Patients Coming Off Anti-Obesity Injections Put On Pounds Far More Rapidly Than People Using Diet and Exercise

Fresh analysis suggests that individuals who come off popular slimming jabs like Mounjaro or Wegovy may regain reduced body mass at a significantly accelerated pace than those who end conventional lifestyle regimens.

Findings released in a leading medical journal shows that while obese people often shed substantial amounts of their total mass while on the medication, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.

"Users using these drugs need to be cognizant of the risk of fast rebound weight gain when the therapy ends," cautioned researcher Dr. Susan Jebb.

This pace of regain means a return to pre-treatment mass within about 18 months.

Comparing Therapies

The analysis, which reviewed 37 of trials involving over 9,000 of participants, compared the outcomes of the injectable medications with conventional dieting.

Scientists point out that people who lose weight through diet and exercise generally experience a more gradual creep back—perhaps 0.1 kg a month—after stopping.

Explaining the Rapid Rebound

Doctors believe the mechanism of the jabs is key to understanding the heightened regain.

These medications imitate a body's own chemical called glucagon-like peptide-1, which controls hunger.

"Artificially providing the hormone levels several times higher than normal may cause the body to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a nutrition expert.

"Discontinuation of this GLP-1 'fix' results in appetite is no longer kept in check, making excessive eating far more likely."

An Ongoing Issue?

The NHS recommend the jabs for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.

A number of clinicians argue that, due to the likelihood of relapse, the treatment might need to be long-term.

This opinion is reinforced by pharmaceutical companies, who note that the results "emphasize the persistent character of excess weight," comparing it to managing conditions like diabetes.

Patient Testimonies

Individuals who have stopped the jabs report a intense return of hunger.

"I experienced a switch flipping and I was suddenly ravenous," recalled a patient.

This difficulty is worsened if patients have not adopted lasting lifestyle or habit modifications during therapy.

Significant Interest

Recent estimates suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.

• Use is more common among women than men.
• The 40s and 50s age group shows the highest level of interest.
• A large proportion obtain the drugs through private healthcare rather than the NHS.

In conclusion, experts emphasize that while these medications are powerful tools for shedding pounds, they are not a permanent solution and lasting health benefits hinges on ongoing behavioural management.
