I think your data is a little old. The undernourished, defined as fewer than 1800 calories per day, has steadily declined from 2000 until 2019, and then risen very slightly as a result of Covid. There's about 660 million that meet this threshold. Global malnutrition really has gotten significantly better over the past few decades. https://ourworldindata.org/hunger-and-undernourishment
