Individuals Stopping Weight-Loss Medications Put On Pounds Four Times Faster Compared to Those on Conventional Diets

A recent study suggests that people who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who stop traditional diet and exercise programs.

Research printed in a leading health publication shows that while overweight people can lose substantial amounts of their total mass while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month after stopping.

"Individuals using such drugs must be aware of the risk of rapid weight regain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.

That rate of regain means a return to pre-treatment weight within about 18 months.

Comparing Treatments

The analysis, which looked at 37 of trials involving over 9,000 of patients, compared the effects of these new drugs with conventional dieting.

The team note that people who shed pounds through dieting usually experience a less rapid creep back—around 100 grams monthly—once they finish.

Understanding the Quick Rebound

Experts believe the mode of action of the injections explains the amplified weight return.

The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.

"Sustained high doses of the hormone concentrations several times higher than normal might result in the system to generate a reduced amount of its own natural hormone, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.

"Discontinuation of this GLP-1 'fix' leads to appetite is no longer kept in check, making excessive eating far more likely."

A Chronic Condition?

Medical guidelines suggest the jabs for individuals with weight-linked health risks, alongside prescribed lifestyle changes.

Many experts contend that, considering the significant potential of relapse, the therapy might need to be ongoing.

This opinion is echoed by drug manufacturers, who state that the results "emphasize the persistent nature of excess weight," akin to managing conditions like hypertension.

Patient Accounts

Individuals who have stopped the medication explain a sudden return of appetite.

"It felt as if a trigger that goes on and you become extremely hungry," described one woman.

This difficulty is worsened if users have not developed permanent dietary or behavioural changes during treatment.

Widespread Interest

Recent estimates indicate that millions of adults in the UK have used these injections in the past year, with interest being substantial.

• Adoption is higher among females than men.
• The middle-aged demographic shows the greatest usage rates.
• A large proportion access the drugs through private healthcare rather than the NHS.

Ultimately, experts emphasize that while the jabs are potent tools for weight loss, they are not a permanent solution and long-term success hinges on ongoing lifestyle management.
