Santa should have cookies AND veggies if he's going to walk

I am utterly charmed by this analysis of Santa's energy expenditure while delivering presents.

According to our Holiday Calorie Calculator, if Santa had a cup of carrot and celery sticks at each household instead of cookies and milk, he would only consume 50 calories at each house and would only be eating 4.6 billion calories. Because he is burning off 13 billion calories by walking, he would actually lose all of his weight and disappear. A combination of veggies at most households and cookies or skim milk every few households would keep him in energy balance.
