No matter whether you start out as an apple or pear, your overall body shape will likely change as you age. This metamorphosis is due to a lot of factors that fall into two main categories: the ones that you can't control, and the ones that you can. The rate of these changes is connected to lifestyle factors like exercise, smoking, and the diet you consume. Here are the factors:The skeletal system that dictates the broadness of the pelvis, the width of shoulder bones, the distance between the pelvis and rib cage, and the shape of the rib cage deforms as you age. When a woman is pregnant, the rib cage widens because of the relaxing hormones. This is one of the reasons why post pregnancy, women lose their defined waist.
The distribution of fat tissues changes through time: The human body houses a considerable amount of fat. A study informed that, in men, the healthy body fat amount is 8-20 percent amongst 20-39 years old and 11-22 percent amongst 40-59 years old. In women, the healthy body fat is 21-33 percent amongst 20-39 years and 23-34 percent amongst 40-59 years. The body weight then becomes dependent on the number of calories the body consumes. When women eat more than their capacity to burn off, they gain weight. Without exercise, the extra weight is stored in the body in the form of fats instead of muscles. And with no exercise the increased proportion of fats in the body weight increases.
The belly fat eventually renders an apple-shaped body, which is often associated with diabetes, cardiovascular and a lot of other diseases. Since muscles burn less fats than calories, muscles somehow contribute to the overall health, weight, strength, and risk for disabilities. To minimize the percentage of muscle loss, it is best to remain physically active. It's not just the proportion of fat that changes over time its location changes, too. In women, the drop in estrogen levels that comes with menopause coincides with a shift of fat storage from the lower portion of the body towards the midsection. This belly fat is comprised of both subcutaneous fat under the abdomen and visceral adipose tissue i.e.fat that accumulates around organs deep within the abdomen.
Height loss: A lot of people isn't aware of the fact that not only can you get wider as you age, you also may get shorter. An adult can lose between one to three inches in height over their lifetime. This age-related body change is common in people of all races and sexes. Due to changes in bone mass, as well as in muscles and joints, a height loss of about 0.4 inches (1 cm) every 10 years is typical. After age 70, the loss accelerates.
Muscle: Skeletal muscle accounts for about 40 percent to 50 percent of total body weight in healthy adults. Loss of muscle tissue and strength (sarcopenia) results from decreased activity as you get older. Some researchers estimate that after age 30, adults experience a 1 percent loss of muscle mass each year. And to maintain muscle mass as you get older, you will have to remain physically active and be sure to include resistance exercise in your regimen.
