A recent study reveals that people who come off new weight-loss injections like Wegovy and Mounjaro tend to recover shed pounds much more quickly than those who end conventional lifestyle plans.
Research printed in a leading health publication points out that while obese individuals can lose about a fifth of their body weight while using the jabs, the mass comes back at an average rate of 0.8 kg per month once they quit.
"People using these treatments must be informed of the potential of rapid weight regain when the therapy ends," warns researcher Dr. Susan Jebb.
Such speed of regain implies a return to original mass within about one and a half years.
Weighing Therapies
The study, which examined dozens of trials involving over 9,000 of participants, compared the effects of the injectable medications with other pills.
Researchers note that people who shed pounds through dieting generally have a less rapid weight regain—perhaps 100 grams monthly—once they finish.
Understanding the Fast Rebound
Nutrition scientists believe the mechanism of the drugs explains the amplified regain.
The injections mimic a body's own chemical called GLP-1, which helps regulate hunger.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement means hunger is no longer kept in check, making excessive eating much more probable."
An Ongoing Disease?
Medical guidelines suggest the jabs for people with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, due to the high risk of weight regain, the therapy might need to be ongoing.
This opinion is reinforced by drug manufacturers, who state that the results "emphasize the chronic nature of obesity," similar to managing conditions like high blood pressure.
Patient Accounts
People who have stopped the jabs explain a intense resurgence of hunger.
"I experienced a switch activating and you become starving," recalled an individual.
The struggle is exacerbated if patients have not adopted sustainable lifestyle or habit modifications during treatment.
Significant Use
Figures indicate that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with desire remaining high.
- Adoption is higher among females compared to men.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
Ultimately, experts emphasize that while the jabs are powerful agents for weight loss, they are not a permanent cure and lasting health benefits hinges on integrated lifestyle support.
