Fresh analysis indicates that individuals who come off blockbuster slimming jabs like Wegovy and Mounjaro tend to recover shed pounds at a significantly accelerated pace than those who end traditional diet and exercise programs.
Findings released in a major medical journal demonstrates that while overweight people often shed substantial amounts of their total mass while on the medication, the mass is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing such drugs need to be aware of the risk of fast rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to starting weight in about a year and a half.
Comparing Approaches
The research, which examined 37 of studies involving over 9,000 of patients, compared the outcomes of GLP-1 agonists with other pills.
Researchers point out that individuals who lose weight through lifestyle changes alone generally have a more gradual creep back—perhaps 0.1 kg a month—once they finish.
Understanding the Fast Rebound
Experts propose the mechanism of the injections is key to understanding the heightened regain.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Long-term administration of the hormone levels several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement means hunger is unsuppressed, making excessive eating much more probable."
An Ongoing Disease?
Medical guidelines recommend the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Many experts argue that, due to the likelihood of relapse, the therapy is often ongoing.
This perspective is reinforced by pharmaceutical companies, who state that the results "underscore the chronic character of obesity," similar to managing diseases like hypertension.
Patient Accounts
People who have stopped the medication describe a intense resurgence of hunger.
"It felt as if a switch that goes on and you become extremely hungry," recalled an individual.
This difficulty is compounded if users have not adopted lasting lifestyle or habit modifications during treatment.
Growing Interest
Figures suggest that millions of adults in the UK have tried weight-loss jabs in the past year, with demand being substantial.
- Use is more common among females than men.
- The middle-aged age group shows the highest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians caution that while these medications are effective tools for shedding pounds, they are not a magic cure and maintained weight loss relies on ongoing behavioural support.
