Depending on the calculation, water being lost is going to get reported as muscle loss even though it's just water leaving your body.
If your total weight loss was 16 lbs over 7 weeks I would also say you are losing weight too quickly. Losing 3/4 of a lb every week is still 39-40 lbs lost in a year.
How did you calculate body fat ? 37% at your stats would imply you have no muscle and look 8 months pregnant, which from your description doesn't sound to be the case.
