As females approach menopause, contrary to popular belief, weight gain is not inevitable. Eating and exercise patterns should return to normal after birth, and metabolism will return to its previous state (American Pregnancy Organization, 2019). This causes the body to require more nutrients. Metabolism during pregnancy increases, in order to maximize calorie consumption for both mother and baby. The metabolism slows by around 200 calories and continues to go lower as age increases (Castle & Jacobsen, 2013). Metabolism proceeds to decline every year after 30. However, many people do not notice until weight gain begins to onset, which usually occurs when individuals reach their 30’s. Between the ages of 25-30, metabolism starts this decline. Physical activity can also decline due to lower energy or other health conditions occurring, which can contribute to weight gain as well. This correlates to a lower amount of muscle mass and higher energy consumption that leads to weight gain. In both males and females, the basal metabolic rate declines with age. “What is the BMR Calculator?” by Andy Sartori is in the Public Domain This is equivalent to negating one hundred fifty calories from daily consumption every ten years (Castle & Jacobsen, 2013). Metabolism does slow after puberty, and after the age of twenty will slow approximately 2% every ten years (Castle & Jacobsen, 2013). They need more calories per day, which will continue after puberty ceases, as boys need more calories to maintain their muscle mass. While boys grow to reach their adult height, their weight will distribute and will mostly be in the form of muscle. Teenage boys, on the other hand, grow between twelve and fifteen years old, gaining about fourteen pounds before age fifteen (Castle & Jacobsen, 2013). Teenage girls gain more weight than boys and have an average weight gain of one pound per month from eleven to twelve and a half years of age (Castle & Jacobsen, 2013). When young females go through puberty, their metabolic rate increases, the woman grows in height, and accumulates more of their womanly adipose tissue in their reproductive regions due to an increase in estrogen during this time. They also impact the body at different life stages, especially in females, who go through puberty, pregnancy, and menopause, all of which affect metabolism.Īfter the onset of puberty, hormones change and become a distinct contender in adiposity. Sex chromosomes and sex hormones also play a large role in this idea since they both regulate energy, homeostasis, metabolic disorders, and psychiatric disorders. Gender is not an excuse for lack of weight loss however, does play a role in their physical make up which directly correlates with metabolism patterns. “How Men and Women Store Fat Differently” by Weight Loss Science is in the Public Domain This causes weight loss to be more difficult for females and easier for males since they continuously are burning fat mass after exercising. After exercising, females burn more carbohydrates, while males begin burning fat after exercising. Females, however, have more slow-twitch muscle fibers, which means they use more fat while exercising. Therefore, the fat distribution in females is more beneficial. Having a higher amount of abdominal fat puts males at a higher risk of heart disease, diabetes, and other predisposed health conditions. females have two thirds the skeletal mass and twice the adipose tissue as males (Lundsgaard & Kiens, 2014). Males have more fat stored in their abdomen, whereas females have more fat between their muscles and skin and stored in their lower body. When examining the differences in gender metabolism, fat storage plays a key role in explaining the variations. Ninety percent of the energy used for every individual is due to muscle mass, fat mass, and activity level (Jefferson Regional Medical Center, 2018). However, the basic processes of metabolism remain the same in both males and females. These variations contribute to differences in weight loss and caloric intake. There are many differences in the physiology, functions, and quality of metabolism based on gender. Males and females both have metabolisms that are similar in nature, yet the stereotypical bodies for males and females vary, which causes the differences in how effective their metabolisms function. This includes converting food to energy to fuel the human body. Metabolism is the term that describes both chemical and physical processes that use energy.
