Great article on endurance training & metabolism by Tom Venuto

One of the main bits I liked.

Here’s the catch: It doesn’t seem to be the large amount of cardio alone that’s causing the adaptation. The slowdown in metabolism happens the most when you’re doing extreme amounts of cardio AND you’re severely cutting calories at the same time.


It appears that you can cut calories fairly aggressively and not experience any serious metabolic consequences if you’re eating plenty of protein and your training volume is conservative, perhaps just 3-4 days a week of lifting weights with minimal cardio.
It also appears that you can do a LOT of cardio without consequences if you fuel yourself appropriately. Just look at endurance athletes – they’re doing a ton of training, but they’re also eating a lot more to support the training demand.
