Fresh analysis reveals that people who come off new weight-loss injections like semaglutide or tirzepatide may regain shed pounds far faster than those who halt conventional diet and exercise regimens.
Findings released in a leading health publication points out that while overweight people can lose substantial amounts of their body weight while using the jabs, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Users using such treatments need to be cognizant of the potential of rapid weight regain when the medication ends," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to original mass within about a year and a half.
Analyzing Therapies
The study, which examined 37 of studies involving over 9,000 of participants, contrasted the outcomes of the injectable medications with other pills.
Scientists emphasize that people who lose weight through lifestyle changes alone generally experience a more gradual creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Experts believe the mode of action of the drugs explains the accelerated regain.
These medications imitate a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Long-term administration of GLP-1 levels far above than normal could lead to the body to generate a reduced amount of its endogenous hormone, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this hormone supplement results in appetite is unsuppressed, making excessive eating much more probable."
An Ongoing Condition?
Health authorities advise the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, given the significant potential of relapse, the therapy should be considered ongoing.
This perspective is supported by drug manufacturers, who say that the findings "underscore the chronic nature of obesity," comparing it to managing diseases like diabetes.
Patient Experiences
Individuals who have come off the jabs describe a intense return of hunger.
"It felt as if something activating and I was suddenly starving," described one woman.
This difficulty is compounded if users have not developed sustainable lifestyle or habit modifications during treatment.
Widespread Interest
Figures suggest that a significant number of people in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Use is more common among females than men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than the NHS.
Ultimately, clinicians caution that while the jabs are powerful tools for weight loss, they are not a permanent cure and lasting health benefits likely depends on integrated behavioural changes.
