Re: All calories in One meal per day or Three?

[Guest guest]

Hi folks:

Thanks Bill, an interesting paper we have been waiting a long time to

see! (Two years, perhaps?)

Disappointing to me for a number of reasons.

Can someone please enlighten us as to the significance of the lowered

cortisol concentrations in those fed one meal per day? TIA

Rodney.

All I can say is I had a blood test this week and I go to the Dr. next

week to confer. I apparently really do have a thyroid problem which I

was aware of last year but refused to take the meds and now it is worse

than it was. Also, I have been an IF person 20/4. The nurse who

called really stressed the need for the thyroid meds and that Total

Cholestrol was 247 and TSH was ...I think 47. It had gone down and I

to 1.0 and I had assumed I would not need the meds so since the summer

I did not take them. She also said something about high Calcium

levels. But, I have also been losing weight. I will admit I ate some

cobbler that had butter in the crust the weekend. The test was on

Tuesday and I had fasted part of the day Monday and had nothing from

midnight Monday til the test on Tuesday. Do you think the IF combined

with the cobbler raised lipid levels? I am kinda worried about

this...I will post real numbers after I receive a copy of the test to

throw it out there and see if you folks wanna help and have any ideas.

The reason the calcium worries me is because of the issues related to

any thyroid cancer. I was diagnosed last year being Hypo....The Dr.

this time did T3 and T4. So, I should know more later.
