I found I wasn't ready to skip meals until about 5 months into eating paleo/primal.
My body is now frequently telling me it wants to skip meals, and I regularly eat only two meals on non-working days (today I ended a 19 hour fast with ease, following half an hour of yoga, half an hour of strength training and an hour of cardio interval training). This feels completely natural now... but would have been hard to imagine before, especially skipping breakfast.
That said I've been eating more carbs than recommended by PB for weight loss, so I'm sure this would have come sooner had I been following PB more strictly from the start.
So follow PB, and follow your appetite, not your brain!
