Fresh analysis reveals that patients who come off new weight-loss injections like Mounjaro or Wegovy tend to recover reduced body mass at a significantly accelerated pace than those who halt conventional diet and exercise plans.
Published data in a prominent medical journal shows that while obese individuals often shed a large proportion of their body weight while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"People buying such treatments must be cognizant of the potential of rapid rebound weight gain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to pre-treatment weight in about one and a half years.
Analyzing Treatments
The analysis, which reviewed dozens of studies involving over 9,000 of patients, contrasted the outcomes of these new drugs with conventional dieting.
The team note that individuals who shed pounds through dieting typically have a more gradual creep back—around 100 grams monthly—post-intervention.
Explaining the Quick Regain
Experts suggest the mechanism of the jabs accounts for the accelerated regain.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates hunger.
"Long-term administration of GLP-1 levels several times higher than the body's typical production might result in the body to produce less of its endogenous hormone, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication means hunger is unsuppressed, making excessive eating far more likely."
An Ongoing Condition?
The NHS suggest the jabs for people with obesity-related health risks, alongside recommended lifestyle changes.
Professionals say that, considering the significant potential of weight regain, the therapy might need to be life-long.
This opinion is echoed by drug manufacturers, who note that the results "emphasize the long-term character of excess weight," akin to managing conditions like high blood pressure.
Patient Accounts
People who have stopped the jabs explain a intense return of hunger.
"I experienced a switch that goes on and I was suddenly ravenous," recalled an individual.
This difficulty is worsened if users have not established sustainable dietary or behavioural modifications during therapy.
Significant Interest
Recent estimates indicate that millions of people in the UK have used these injections in the last 12 months, with demand being substantial.
- Adoption is more common among women compared to males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
Finally, researchers caution that while these medications are potent tools for shedding pounds, they are not a permanent cure and lasting health benefits relies on ongoing lifestyle management.
