Some experts have proposed that eating extra protein will promote muscle growth in older adults. It turns out that this is not true.
A careful study of 92 men age 65 and older revealed that eating extra protein without increasing physical activity, especially weight bearing activity, did not result in promoting muscle growth.
This is not news to us. We have been lecturing and teaching in our courses and books that in order to maintain your muscle mass and certainly to increase it you must eat a healthy diet and exercise properly. All of this and more is in our book Live Longer Live Healthier.
