What can affect metabolic rate?

Answer 1

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.

Answer 2

Your genetics, diet, gender, weight, amount of exercise, outside temperature, age all affect your metabolic rate.
Drugs and hormones (i.e. what mood you're in) also affect it and the amount of energy you use.
Lastly, your muscle mass to fat ratio affects your metabolism.

Answer 3

there are many factors affecting a persons metabolic rate including

fat:muscle

size

activities

DNA

age

gender

diet

health/illness

drugs

external temperature

Answer 4

High blood pressure, and chemical's reaction make you not hungry therefore your body acts in different ways to get rid off your metabolic rate.

Answer 5

Hormones and the amount of E. Coli in the intestines, which help regulate the digestion process, are some of the things responsible for the metabolic rate.
