A recent study suggests that individuals who come off popular weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass far faster than those who stop conventional diet and exercise regimens.
Published data in a leading medical journal points out that while overweight individuals can lose substantial amounts of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Users purchasing these medications must be informed of the potential of fast weight regain when the medication ends," cautioned researcher Dr. Susan Jebb.
Such speed of regain suggests a return to original mass within about 18 months.
Comparing Approaches
The research, which examined 37 of studies involving thousands of patients, contrasted the outcomes of the injectable medications with older methods.
Scientists note that individuals who shed pounds through dieting generally have a slower creep back—perhaps 0.1 kg a month—after stopping.
Understanding the Fast Rebound
Nutrition scientists believe the mechanism of the injections accounts for the amplified regain.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing the hormone levels several times higher than the body's typical production might result in the system to produce less of its endogenous GLP-1, and may also diminish responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement results in hunger is unsuppressed, making excessive eating a significant risk."
A Chronic Condition?
Medical guidelines suggest the injections for people with obesity-related health risks, alongside recommended diet and exercise modifications.
Professionals argue that, given the high risk of relapse, the therapy should be considered ongoing.
This view is reinforced by pharmaceutical companies, who note that the findings "highlight the long-term nature of excess weight," akin to managing diseases like hypertension.
Patient Accounts
Individuals who have discontinued the medication report a sudden resurgence of hunger.
"It was like a trigger activating and you become extremely hungry," said an individual.
The struggle is worsened if users have not developed permanent lifestyle or habit changes during treatment.
Widespread Adoption
Survey data indicate that millions of people in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Use is higher among females than males.
- The middle-aged demographic shows the greatest usage rates.
- Many access the medications through private healthcare rather than the NHS.
In conclusion, clinicians caution that while these medications are potent agents for shedding pounds, they are not a permanent cure and long-term success hinges on ongoing behavioural changes.
