A new class of weight loss medications is generating excitement with remarkable results, and for many, it delivers. However, if you reach your desired weight after months of weekly injections and choose to discontinue the medication, here’s what you should know: the chances of regaining the lost weight are high.
Research indicates that obese individuals can shed 15% to 20% of their body weight within approximately a year. When treatment is halted, studies suggest you might regain about two-thirds of the weight you shed over the next 12 months.
These medications, commonly referred to as GLP-1 agonists, are available under various brand names like Ozempic, Wegovy, and Mounjaro. They imitate naturally occurring hormones that induce feelings of fullness, thereby suppressing appetite and promoting weight loss. However, these effects persist only while you’re actively taking the drug.
This applies whether the medication is used for cosmetic weight loss or as preventive care against conditions linked to weight, such as type 2 diabetes, heart disease, and certain cancers.
The solution might seem straightforward: continue taking the medication. Yet, not everyone can sustain weekly injections for life due to factors like high costs and potential side effects.
“Being in treatment permanently typically isn’t what people seek, especially if they’re funding it themselves,” states Professor Susan Jebb, a nutritionist at the University of Oxford. “People aspire to lose weight and sustain it.”
About half of the people who initiate weight loss medication will discontinue it within a year. If you fall into this category, there’s a significant chance you’ll regain lost weight, but there’s also a range of strategies to help maintain your progress.
Understanding Weight Gain Challenges
After any type of weight loss, whether achieved naturally or through medication, the risk of regaining that weight exists. This dilemma has been a longstanding challenge for nutritionists.
“Maintaining weight loss is a significant hurdle in effective weight management. We have numerous methods to assist individuals in losing weight, yet the focus on sustaining weight loss is lacking,” emphasizes Jebb.
After substantial weight loss, the body’s inclination is to reclaim the original weight. Consuming even modest meals can result in weight gain due to heightened hunger levels coupled with a slowdown in metabolism.
Weight loss medications complicate this issue. While they simulate satiety hormones such as GLP-1, they can diminish the body’s natural fullness signals. Consequently, ceasing the medication may intensify hunger, making maintenance tricky.
As a result, weight regain can occur swiftly. Research by Jebb’s team at the University of Oxford found that patients typically regain their previous weight within two years of discontinuing the treatment. However, individual responses vary widely.
“There is considerable variability,” Jebb remarks. “Determining why some individuals succeed while others don’t remains unclear.” Until further insights arise, Jebb and other nutritionists advise reverting to established recommendations of diets and exercise. While this may not be ideal, particularly following struggles with conventional methods, it remains the best course of action available.

Preparations for Discontinuation
According to Professor Giles Yeo of the University of Cambridge, preparing for success prior to ending weight loss medications is vital.
“Utilize your time on medication to cultivate new habits,” suggests Yeo. “With appetite suppression, you’ll find it more manageable to adopt healthier eating behaviors.”
When hunger is suppressed, it’s easier to modify eating patterns such as emotional or mindless snacking, he explains.
Establishing sustainable habits during medication use can provide a significant advantage in maintaining weight loss long-term, according to Yeo.
Yeo also advocates for incorporating exercise into your routine while on weight loss medications. Studies reveal that physical activity aids weight maintenance, with a Danish study from 2024 showing participants in a post-medication exercise regimen were more likely to retain at least 10% of their weight loss.
“This emphasizes how beneficial exercise can be,” Jebb points out. “This finding particularly applies to individuals committed to structured and supervised exercise routines.”
Effective Appetite Management Strategies
While establishing healthy habits is crucial, managing appetite without medication poses additional challenges, particularly when cravings strike. However, smart dietary choices can mitigate these urges.
Focus on nutrient-rich foods such as protein and fiber instead of carbohydrates.
“Both protein and fiber travel further along the digestive tract and naturally stimulate GLP-1 release, enhancing feelings of fullness,” explains Yeo. “Your aim is to maintain elevated GLP-1 levels through your diet. While it won’t reach levels achieved through medication, striving for this is essential.”
Research suggests that certain foods, like eggs, can enhance satiety. One study found that consuming eggs for breakfast could lead to prolonged fullness compared to higher-carb options like cereal or toast, consequently decreasing lunch intake.
Other protein-rich foods such as red meat, fish, tofu, and Greek yogurt may yield similar benefits.
Additionally, incorporating certain ingredients like fat or fiber can slightly increase GLP-1 levels. Foods like berry, olive oil, nuts, avocados, oats, lentils, beans, green onions, onions, and asparagus are recommended.
Lastly, practicing mindful eating by consuming meals slowly can significantly improve feelings of fullness, even if the portion sizes remain consistent.
“Eating slowly, increasing fiber intake, incorporating more protein, and reducing sugar are all beneficial strategies,” Jebb states. “There isn’t a one-size-fits-all solution; these are all incremental improvements we know work.”
Looking Ahead for Weight Management Solutions
While developing healthier eating habits and increasing physical activity can be beneficial, these measures may not be sufficient to prevent weight regain for everyone.
“Reducing food intake requires conscious effort, and many struggle to implement this independently,” comments Jebb. “If you’re using these medications, genetic predispositions to overweight may play a role.”
Yeo notes these strategies may only benefit a subset of the population, primarily those whose weight issues are more attributed to lifestyle than genetics.
“Obesity exists on a spectrum,” he explains. “The severity of one’s obesity and its underlying causes will largely influence the effectiveness of any approach.”
For individuals needing medical assistance to sustain weight loss, help is on the horizon. Pharmaceutical companies are innovating low-dose weight loss medications, available in both pill and injection forms, intended to aid gradual weaning off while minimizing weight regain.
Nevertheless, research indicates that even temporary weight loss can yield long-lasting health benefits.
“Taking the time to reach a healthy weight will produce positive long-term outcomes,” asserts Yeo. “And the longer you maintain a healthy weight, the better your future prospects. Thus, even if you regain some weight, the benefits of the drugs remain considerable.”
