Your metabolic rate is the rate at which chemical reactions like respiration take place. Factors which affect your metabolic rate are things like excersise, the proportion of muscle to fat in your body and inherited factors such as gender, age and weight. The more energy you need to use, the higher your metabolic rate. This means that things which need more energy such as excersise, will increase your metabolic rate. Over weight people usually have higher metabolic rates than slim people because their bodies are larger so they need more energy to work. The more muscle you have, the more muscle cells you have. Muscle cells require lots of energy to contract and move limbs. So the more muscles you have the higher your metabolic rate. Your gender is important because men have more muscle than fat in their bodies meaning they need more energy and will therfore have higher metabolic rates. People under the age of 20 have higher metabolic rates because their muscles are still growing and need more energy to do so.

Thyroxine and Triiodothyronine
Oxygen consumption is directly proportional to metabolic rate. As the body metabolizes nutrients to produce energy, it requires oxygen to carry out this process. Therefore, an increase in oxygen consumption indicates a higher metabolic rate, while a decrease in oxygen consumption indicates a lower metabolic rate.
Thyroid hormone, produced by the thyroid gland, plays a key role in regulating metabolic rate by controlling the body's energy production and consumption. Another hormone that affects metabolic rate is adrenaline, which is released by the adrenal glands in response to stress or danger, increasing energy expenditure and promoting the breakdown of stored nutrients for fuel.
The rate of Metabolism, or metabolic rate.
when you do exercise then you are felling that you mouscle are getting bigger and your body shape is diffrent and you are losing the calories.
The thyroid gland released thyroid hormone, which overall sets the basal metabolic rate. However, other hormones can temporarily affect metabolic rate, including epinephrine and norepinephrine.
the liver has a higher metabolic rate
Genetics is a significant factor influencing metabolic rate. Certain gene variations can impact the body's ability to process and burn energy efficiently. Additionally, age, sex, and body composition, which are also inherited to some extent, play a role in determining metabolic rate.
