Fresh analysis suggests that people who discontinue popular weight-loss injections like semaglutide or tirzepatide may regain shed pounds much more quickly than those who end conventional diet and exercise plans.
Published data in a leading medical journal shows that while obese people frequently drop a large proportion of their body weight while using the jabs, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing these treatments should be informed of the danger of fast rebound weight gain when the medication ends," warns researcher Dr. Susan Jebb.
Such speed of recovery means a return to original weight in about a year and a half.
Analyzing Treatments
The analysis, which reviewed dozens of studies involving thousands of participants, contrasted the effects of these new drugs with other pills.
Scientists point out that individuals who lose weight through lifestyle changes alone generally see a slower weight regain—approximately 100 grams monthly—post-intervention.
Explaining the Fast Regain
Nutrition scientists believe the mode of action of the injections is key to understanding the amplified regain.
These medications copy a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing the hormone concentrations far above than normal might result in the system to generate a reduced amount of its own natural GLP-1, and could lessen responsiveness to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication means hunger is unsuppressed, making overeating far more likely."
An Ongoing Condition?
The NHS advise the injections for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts contend that, given the likelihood of weight regain, the treatment is often life-long.
This opinion is reinforced by pharmaceutical companies, who note that the results "underscore the long-term character of excess weight," akin to managing conditions like diabetes.
User Experiences
Individuals who have stopped the medication describe a intense return of appetite.
"It felt as if something that goes on and you become ravenous," recalled an individual.
The struggle is worsened if patients have not adopted lasting lifestyle or habit modifications during treatment.
Significant Adoption
Recent estimates show that millions of adults in the UK have used these injections in the past year, with desire being substantial.
- Adoption is greater among women compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, experts stress that while these medications are powerful agents for weight loss, they are not a standalone solution and long-term success likely depends on integrated lifestyle changes.
