A recent study indicates that people who come off new slimming jabs like Wegovy and Mounjaro can put back on lost weight far faster than those who end traditional lifestyle regimens.
Research printed in a leading health publication shows that while overweight individuals frequently drop a large proportion of their body weight while undergoing treatment, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such drugs need to be cognizant of the danger of quick weight regain when the therapy ends," warns expert Dr. Susan Jebb.
This pace of regain implies a return to pre-treatment weight in about a year and a half.
Comparing Treatments
The research, which reviewed dozens of trials involving thousands of patients, compared the outcomes of these new drugs with older methods.
Researchers note that individuals who lose weight through diet and exercise usually have a less rapid creep back—approximately 0.1 kg a month—after stopping.
Explaining the Quick Regain
Experts suggest the mode of action of the injections is key to understanding the heightened weight return.
The injections copy a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations several times higher than normal might result in the body to generate a reduced amount of its own natural hormone, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' results in hunger is no longer kept in check, making binge eating much more probable."
A Chronic Disease?
Medical guidelines advise the injections for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, considering the significant potential of relapse, the therapy might need to be life-long.
This perspective is reinforced by drug manufacturers, who note that the findings "emphasize the chronic character of excess weight," similar to managing diseases like diabetes.
Patient Accounts
Individuals who have discontinued the medication report a sudden return of cravings.
"It was like a switch flipping and you become starving," recalled an individual.
The struggle is worsened if users have not established permanent lifestyle or habit modifications during treatment.
Significant Adoption
Figures show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with interest being substantial.
- Use is more common among females than males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, clinicians caution that while GLP-1 drugs are potent tools for weight loss, they are not a magic solution and lasting health benefits likely depends on ongoing lifestyle changes.
