Fresh analysis reveals that people who discontinue new weight-loss injections like semaglutide or tirzepatide can put back on lost weight far faster than those who end traditional diet and exercise programs.
Findings released in a major health publication demonstrates that while overweight individuals often shed substantial amounts of their total mass while undergoing treatment, the weight returns at an estimated rate of 0.8 kg per month after stopping.
"Individuals using such medications need to be aware of the risk of quick weight regain when the medication concludes," stated researcher Dr. Susan Jebb.
That rate of regain means a return to starting mass in about one and a half years.
Comparing Approaches
The analysis, which reviewed dozens of studies involving over 9,000 of patients, contrasted the outcomes of the injectable medications with conventional dieting.
Researchers point out that individuals who lose weight through lifestyle changes alone usually experience a less rapid weight regain—around 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Doctors propose the mode of action of the drugs is key to understanding the amplified regain.
The injections imitate a natural hormone called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of the hormone levels several times higher than the body's typical production might result in the system to produce less of its own natural GLP-1, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement leads to hunger is uncontrolled, making excessive eating a significant risk."
An Ongoing Disease?
Health authorities suggest the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians argue that, due to the high risk of relapse, the therapy might need to be long-term.
This view is reinforced by drug manufacturers, who say that the findings "highlight the chronic nature of excess weight," comparing it to managing conditions like hypertension.
Patient Accounts
Individuals who have come off the jabs report a sudden return of hunger.
"It was like a trigger activating and you become extremely hungry," said one woman.
The struggle is compounded if users have not developed permanent lifestyle or habit modifications during therapy.
Growing Adoption
Recent estimates suggest that a significant number of people in the UK have used these injections in the last 12 months, with desire continuing to grow.
- Use is greater among women than men.
- The 40s and 50s age group shows the greatest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
Ultimately, researchers caution that while the jabs are potent agents for weight loss, they are not a standalone fix and maintained weight loss hinges on integrated lifestyle changes.
