You're average caloric intake here is 1656. Call it 1650.

You weigh 262 lbs.

Let's suppose your maintenance is something like 3100 calories at your size and activity factor.

That's a daily deficit of 1450 calories.

There are 3500 calories in a pound of fat. So you're losing almost a half a pound of fat per day.

This coupled with water/glycogen/waste flux and you're seeing what you're seeing. Are you weighing at the same time each day?
