New research indicates that individuals who stop using popular weight-loss injections like semaglutide or tirzepatide may regain lost weight much more quickly than those who stop traditional lifestyle programs.
Findings released in a major health publication shows that while overweight individuals can lose substantial amounts of their total mass while undergoing treatment, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals buying such drugs must be informed of the potential of rapid weight regain when the medication ends," cautioned expert Dr. Susan Jebb.
This pace of recovery implies a return to original weight in about one and a half years.
Comparing Treatments
The research, which looked at 37 of trials involving over 9,000 of participants, contrasted the results of GLP-1 agonists with conventional dieting.
Researchers emphasize that people who shed pounds through lifestyle changes alone typically experience a slower weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Nutrition scientists suggest the way of the jabs accounts for the accelerated regain.
These medications copy a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone levels several times higher than the body's typical production might result in the system to produce less of its endogenous hormone, and could reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' results in hunger is uncontrolled, making binge eating much more probable."
A Lifelong Issue?
Health authorities recommend the injections for people with obesity-related medical conditions, alongside recommended lifestyle changes.
Many experts contend that, considering the likelihood of weight regain, the therapy should be considered life-long.
This perspective is reinforced by drug manufacturers, who say that the results "underscore the chronic nature of obesity," comparing it to managing conditions like high blood pressure.
User Accounts
Users who have come off the medication report a sudden return of appetite.
"It was like a trigger flipping and you're instantly extremely hungry," described an individual.
The struggle is worsened if users have not established permanent dietary or behavioural modifications during therapy.
Widespread Use
Survey data indicate that a significant number of people in the UK have used these injections in the past year, with demand remaining high.
- Use is more common among females than males.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, researchers emphasize that while the jabs are powerful agents for shedding pounds, they are not a standalone solution and lasting health benefits likely depends on combined lifestyle changes.
