New research indicates that people who come off new slimming jabs like semaglutide or tirzepatide may regain reduced body mass far faster than those who halt traditional lifestyle plans.
Published data in a major medical journal shows that while overweight individuals can lose substantial amounts of their body weight while on the medication, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"People buying such drugs need to be aware of the danger of quick rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a reversion to starting weight in about a year and a half.
Analyzing Therapies
The research, which examined 37 of studies involving thousands of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Scientists note that people who lose weight through dieting generally see a less rapid creep back—perhaps 0.1 kg a month—post-intervention.
The Reason for the Quick Rebound
Nutrition scientists propose the mode of action of the injections accounts for the amplified regain.
These medications imitate a body's own chemical called GLP-1, which helps regulate appetite.
"Artificially providing GLP-1 levels several times higher than normal might result in the body to generate a reduced amount of its own natural hormone, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement leads to appetite is unsuppressed, making overeating a significant risk."
A Chronic Condition?
The NHS recommend the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts argue that, considering the significant potential of weight regain, the treatment should be considered ongoing.
This opinion is reinforced by drug manufacturers, who say that the findings "underscore the persistent character of excess weight," akin to managing diseases like hypertension.
User Accounts
Individuals who have discontinued the jabs describe a sudden resurgence of cravings.
"It was like a switch activating and I was suddenly starving," described one woman.
The struggle is worsened if patients have not adopted sustainable dietary or behavioural modifications during treatment.
Significant Interest
Survey data indicate that millions of people in the UK have used these injections in the past year, with demand remaining high.
- Use is higher among women than males.
- The 40s and 50s age group shows the highest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, experts stress that while the jabs are potent tools for weight loss, they are not a permanent cure and long-term success likely depends on integrated behavioural changes.
