Since sources close to the singer indicated that she substitutes meals with infant puree while on tour, supermarkets have reported a surge in such products.
According to grocery website Ocado, sales of Heinz Mum's Own Creamed Porridge have risen by 100%, while pasta and spaghetti bolognese purees have increased by 87%.
"Sales of baby food have been static but since Lady GaGa was reported to be a fan, demand has gone through the roof as women are copying her eating habits," a spokesperson told The Mirror.
The 'goo diet' was devised by celebrity personal trainer Tracy Anderson, who has previously worked with Madonna and Gwyneth Paltrow. The programme includes one main meal per day with snacks of 4oz jars of the baby food to ward off hunger.
Health experts have warned that the diet could be dangerous.
