Despite all the efforts, if you are not able to lose weight, it means that the function of your metabolism may be hindered. As we get older, aging slows down the metabolic function, which makes weight loss much difficult. Here is how the metabolism changes throughout the years.


The metabolism is crucial for losing weight, as it turns the food we consume into energy. If your metabolic rate is increased, the body is able to burn fat faster while resting than people whose metabolic rate is low. The resting metabolism indicates how much energy the human body needs in order to perform the main function. We can burn more calories, when we do regular exercises. However, if your metabolic rate is decreased, you cannot make it function faster even though you can enhance the metabolic process by including healthy food in your diet.


In the 20s

In the 20s, when you become an adolescent, the body continues to develop, particularly the body muscles and bones. This growth enhances the resting metabolism – the metabolism that function while we rest, like when we are sleeping. In fact, even though we rest and do nothing, the body is able to burn calories. However, according to the American Council on Exercises, the metabolic rate slowly decreases 1 – 2 % per decade.

In the 30s and 40s

Even though the metabolic rate is increased, the aging process can slow it down. Moreover, as we get older, the body muscles that support the bones get smaller, but the fat amount in the body increases. With age he percentage of fat in the body increases, whereas the skeletal musculature volume decreases. In the early 30s, the weakening and loss of muscles start. In addition, at this age, we are not producing the human growth hormone as before, which also leads to a decrease of the metabolic rate. After 45, people on average lose 10 % of their muscle mass, which is about 1/3 – ½ of muscle mass per year.

According to the researchers, this muscle mass change is mainly responsible for the metabolic rate. If the metabolic rate decreases, it means that the body needs less energy and less food. Nevertheless, if you eat more than the human body needs, the metabolism cannot turn all the food into energy and it stores it as fat in the abdomen.

In the 50s and 60s

Changes in the metabolic rate also occur as a result of the menopause period. According to the researches, when the women are in the menopause period, the body metabolizes the fat more difficulty, and stores it in fat after the menopause period.


According to the researches, the aging process can be slowed down by doing regular exercise and including healthy food in the diet.

Consume more whole foods

Include healthy whole foods, which are loaded with vitamins, minerals and nutrients essential for the body. Try to avoid or limit the intake of processed and refined food. In addition, even though fast food also makes you feel full, and sugary and salty foods can also satiate your appetite, you should consume whole foods that will stimulate burning of fat.

Be active

In the 40s, when there is a weakening and loss of muscle mass, the metabolism replaces the muscles with fat. For this reason, it is important to do regular exercise and stay active. A 6-month research has shown that women in postmenopausal period, who involves regular exercising in their weight loss, had increased metabolic rate than the women who did not exercises at all.

Planking exercises will help you to strengthen the upper muscles of the back, whereas backward running will help you strengthen your lower back muscles and gluts. Moreover, resistance, or weight training, boost up the metabolism and slow down the aging process. can In order to burn fat and strengthen your muscles, you can also do some simple exercises at home.
