Hello Momof2!
I went to see my OB/GYN about two weeks ago (about my PCOS) and complained of the same thing. I'm 34yr old, 5'3" and 270lbs. As a side note - My husband and I have no children nor have we tried ttc yet - another reason I visited my OB/GYN. I've had a weight problem my entire life and I'm sure PCOS since 10 when I started menstruating.
I'm wondering if you have acanthosis nigricans, patches of darkened skin on the back of the neck, under the arms, and/or in the groin area. I discovered, not too long ago, that it is a sign of high levels of insulin which means one is most likely insulin resistant even if it isn't showing up on tests. My fasting glucose level is 75 - within the normal range but, I have many other symptoms of insulin resistance including acanthosis nigricans. I've had those dark patches since puberty and remember my mother trying to scrub off "the dirt" on my neck with rubbing alcohol (poor thing had no clue).
So, given all these factors my doctor suggested a low carb/paleo type diet. I've been reading a load of book on this subject. To name a few
Protein Power Lifeplan, Life Without Bread, NeanderThin, Good Calories - Bad Calories. It's quite fascinating and as soon as I heal from a recent tonsillectomy/adenoidectomy (needed thanks to allergies - I swear there is a connection between allergies and my insulin levels...I digress).
To answer your main question, It seems one has to keep their fat intake high and protein intake moderate - high in order to survive a low carb diet. We have it drilled into us that fat is bad. Many are now arguing if even saturated fat is as bad for us as 'they' say. It seems many people follow a low carb diet but still go along with the low fat idea. Most ultimately begin to think low carb doesn't work but, the key many maintain is keeping your fat intake high, carbs low (and that depends on the person - you have to experiment with the grams daily to figure out what works for you) and the protein moderate to high.
I'm going to give this concept a good honest try to see if it works. It will be hard to not keeping thinking things are too fatty but, I have nothing to lose. None of the traditional diets are working for me. I'll go to my GP in 6 months and have a CBC done. Of course, my fear is that my numbers will go through the roof but remember triglycerides may be fat in the blood but, they're caused by carbs.
Can you tell this has been on my mind a lot recently.
