My plan is to stay well under 20 carbs until/unless I hit a stall, then up my carbs to 20-25. From personal experience, my body doesn't need a lot of carbs to gain weight, so I'll be very cautious in testing my transition to OWL. I have started adding nuts and avocados into my diet now...while still staying well-below 20 carbs/day, as I need to raise my HDL cholesterol. My guess is that I won't even think about OWL until I am within 10-15 pounds of my goal weight.
