A composition for promoting energy metabolism, a composition for promoting sympathetic nerve activity, a composition for promoting fat burning, an antiobestic composition or a composition for elevating body temperature, each composition comprising 1-(3',4',5'-trihydroxyphenyl)-3-(2",4",6"-trihydroxyphenyl)-propan-2-ol. The compositions according to the present invention have excellent effects of promoting energy metabolism, promoting sympathetic nerve activity, promoting fat burning, controlling obesity (i.e., suppressing body weight gain or reducing body weight) and elevating body temperature. Therefore, these compositions are possibly efficacious for elevating body temperature, ameliorating hypothermia, controlling obesity, reducing visceral fat, achieving cosmetic effects, promoting metabolism, stimulating immunity, relieving fatigue, ameliorating depression, etc.1-(3’,4’,5’-trihydroxyphenyl)-3-(2’’,4’’,6’’-trihydroxyphenyl)-propan-2-olを含有するエネルギー代謝亢進用組成物、交感神経活動亢進用組成物、脂肪燃焼促進用組成物、抗肥満用組成物、又は体温上昇用組成物。本発明の組成物は、優れたエネルギー代謝の亢進作用、交感神経活動の亢進作用、脂肪の燃焼促進作用、抗肥満（体重増加の抑制又は体重の減少）作用、体温の上昇作用を有するものであり、例えば、体温上昇、冷え性改善、抗肥満、内臓脂肪低減、美容、新陳代謝促進、免疫賦活、抗疲労、抗鬱等の効果が期待できる。
