BMI: Your Body Mass Index (BMI) is a number with which everyone should become familiar. It’s really easy to move from being normal, to overweight or obese – level I, II, & III. http://en.wikipedia.org/wiki/Body_mass_index
BMR: Arguably, Basal Metabolic Rate is more important. Checkout the number of calories required to sustain life if the day was spent at rest in bed. Run the numbers for the weight you are today and your goal weight and start to finally figure out how many ‘extra’ calories you have been consuming. http://en.wikipedia.org/wiki/Basal_metabolic_rate
| Little to no exercise | Daily calories needed = BMR x 1.2 |
| Light exercise (1–3 days per week) | Daily calories needed = BMR x 1.375 |
| Moderate exercise (3–5 days per week) | Daily calories needed = BMR x 1.55 |
| Heavy exercise (6–7 days per week) | Daily calories needed = BMR x 1.725 |
| Very heavy exercise (twice per day, extra heavy workouts) | Daily calories needed = BMR x 1.9 |
HOT TIP: In order to lose weight, use 80% of current weight BMR calories – not the sedentary but the BMR. That will jumpstart the weight loss.
