The early losses have nothing to do with fat loss. When you go into ketosis, your body depletes glycogen stores in muscles and in the liver. Glycogen binds a lot of water. That adds up to 6-9 lbs normally. Medifast is only mildly ketogenic, so there may be differences between people and when they deplete glycogen stores. Even in ketosis you need to have a deficit of 3500 calories to loose 1 lbs. So, you can calculate your weekly losses based on how much you burn versus what you put in. Ketosis may lead to preferential fat loss over muscle. No scientific proof, but that was my impression.
So, no need to get frustrated. Medifast is an easy diet in my opinion and you just have to buckle up. Weight gained over a period of time also takes time to loose. There will be higher losses and lower losses. But a year from now you will reap the benefits.
