A recent study indicates that people who discontinue popular weight-loss injections like Wegovy and Mounjaro can put back on shed pounds much more quickly than those who halt traditional lifestyle programs.
Published data in a major health publication points out that while obese people often shed substantial amounts of their total mass while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month after stopping.
"Users purchasing these drugs must be aware of the danger of rapid weight regain when the treatment is stopped," warns expert Dr. Susan Jebb.
This pace of recovery suggests a return to original weight within about 18 months.
Comparing Approaches
The research, which reviewed dozens of studies involving over 9,000 of participants, compared the outcomes of GLP-1 agonists with other pills.
Scientists emphasize that people who shed pounds through dieting usually experience a less rapid weight regain—approximately 100 grams monthly—post-intervention.
Explaining the Rapid Rebound
Nutrition scientists believe the way of the injections explains the accelerated rebound.
GLP-1 drugs imitate a natural hormone called GLP-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its own natural GLP-1, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement means hunger is uncontrolled, making excessive eating a significant risk."
A Chronic Disease?
The NHS recommend the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals contend that, due to the significant potential of weight regain, the treatment might need to be life-long.
This opinion is supported by drug manufacturers, who state that the findings "highlight the chronic nature of excess weight," akin to managing diseases like high blood pressure.
User Accounts
People who have come off the medication explain a intense resurgence of cravings.
"It was like a switch activating and you become extremely hungry," recalled one woman.
This challenge is compounded if users have not developed permanent dietary or behavioural changes during therapy.
Widespread Adoption
Survey data suggest that a significant number of people in the UK have used these injections in the past year, with interest remaining high.
- Use is greater among women compared to males.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
In conclusion, researchers stress that while GLP-1 drugs are effective tools for shedding pounds, they are not a permanent cure and maintained weight loss likely depends on ongoing lifestyle support.
