New research reveals that patients who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain reduced body mass far faster than those who end traditional lifestyle programs.
Published data in a major health publication points out that while obese people often shed a large proportion of their body weight while using the jabs, the weight comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"People using these drugs need to be informed of the risk of rapid rebound weight gain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to original weight within about a year and a half.
Analyzing Approaches
The research, which looked at 37 of trials involving thousands of participants, compared the effects of the injectable medications with conventional dieting.
Scientists emphasize that individuals who lose weight through diet and exercise generally experience a less rapid creep back—perhaps 100 grams monthly—post-intervention.
The Reason for the Fast Regain
Nutrition scientists believe the way of the jabs accounts for the heightened regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production could lead to the system to produce less of its endogenous GLP-1, and may also diminish responsiveness to its effects," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement leads to appetite is uncontrolled, making binge eating far more likely."
An Ongoing Issue?
Health authorities advise the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Many experts say that, given the likelihood of relapse, the treatment might need to be long-term.
This perspective is reinforced by pharmaceutical companies, who say that the findings "underscore the chronic character of excess weight," akin to managing diseases like diabetes.
Patient Experiences
People who have come off the medication explain a intense resurgence of appetite.
"It was like a trigger activating and you become ravenous," described an individual.
This difficulty is exacerbated if users have not established sustainable lifestyle or habit modifications during treatment.
Widespread Adoption
Recent estimates suggest that millions of people in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is higher among women compared to males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion access the medications through private healthcare rather than public health services.
In conclusion, experts caution that while these medications are powerful agents for weight loss, they are not a magic solution and maintained weight loss likely depends on ongoing lifestyle changes.
