Fresh analysis suggests that individuals who discontinue popular weight-loss injections like semaglutide or tirzepatide may regain reduced body mass far faster than those who halt traditional lifestyle regimens.
Findings released in a major health publication demonstrates that while obese individuals frequently drop about a fifth of their total mass while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month after stopping.
"People purchasing these medications need to be informed of the danger of rapid weight regain when the treatment is stopped," stated researcher Dr. Susan Jebb.
That rate of regain implies a reversion to starting weight in about one and a half years.
Comparing Approaches
The research, which reviewed dozens of studies involving thousands of participants, compared the outcomes of these new drugs with conventional dieting.
Researchers point out that individuals who shed pounds through diet and exercise usually have a more gradual weight regain—perhaps 0.1 kg a month—after stopping.
The Reason for the Fast Regain
Doctors suggest the mechanism of the drugs accounts for the heightened regain.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone levels several times higher than normal may cause the body to generate a reduced amount of its endogenous GLP-1, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication leads to appetite is no longer kept in check, making binge eating a significant risk."
A Lifelong Disease?
Health authorities advise the jabs for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts argue that, due to the high risk of weight regain, the therapy might need to be life-long.
This perspective is supported by drug manufacturers, who state that the results "emphasize the persistent character of excess weight," akin to managing diseases like high blood pressure.
Patient Experiences
Individuals who have discontinued the medication describe a intense return of cravings.
"It was like something activating and you're instantly extremely hungry," described an individual.
This challenge is compounded if users have not developed lasting lifestyle or habit modifications during treatment.
Significant Adoption
Figures show that millions of people in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.
- Use is higher among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Ultimately, experts emphasize that while GLP-1 drugs are effective agents for weight loss, they are not a magic fix and maintained weight loss likely depends on ongoing lifestyle support.
