A recent study suggests that individuals who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who end traditional diet and exercise programs.
Research printed in a prominent health publication demonstrates that while overweight individuals frequently drop a large proportion of their total mass while on the medication, the weight is regained at an average rate of 0.8 kg per month once they quit.
"Individuals using such medications should be informed of the potential of quick rebound weight gain when the medication is stopped," warns researcher Dr. Susan Jebb.
Such speed of recovery suggests a reversion to original mass in about 18 months.
Analyzing Treatments
The research, which reviewed dozens of studies involving over 9,000 of patients, contrasted the results of GLP-1 agonists with conventional dieting.
The team note that individuals who shed pounds through diet and exercise generally see a less rapid weight regain—around 100 grams monthly—after stopping.
Understanding the Fast Regain
Nutrition scientists suggest the mode of action of the jabs explains the accelerated regain.
The injections imitate a body's own chemical called GLP-1, which controls feelings of fullness.
"Long-term administration of GLP-1 levels several times higher than the body's typical production might result in the body to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication means appetite is no longer kept in check, making overeating much more probable."
An Ongoing Condition?
The NHS suggest the jabs for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.
Many experts contend that, given the significant potential of weight regain, the therapy might need to be ongoing.
This opinion is echoed by pharmaceutical companies, who note that the results "underscore the persistent character of excess weight," akin to managing diseases like diabetes.
User Accounts
Individuals who have come off the medication explain a sudden resurgence of cravings.
"It was like a trigger flipping and you become starving," recalled an individual.
This challenge is compounded if patients have not developed sustainable dietary or behavioural modifications during treatment.
Widespread Use
Figures suggest that a significant number of people in the UK have tried these injections in the last 12 months, with demand remaining high.
- Use is higher among women compared to men.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while these medications are potent tools for shedding pounds, they are not a magic fix and maintained weight loss relies on ongoing lifestyle support.
