GLP-1 medicines are helping many people achieve significant weight loss, offering new treatment options for obesity and related health conditions. However, medical experts say long-term success should be measured by improvements in overall health rather than the reading on the scales alone. Alongside medication, regular physical activity, strength training and personalised care remain essential parts of effective weight management. Taking a Broader View of Weight ManagementGLP-1 receptor agonists have been shown to reduce body weight and body mass index (BMI), making them an increasingly important treatment for people living with obesity. However, clinicians are encouraging a shift in focus from weight alone to broader measures of health. “PCPs [primary care physicians] should shift the focus away from the number on the scale and toward meaningful improvements in overall health,” said Catherine Varney, DO, obesity medicine director at UVA Health in Charlottesville. Varney said a comprehensive approach should include the “5 M’s” framework: meals, movement, mind, medications and metabolic surgery. According to her, this approach “supports more meaningful outcomes by prioritizing metabolic health, functional capacity, and quality of life rather than weight alone. ”For New Zealand patients, where obesity remains a significant public health challenge, specialists increasingly emphasise sustainable lifestyle changes alongside medical treatment to improve long-term wellbeing. Monitoring Progress During GLP-1 TreatmentDoctors prescribing GLP-1 receptor agonists should closely monitor how quickly patients lose weight while also watching for potential complications. Yuval Pinto, MD, assistant professor of medicine and part of the Healthful Eating, Activity, and Weight Program at Johns Hopkins School of Medicine in Baltimore, said clinicians should remain alert for nutritional deficiencies, loss of lean muscle mass that may increase the risk of sarcopenia, and reductions in bone density. He said a weight-loss rate of around 0. 5 to 1 pound (approximately 0. 2 to 0. 45 kilograms) per week is generally recommended and should be considered before increasing medication doses. Patients who regularly perform strength training may require higher protein intake to help preserve lean muscle. Exercise recommendations should also take into account age, previous injuries and each person’s physical capabilities. Pinto said primary care doctors should adopt a multidisciplinary approach to obesity management and consider referrals to obesity medicine specialists, registered dietitians and, where appropriate, personal trainers or physiotherapists. Creating Exercise Plans That Patients Can MaintainExperts say combining cardiovascular exercise with resistance training offers important benefits beyond weight loss, including maintaining muscle mass and supporting heart health. Pinto recommends several practical strategies:Start With Activities Patients EnjoyDiscuss the types of exercise patients genuinely enjoy to improve the likelihood they will continue being active over the long term. Explain Why Exercise MattersHelp patients understand how physical activity supports both their medical conditions and weight-management goals. Build a Structured PlanDevelop a gradual exercise programme with clear targets, such as brisk interval walking to improve cardiovascular fitness alongside strength training to preserve lean muscle. Adapt to Individual NeedsEncourage physical activity that matches each person’s functional abilities. For frail patients or those unable to perform conventional resistance exercises, alternatives such as sit-to-stand movements or resistance band workouts may be appropriate. Provide Ongoing SupportRegular follow-up appointments can help identify barriers when progress stalls. Clinicians may suggest home-based resistance equipment or under-desk walking devices when outdoor exercise or gym access is limited. Where necessary, referral to physiotherapy with clearly defined rehabilitation goals can provide additional support. Tailoring Advice to Individual CircumstancesVarney said understanding each patient’s circumstances is fundamental when recommending exercise. “Many face limitations due to medical conditions or physical disabilities, so an effective plan incorporates activities that are both safe and achievable for them,” she said. “I really reiterate to my patients is that physical activity plays a critical role in cardiovascular health, mental well-being, and long-term weight maintenance. ”She noted that effective home-based exercise options include body-weight workouts, resistance bands, fitness apps and online exercise videos. Walking on a treadmill, chair exercises, stair climbing, dancing, yoga, stretching and balance exercises using light weights can all help improve strength, stability and overall fitness while exercising at home. Monitoring Muscle Mass During Weight LossSignificant weight loss, particularly during GLP-1 receptor agonist therapy, may result in reductions in lean muscle mass. Pinto said primary care clinicians can monitor these changes using simple body composition measurements alongside clinical performance tests to assess strength and physical function. Tracking muscle health throughout treatment allows clinicians to identify concerns early and adjust care plans where necessary. Supporting Long-Term Muscle HealthAccording to Pinto, preserving and building lean muscle requires an evidence-based approach that includes adequate dietary protein, sufficient sleep for recovery and progressive strength training to stimulate muscle growth. He noted that daily protein requirements, sleep needs and exercise programmes should be tailored to each individual based on their physiological characteristics and overall health. Varney disclosed that she has served on an Eli Lilly advisory board and is a member of the Eli Lilly speakers bureau. ConclusionWhile GLP-1 medicines are changing the way obesity is treated, medical experts say medication alone is not enough to achieve lasting health benefits. Combining treatment with personalised nutrition, regular physical activity, strength training and ongoing clinical support can help patients protect muscle mass, improve cardiovascular health and achieve better long-term quality of life.
