Down five pounds since I started two weeks ago.

Yep, thats what I thought this thread was about. I need glasses. Anyway I started 2 weeks ago and don't have anymore problems with constipation.

I'd rather pack pine needles in my colon.

From bottom up...

Wrong.

It's a combo of insulin and the type of calories you eat (sugar? Carbs? Fat? Protein?)

It's impossible to get fat on a caloric deficit

.

No, it's not...

Proof?

When sugars and carbs are taken in what decides if those are stored or burned immediately?...

You are so wrong... If you force your body into survival mode it will actually put fat in place of muscle. Yes, I
guess you would lose weight but just not lose fat.

I've been doing this for right at 2 months now. Started right after Christmas. 24 pounds down. Weighed 211 this morning. Hopefully a month from now I can crack the 200 mark. I have not seen the low side of 200 in probably 25 years. Goal is in the 185-190 range.

My window is now between 10:30 AM and 6:30 PM for eating and drinking anything but water. My sleep is much better, as acid reflux was a huge nightly problem. That has pretty much disappeared from my life. I'm also on high blood pressure and cholesterol meds. Hoping to kick those to the curb in the near future too!

Congrats! Are you working out as well?

Calories in Calories out. It's impossible to put on weight in a deficit.

There is a HUGE difference between eating below your BMR and going into starvation mode. In addition, when your body kicks into ketosis from fasting after a few days, it does burn fat, not muscle. Actually starving to the point of your body burning muscle is something that very, very few humans in first world countries experience and no one on this board needs to worry about most likely.
