Fresh analysis suggests that people who come off blockbuster weight-loss injections like Mounjaro or Wegovy may regain reduced body mass far faster than those who halt traditional diet and exercise plans.
Findings released in a prominent health publication shows that while overweight people frequently drop a large proportion of their body weight while on the medication, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"People buying such treatments must be informed of the risk of rapid rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
This pace of recovery suggests a return to starting mass within about one and a half years.
Analyzing Therapies
The research, which reviewed 37 of studies involving over 9,000 of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
The team emphasize that people who shed pounds through diet and exercise typically see a more gradual weight regain—approximately 100 grams monthly—post-intervention.
The Reason for the Rapid Regain
Nutrition scientists propose the way of the injections explains the heightened rebound.
GLP-1 drugs mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels several times higher than the body's typical production may cause the system to generate a reduced amount of its endogenous hormone, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' results in hunger is unsuppressed, making excessive eating much more probable."
A Chronic Disease?
Medical guidelines suggest the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Professionals say that, considering the high risk of relapse, the therapy is often ongoing.
This opinion is echoed by drug manufacturers, who note that the findings "highlight the long-term character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Accounts
Individuals who have stopped the medication report a intense return of cravings.
"I experienced a trigger that goes on and you're instantly starving," said an individual.
This difficulty is exacerbated if patients have not developed permanent dietary or behavioural changes during therapy.
Widespread Use
Recent estimates indicate that millions of people in the UK have used these injections in the last 12 months, with demand being substantial.
- Adoption is greater among females than men.
- The 40s and 50s demographic shows the greatest level of interest.
- Many obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts caution that while these medications are potent agents for weight loss, they are not a magic fix and long-term success relies on ongoing lifestyle changes.
