Quite often published pop health advice is only describing an ideal or optimized situation, and is out of context from real life risks/benefits. For example, the health benefits of walking WHENEVER you can--far outweigh the "warning" to not walk after you eat. Eating and walking didn't seem to hinder the Roman army from conquering their world, even if digestion was not optimized. WHAT you eat and how much is more important any of these "how to, when to" issues.
