A recent study suggests that patients who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy may regain shed pounds far faster than those who end conventional lifestyle regimens.
Findings released in a leading medical journal points out that while overweight individuals can lose about a fifth of their total mass while undergoing treatment, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"People purchasing such medications should be aware of the potential of rapid weight regain when the therapy ends," cautioned expert Dr. Susan Jebb.
Such speed of recovery means a return to pre-treatment weight in about 18 months.
Comparing Approaches
The study, which reviewed dozens of studies involving over 9,000 of participants, contrasted the effects of these new drugs with other pills.
The team note that people who shed pounds through dieting usually see a slower weight regain—around 0.1 kg a month—once they finish.
Explaining the Rapid Regain
Experts suggest the mode of action of the jabs accounts for the heightened regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of the hormone concentrations far above than normal could lead to the body to generate a reduced amount of its own natural hormone, and could reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' leads to appetite is unsuppressed, making overeating much more probable."
A Chronic Issue?
Health authorities suggest the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
Many experts contend that, given the likelihood of weight regain, the therapy might need to be long-term.
This opinion is supported by pharmaceutical companies, who say that the results "highlight the chronic nature of obesity," akin to managing diseases like high blood pressure.
User Testimonies
Individuals who have discontinued the jabs explain a powerful return of cravings.
"It felt as if a switch that goes on and you become ravenous," said one woman.
This challenge is compounded if individuals have not developed lasting lifestyle or habit modifications during treatment.
Significant Adoption
Recent estimates suggest that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Use is higher among females than men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, experts emphasize that while GLP-1 drugs are potent tools for shedding pounds, they are not a magic solution and maintained weight loss relies on ongoing lifestyle management.
