We now have too many calories and too many of those calories are of low quality. One in three Americans is now obese. Over the last thirty years the number of calories we eat has increased, but so has the number of those calories that come from highly processed foods. In this light, we would do well to eat fewer processed foods and more raw ones. This is not a novel insight (Such foods, after all, tend to have more nutrients such as B vitamins, phytonutrients and minerals and so are good for reasons having nothing to do with counting calories). But what might be novel is the realization that in eating such foods you could lose weight while keeping the precise tally of the calories you consume exactly the same. However, this realization comes hand in hand with another, namely that how much weight you lose depends on the biology of the plants and animals you choose to eat and who you and your microbes are in ways we are only beginning to understand.
[As a whole the article is interesting. It still comes down to you figuring out what works for you, and that whole foods (anything that still looks like it did when it grew) are better for you and processing food more than a bit is not a great idea.]
