Fresh analysis indicates that patients who stop using popular weight-loss injections like Wegovy and Mounjaro tend to recover lost weight far faster than those who halt traditional lifestyle plans.
Findings released in a major health publication points out that while overweight people frequently drop substantial amounts of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"Users purchasing such treatments must be aware of the risk of fast weight regain when the medication ends," cautioned expert Dr. Susan Jebb.
This pace of regain suggests a reversion to starting weight within about a year and a half.
Comparing Treatments
The analysis, which reviewed dozens of trials involving thousands of participants, compared the results of the injectable medications with other pills.
The team note that individuals who shed pounds through dieting generally see a more gradual weight regain—around 0.1 kg a month—once they finish.
The Reason for the Quick Rebound
Nutrition scientists propose the mode of action of the injections accounts for the amplified regain.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of GLP-1 levels several times higher than the body's typical production could lead to the system to produce less of its endogenous GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a nutrition expert.
"Stopping of this GLP-1 'fix' means hunger is no longer kept in check, making overeating much more probable."
An Ongoing Condition?
The NHS recommend the injections for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals argue that, due to the high risk of relapse, the therapy might need to be long-term.
This view is echoed by pharmaceutical companies, who state that the findings "emphasize the chronic character of obesity," comparing it to managing conditions like diabetes.
User Experiences
Individuals who have discontinued the medication report a sudden resurgence of cravings.
"It was like a switch flipping and you're instantly extremely hungry," recalled an individual.
This difficulty is worsened if patients have not established lasting lifestyle or habit changes during treatment.
Significant Adoption
Recent estimates suggest that a significant number of adults in the UK have used these injections in the past year, with interest continuing to grow.
- Use is greater among females than males.
- The middle-aged age group shows the greatest usage rates.
- Many access the medications through private healthcare rather than public health services.
Ultimately, experts stress that while these medications are effective agents for shedding pounds, they are not a standalone fix and maintained weight loss relies on ongoing lifestyle management.
