Years ago I attended a health seminar where the presenter stated that the digestive system uses lots of energy to digest food. He (and other authors I've read) suggested the idea that generally speaking, when your body doesn't have to spend energy digesting it can do other things better. (ie, detox would fit in with this) Though I can't say I understand how or why this would work, it's seems a reasonable assumption.

I read some Russian articles about research carried out about 40 years ago about the most efficient way to survive on limited food if one gets lost in wild nature. Their conclusion was that one should not ration food. One should just eat normally until one runs out of food and then fast until normal amount of food is available. And fast here means literally zero calories. One should not eat berries, mushrooms etc. Those triggers digestion that spend more energy that will be extracted from snacks.
