Different effects of puberty on resting metabolism in white and African American children
...bility that lower REEs among African-Americans may persist into adulthood is suggested by previous studies of African American adults that show that they too have a lower REE than whites. Whether this lower REE contributes to the development of obesity in African Americans cannot be proven at this time. The ...New study reveals a major cause of global warming - ordinary soot
