Bmr stands for your basal metabolic rate. This is the amount of energy or calories required to sustain basic body functions such as digestion, breathing, and circulation. It is calculated using the revised Harris-benedict formula. The formula is:

Male: (88.4 + 13.4 x weight) + (4.8 x height) – (5.68 x age)

Female: (447.6 + 9.25 x weight) + (3.10 x height) – (4.33 x age)

Variables that affect your bmr is height, weight, age, and physical activity. Menopause can also affect your bmr. When the variables are plugged in, the result is the calories you need to consume to maintain your weight. If you add calories, it will put you in a caloric surplus. This means you will gain body fat as well as muscle if you are weight training. If you subtract calories from you bmr, you will be in a caloric deficit. This means will loss body fat, as well as some muscle depending on how many calories are subtracted and if you are remaining active.

Most Vitamins and minerals are excreted when excess amounts are consumed. However, when very large excessive amounts are consumed, such as vitamin A, the results may he liver toxicity and birth defects. Extreme excess in vitamin c can cause kidney stones as well. Water soluble vitamins (C, B) are secreted in urine. Fat soluble vitamins (A, D, E, K) are stored in liver and fat tissues. Fat soluble vitamins are more likely to be toxic because of slower absorption and longer storage.
