New research indicates that patients who come off popular slimming jabs like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who stop conventional diet and exercise plans.
Findings released in a prominent health publication points out that while obese people can lose substantial amounts of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users buying such medications must be cognizant of the risk of fast weight regain when the therapy ends," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a reversion to pre-treatment weight in about 18 months.
Weighing Approaches
The study, which examined dozens of studies involving thousands of participants, compared the effects of these new drugs with other pills.
Scientists emphasize that people who shed pounds through dieting usually see a slower creep back—perhaps 100 grams monthly—post-intervention.
The Reason for the Fast Regain
Nutrition scientists believe the mode of action of the jabs is key to understanding the heightened regain.
These medications imitate a body's own chemical called GLP-1, which helps regulate appetite.
"Artificially providing the hormone concentrations several times higher than the body's typical production may cause the body to produce less of its endogenous GLP-1, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication means appetite is unsuppressed, making excessive eating far more likely."
An Ongoing Issue?
Medical guidelines suggest the injections for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians argue that, given the likelihood of weight regain, the treatment should be considered long-term.
This opinion is reinforced by drug manufacturers, who say that the results "emphasize the long-term character of excess weight," similar to managing diseases like diabetes.
Patient Testimonies
People who have stopped the medication report a intense resurgence of cravings.
"It felt as if something flipping and you become extremely hungry," said a patient.
This difficulty is exacerbated if users have not established sustainable lifestyle or habit modifications during treatment.
Growing Use
Recent estimates suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is more common among women compared to males.
- The 40s and 50s age group shows the highest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while the jabs are powerful tools for shedding pounds, they are not a magic solution and long-term success likely depends on integrated behavioural management.
