Don't give up yet. Keep the Faith and Stay the Course. Give your body a chance to fairly respond.

You started a day after I did and our experiences have been pretty similar. Spectacular weight loss the first week then, blam, the door is slammed in our face. Don't misinterpret either of those. You lost a lot of weight initially because of the strong diuretic effect that the switch to an LC diet has. You also lost some fat. Then in the second week your body started reclaiming the water that it shed that it shouldn't have - and you continued losing some fat. The two effects largely offset each other, both on the scale and with the tape measure, and whether you lose a little, stay the same or gain a little is merely an artifact of the particular balance that your particular body achieved this particular week.

Ride it out. It isn't a fair test of this WOE until after at least a couple of months.

Hang in there.
