Fresh analysis suggests that individuals who come off new weight-loss injections like Wegovy and Mounjaro may regain shed pounds far faster than those who stop traditional diet and exercise regimens.
Research printed in a major health publication points out that while obese individuals can lose substantial amounts of their total mass while using the jabs, the mass returns at an average rate of 0.8 kg per month after stopping.
"People using such medications must be informed of the risk of fast weight regain when the medication concludes," stated expert Dr. Susan Jebb.
That rate of regain implies a return to starting weight within about a year and a half.
Weighing Therapies
The research, which examined dozens of trials involving over 9,000 of participants, compared the outcomes of the injectable medications with other pills.
Scientists emphasize that individuals who lose weight through dieting typically see a less rapid creep back—around 100 grams monthly—after stopping.
The Reason for the Quick Regain
Nutrition scientists believe the way of the jabs is key to understanding the heightened weight return.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production may cause the body to generate a reduced amount of its own natural GLP-1, and could reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this medication means hunger is unsuppressed, making overeating a significant risk."
An Ongoing Disease?
Medical guidelines suggest the injections for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals contend that, considering the significant potential of weight regain, the therapy is often ongoing.
This view is reinforced by pharmaceutical companies, who state that the results "underscore the chronic nature of excess weight," comparing it to managing diseases like hypertension.
Patient Accounts
Individuals who have stopped the medication explain a intense return of cravings.
"It felt as if a trigger flipping and you're instantly starving," described one woman.
The struggle is compounded if patients have not developed permanent lifestyle or habit modifications during therapy.
Widespread Interest
Recent estimates suggest that a significant number of people in the UK have used these injections in the last 12 months, with demand continuing to grow.
- Use is greater among females than males.
- The middle-aged age group shows the greatest usage rates.
- Many obtain the medications through private prescriptions rather than public health services.
Ultimately, experts emphasize that while the jabs are potent tools for shedding pounds, they are not a magic fix and long-term success hinges on combined lifestyle support.
