Metabolism calculator

Your metabolism, or BMR, is the smallest amount of caloric daily needs to maintain existence in a resting time of day. It can be found as quantity of energy (calculated in calories) expended by the person to stay in bed sleeping all day!  We can calculate the basal metabolic rate by metabolism calculator.

Our basal metabolic rate maintains us alive and supplies vital energy for existence support, which needs about 60% of the calories consumed on a daily basis. An extra 25% of calories are used during physical activity and one more 10% are used to process the foo we eat. Everybody can enlarge BMR.The metabolism can differ among people and is affected by a lot of variables counting universal physical condition, chronic health situation, lack of physical activity, and age.

Basal metabolic rate is the main part in determining overall daily calorie needs. BMR is strong-minded by a mixture of different aspects:

• Genetics. You can be borned with fast or slow metabolisms.
• Gender. Male have larger basal metabolic rate.
• Weight. Heavier people have higher basal metabolism.
• Age. BMR reduces with age. Every 10 years  it drops about 4 per cent.
• Exercise. Physical exercise (sports) is the majorinfluence on body weight by burning calories. It also provides a raise of your metabolism by building extra muscle.
• Diet. Starvation can vitally decrease basal metabolic rate by approximately 30 percent. Strict low-calorie diet programs may be the reason to go down with  your BMR for 20%.
• Body Surface Area. Tall people have larger BMR.
• Body Fat %. The lower your body fat %, the larger your BMR is.
• Body Temperature. If the body temperature increases, every  0.5C  of  an internal temperature shows the BMR to increase for 7%.
• External temperature.  Cold temperature will cause your basal metabolism to increase.
• Glands. Thyroxin is a main BMR-regulator. If we produce more thyroxin we have higher metabolism.
