Fresh analysis indicates that people who stop using blockbuster slimming jabs like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who end conventional diet and exercise plans.
Published data in a major medical journal points out that while obese people often shed substantial amounts of their body weight while on the medication, the mass comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"Users purchasing these drugs need to be informed of the danger of rapid rebound weight gain when the treatment concludes," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to pre-treatment weight in about one and a half years.
Analyzing Approaches
The research, which reviewed dozens of trials involving thousands of patients, compared the effects of GLP-1 agonists with other pills.
The team point out that people who shed pounds through dieting typically have a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Nutrition scientists suggest the way of the drugs is key to understanding the accelerated weight return.
These medications imitate a body's own chemical called GLP-1, which moderates feelings of fullness.
"Long-term administration of the hormone levels far above than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and may also diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this medication leads to hunger is no longer kept in check, making overeating much more probable."
An Ongoing Issue?
Health authorities advise the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians say that, given the high risk of relapse, the treatment might need to be life-long.
This perspective is supported by pharmaceutical companies, who state that the findings "emphasize the long-term nature of excess weight," akin to managing diseases like high blood pressure.
Patient Accounts
Individuals who have come off the medication describe a powerful return of cravings.
"I experienced something activating and I was suddenly extremely hungry," recalled a patient.
This challenge is worsened if users have not developed permanent lifestyle or habit modifications during therapy.
Significant Interest
Recent estimates show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is higher among females than men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, experts stress that while the jabs are potent tools for shedding pounds, they are not a permanent solution and lasting health benefits likely depends on ongoing lifestyle support.
