Fresh analysis reveals that patients who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who stop conventional diet and exercise regimens.
Findings released in a major medical journal shows that while overweight individuals can lose substantial amounts of their total mass while using the jabs, the weight is regained at an average rate of 0.8 kg per month after stopping.
"People buying these treatments should be informed of the danger of rapid rebound weight gain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
This pace of recovery suggests a reversion to starting mass in about 18 months.
Analyzing Therapies
The study, which examined 37 of trials involving thousands of patients, contrasted the results of these new drugs with older methods.
Scientists note that individuals who lose weight through lifestyle changes alone typically see a less rapid weight regain—approximately 0.1 kg a month—post-intervention.
The Reason for the Fast Regain
Experts believe the mode of action of the drugs explains the accelerated regain.
These medications copy a body's own chemical called GLP-1, which controls appetite.
"Artificially providing the hormone levels several times higher than the body's typical production could lead to the body to generate a reduced amount of its endogenous hormone, and may also reduce sensitivity to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication means hunger is uncontrolled, making binge eating much more probable."
An Ongoing Disease?
Medical guidelines recommend the jabs for people with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians contend that, given the significant potential of relapse, the therapy should be considered life-long.
This perspective is reinforced by pharmaceutical companies, who state that the results "underscore the persistent nature of obesity," akin to managing diseases like diabetes.
Patient Testimonies
Users who have come off the medication explain a intense return of cravings.
"It felt as if a trigger activating and I was suddenly starving," recalled a patient.
This challenge is compounded if patients have not established lasting lifestyle or habit modifications during treatment.
Widespread Adoption
Figures indicate that a significant number of people in the UK have used these injections in the last 12 months, with desire being substantial.
- Use is greater among women compared to men.
- The 40s and 50s age group shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while these medications are potent agents for weight loss, they are not a standalone fix and lasting health benefits relies on integrated behavioural changes.
