Nope. I used fitday once to see what the hype was and never returned. I think it can be a valuable tool for some people for approximating things and making sound guesses about where to go from there, but for me I could see it easily leading to obsessive type behavior or reinforcing an atomistic and mechanistic view of bodies and nutrition that, to me, is antithetical to where I am at with primal eating/thought. I focus more on my body's signals to determine what I need, the quality of food, and how it was prepared to guide my eating choices. The only nutrients I am conscious about trying to consume are magnesium, iron, B12 and D because I am deficient in those, per blood tests, but that mostly consists of "you should probably eat more of this pate or dark chocolate or take your sweater off outside, huh?" I remind myself, but don't stress about it if I end up not following my own advice sometimes.

No. Really don't care. All we eat is protein in the form of muscle or organ meat or eggs or fish... and fat in the form of coconut oil, animal fat, olive oil, butter. And a few veggies along with our daily salads. We eat until we are somewhat full but not overly so. My body tells me that I am not deficient in any food nutriet. We do supplement with 5000IU Vit D3.

Eating for us is just a necessity...not something done for gastronomical pleasure....although eating to satiety is pleasureful....and eating paleo engenders a nice state of well being.

No, I don't. Initially, when I was logging my food on Fitday it would drive me crazy trying to micromanage it or wondering if the guy at Dunkin Donuts put 1/4 cup of milk in my coffee or did Starbucks really use non fat milk for my latte. Then I got over it. I used Fitday, and now Livestrong, to give me an estimate so I can make better decisions. I know it's not 100% accurate, but I also know that while tracking my food over the last 6 years I learned a lot about the ratios of what I eat and how they affect my body. I learned a lot about what foods have too much sodium or carbs. It's a tool to assist me, but I also use my common sense. I don't expect the information to be 100% accurate.

I only used fitday because I was curious from a scientific perspective. Knowing an approx intake of macronutrients and regular nutrients allows me to check for any potential deficit in any one nutrient, like magnesium. It also allows me to better understand scientific data gathered from other groups of people and how my diet might compare. It also allowed me to diagnose symptoms I was having from magnesium deficiency as actually being from magnesium deficiency. Before that, I has assumed I was just getting old, but thanx to fitday, and a trial run of magnesium pills, I found out I was not THAT old LOL! It really doesn't matter the exact numbers, buy fitday allowed me to see where trouble spots might be and explore the data further. However, for the most part, I just eat what I want as long as it is healthy.

I really have no idea and for me that is a huge feature. I like not having to care, it makes things easy. I just try to keep things varied.
