Humans are incredibly inefficient power generators. I can buy 1kWh of electricity from the grid for about 18 cents (generation…transmission is extra).
I don’t think I can buy 870kCal of food for 18 cents. Certainly not a healthy source. And that’s even assuming 100% efficiency. Any high school physics student will tell you that won’t happen.
1 kilowatt hour is about 870kCal.
