My first guess looking at your food is salt from things like cheese, sausage and bacon. My weight also does a 2-3 lb bounce from morning til bedtime, so that part is absolutely normal. Let's look at it this way: your maximum fluctuation, 4 lbs, is 1.5% of your total weight. Is 1.5% worth the headaches you're giving yourself worrying over it?

Another way to look at it: you know that there is no way on earth you can gain and lose 3-4 lbs of fat or muscle in 12 hours, so that weight absolutely has to be water (and of course, the steak or chicken still being digested from dinner). If you were female, you'd know that you never shop for shoes late in the day because things like water, salt, gravity and heat make your feet swell! So for you, just don't get on the scale before bed and you'll be fine.

One thing you might like to do if you haven't already is go to www.fitday.com and start entering your food there. Your protein looks good, but your carbs might be closer to zero than they need to be, and your fiber is probably low. A nice tip: you can subtract the fiber grams from the carb grams listed for any food!

Also, the water you drink will dilute the readin on your ketostix, so don't worry if the color is light. It's even possible to not register at all but still be in ketosis just because of hydration.

Have some more veggies, make sure your calories are at least 2300 (10x body weight), and relax and enjoy this WOL. (way of life)

Cheers!
