New research suggests that people who discontinue new weight-loss injections like Mounjaro or Wegovy can put back on lost weight far faster than those who halt traditional diet and exercise plans.
Research printed in a leading health publication demonstrates that while overweight individuals can lose substantial amounts of their total mass while on the medication, the mass returns at an average rate of nearly a kilo each month after stopping.
"Individuals purchasing such treatments should be informed of the risk of fast weight regain when the treatment ends," stated expert Dr. Susan Jebb.
That rate of recovery suggests a return to original weight within about a year and a half.
Comparing Therapies
The analysis, which examined dozens of studies involving thousands of patients, contrasted the results of these new drugs with conventional dieting.
Researchers point out that people who lose weight through diet and exercise typically see a less rapid weight regain—approximately 100 grams monthly—after stopping.
The Reason for the Fast Rebound
Doctors suggest the way of the drugs accounts for the heightened regain.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing GLP-1 concentrations far above than the body's typical production might result in the body to produce less of its own natural hormone, and could diminish responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this hormone supplement leads to appetite is uncontrolled, making overeating much more probable."
A Lifelong Issue?
Health authorities advise the jabs for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians contend that, given the significant potential of weight regain, the therapy is often life-long.
This view is reinforced by drug manufacturers, who say that the findings "emphasize the chronic character of excess weight," akin to managing diseases like high blood pressure.
Patient Experiences
People who have stopped the jabs report a sudden resurgence of cravings.
"It felt as if a switch flipping and you're instantly ravenous," recalled a patient.
This difficulty is compounded if users have not developed permanent lifestyle or habit modifications during therapy.
Growing Adoption
Survey data show that millions of people in the UK have used these injections in the last 12 months, with interest being substantial.
- Adoption is higher among females than men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
In conclusion, experts caution that while the jabs are effective tools for weight loss, they are not a magic cure and maintained weight loss relies on ongoing lifestyle management.
