," stated expert Dr. Susan Jebb.
This pace of recovery suggests a reversion to pre-treatment weight in about 18 months.
Analyzing Treatments
The analysis, which looked at dozens of trials involving over 9,000 of patients, compared the results of these new drugs with other pills.
Scientists point out that people who lose weight through lifestyle changes alone usually have a more gradual weight regain—around 100 grams monthly—once they finish.
Understanding the Fast Rebound
Experts propose the mechanism of the injections explains the amplified weight return.
GLP-1 drugs mimic a natural hormone called GLP-1, which controls feelings of fullness.
"Artificially providing the hormone concentrations several times higher than normal may cause the system to produce less of its own natural GLP-1, and could reduce sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement results in hunger is unsuppressed, making overeating a significant risk."
An Ongoing Condition?
The NHS advise the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Professionals contend that, due to the significant potential of relapse, the treatment might need to be life-long.
This perspective is echoed by pharmaceutical companies, who say that the results "highlight the persistent character of excess weight," comparing it to managing diseases like hypertension.
User Accounts
Individuals who have come off the medication report a intense return of hunger.
"I experienced something activating and I was suddenly starving," recalled one woman.
The struggle is compounded if individuals have not adopted sustainable lifestyle or habit modifications during therapy.
Widespread Interest
Survey data suggest that a significant number of people in the UK have tried weight-loss jabs in the past year, with interest continuing to grow.
- Use is greater among females compared to men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
Finally, experts caution that while these medications are effective tools for shedding pounds, they are not a standalone cure and lasting health benefits likely depends on integrated lifestyle support.
