  • Micheal Jordan was 6’6” and 216 pounds and considered overweight
  • An athlete the same weight, but who is 5’10” and very muscular would have a BMI of 30, which is considered obese
  • Factors contributing to metabolic rate include age, height and weight, gender, muscle mass, stress, illness, altitude, temperature, hormones
  • In a new study published in the September issue of the American Journal of Clinical Nutrition (Am J ClinNutr September 1, 2012 vol. 96 no. 3 492-497), researchers found that the 3 most common lifestyle factors driving people to eat are alcohol consumption, television and sleep deprivation. Reward saliency is a wanting, a desire for (in this case food) that induces motivational behavior to obtain food. As the wanting increases (as in drug seeking behavior) the “liking” decreases.
  • Jeffrey Friedman, MD PhD is a lead researcher in the field of obesity and his research led to the discovery of leptin. Leptin is a hormone which increases the desire to be physically active and at the same time suppress appetite. Leptin is released by adipose tissue, the more fat, the more leptin and the greater the suppression of appetite. But, tissues can develop a resistance to leptin, just as tissues can develop a resistance to insulin.
  • Examples of NEAT activities are fidgeting, toe tapping and pacing. The term NEAT was coined by Dr. James Levine
