As you get older your muscles tend to decrease in size, fat increases and your metabolism begins to slow down. When you have a fast metabolism, keeping off that extra weight and staying slim is an easy task, but as you begin to age and your metabolism decreases, weight loss becomes more difficult to achieve. As a senior, there are several lifestyle changes you can make to improve your metabolism, but check with your doctor before making them.
Perform an aerobic exercise such as walking, running, swimming or cycling. Exercise decreases your amount of body fat and increases your lean muscle mass, which enhances your metabolism.
