I lost a lot more the first week than the second. You have to understand that the weight you are initially losing in the pre-op diet is water weight. It's simply the water your body had stored with your glycogen. The way the pre-op diet works is it puts your body into a state of ketosis. This happens when your body is completely depleted of glycogen. Each gram of glycogen in your body is bound to 3-4 grams of water. As you deplete your glycogen stores, that water is flushed from the body. Usually it's a total of about 4-10 pounds of water. That happens quickly in the first few days of the diet, as your body transitions into ketosis. After that, you start burning fat for energy, but you have to burn 3500 calories to burn one pound of fat. It's unlikely that you are expending 3500 calories worth of energy in a day, plus you are taking in SOME calories on the pre-op diet, so you are going to see a lot less of a loss once you are in ketosis.

So you lost no weight in the second week? that is unusual for it to be zero for a whole seven days in a preop. but what Jamie says is true. if you aren't truly stalled, but dropping in fits and spurts that is normal. don't expect to drop every day, that is unlikely. if you haven't lost anything for a whole week then you are stalling. weight loss usually looks like a set of stairs, not a down slop.
