How The Female Body Metabolism Changes From 20, 30, 40
The female body has been the subject of much discussion, and scientific research. In the recent years, the internet has added more to the discussion. When it comes to weight gain, dip in energy and general lack of enthusiasm and drive, the metabolism is to be blamed. It is generally known that the metabolism slows down as the body ages. It is important to know how your metabolism changes over your 20s, 30s and 40s if you want to keep your body in the pink of health.
In the 20s
Most women, on an average, have the highest RMR or Resting Metabolic Rate in their 20s. This means their body begins to burn calories even during rest. The RMR is partly dependant on genetics although much of it can depend on the level of physical activity of a woman. There are fewer commitments in the 20s, and there is more time to move about freely. Until 25, the body builds bone constantly and this gives a boost to the calorie combustion process. During the late 20s, the body cannot cope with flippant diets as much as during the early 20s. However, regular workouts and a cleaner diet can help the body to recover fast.
In the 30s
During the 30s, the muscle mass begins to take a dip and there is a loss of 1% every year. The RMR has a direct association to the muscle mass. The greater the muscle mass, the higher the energy that the body burns even at resting stage. The loss of muscle mass can be compensated and prevented with strength training for around 2-3 times per week. Strength training sends message to the body that is needs muscles. If the body feels that it does not need them, it begins to store more amount of fat. The female body, due to the lack of as much testosterone as the male body, needs greater effort to maintain the muscle mass. The 30s is also the time when the body produces less HGH (Human Growth Hormone), and the metabolism takes a dip as a consequence. Strength training also helps give a boost the HGH levels. Naturally, women need to hit more weights.
In the 40s
The level of HGH, progesterone and estrogen begins to decline heavily during the 40s, and the reproductive capacity falls rapidly. The metabolism begins to slow down rapidly, and the body does not burn as much energy as it used to. Caroline Apovian, MD, author of “The Overnight Diet: The Proven Plan for Fast and Permanent Weight Loss” holds that shrinking muscle mass is the main reason for sluggish metabolism. This makes reducing caloric intake essential for weight management. However, a woman with a sedentary lifestyle in the 20s and 30s can have a higher metabolic rate in her 40s, if she follows a proper workout and diet regimen. Strength training is essential for reversing or preventing sarcopenia, or dip in muscle mass, and coping with the loss of lean mass. Other than hitting the weights, women also need to consume around 100 – 120 grams of protein every day to boost their efforts to increase or maintain metabolic rate and aid their weight loss efforts. Douglas Paddon-Jones, PhD, says that protein-rich foods are broken down into amino acids and these are used by the body to build muscle mass and maintain them.
