I recently (last 6 months) added potatoes in to up my carbs, mostly to fuel my workouts. Since adding them in I've only gone down 5lbs on scale, but almost 2 pant sizes, so still leaning out.It seems pretty common in the paleo world from my experience. Those last 10 lbs are hard in general but I have seen a number of "paleo" people drop 60lb+ steadily and it stops about 10-15lb short of being truly lean - what I consider 8-12% body fat on a male. Picking up more potatoes, fruit, and beans (black beans +1) really helped me lean out more awhile back. I think adding more good carbs in and being conservative on pointless fat intake from oils and butter is a big help towards the end. In fact I find about 400 calories of black beans a lot more satiating than most fat proteins of the same value. Really, the same with potatoes ..400 calories of potatoes is a lot of food. Meanwhile I can tear through 800 calories of steak or chicken legs easy. Maybe it's just me though.. but I think the classic high fat paleo design is hard for a lot of people to get the last 10-15lb off.
