Fit Day vs Labels
 

I was wondering how accurate labels are on foods. I have noticed that when I try to customize foods, Fit Day will come back saying that the amounts cannot be correct for the calories. This is making it really confusing for me to count carbs. Also, how accurate are the figures on Fit Day? Who do I trust? For example I purchased some Avocados and the Nutrition facts state that there is 3g of carbs per serving and 3g of fiber. So do I count that as no carbs? Fit Day has different figures for avocados. Any one else running into this situation? :confused:

i never trust fitday.
I dont know, it just doesnt follow the same standards as Atkins.
Avocados surely have carbs, like about 4 grams for 1/2 avocado. I trust Dr. Atkin's carb gram counter.
Its in a small book form.
Also, there is a carb counter at the website: www.atkinscenter.com
good luck!

...avocados
 

Therre are different types of avocados ... Haas has less carbs ... as for any thing else ... ???

Avocados are a good example of why it's difficult to accurately count carbs when measurements are given in increments like one-half. The carb count will depend upon the weight and variety of the avocado. The Nutrient Database from the USDA lists three types of avocados — all with slightly different level of carbs. I believe that Fitday has adapted their information from this database. I have found it common for package labels to list amounts that differ by small, or large, amounts. Part of the problem is the way producers are allowed to round values down so that small portions may be zero or less than one gram when a reasonable portion would contain many grams of carbs.

If you'd like to try using the USDA database, I've put a simplified version of it on one of my pages. Look for Instant Carb Counter near the top of the page. Or you can goto the UDSA site and access it from the net, or download a version that works in a Palm Pilot — very portable and convenient. (I'm currently over in France cooking in a Michelin-starred restaurant and the portable version has been very helpful in the kitchen.)

Thank you all so much. I think that I am going to stop using Fit Day and go back to my old way of keeping track....pen and paper!

Why don't you think Fitday is as accurate as the Atkins counts ? It looks ok to me ... it has both, CA and FL types. For the CA type it shows 12 gr total ,including 8 gr fiber for a net of 4. What's wrong with that ?

Fit Day and USDA
 

I went to both sites and found that Fit Day DOES use the USDA Nutrition Database for its totals. I am going to start from scratch on Fit Day and try to customize as little as possible. After looking at labels on foods, I am trusting them less each day.

In my experience, I've used fitday.com and have always stayed in ketosis at between 20 - 30 grams of carbs per day. My conclusion is that it must be right enough.

Carbs-Fiber=net carbs
 

You are correct red1cutie!

Labels are not foolproof. I have often refigured the numbers on labels and found hidden carbs. There are only three sources of calories in food - fat, protein, and carbs.

The formula is: Number of total calories per serving - fat calories-protein calories-carb calories = zero.

To get fat calories, multiply number of grams of fat X 9 calories
For protein, multiply number of grams X 4 calories
Carbs, multiply grams X 4 calories.

For example a food with zero carbs lists per serving:
80 calories per serving
Fat calories 45 (5 grams x 9cal./gram)
Protein cals. 28 (7gr. x 4 cal./gram)

Leaves seven calories that are unaccounted for. I assume that those are carb calories.
