Fresh analysis reveals that patients who discontinue blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who stop traditional diet and exercise regimens.
Research printed in a prominent medical journal points out that while obese people can lose substantial amounts of their total mass while using the jabs, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"Individuals buying such drugs must be cognizant of the risk of fast weight regain when the medication concludes," warns researcher Dr. Susan Jebb.
Such speed of recovery means a reversion to original weight within about a year and a half.
Weighing Treatments
The study, which examined dozens of studies involving thousands of participants, contrasted the results of these new drugs with conventional dieting.
Researchers note that people who shed pounds through dieting usually see a slower weight regain—around 100 grams monthly—after stopping.
The Reason for the Fast Regain
Nutrition scientists believe the mechanism of the injections accounts for the accelerated rebound.
GLP-1 drugs imitate a natural hormone called GLP-1, which controls hunger.
"Sustained high doses of the hormone concentrations several times higher than normal could lead to the body to produce less of its endogenous hormone, and could diminish responsiveness to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating a significant risk."
An Ongoing Disease?
Medical guidelines recommend the jabs for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals contend that, given the significant potential of weight regain, the therapy is often life-long.
This perspective is reinforced by drug manufacturers, who say that the results "underscore the long-term nature of excess weight," similar to managing conditions like high blood pressure.
Patient Accounts
People who have come off the medication describe a powerful resurgence of cravings.
"It was like something activating and you become ravenous," recalled one woman.
This challenge is worsened if users have not established lasting dietary or behavioural modifications during treatment.
Significant Interest
Figures show that a significant number of people in the UK have used these injections in the last 12 months, with demand being substantial.
- Use is more common among females compared to men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, experts caution that while these medications are effective agents for weight loss, they are not a permanent cure and lasting health benefits relies on ongoing lifestyle support.
