1.  Is this a low carb diet?

No, this is not a "low carb diet".  It's a priorities-readjusted-towards-a-more-natural-diet.  There is no "one size fits all" menu for perfect health that will fit every person on earth.  Different people have different needs, but it's just like when you choose beauty products.  You don't know what kind of moisturizer you need if you never spent a day washing your face with nothing but cold water.  Until you start eating natural food in general, you don't really know what specific things you need to eat.  Chances are though, it's whatever your great grandparents would eat, and prepared the way they'd prepare it.

Of course everyone needs carbohydrates.  It's just better to get them from whole, sprouted, and/or traditionally prepared grains than it is from a bleached out slice of white-flour-only bread.

No it isn't.  He studied the eating habits of various groups of people and noted that their health was considerably better with a well rounded diet that included both vegetables and meats.  When grains and starchy tubers were eaten, they were prepared carefully according to time honored techniques that stood the test of trial and error over thousands of years.

Since Price's days, others have followed and improved upon his theories about nutrition.  So when someone says "the Weston A. Price plan" they are talking about the collective knowledge gained by a large group of people, many of whom are scientists, doctors, and nutritionists.  Anyone who tells you that it means eating nothing but meat and animal fat with very little vegetables is grossly misinterpreting him and everyone in WAPF, probably because they are morally vegetarian...though apparently not morally averse to lying.

"Wait and see."  They will give you a long lecture about why you should be counting calories rather than eating right and learning over time how to read your body's signals to moderate your portions.  Sometimes people can be extremely discouraging.  Once, when I told someone that I'm losing an average of 10 kg. per year, they told me that it wasn't fast enough.  Forget that I had been gaining weight for 14 years...they felt I wasn't losing weight fast enough, and therefore it must mean that my diet doesn't work.

...

I've lost 5 kg. since that person said that to me about 6 months ago.  I think it's funny.  At the same rate, I'll reach my insurance-ideal weight within 3-4 years.  They're still the same weight they were when I spoke to them.

Wait and see.  That's all you have to say and all you have to do.
