That makes absolute sense for all the hunter gatherers out there. Sadly, todays food uses a lot of petroleum for transport, harvesting, and planting in addition to the energy and oil that goes into the fertiliser, pesticides, irrigation, and the energy to warehouse, process, package and merchandise the product. If ethanol from corn is essentially energy neutral, imagine how energy exhaustive meat products are! :shock: Think how much less oil would be used if everyone was the ideal weight and vegetarian.
That said, we need to eat to live, and a well exercised body is
more energy efficient. In this sense riding the bicycle is probably an excellent choice, especially compared to running on a powered treadmill, in a dedicated building, that you have to drive to get to!!!
Had a great chili bean medley and rice for dinner.
