Hi Cazzy,
Yes, that is normal.
In the first week, you are losing glycogen and water, but not fat. That's typically why most people can lose a large amount of weight in the first week.
This weight loss can give people unrealistic expectations though, so I think it's important to remind people that they're not losing fat at week 1.
Also, on Lipotrim, you will lose *on average* 14 lbs a month. So if you have two weeks in a row where you lose 6lbs, don't get upset if the third week shows only a two pound loss. The weight loss will fluctuate. It is not a straight linear constant progression.
