Narayana Reddy, an Indian cook whose YouTube channel, Grandpa Kitchen, garnered more than six million followers with videos of him preparing gargantuan amounts of food to feed orphaned children and other hungry people, died on Oct. 27 in India.

His death was confirmed in a video on his channel, but no other details were provided. Local news media reported that he was 73 and that he lived in the southern state of Telangana.

Mr. Reddy began the Grandpa Kitchen channel in 2017 by posting videos that followed a straightforward formula: adorable children, heartwarming music, inspirational sayings and seemingly absurd amounts of food.

The food Mr. Reddy made came from many different culinary traditions, and he invariably grinned as he explained the recipes and prepared the food. Episodes began with the motto “Loving. Caring. Sharing. This is my family.”
