3. Factors that Affect Basal Metabolic Rate: Factor Age Height Growth Body Composition Fever Stresses (including diseases and certain drugs) Environmental Temperature Fasting/Starvation Malnutrition Thyroxine Effect on BMR In youth, the BMR is higher In tall, thin people, the BMR is higher In children and pregnant women, the BMR is higher the more lean tissue (muscle), the higher the BMR. The more fat tissue, the lower the BMR Fever raises BMR Stresses raise BMR Both heat and cold raise the BMR Fasting/starvation lowers the BMR Malnutrition lowers the BMR The thyroid hormone thyroxine is a key BMR regulator; the more thyroxine produced the higher the BMR
