IQ classification is the practice by IQ test publishers of labeling IQ score ranges with (somewhat subjective) category names such as superior or average. There are several publishers of tests of cognitive abilities.ike all current IQ tests, the Wechsler tests report a deviation IQ as the standard score for the full-scale IQ, with the norming sample median raw score defined as IQ 100 and a score one standard deviation higher defined as IQ 115 (and one deviation lower defined as IQ 85).
When fat mass decreases, the level of plasma leptin falls so that appetite is stimulated until the fat mass is recovered. There is also a decrease in body temperature and energy expenditure is suppressed. By contrast, when fat mass increases, so do leptin levels and appetite is suppressed until weight loss occurs.
Studies in mice have shown that giving animals leptin reduces overeating and obesity. However, many obese humans have been shown to have high amounts of leptin circulating in the blood, but it doesn't seem to affect appetite or energy expenditure. This is termed leptin resistance, because even though the body has more than enough leptin in it, it doesn't respond to it the way it's supposed to.
