A recent study suggests that individuals who stop using blockbuster weight-loss injections like Mounjaro or Wegovy may regain lost weight at a significantly accelerated pace than those who halt traditional lifestyle programs.
Findings released in a prominent health publication points out that while overweight individuals can lose about a fifth of their body weight while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"People purchasing such drugs must be cognizant of the danger of rapid rebound weight gain when the medication concludes," cautioned researcher Dr. Susan Jebb.
Such speed of recovery means a reversion to starting mass in about a year and a half.
Comparing Therapies
The research, which examined 37 of studies involving thousands of patients, contrasted the outcomes of these new drugs with conventional dieting.
The team point out that individuals who shed pounds through diet and exercise usually have a more gradual weight regain—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Nutrition scientists propose the way of the drugs accounts for the heightened regain.
These medications copy a natural hormone called glucagon-like peptide-1, which controls appetite.
"Sustained high doses of the hormone levels far above than normal could lead to the body to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its effects," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication results in appetite is no longer kept in check, making binge eating far more likely."
An Ongoing Condition?
Medical guidelines recommend the jabs for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Many experts argue that, considering the likelihood of relapse, the therapy is often long-term.
This opinion is echoed by drug manufacturers, who say that the findings "underscore the chronic character of obesity," comparing it to managing diseases like hypertension.
Patient Accounts
Users who have stopped the medication report a sudden resurgence of cravings.
"It was like a switch activating and you're instantly extremely hungry," described one woman.
This difficulty is compounded if patients have not established permanent lifestyle or habit modifications during treatment.
Growing Use
Figures show that millions of people in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is higher among women compared to men.
- 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, experts stress that while the jabs are powerful tools for weight loss, they are not a permanent fix and long-term success hinges on ongoing lifestyle management.
