Fresh analysis reveals that individuals who discontinue blockbuster slimming jabs like Wegovy and Mounjaro can put back on reduced body mass much more quickly than those who end traditional lifestyle plans.
Research printed in a leading medical journal points out that while obese people frequently drop about a fifth of their body weight while on the medication, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such treatments need to be informed of the risk of rapid rebound weight gain when the medication concludes," warns expert Dr. Susan Jebb.
That rate of recovery implies a return to pre-treatment weight within about a year and a half.
Comparing Therapies
The analysis, which looked at dozens of trials involving thousands of patients, compared the outcomes of these new drugs with older methods.
Researchers emphasize that people who lose weight through diet and exercise generally experience a less rapid creep back—perhaps 100 grams monthly—once they finish.
Understanding the Quick Regain
Nutrition scientists suggest the mode of action of the injections is key to understanding the amplified weight return.
GLP-1 drugs copy a body's own chemical called GLP-1, which controls feelings of fullness.
"Long-term administration of the hormone levels several times higher than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and could diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in hunger is uncontrolled, making overeating a significant risk."
A Chronic Condition?
Health authorities recommend the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
A number of clinicians argue that, considering the likelihood of relapse, the therapy should be considered life-long.
This opinion is reinforced by pharmaceutical companies, who note that the results "underscore the chronic nature of excess weight," similar to managing conditions like diabetes.
User Experiences
People who have come off the jabs explain a powerful resurgence of hunger.
"It felt as if a trigger that goes on and you become ravenous," said one woman.
This challenge is worsened if patients have not developed sustainable lifestyle or habit modifications during therapy.
Widespread Use
Recent estimates show that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with interest continuing to grow.
- Adoption is higher among women than men.
- The middle-aged age group shows the greatest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, clinicians caution that while GLP-1 drugs are potent agents for weight loss, they are not a magic fix and long-term success likely depends on combined behavioural changes.
