I have recently read a weight loss related article in the New York Times by Mark Bittman called “Is a Calorie a Calorie?“. It describes a book called “Why Calories Count” by Marion Nestle and Malden Nesheim, two professors of nutrition. It talks about the complexities of diet and nutrition in achieving weight loss from the individual all the way up to a national/political level. It speaks about how diet is much more complicated than just controlling calories. The types of food we eat is important in determining weight loss as well.
