New research reveals that patients who stop using blockbuster weight-loss injections like semaglutide or tirzepatide may regain reduced body mass far faster than those who halt traditional diet and exercise programs.
Published data in a leading medical journal points out that while obese people often shed substantial amounts of their total mass while undergoing treatment, the mass is regained at an estimated rate of nearly a kilo each month once they quit.
"Users buying these treatments should be informed of the danger of rapid rebound weight gain when the therapy concludes," stated expert Dr. Susan Jebb.
This pace of recovery implies a return to pre-treatment mass within about 18 months.
Weighing Therapies
The research, which reviewed 37 of studies involving thousands of participants, compared the results of GLP-1 agonists with other pills.
The team point out that individuals who shed pounds through lifestyle changes alone typically have a less rapid creep back—perhaps 0.1 kg a month—once they finish.
Understanding the Fast Rebound
Experts suggest the mechanism of the drugs accounts for the heightened rebound.
The injections mimic a body's own chemical called GLP-1, which helps regulate hunger.
"Sustained high doses of the hormone concentrations several times higher than normal may cause the system to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication results in hunger is uncontrolled, making excessive eating much more probable."
A Lifelong Disease?
Health authorities recommend the injections for people with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals contend that, given the likelihood of relapse, the treatment should be considered long-term.
This perspective is supported by drug manufacturers, who state that the results "highlight the long-term character of excess weight," comparing it to managing diseases like hypertension.
Patient Accounts
Individuals who have come off the jabs describe a sudden resurgence of cravings.
"I experienced a switch flipping and you become ravenous," recalled an individual.
This difficulty is exacerbated if individuals have not developed permanent lifestyle or habit modifications during therapy.
Significant Use
Recent estimates indicate that a significant number of people in the UK have tried these injections in the last 12 months, with desire remaining high.
- Adoption is greater among females than men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
In conclusion, experts emphasize that while these medications are potent agents for weight loss, they are not a standalone fix and lasting health benefits likely depends on combined lifestyle changes.
