Older adults using GLP-1s should pay particular attention to three things, according to the CEO of the American Council on Exercise

Key Points:

• Weight loss principles such as maintaining a slight calorie surplus, regular exercise, especially resistance training, and increased daily activity remain consistent across adulthood, including for users of GLP-1 obesity medications.
• Older adults using these medications should focus on preserving strength, lean muscle mass, and physical function to counteract age-related muscle loss, bone weakening, and reduced mobility, with resistance training and adequate protein intake being critical.
• Resistance training is recommended at least two days per week for most adults on obesity medications, emphasizing gradual progress, joint comfort, and consistency rather than bodybuilding.
• Protein intake should be tailored to support muscle maintenance and recovery, with older adults advised to consume approximately 1.2 to 1.6 grams of protein per kilogram of bodyweight daily, adjusted based on individual health conditions and needs.
• Safety and individualized programming become increasingly important for adults in their 70s and beyond to preserve independence, balance, and mobility while using obesity medications.
