WHAT IS BMR? WHAT ARE THE FACTORS AFFECTING BMR
- BMR is basal metabolic rate.
- Basal Metabolic Rate is the minimal caloric requirement needed to sustain life in a resting individual.
- This is the amount of energy your body would burn if you slept all day (24 hours).
FACTORS AFFECTING BMR :
- AGE: In youth, the BMR is higher; age brings less lean body mass and slows the BMR.
- HEIGHT: Tall, thin people have higher BMR.
- GROWTH: Children and pregnant women have higher BMR.
- BODY COMPOSITION: More the lean mass tissue, higher is the BMR, more fat tissue, lower is the BMR.
- FEVER: Fevers can raise BMR
- STRESS: Stress hormones can raise the BMR
- ENVIRONMENTAL TEMPRETURE: Both the heat and cold raise the BMR
- FASTING / STARVATION: Fasting and starvation lowers the BMR
- MALNUTRITION: Malnutrition lowers the BMR
- THYROXIN: The thyroid hormones thyroxin is the key BMR regulator , more thyroxin produced , the higher the BMR
