A recent study reveals that people who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover shed pounds far faster than those who stop conventional lifestyle regimens.
Published data in a leading health publication shows that while overweight people can lose about a fifth of their total mass while on the medication, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Users using these treatments should be aware of the potential of rapid weight regain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.
That rate of regain implies a return to starting weight in about a year and a half.
Analyzing Therapies
The research, which examined 37 of trials involving over 9,000 of patients, contrasted the outcomes of these new drugs with older methods.
Scientists emphasize that people who lose weight through diet and exercise usually experience a more gradual weight regain—around 100 grams monthly—once they finish.
The Reason for the Fast Rebound
Nutrition scientists suggest the mode of action of the injections accounts for the amplified regain.
These medications mimic a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing GLP-1 concentrations several times higher than normal might result in the system to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this hormone supplement leads to hunger is uncontrolled, making overeating far more likely."
A Chronic Condition?
Medical guidelines advise the injections for people with weight-linked health risks, alongside prescribed diet and exercise modifications.
Professionals contend that, given the significant potential of relapse, the therapy should be considered life-long.
This view is supported by pharmaceutical companies, who state that the results "underscore the chronic character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Experiences
People who have stopped the jabs report a sudden resurgence of appetite.
"It was like something that goes on and you're instantly starving," said an individual.
This difficulty is exacerbated if patients have not adopted sustainable lifestyle or habit modifications during therapy.
Significant Use
Figures indicate that millions of people in the UK have used these injections in the last 12 months, with interest being substantial.
- Adoption is greater among females compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
In conclusion, experts caution that while these medications are effective tools for weight loss, they are not a standalone cure and lasting health benefits relies on ongoing behavioural support.
