The poignant image shows the man looking down at a shopping list in front of bare shelves in his local store in Epsom, Surrey.
Other shocking images of pensioners looking for food in supermarkets with limited supplies have also circulated on social media.
Lauren Taylor, 34, who took the photo of the gentleman, said she hoped the picture would kick the public into action to take care of the elderly.
The mum-of-two explained that multiple aisles on the supermarket had limited supply.
She said: “It was awful and just really sad. That was only one aisle and the others were in a similar state of empty shelves.
“People were grabbing lots of the stuff that were still on the shelves.
“It’s really just sad and disappointing in society that it’s got to this point.
“Everyone needs stuff, but he had been left with nothing.”
Supermarket giants have moved to limit the number of crucial items people can buy.
Tesco said shoppers will be limited to buying just three products per line from Thursday.
Chief executive Dave Lewis added all counter services will close, to free up staff to restock shelves, and a priority hour will be launched at larger stores between 9am and 10am every Monday, Wednesday and Friday.
Stores that previously opened 24 hours, will also now close at 10pm each evening.
