A recent study suggests that individuals who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who stop traditional lifestyle regimens.
Findings released in a major medical journal demonstrates that while obese people frequently drop a large proportion of their total mass while undergoing treatment, the weight is regained at an average rate of 0.8 kg per month upon discontinuation.
"Users buying these medications must be informed of the danger of rapid weight regain when the treatment is stopped," warns researcher Dr. Susan Jebb.
This pace of regain suggests a return to pre-treatment weight within about one and a half years.
Comparing Treatments
The study, which examined 37 of studies involving thousands of patients, compared the outcomes of GLP-1 agonists with other pills.
The team emphasize that individuals who lose weight through diet and exercise usually see a less rapid creep back—approximately 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Nutrition scientists propose the mode of action of the injections is key to understanding the heightened weight return.
GLP-1 drugs mimic a body's own chemical called GLP-1, which controls appetite.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous GLP-1, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' results in appetite is uncontrolled, making binge eating a significant risk."
A Chronic Issue?
Medical guidelines recommend the jabs for people with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
A number of clinicians contend that, due to the high risk of relapse, the treatment is often ongoing.
This opinion is reinforced by pharmaceutical companies, who say that the findings "highlight the long-term character of obesity," akin to managing diseases like high blood pressure.
User Accounts
Users who have come off the jabs report a powerful return of hunger.
"I experienced a switch that goes on and you become ravenous," said an individual.
The struggle is worsened if patients have not developed permanent lifestyle or habit changes during therapy.
Widespread Interest
Recent estimates indicate that a significant number of people in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Use is greater among females compared to men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers stress that while these medications are potent agents for shedding pounds, they are not a magic fix and maintained weight loss hinges on ongoing behavioural changes.
