Glp 1s FAQs

While exercise cannot completely prevent weight regain after stopping GLP-1s (the metabolic shift is significant), a strong exercise foundation, particularly built-up muscle mass and improved insulin sensitivity, significantly reduces rebound weight gain. Maintaining consistent resistance training and aerobic exercise, combined with sustainable nutrition habits established during the medication phase, minimises the crash. The best approach is building a robust exercise program while on GLP-1s so that fitness gains and metabolic adaptations persist when medication stops.

Start with lower intensity and gradually progress while taking GLP-1s. Dizziness may indicate dehydration or blood pressure drops. Ensure adequate hydration and allow recovery between sets. Fatigue suggests excessive volume; reduce frequency or duration initially, then progress slowly. Time exercise timing: avoid immediately after GLP-1 injections (48 hours is ideal). Ensure adequate carbohydrate intake pre/post-exercise, monitor blood glucose, and communicate regularly with both your CEP and prescribing clinician about symptom timing and patterns

LP-1 medications accelerate weight loss, including muscle mass. To prevent sarcopenia: prioritize resistance training 2-3 times weekly focusing on compound movements (squats, rows, presses), ensure adequate protein intake (1.2-1.6g/kg body weight), perform strength work early in your exercise week when energy is highest, use progressive overload to maintain muscle stimulus, and work with your Clinical Exercise Physiologist to coordinate training intensity with medication timing. Regular strength assessments help track muscle retention

While GLP-1 medications are powerful tools for reducing appetite, the quality of your weight loss depends on your physical activity. Combining these medications with a Clinical Exercise Physiology (CEP) programme shifts the focus from 'weight loss' to 'body recomposition.' The impact of this combination includes: Improved Fat-to-Muscle Ratio: Research shows that without resistance training, up to 25–40% of weight lost on GLP-1s can come from lean muscle tissue. A CEP ensures that the weight lost is predominantly body fat. Maintenance of Resting Metabolic Rate (RMR): Muscle is a metabolically active tissue. By preserving muscle through clinical loading, a CEP helps keep your metabolism high, making it significantly easier to maintain your new weight long-term. Cardiovascular Protection: GLP-1s can sometimes cause a slight increase in resting heart rate. A CEP monitors your cardiac response to ensure your heart health improves as your weight drops. Functional Vitality: Rather than just becoming a 'smaller version' of yourself, clinical exercise ensures you have the strength, bone density, and energy to enjoy your new weight. The medication handles the scale; the Clinical Exercise Physiologist handles your, strength, muscle mass and the long term sustainability.

Yes. In fact, Clinical Exercise Physiologists (CEPs) are the primary allied health professionals recommended for patients using GLP-1 receptor agonists. While these medications are highly effective for weight loss, they carry a significant risk of muscle mass loss (Sarcopenia) and metabolic slowing. A CEP specialises in the exercise prescription required to protect your health while on these drugs: Preserving Lean Muscle: Using targeted resistance training to ensure the weight you lose comes from fat stores, not vital muscle tissue. Managing Side Effects: Designing safe workouts that account for common GLP-1 side effects such as fatigue, nausea, and changes in heart rate or blood pressure. Metabolic Protection: Building the 'metabolic engine' (muscle) needed to prevent weight regain once the medication cycle ends. Nutritional Education: Working alongside your prescriber and nutritionist, if you have one, to ensure your activity levels match your reduced caloric intake. Taking a GLP-1 without a supervised clinical exercise plan can lead to a reduction in muscle mass, as the medication is indiscrimate what tissue you lose, potentially resulting in a slower metabolism. A CEP ensures your weight loss is healthy, functional, and permanent.
