Activist Anna Hazare had lost five kg of weight as he entered his seventh day of fast for a strong anti-corruption bill on Monday, Team Anna member Arvind Kejriwal said.
"Ketone particles have been traced from his blood and urine... He has lost five kg of weight, his health is all right otherwise," Kejriwal told reporters at Ramlila Ground where Anna Hazare is sitting on fast.
Ketones are particles created by the body during starvation, and are meant to provide an alternate source of fuel from fatty acids.
Anna Hazare was detained Aug 16 and taken to Tihar Jail, where he remained until Friday when he shifted to Ramlila ground.
