Patients Stopping Slimming Medications Put On Pounds Far More Rapidly Compared to Those on Conventional Diets

New research reveals that people who discontinue new slimming jabs like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who halt traditional lifestyle programs.

Published data in a prominent medical journal shows that while obese people often shed a large proportion of their body weight while on the medication, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.

"People purchasing such drugs should be cognizant of the risk of rapid weight regain when the treatment concludes," stated expert Dr. Susan Jebb.

That rate of regain implies a reversion to pre-treatment weight within about a year and a half.

Weighing Treatments

The analysis, which examined 37 of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with older methods.

The team emphasize that people who lose weight through diet and exercise usually see a more gradual creep back—around 0.1 kg a month—after stopping.

The Reason for the Quick Rebound

Nutrition scientists believe the mechanism of the injections explains the accelerated rebound.

The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.

"Artificially providing GLP-1 levels far above than the body's typical production might result in the system to produce less of its own natural hormone, and could diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics specialist.

"Discontinuation of this hormone supplement leads to appetite is unsuppressed, making excessive eating much more probable."

An Ongoing Condition?

Medical guidelines advise the injections for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.

A number of clinicians say that, given the high risk of relapse, the therapy might need to be ongoing.

This view is reinforced by drug manufacturers, who say that the findings "highlight the chronic nature of excess weight," akin to managing diseases like hypertension.

User Accounts

People who have stopped the medication describe a sudden resurgence of cravings.

"I experienced a switch activating and you become ravenous," recalled one woman.

This challenge is worsened if individuals have not established permanent dietary or behavioural modifications during treatment.

Significant Interest

Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the past year, with desire being substantial.

• Adoption is more common among women than men.
• The 40s and 50s age group shows the greatest level of interest.
• A large proportion access the drugs through private prescriptions rather than the NHS.

In conclusion, clinicians stress that while GLP-1 drugs are powerful agents for weight loss, they are not a permanent fix and lasting health benefits relies on combined behavioural changes.
