Fresh analysis reveals that patients who stop using popular slimming jabs like Mounjaro or Wegovy tend to recover shed pounds much more quickly than those who end traditional diet and exercise programs.
Published data in a major health publication shows that while overweight people frequently drop about a fifth of their body weight while using the jabs, the weight comes back at an average rate of 0.8 kg per month after stopping.
"Individuals using such treatments must be cognizant of the risk of rapid weight regain when the treatment concludes," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a return to starting mass within about 18 months.
Analyzing Treatments
The research, which reviewed 37 of studies involving thousands of patients, contrasted the outcomes of these new drugs with conventional dieting.
Researchers emphasize that people who lose weight through dieting typically have a slower creep back—perhaps 100 grams monthly—post-intervention.
The Reason for the Fast Regain
Experts believe the mechanism of the jabs is key to understanding the amplified regain.
These medications copy a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Long-term administration of the hormone concentrations several times higher than the body's typical production may cause the system to generate a reduced amount of its endogenous hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' means appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Issue?
The NHS suggest the injections for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Many experts contend that, considering the likelihood of weight regain, the therapy is often ongoing.
This opinion is reinforced by drug manufacturers, who note that the results "emphasize the long-term nature of obesity," comparing it to managing diseases like hypertension.
User Testimonies
People who have stopped the medication describe a powerful return of cravings.
"I experienced something flipping and you become starving," said an individual.
This difficulty is worsened if patients have not developed lasting lifestyle or habit modifications during therapy.
Widespread Adoption
Figures indicate that millions of people in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Use is greater among females compared to men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Ultimately, researchers emphasize that while GLP-1 drugs are powerful tools for weight loss, they are not a standalone fix and maintained weight loss likely depends on ongoing lifestyle support.
