Crap, I've been using fitday's info on chicken breasts and it is waaay off.

I looked on the back of a package of chicken breasts from a meat shop, and Fitday's numbers for for a small breast are double what the package I bought say for an average breast. The proportions are right, but I've probably been eating half as much chicken as I should have.

Are there any other foods that are way off on fitday that I should keep an eye out for?

hmmm I looked up nutrition facts online for Chicken for a 4oz breast...

Fitday...4oz chicken breast = 34g protein
online nutrition fact 4oz breast = 21g protein



ummmm

I think chicken farmers have been paying fitday to boost their stats!

Compare grams to grams, not "small" to "average" ... those are subjective terms. Not to mention that it looks like your M&M meat shop has additional ingredients (hence the carbs).

yeah but i checked 4 OZ to 4 OZ on fitday vs. a nutrition site and it was off by 13g protein

Yeah they are marinated.

I don't normally have a way of weighing the food I eat so I usually go by size or description. I think that's pretty misleading to call a huge honker of a breast "small".

That one is a mystery!

Doktervet, keep in mind that M&M probably has a lot of salt and water, so even if they were the same size there's a good chance the calories would be different.

Don't go by the small, med, large. Get a scale and use it. They are only like $10 at walmart.

I guess the only way to label things without nutrition facts is a scale. right???

Yeah, I dont use fitday for its massive database of food. I use it to custom enter all the food I have in my house, and use the label from the box.

Fitday, the label from your food, your scale, waste, etc.

All factors regarding the inaccuracy of counting things to the gram.

The best you can do is do it the same way every time, underestimate protein, and see how things go.

Then how do you put in things like carne asada?

I figured this out...

if you choose the "oz, boneless, raw (yield after cooking)" option, the macros are correct....instead of using "oz, boneless, cooked"

Interesting.

The M & M breasts are actually really small, but fitday's approximations are a bit unreasonable I think.
I guess I just learned that I need to buy a scale and use it.

I've also noticed that their nutrition facts for plain yellow corn are way off. I don't have a can in front of me but the protein was like 3-4x higher on fitday and the calories were something crazy like 10x higher on fitday.

I have probably a hundred custom foods entered into FitDay. Just take the time to do it once and chances are you'll usually eat the same stuff. Then you'll be exactly on.

I'm not saying fitday is perfect. But if you are measuring stuff and comparing the label to what is in fitday, it's always extremely close. If not, I'd double check your measurements/calculations or check your food choice. That corn example could very well be corn + salt + butter.

I have tons of food in the custom area too, I just made one for chicken so I wouldn't have to worry about it anymore (1oz of chicken has about 45 cals, 2g fat, 0 carbs, 7.5g protein...is this about right?)

Yeah just use the custom, although it is hard to grab a scale and weight your food before every meal, just use the serving size, and over a long period of time it will inevitably even out and be what it says on the package.

You can create custom entries. I don't see the problem.
