Users Coming Off Weight-Loss Injections Put On Weight Far More Rapidly Than People Using Diet and Exercise

A recent study reveals that individuals who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide can put back on lost weight far faster than those who end conventional lifestyle regimens.

Findings released in a major health publication demonstrates that while obese people often shed a large proportion of their total mass while undergoing treatment, the weight comes back at an estimated rate of nearly a kilo each month after stopping.

"Individuals using these treatments must be informed of the risk of rapid rebound weight gain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.

That rate of recovery means a return to original weight in about one and a half years.

Weighing Treatments

The study, which reviewed dozens of studies involving thousands of participants, compared the outcomes of these new drugs with other pills.

The team note that people who lose weight through lifestyle changes alone typically see a less rapid creep back—perhaps 0.1 kg a month—post-intervention.

The Reason for the Fast Rebound

Doctors propose the mode of action of the drugs explains the accelerated weight return.

These medications copy a body's own chemical called GLP-1, which helps regulate hunger.

"Artificially providing the hormone levels far above than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and may also lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.

"Stopping of this hormone supplement means hunger is no longer kept in check, making binge eating much more probable."

An Ongoing Issue?

Health authorities suggest the jabs for people with weight-linked health risks, alongside recommended diet and exercise modifications.

Professionals argue that, due to the high risk of relapse, the therapy should be considered ongoing.

This view is reinforced by pharmaceutical companies, who note that the results "highlight the chronic nature of excess weight," comparing it to managing conditions like diabetes.

Patient Experiences

People who have come off the medication explain a intense resurgence of appetite.

"It felt as if a trigger that goes on and you're instantly starving," described an individual.

The struggle is worsened if users have not adopted sustainable dietary or behavioural changes during treatment.

Significant Use

Figures indicate that millions of adults in the UK have tried these injections in the past year, with demand continuing to grow.

• Adoption is higher among women compared to males.
• The middle-aged demographic shows the greatest level of interest.
• A large proportion access the drugs through private prescriptions rather than public health services.

In conclusion, researchers stress that while these medications are effective agents for shedding pounds, they are not a standalone solution and long-term success hinges on integrated lifestyle management.
