What Is The Difference Between BMR and BMI?

Body mass index or BMI, is a numerical way of measuring a person’s body weight that is circumvented around the person’s weight and height.BMI is utilized to determine what weight range a person’s fat consistency is. In retrospect, BMR  is a reference to an individual’s Basal Metabolic Rate, or the  amount of calories burned by a person within a day, whether being active or lying still.

An individuals ideal BMI,typically,remains constant. This is as long as their height is consistent, and  ideal weight will always stay in a specific BMI range.  However, a BMI will fluctuate as weight and muscle are gained. Indifferently, an individual’s BMR,  will decline as age progresses. This is because as an individual ages metabolisms slow up naturally.

There are other factors that can cause metabolism to slow up. This may include even  not eating enough or starving and fasting. What happens is your body expects a certain amount of calories to sustain itself, and when this stops- it holds on to fat stores. In most instances when you eat less, you may find your body’s metabolism slowing down to compensate for this shock So, if you start eating less, your body will lower its metabolism rate further in order to keep more of the calories.

One of the most sure fire ways to increase your basal metabolic rate is to start a healthy diet, and a regular exercise routine. It is a given that body’s that burn more energy with exercise, have increased and boosted metabolisms. That is why hard core athletes must eat an extended amount of calories in order to sustain the amount of calories that they are burning each activity.

What BMI and BMR Calculations Mean:

Both your BMR and BMI  are calculated by weight and height, however, your BMR is determined also by adding sex, and age into the equation. A BMI helps assess your health requirements, and a BMR assists in determining what changes need to made to your weight loss routine in order to be where you want.

Used in unison these measurements can assist you greatly in achieving your ideal weight and optimal health range. Just be sure to understand and know what each means and the difference between the two! Try Our: BMI Calculator Today!

    A recent meta-analysis in the CMAJ (Harris KC, Kuramoto LK, Schulzer M, Retallack JE. Effect of school-based physical activity interventions on body mass index in children: a meta-analysis. CMAJ. 2009 Mar 31; 180(7):719-26 found that school-based physical activity interventions did not improve BMI. Although there were significant health benefits including reduced blood pressure, increased lean muscle mass, increasing bone mineral density, increasing aerobic capacity, and improving flexibility, the authors concluded that current population-based policies that mandate increased physical activity in schools are unlikely to have a significant effect on the increasing prevalence of childhood obesity.

    From a public health perspective, physical activity should be included and promoted within schools because it is an important component of a healthy lifestyle and improves many aspects of health, but there is currently no evidence that it is an effective method to reverse the trend of increasing BMI in children.

    Obesity has been described as a “complex system” with an individual’s energy intake and energy output, and resulting weight, being influenced by a range of highly interconnected factors. These factors can operate at the individual level (ie. genetic predisposition to obesity, learned activity patterns) or at the broader environmental and societal level (ie. how suitable an area is for walking, portion sizes, societal pressure to consume, food marketing). No simple changes, such as school-based physical activity interventions, can be expected to influence the prevalence of obesity in children. Such an approach has been described as “the futility of isolated initiatives”. Instead, in order to combat the rising prevalence of childhood obesity, investment needs to be made in a range of “community-based cross-disciplinary long-term strategies” that work at multiple levels. Examples may include provision of healthy school meals, improved urban planning (ie. by-laws restricting the proximity of fast food outlets to schools and provision of bicycle lanes), and control of the advertising of junk food to kids.

    I don't think you understood Tyra's stance on weight. Her view on weight is, as long as you're healthy and don't endanger yourself to be a certain weight, be happy how you are. Many people also say Tyra is a hypocrite because she said she loves her body and lost around 25lbs. This isn't true either because her weight was affecting her IBS, so she did it for health purposes.
