Not sure - some combination of shakes & low carb food, at least to begin with. Shakes don't really fit in with the paleo ethos as they are processed, but until I work out some way of eating healthily at work then they should keep me on the straight and narrow.
I know that I *can* have carbs if I want, but that I have to plan them, and compensate for them eg planning to have a traditional dessert or birthday cake etc for a special occasion would mean a carb-free day before and very low carb day after, to avoid the slippery carb slope.
Using myfitnesspal constantly to ensure that over a week my average calorie intake is right will certainly feature in the plan!
