From what I understand, some people think that eating high fat and high carb together is bad, for whatever reasons.... My question is what constitutes 'high carb' in this case. Are we talking SAD high carb where people are getting hundreds of carbs from grains, or are we talking about Paleo 'high carb', around 150-300 carbs?

I'm curious, because many of us are eating more Paleo accepted foods like potatoes, rice, and so on. Say you have a steak and a couple of sweet potatoes on the side with butter on top. Does anyone actually argue that this is bad in some way due to the moderate carb load of this one meal?

I'd be curious to hear your thoughts.
