Fresh analysis reveals that people who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide may regain lost weight much more quickly than those who halt traditional lifestyle plans.
Findings released in a leading medical journal shows that while overweight people frequently drop about a fifth of their body weight while on the medication, the weight comes back at an average rate of 0.8 kg per month after stopping.
"People using these drugs must be aware of the risk of fast rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
This pace of regain implies a reversion to original mass within about 18 months.
Comparing Treatments
The research, which examined 37 of studies involving thousands of patients, compared the results of GLP-1 agonists with conventional dieting.
The team note that people who shed pounds through diet and exercise usually experience a less rapid creep back—approximately 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Nutrition scientists propose the mechanism of the jabs explains the amplified weight return.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of the hormone concentrations far above than normal may cause the body to generate a reduced amount of its own natural hormone, and may also lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication leads to hunger is unsuppressed, making overeating a significant risk."
A Lifelong Issue?
Health authorities suggest the jabs for individuals with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts contend that, given the high risk of weight regain, the treatment should be considered life-long.
This perspective is echoed by drug manufacturers, who say that the findings "highlight the long-term character of obesity," comparing it to managing diseases like hypertension.
User Accounts
Users who have discontinued the medication explain a powerful resurgence of cravings.
"It was like something flipping and I was suddenly extremely hungry," described an individual.
This difficulty is exacerbated if individuals have not adopted permanent lifestyle or habit modifications during therapy.
Widespread Adoption
Figures suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Use is higher among females than men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, clinicians caution that while the jabs are potent tools for shedding pounds, they are not a permanent cure and maintained weight loss hinges on integrated lifestyle management.
