Fresh analysis reveals that individuals who discontinue new weight-loss injections like Mounjaro or Wegovy tend to recover lost weight much more quickly than those who stop traditional lifestyle plans.
Research printed in a leading medical journal demonstrates that while obese individuals often shed substantial amounts of their body weight while undergoing treatment, the weight returns at an estimated rate of 0.8 kg per month once they quit.
"People using such medications should be cognizant of the danger of fast rebound weight gain when the treatment ends," stated expert Dr. Susan Jebb.
That rate of recovery implies a return to original weight within about a year and a half.
Weighing Therapies
The study, which examined 37 of trials involving over 9,000 of patients, compared the outcomes of GLP-1 agonists with older methods.
Scientists note that people who lose weight through diet and exercise generally see a more gradual weight regain—approximately 100 grams monthly—after stopping.
Understanding the Fast Regain
Experts propose the way of the jabs is key to understanding the amplified regain.
The injections mimic a natural hormone called glucagon-like peptide-1, which controls hunger.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement means hunger is no longer kept in check, making overeating much more probable."
A Chronic Condition?
The NHS recommend the injections for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Professionals say that, due to the likelihood of weight regain, the therapy is often long-term.
This opinion is reinforced by pharmaceutical companies, who say that the findings "emphasize the long-term character of excess weight," similar to managing conditions like hypertension.
User Accounts
Users who have stopped the jabs report a powerful return of cravings.
"I experienced something activating and you become starving," described one woman.
The struggle is exacerbated if users have not developed permanent dietary or behavioural changes during therapy.
Significant 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 remaining high.
- Use is more common among females compared to men.
- The 40s and 50s demographic shows the greatest usage rates.
- Many access the drugs through private healthcare rather than the NHS.
Ultimately, experts stress that while these medications are powerful agents for weight loss, they are not a permanent fix and lasting health benefits likely depends on integrated lifestyle management.
