It's been great; substantially increasing my fat intake has led to a noticeable increase in energy levels and recovery. Initially cutting bread and oats was difficult, if only due to breaking long-standing dietary habits.
As far as carbs go, cutting grains and starches literally forces you to eat more vegetables and fruit. Not a bad thing, either. I've got two huge Tupperware containers full of chopped broccoli and cauliflower filling and emptying in the fridge at all times now. I'm making more trips to the grocery store, but it's not a big deal; it's usually the staples: eggs, veggies, whole milk (not Paleo, but I'll be fucked if I'm giving my PWO milk up.), etc.
