A recent study reveals that patients who come off new weight-loss injections like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who end conventional diet and exercise regimens.
Research printed in a prominent health publication points out that while obese individuals can lose about a fifth of their body weight while on the medication, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"People buying such drugs must be informed of the potential of rapid rebound weight gain when the medication is stopped," cautioned researcher Dr. Susan Jebb.
That rate of recovery means a return to starting weight within about 18 months.
Analyzing Therapies
The analysis, which examined 37 of studies involving thousands of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers point out that individuals who lose weight through diet and exercise generally see a slower weight regain—perhaps 100 grams monthly—after stopping.
The Reason for the Rapid Regain
Nutrition scientists believe the way of the drugs accounts for the heightened regain.
The injections mimic a body's own chemical called GLP-1, which controls feelings of fullness.
"Long-term administration of the hormone levels far above than the body's typical production may cause the system to produce less of its own natural GLP-1, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making overeating far more likely."
A Chronic Condition?
Medical guidelines recommend the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Many experts argue that, due to the likelihood of relapse, the therapy is often long-term.
This view is reinforced by drug manufacturers, who say that the results "underscore the persistent nature of obesity," similar to managing conditions like high blood pressure.
User Experiences
Individuals who have come off the medication explain a sudden resurgence of hunger.
"I experienced a switch flipping and you're instantly ravenous," said an individual.
The struggle is compounded if patients have not developed sustainable lifestyle or habit changes during therapy.
Growing Interest
Recent estimates show that millions of people in the UK have used weight-loss jabs in the past year, with desire continuing to grow.
- Adoption is greater among women compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
In conclusion, clinicians emphasize that while these medications are powerful agents for shedding pounds, they are not a magic solution and maintained weight loss hinges on integrated behavioural support.
