After 50 gm of glucose of feed orally
Causes for Ketosis - Starvation: In starvation, the dietary supply of glucose is decreased. Available oxaloacetate is channelled to gluconeogenesis. The increased rate of lipolysis is to provide alternate source of fuel. The excess acetyl CoA is conveed to ketone bodies. The high glucagon level ors ketogenesis. The brain derives 60-75% of energy from ketone bodies under conditions of prolonged starvation. Hyperemesis (vomiting) in early pregnancy may also lead to starvationlike condition and may lead to ketosis. Ref: DM VASUDEVAN TEXTBOOK OF BIOCHEMISTRY, EIGHTH EDITION, PG.NO.,206.
