Macro partitioning
Increasing daily protein intake to 1.0–1.5 g/kg/day in older adults improves glycemic control and preserves muscle mass, counteracting age-related sarcopenia and insulin resistance.
If you are over 40 and concerned about diabetes or muscle loss, aim for 1.0 to 1.5 grams of protein per kilogram of body weight every day. This is higher than the standard recommendation and helps protect your muscles while improving how your body handles sugar. Focus on high-quality sources like dairy or whey, and combine this with resistance exercise for the best results.
Protein consumption upwards of 1.0–1.5 g/kg/day in older adults is able to induce improvements in glycemic control and muscle mass.
